Analog User Answer Forum Question 1: The MIDI control of my Original MIDIJACK-equipped analog synthesizer is great but the keyboard on my analog synthesizer doesn't work anymore. What's wrong? Answer: MIDI On mode
has probably been selected. If the synthesizer is receiving MIDI, the
Original MIDIJACK bypasses the local (built-in) analog keyboard. To
turn MIDI off, hold the MIDI function button down for at least a half a
second (>.5 seconds) and the MIDI will be off. In this MIDI Off
mode, the built-in keyboard on the analog synthesizer will work, as
well as all normal factory performance controls such as pitch bend,
portamento, etc.. Since the Original MIDIJACK provides proper multiple
note triggering and last note priority with a 4-note buffer, it is
often best to use MIDI control even if playing live without a computer
sequencer. Old analog synthesizers often have dirty electrical contacts
in the keyboard, or even worse, completely rotten rubber and metal
mechanisms, which causes missed notes or double-triggers. Use of such a
primitive keyboard with a range of only a few octaves is pointless when
the analog synthesizer is equipped with a Original MIDIJACK which has a
128-note range. Question 2: My analog synthesizer has a MIDIJACK but it won't receive MIDI. What's wrong? Answer: The MIDI may
be connected or selected incorrectly. Make sure the MIDI output of the
controlling computer sequencer or MIDI keyboard is connected to the
MIDIJACK with a known good MIDI cable. Do not use the MIDI through
function on any MIDI device, ever. Make sure the MIDI channel
is correctly selected to be the same as the channel on the MIDI
controller. Question 3: My analog synthesizer plays in tune with MIDI, but with the MIDI off, it no longer plays in tune. What's wrong? Answer: The old
analog synthesizer
needs calibration but the MIDIJACK may play it in tune perfectly due to
it's infinite analog scaling. It should really be calibrated by a
service center specializing in the repair of older analog
equipment,
but if it plays in tune with the MIDIJACK, you may be able to use
it as it is with MIDI and never use the built-in keyboard at all.
Question 4: My MIDIJACK-equipped analog synthesizer plays in tune with it's own built-in keyboard when the MIDI is turned off, but when the MIDI is turned on, it's out of tune. What's wrong? Answer:
The MIDIJACK needs calibration to achieve proper intonation. This can
be done by the Analog User with a keen sense of pitch. Read the chapter
of the MIDIJACK Analog User Manual entitled "Analog Calibration Mode". Question 5: My analog synthesizer has a MIDIJACK and sometimes plays the wrong note or has a note stuck on after the music has stopped playing. What's wrong? Answer:
The Original MIDIJACK is a MIDI interface for analog monosynths. These
synthesizers have only one voice and should be sent monophonic MIDI
notes only. This means that only one note at a time should be sent to a
MIDIJACK-equipped analog synthesizer, and computer sequences should be
recorded with this specific requirement in mind. Many previously
recorded computer sequences contain chords instead of single notes.
Since MIDI is a serial interface, these notes cannot be sent
simultaneously. The notes will be sent one at a time in no particular
order, as a string of note on commands without any note offs, while the
monosynth is playing one note at a time. There is no way of knowing
which note of the chord will sound at any one time. Making matters
worse, the MIDIJACK puts all of these incoming notes into the 4-note
buffer, then matches them up with note off commands when they start
arriving. When the MIDI note on/note off data no longer makes sense,
various active notes may linger in the buffer. When this occurs causing
a stuck MIDI note, the user may push the MIDI function button to stop
the stuck note. One considerable defect of the MIDI specification is
that it supposedly has 16 channels, when it really has only one.
Compared to multichannel audio mixing consoles and televisions, the
MIDI spec has really misappropriated the word "channel". All MIDI data
is sent on a single wire regardless of the "channel". One channel of
MIDI data is sent on one wire. Sixteen "channels" are also sent on one
wire, but at a greatly reduced speed due to the reduction of usable
bandwidth. The result: All MIDI devices set up in a standard "star"
configuration have to read and understand the MIDI data of all 15
irrelevant channels while set to only one "channel". Not only does this
drastically reduce the bandwidth of the datastream, but it also
increases the data processing chores required by all MIDI devices in
the setup, in some cases by thousands of times. An audio signal
processor set to receive a single a MIDI program change once during the
middle of the song only (after doing nothing for two minutes), instead
has to read 3,750,000 bits of data while waiting for the one command it
will get during the song being played. The result may be poor, slow DSP
(Digital Signal Processor) performance damaging the audio, and
different results entirely when some MIDI tracks are muted, due to
suddenly increased bandwidth of the datastream. If the MIDI setup is
configured in the daisy chain configuration where the MIDI through
function is used, the results are bound to be a hundred times worse due
to added MIDI delays and distortion of the MIDI signal by pointlessly
optoisolating the MIDI signal several times turning a sharp, clean
digital string of zeros and ones into a sleepy analog sine wave that
may be interpreted incorrectly and differently by the MIDI slave
devices. In such a situation, synchronization between MIDI tracks is
lost, and the feeling of the music wanders as it plays. To maximize
performance in a MIDI setup with multiple instruments, the MIDI data
should be channelized by any means available so that one instrument
receives only the channel data sent on the channel to which it is
assigned. It will still receive potentially unnecessary MIDI clocks and
system exclusive data, but for now, this is as good as it gets. Question 6: I have an Original MIDIJACK installed in my Micromoog and it never plays in tune. The intonation of the keyboard is always bad. What's wrong? Answer:
The Micromoog never played in tune with anything except its' own
keyboard. Controlling externally via CV/gate jacks always caused the
notes to be out of tune whether it was 25 years ago from a Minimoog or
more recently with some sort of MIDI controller type of device. It has
been said to be not 1 volt per octave, but rather about .9 volts per
octave due to some design error. This is no longer a problem. Do not
underestimate the versatility of the MIDIJACK. It is all hardware. If
your Micromoog has the problem of being .9v/octave instead of
1v/octave, it can be corrected with a quick adjustment on the MIDIJACK.
Play a few notes on the Micromoog through MIDI. If the notes are all
sharp as you go up, like the whole keyboard has steps that are too far
apart, then it is less than 1v/octave. The
solution: The Original MIDIJACK
has a scale adjustment trimmer that affects the musical
intonation of the analog synthesizer while it is under MIDI control. It
is less than one inch away from the MIDI function button and may be
adjusted by inserting a small flat blade screwdriver into the control
panel opening. A Synhouse Pocket Screwdriver fits perfectly. The scale
adjustment trimmer may be set by ear if the Analog User has a good
sense of pitch. A MIDI controller keyboard should be connected with a
MIDI cable to the MIDIJACK and the audio output of the Micromoog to a
sound system for monitoring. The MIDIJACK should be in MIDI On Mode and
set to the same MIDI channel as the MIDI controller keyboard. While
playing alternating notes on the MIDI controller keyboard that are an
octave apart, the user can turn the scale adjustment trimmer very
slowly until the proper one-octave interval is heard and the entire
keyboard plays in tune. It may be easiest to hear the tones clearly by
adjusting the Micromoog so that the filter is open with the frequency
set to maximum, the emphasis set to minimum, and the envelope
generators set to sustain, without any vibrato on the oscillators. An
extra help would be to use a MIDI synthesizer or sample playback
keyboard as the MIDI controller and listen to its sound output as a
reference tone to match the Micromoogs' intonation while adjustments
are being made. A low note may be played on the MIDI keyboard while the
Micromoogs' master tuning knob is adjusted to bring the two sound
sources into tune. Next, play higher octave intervals of that note, and
slowly turn the MIDIJACK scale adjustment trimmer until the entire
keyboard plays in tune. For the Micromoog to work properly, the trimmer
will have to be turned about 10% down, or counterclockwise, from the
Synhouse factory 1v/octave setting. With this altered setting, the
MIDIJACK should be putting out MIDI notes 0-127 at a scaling interval
of .9v/octave. You can shrink or stretch your scaling from 0v/octave
(not too musical) to approximately 1.2v/octave. Actually more than
that, you could turn it all the way up to 2v/octave but the MIDI notes
above 64 would be clipped and all the same pitch. The MIDIJACK is
designed this way because most old synthesizers are out of calibration
in one way or another and this is one way to try to bring them back
into adjustment. Additionally, it allows the MIDIJACK to work in
instruments that have exponential oscillators other than 1v/octave,
such as EML (Electrocomp 101 and others) and EMS (Synthi AKS and
VCS-3). Question 7: I got a friend to hook me up with someone that's selling me his Moog Source for $600... so technically with the MIDIJACK I could get a Moog Source with MIDI $699? Answer:
Yes. Question 8: Nifty small thing - that MIDIJACK. Will it be suitable for my Multimoog? Answer:
Yes, the Original MIDIJACK. Question 9: Will the MIDIJACK work for my Korg 800 DV (I think it has no gate / CV or any input "holes" at all)? Answer:
Yes, you can use the MIDIJACK II: Hertz so good! The lack of CV/gate
jacks is no problem. The MIDIJACK II works with a lot of synths that
don't have an analog interface, such as the Moog Prodigy documented on
this site under Analog User Modifications. The Korg 800 DV is not
listed on the list of known compatible synths for a technical reason:
It is not a monosynth, strictly speaking. The DV stands for dual voice,
which in those days probably meant something. Now, you would be more
likely to stack the oscillators into a super-fat unison mode and you
could use the MIDIJACK II to run it as a MIDI analog monosynth. If you
really wanted two voices, you could use two MIDIJACK IIs and set them
to separate channels and use it as a two-voice multitimbral analog
synth. Question 10: I have a Roland MC-202. Is it possible midify it with your MIDIJACK? Answer:
Yes, the Original MIDIJACK. Question 11: Am I overlooking something, or does the MIDIJACK NOT support pitchbend or modulation functions? Answer:
The MIDIJACK does not support pitch bend or modulation functions.
Question 12: Someone told me that the MIDIJACK does not work with MS-10 and MS20. Is that true? Answer:
No, it is not true. The Original MIDIJACK works with the Korg MS-10 and
Korg MS-20, and the MS-50 as well. The MIDIJACK II is also compatible.
They are also the only way to convert those synthesizers to MIDI for
the price of a MIDIJACK. There is an installation article posted on
this site under
Analog
User Modifications. Many things have been said in public and in private
about the MIDIJACK that are not true. The listeners would do well to
consider the motives of those who are making those statements about the
MIDIJACK and refer all questions to the e-mail address at
the top
of this page. There is only one up-to-date and reliable source of
information about MIDIJACK usage and compatibility: Synhouse. Question 13: I have a Korg Polysix. Will the MIDIJACK work for my synthesizer? Answer:
The Original MIDIJACK is monophonic because it has been
designed specifically
for analog monosynths. The Korg Polysix is polyphonic. If it could be
installed in a Korg Polysix, it would be impractical because you would
only have one voice available. Question 14: If I purchase the MIDIJACK will I be able to install it in a Memorymoog? Answer:
Yes, but you probably should not. The Original MIDIJACK
is monophonic because it
has been designed specifically for analog monosynths. The Memorymoog is
polyphonic. If it could be installed in a Memorymoog, it would be
impractical because you would only have one voice available. Question 15: Question for you....is it possible to put a MIDIJACK on a Roland TB-303? Or is the DIN plug that are on the stock 303s the same thing? Answer:
Yes, the Original MIDIJACK works for the Roland TB-303 Bassline. No,
Roland never put MIDI on a TB-303. The DIN jack it has is for Roland
DIN sync, which does not play analog music at all, just sends a timing
clock to the built-in digital sequencer. The MIDIJACK will allow you to
use your MIDI computer sequencer (Cubase, etc..) or MIDI keyboard to
play notes on the TB-303 over a much greater range than the TB-303 can
do by itself. It converts the TB-303 into an analog MIDI monosynth.
Question 16: Can I use the MIDIJACK to MIDI-up the Juno-60? Mine has DCB. Answer:
No. There are two reasons. The primary reason is that the Roland Junos
are digital synthesizers and Synhouse deals strictly in analog. The "D"
in DCO stands for digital and the "D" in DCB also stands for digital.
The secondary reason is that the Original
MIDIJACK is monophonic
because it has
been designed specifically for analog monosynths. The Roland Junos are
polyphonic digital synthesizers. You should be able to find a source
for a Juno controller on the Synhouse Internet Links page. Question 17: I want to place a order, can you inform me about payments (I live in Europe). Answer:
You can order securely online from the product pages and ordering page
on this website and shipping is free worldwide. It is unfortunate that
the European companies won't give you that. Question 18: A friend want to install a MIDIJACK in a Multimoog have you any plan to do it. Answer:
Online, no, but there is no need for it. The synth is not very common
and no more online articles are planned at this time. The installation
method is a snap to do, and is absolutely identical to the Micromoog
already on this site. The Original MIDIJACK comes with 3 manuals which
describe installation in any compatible synth, including the Moog
Multimoog, which is very easy to do. Question 19: I want to put MIDI on my ARP Odyssey (mk1). Is this possible? Answer:
Yes, it is possible with the Original MIDIJACK. You must follow the
instructions and locate the internal CV/gate points inside the synth
and connect the color-coded MIDIJACK wires to those points. That synth
never had CV/gate jacks, and it is pointless to drill a lot of holes to
add an obsolete interface to a classic synth. Put a MIDIJACK on it! Question 20: Hello, I recently purchased a TB-303, without any mods. I'm interested in hooking it up to my PC so I can sequence using it using my software. Does the MIDIJACK work with the TB-303, and will it enable the PC sequencer to control all the features of the TB303? Answer:
Nothing will control all the features of the TB-303 from a PC. The
Original MIDIJACK will work for the TB-303. If you put it in the
TB-303, it would become a MIDI analog monosynth with a 128-note range.
If MIDI were turned off, it would operate as if unmodified until you
turn the MIDI on again. It might not fit your needs. It is universal.
There have not been any specific synth functions controlled by the
Original MIDIJACK, because it is for over 100 different synthesizers,
not just one. Minimoogs don't have accent, Odysseys don't have
sequencers, and TB-303s don't have arpeggiators. What they all have in
common is a combination of CV and gate control from their own
keyboard/sequencer or external jacks. The Original MIDIJACK taps into
that. It will not give it all the MIDI control Roland should have given
it in 1983. Question 21: I'm searching for a MIDI interface for my TB-303. Is it possible to control the filter (cutoff range) of the TB-303 with the MIDIJACK interface? Can I use the sustain pedal controller to do this? I need an interface to control the filter via MIDI. Answer:
See the answer to question number 20 above and see the Synhouse
Internet Links page for a source of MIDI filter control. It will
not be
an internal MIDI retrofit as there is no such internal MIDI retrofit
with filter control. Please note that no company could ever control the
filter with a sustain pedal. The sustain pedal is for controlling
sustain with a pedal, hence the name, and it is supported by the
Original MIDIJACK. The filter cutoff frequency is a continuously
variable control which the on/off action of the sustain pedal would not
be suitable for. Question 22: I want to buy a MIDIJACK for my Yamaha CS-15 but it has 2 independent voices. Do I need two jacks? Or will one handle both voices? Answer:
The MIDIJACK II is made especially for all Yamaha CS-series monosynths
(except the Yamaha CS01 which claims to be analog but isn't, behind the
panel that says VCO, it has a Digital Tone Generator instead of a Voltage-Controlled Oscillator) and some Korgs. The
MIDIJACK II is monophonic. If you installed two of them you
would have a multitimbral synth which would receive on two
independently-selectable MIDI channels. At only 1" x 3" each, the MIDIJACK
II units are very small, so you
could
fit two of them into a Yamaha CS15.
It is wired behind the original
CV input jack. If your synth has two of those, just put one MIDIJACK II
behind each CV input jack. It can be self-installed with the 3 included
manuals or factory-installed at Synhouse L.A.. Question 23: Just want to ask for the nearest dealer for Austria. Answer:
Synhouse.com is everywhere. You can order securely online from the
product pages and ordering page on this website and shipping is free
worldwide. Question 24: I picked up my Moogs from the worst repair shop ever. He said they would install the MIDIJACK. He charged me for the d**n chasis punch...so I bought them their d**n tool...total was like $311. For absolute s**t. I had parts put in like new input jacks, I dont mind paying that..but the d**n labor at 35 an hour...he also didn't charge me for like 10 hours...but that's cause he blew 3 parts in the Prodigy, and had to figure it out. I am giving up on the repair shop. He got my Prodigy working again without the MIDIJACK, but when he hooked it back up it didn't work again. He unhooked the MIDIJACK and at least it worked this time (first time he had blown 3 integrated circuits). Now as for my Moog Source...the MIDI works. Answer:
You should have sent them to Synhouse for Factory Installation. Question 25: I wonder if the MIDIJACK works with older, non-MIDI drum machines as well as analogue synths. I'd particularly like to know if it works with either the LinnDrum or Oberheim DX. Answer:
The Original MIDIJACK is specifically for analog monosynths. It isn't
meant to work with digital drum machines such as the LinnDrum or DX.
There are no plans to develop a specific interface for either of those,
mainly because there is very little interest in them and they already
had very reasonably priced MIDI anyway. Question 26: Can I use a MIDIJACK for my Minimoog ? Answer:
Yes, the Original MIDIJACK. Question 27: Will the Original MIDIJACK work on a Roland Jupiter 4? Answer:
The Original MIDIJACK will work fine for the Jupiter-4 but it will be
monophonic because the MIDIJACK is designed specifically for analog
monosynths. It has been installed it in the SH-1 and SH-101 and it is
quite easy to do. Question 28: I've a Crumar DS2, with only gate in, out; I want to use it by MIDI, can I use your MIDIJACK? Answer:
The Original MIDIJACK is designed for analog monosynths, and the Crumar
DS-2 is not analog, the DCO is digital, not voltage-controlled, so it
will not work for this synth. You could probably wire the CV wire to
the VCF to sweep the filter with MIDI notes, and use the gate wire to
trigger the gate, but not the main oscillator. Question 29: I own a Roland Juno-6 and would like to fit MIDI on it. Do you make any MIDI to DCB converter unit? Answer:
Synhouse does not have anything for digital (DCO) synths or any
polysynths, strictly analog monosynths. The Juno-6 doesn't have DCB
anyway, and a converter will not help you. Question 30: Even if the Juno-6 hasn't got a DCB input, someone told me that it is possible to fit a DCB input connecting something to the Juno-6 and then using a DCB converter. Is this true? Answer:
Yes, it is true but this type of modification is rarely done and will
never be done by Synhouse because it is senseless. You can check the
Synhouse links page to find a company that will put a DCB interface on
your Juno-6, but it does not make any sense to spend $250 to put an
obsolete interface on a synth then spend another $200+ to get a
converter to convert MIDI to DCB. What would you do next, convert your
PC and Macintosh to DCB? Besides, a Roland Juno-6 is only worth
$200-300 in most countries. Question 31: Will the MIDIJACK work for my Yamaha CS10? Answer:
The Yamaha CS10 will work with the MIDIJACK II. Question 32: I recently uncovered a small MIDI keyboard one Yamaha CBX-K1, I have had this knocking about for quite some time but now it is never used. I felt it would be good to have this as a handy CV/GATE keyboard. I am wondering whether the MIDIJACK could serve this purpose. In theory I just disconnect the MIDI out from the keyboard and wire this into the MIDIJACK input. Wire the MIDIJACK power supply in parallel with that supplying the keyboard. Install a few CV/Gate connectors and away I go. The keyboard itself runs on 9v DC or batteries. Any thoughts? Answer:
Although this application has not been heard of so far, yes, it would
work exactly as you described. The Original
MIDIJACK requires at least
+12v DC
but less than +30v DC, regulated or unregulated is fine because the
MIDIJACK regulates the power again. Question 33: I bought an Original MIDIJACK and read all 3 manuals that came with it. It lost me talking about the glide or portamento.....do I have to make another modification for the glide to work? If I just have the glide on at the desired setting on my synth, and play the notes on the MIDI keyboard...will I hear the glide? I really didn't understand the manual. Answer:
That is good that you read the manuals and started asking questions
before starting work on your synth. It depends which synthesizer you
are using. On many synthesizers, the portamento is disabled and doesn't
function while the synthesizer is under external CV/gate control. This
has always been the case with many synthesizers, even though glide is
generally thought to be an oscillator function, not a keyboard
function. The portamento circuit is placed between the local keyboard
voltage and the CV/gate input jacks, so when the jacks are used, the
keyboard voltage is cut off and so is the portamento circuit. The
portamento circuit needs to be rewired to function correctly. On most
analog synthesizers of this type, the original circuit may be isolated
and inserted where it belongs, between the CV/gate input jacks and the
VCOs. The MIDIJACK connections are exactly the same as using external
CV/gate control, so if the synthesizer has no glide while under CV/gate
control, it won't with the MIDIJACK, either. The modification suggested
here is not only a good solution for use with MIDI, it is a good and
meaningful improvement to the instrument overall. Generating glide is
so trivial that it may be slightly simpler to build a new exponential
glide circuit. This can be done quite simply by taking an audio-taper
potentiometer of at least 500K or 1 meg Ohms wired as a straight
variable resistor (so the resistance goes up when turned clockwise) and
connecting one end of it to the MIDIJACK #4 white wire (MIDIJACK CV
output) and the other end to a 10 uF (or greater) capacitor which has
the negative end to ground. The junction of the cap and pot should be
connected to an op amp configured as a buffer-follower. This buffered
output goes to the VCOs. This puts a lag generator between the MIDIJACK
and the VCOs, and you need to find a place to mount the new knob you
have created. If the op amp used is of the standard older variety like
the ones used in the synthesizers themselves, the negative power pin
should be connected to the negative supply in the synthesizer and not
the ground. If this is not done, the op amp will be unable to reach
ground, causing a tuning problem that will be accentuated when the
MIDIJACK is MIDI transposing -36 for super deep bass, but the
synthesizer octave select is set to 32'. A cross between these two
methods that would preserve the original look of the instrument would
be to use the original glide pot on the panel, rewired to the new glide
circuit. Before any work is done, check the synthesizer portamento
first. Some synthesizers, such as the Moog MG-1, Moog Rogue, and Roland
SH-101 have the glide circuit correctly wired in the post-jack position
already. Question 34: I have a Korg Triton MIDI workstation and two Moog synthesizers w/ Synhouse MIDIJACKs. I have 2 monophonic Moog riffs programmed into the Triton's sequencer. Since the MIDIJACK only has a MIDI in and not a through, how do I connect 2 Moogs to the Triton? Is there a splitter like an adapter from Radio Shack which will allow 2 MIDI outs from the Triton instead of 1? Answer:
First of all, it is no mistake that Synhouse products do not have MIDI
through. They don't now and they never will. It is purely intentional.
Synhouse does not condone MIDI through. MIDI through on instruments is
garbage. There were a number of foolish amateur functions outlined in
the original MIDI specification. One such function was Omni mode.
Quoting from the MIDI spec, "At power up or reset, all instruments
default to Omni mode." In 1983, it probably seemed like a good idea to
have every instrument play every MIDI note sent by every other
instrument connected to the system. It allowed music store customers
who knew nothing about MIDI to hear MIDI demonstrations from salesmen
who knew even less about MIDI than they did. It guaranteed that they
would hear sound even if they had no clue what a MIDI "channel" setting
was or how to change it to match on a master and slave. Now in the year
2001 (when salesmen know about .2% more about MIDI than they did in
1983), it is frightening to think of a MIDI system that will play
everything on everything all at once when you first power up for the
day so that you have to go back and reset every MIDI channel and turn
MIDI Omni mode off before you can play a single note sensibly. Another
way the MIDI spec violates it's own sensibility is with MIDI through.
If you look at the MIDI hardware spec and notice the single
optoisolator at the MIDI input, you would think that someone would
seriously criticize a new design which had 16 optoisolators at a single
input, where each one is placed sequentially after the last. They would
say that you can't do that, it can only have one optoisolator at the
input. You could ask them why not 16 optoisolators all in a row? They
would answer that optoisolators, like all optical devices, have uneven
switching causing a rough output signal and it would badly distort the
signal to pointlessly go though 16 of them before getting to the CPU of
the MIDI slave. How hypocritical is this? That is exactly what happens
when you go MIDI in, MIDI through, MIDI in, MIDI through........again
and again to go through 16 of them, one for each channel! Maybe there
is some subliminal message in the spec, and exception to the rule, that
says only to use MIDI through three or four times in a row, unless you
have a lot of controller data, or perhaps only two times if you would
like your MIDI timing sync to remind you of the beat and feel you
started with... A joke, really. For this reason, do not use MIDI
through on an instrument, ever. To connect two MIDIJACK-equipped Moogs
to a sequencer, you might first take a look at the jack panel of the
sequencer. Does it only have one MIDI output? Sometimes a fancy
sequencer workstation has 2 or 4 MIDI outputs. If not, 18 years later,
it is time to finally step up to the plate and set up a proper
high-performance MIDI system. At worst, you could start with a small
MIDI through box and only connect all MIDI slaves to the output of that
to ensure that each one receives the exact same signal, rather than
differently delayed or distorted versions to each. For multiple MIDI
slaves, you should use the best, a MIDI patcher (or MIDI patchbay). In
the 80s, there were MIDI patchers from 360 Systems, Syncologic, KMX, JL
Cooper, and more. Who knows why they don't have them anymore? Why don't
they make Moog Sources anymore? These rack modules allow you to connect
a lot of MIDI inputs and outputs and route them via the control panel,
and storing complete MIDI setups in nonvolatile memory for recall
later. The 360 Systems 8x8 MIDI Patcher is probably the best. Another
one called a KMX MIDI Central is much fancier, but not as
straightforward. A simple glance at the 360, even from 15 feet away
onstage, will quickly tell you which input is connected to which
output. For best results, you should use one of these, they can now be
purchased used very cheaply. If you cannot do that and don't ever think
you'll need 8 or 16 outs, use a MIDI through box from Roland or
whatever. They typically have one MIDI in and four MIDI outs. They will
work, but are not not rack-mounted, etc. You can do it now or you can
do it later, but it is mandatory. A MIDI splitter cable is not possible
because MIDI is a data stream going through a current loop and is very
different from an audio or CV signal which could be split in many
cases. Question 35: Don't I just set a MIDIJACK-ed Moog to receive the track on a particular MIDI channel and set the MIDI sequencer to send on that same particular channel? Answer:
Exactly. It is simple that way. Up to 16 MIDIJACKs can be used in this
manner. Question 36: The MIDIJACK sounds great. My plan would be to house the unit in a stand alone box for use on various synths. Is this possible? Answer:
Sure, it would be possible, but it would defeat much of the purpose of
having it (convenience and selectability). It would work that way. The
warranty does not cover unintended usage. Synhouse has used several of
those for early beta testing. For daily usage, it is a lot of hassle to
patch it up each time. For studio use, okay, but for live, not a good
idea. The MIDIJACK was specifically designed for internal installation
and has many totally unique features that enable it to do what nothing
else can do. If it were intended for standalone usage, it would have
been designed much differently. In the reverse, an old MIDI control box
(such as a Roland MPU-101) cannot be removed from the original factory
enclosure and installed as a MIDIJACK can. Question 37: Can I use a MIDIJACK to hook up to my KORG X-911 guitar synth's CV input? Answer:
Yes, you can use the MIDIJACK II. It should be connected inside the
X-911, behind the jacks, so you can still use the CV/GATE jacks when
you need to just by turning the MIDI off. Question 38: Hello. I found your site via a post to one of the synth groups I read online. Your MIDIJACK looks very nice (and affordable). Is there any chance you have or are considering releasing a version with Hz/v scaling to accomodate these types of synths? A good deal of what I have is Hz/v and that would make these devices a little more enticing. Answer:
The MIDIJACK II: Hertz so good! was released 2/1/2001 and it is
specifically intended for Hz/v analog monosynths. Question 39: My keyboard is a Korg MS-10. Your site says the Korg MS-10/20/50 can use both the Original MIDIJACK and the MIDIJACK II: Hertz so good! How is this possible and which one should I choose for my own MS-10? Answer:
The Original MIDIJACK has a volt/octave output and the MIDIJACK II has
a Hz/volt output. The Korg MS-series are primarily Hz/v synths, but
they are unique in that they also have an adjustable volt/octave input
as well (labeled TOTAL or OCT/VOLT) so you have a choice as to which
one you'd like to use. If you use the Original MIDIJACK, you will have
the full MIDI 128-note range and the MIDI transpose select mode, but
you have to work within the limitations of the Korg's built-in
linear-to-exponential converter. This Korg circuit may take several
minutes to warm up to the temperature where it can be tuned and the
knob is extremely sensitive. Once tuned, it may drift over time as most
volt/octave synths do. This may be fine for studio use. If you use the
MIDIJACK II, you will then have a shorter MIDI note range and no MIDI
transpose select mode, but there will be several advantages which may
appeal to some users. 1) The tuning will be rock solid as Hz/volt
synths always are. 2) There will be no warm-up time. It will be ready
to go when it is first turned on. 3) Even the shorter MIDI note range
is a lot more than the Korg synths ever had without the MIDIJACK and
most users will find them to have the lowest bass lows and highs as
high as they need. 4) The installation is equally easy with either
MIDIJACK type, but the MIDIJACK II will go behind the Hz/v VCO inputs
and thus free up the v/octave inputs for external modulation or other
uses. All MIDIJACKs work very well. Question 40: I have a Korg MiniKorg II (also called the 700s). It does not have CV out ports on the case. Do I need a CV converter first before installing the MIDIJACK? Answer:
No, not at all. It will work with the MIDIJACK II: Hertz so good! There
is no point in putting an obsolete interface on a synth. Just solder
the MIDIJACK II wires to the CV and gate points inside the synth. If
you are uncomfortable doing the work based upon the three manuals it
comes with, you can send the synth to Synhouse L.A. and have the labor
done at the prevailing rates, and you pay round trip UPS costs. Question 41: Can I use a MIDIJACK for my Roland GR-700 guitar synth? It has MIDI but no MIDI input. Answer:
No. It isn't analog, it's digital. Question 42: Hi, my synth is a Micromoog. The synthesizer is in good working order, and the Synhouse MIDIJACK looks like a cost effective way for doing this but they say the Micromoog is the most difficult to mod. Answer:
No, actually, it does not say that. It says, "Beginners beware, the
conversion of a Micromoog to a MIDI sound module is one of the most
difficult MIDIJACK installations of all." What this really means is
that taking any keyboard synthesizer and chopping off the keyboard and
transforming it into a sound module is far and away more difficult than
installing the MIDIJACK in any synth. MIDIJACK installation is easy no
matter what the application is. If a Micromoog were already chopped and
reconfigured into a CV/gate sound module, it would actually be easier
to put a MIDIJACK on it than any other synth. The MIDIJACK has eight
wires to connect, but with there being no keyboard to bypass, you would
only need to solder four of them (+ power, ground, CV out, s-trig out)
and leave the others unused. Question 43: Has anyone tried this Moog Micromoog Module conversion? Answer:
Yes, the modification was performed by Synhouse and the article was
written. The most difficult thing was fixing a very broken Micromoog
with a dead VCO, the second most difficult thing was cutting it down
and reconfiguring it as a sound module. The addition of the Original MIDIJACK
was easy.
When it was done, it was cool-looking, sitting upright like a tiny
modular synth. Question 44: Okay, let's say to make things easier I only want to install the MIDIJACK without converting the Micromoog into a module. This would only require me to solder four wires? Do I need to do anything else like add a new resistor? Answer:
Yes, only four wires to solder and no resistors needed. Will the glide
function still work under MIDI control? Question 45: If it only takes soldering four wires I think I'm interested in buying a MIDIJACK for my Micromoog, please quote me the price plus shipping. I don't have a credit card so can I pay with a check or money order? Answer:
Yes, you can pay with a check or money order. The total is only the price of the MIDIJACK
because shipping is free worldwide. Question 46: Would CV/ S-Trigger jacks still work after installing the MIDIJACK? I may purchase an analog sequencer sometime in the near future. Answer:
Yes, as long as they work now. Another set of two problems: Question 47: I still haven't decided if I really want to buy the Original MIDIJACK for my Micromoog. I'm also looking into other options such as MIDI converters that would run around the same price range. Answer:
There are none from any reputable real companies for the price of a Synhouse MIDIJACK, unless you can find a used one.
Figure out the cost of a power supply and cables, two things that are
not needed with the MIDIJACK, you're going to need those, too,
and also add in the cost of shipping those items. While you are at it,
add up the cost of shipping "MIDI
converters" because, unlike the MIDIJACK, they don't have free shipping
worldwide. Question 48: Well, the jury is still out on the idea of spending money on a Synhouse MIDIJACK for my Micromoog because I want to be able to control modulation rate and note data via MIDI. Is there anything else I should know? Answer:
Quite a few things really, but most of them are well beyond the scope
of this Analog User Answer Forum... You cannot use MIDI to control the
modulation rate of your Micromoog with any product available from any
company. Question 49: Well, I still need MIDI for my Micromoog, but ****** (another company) claims to be able to control the glide and modulation on the Micromoog with their MIDI converter and no installation is required. What about that? Answer:
Please note that the Micromoog has a very good and special glide
circuit and LFO circuit, and there is no other device available from
any other company anywhere to control them as an internal retrofit. You
also cannot control those circuits via some external box because these
circuits are not externally voltage-controllable on a Micromoog (or any
other synth known to Synhouse). Look at the back panel of your
Micromoog and please notice that there are no jacks labeled GLIDE RATE
VOLTAGE IN or LFO RATE VOLTAGE IN. The Micromoog/Multimoog are
differentiated from the rest (Rogue/Minimoog/Source) by a very unique
and flexible modulation section with rate, source, and routing
controls. This has many sources such as ribbon controller and LFO
generating controllers that can be routed to many
destinations such as VCF and VCO. Nothing can do any of this
externally. Nothing can affect the routing selection, the sources, or
the destinations, as this would require a complete rewiring of each
section of the synth. Question 50: This is a problem for the MIDIJACK, but maybe I can still find some way to use MIDI to trigger the modulation input on the back of the Micromoog. Answer:
That is a problem that will continue throughout all time because the
Micromoog LFO rate cannot be externally voltage-controlled. See above
question 49 but consider the following: A lot of these devices from
other companies do have computer/digital/software-generated LFOs and
glide which can simulate those functions into their own voltages and
then go into the VCO and VCF jacks on synths, then those software-based
functions can be controlled via MIDI, if you have some way of remotely
generating those MIDI commands. Do you have a MIDI keyboard that will
send a MIDI LFO rate change command and a portamento rate change
command? Probably not. If you did, then you would be able to do
LFO/glide functions and remotely control them through MIDI, but they
will no longer be analog, and they will no longer be your Micromoog
with its' special modulation routing section and glide circuits, you
will simply turn the Micromoog glide off and the Micromoog LFO off.
Some users are satisfied with these software-simulated functions, but
some prefer real analog glide and modulation routing. You should ask
some experienced synth collectors or techs to refer you to a brand of
synth controller that will compensate for the .9v/octave problem that
the Micromoog has, to explain to you which functions can be externally
controlled and which can not, and to provide you with all the
custom-made cables you will need. The best thing to do would be to
learn more about your own needs and buy one of the top-of-the-line MIDI
converters which will control your Micromoog and any other synth as
well (Korg, Yamaha) all at once. They cost between $600-1,000, but are
well
worth the cost if you are serious and demand the ultimate in
flexibility. Question 51: Now I guess I'd still have the problem of not being able to control modulation rate via MIDI. Maybe it's best to leave the Micromoog as it is and control it with a MIDI controller, that way if something happens to it I can always sell it for parts and buy something like a Multimoog. Answer:
A wise choice. Question 52: Are the questions on the Synhouse FAQs page real? Answer:
No, these are not word-for-word verbatim quotations from actual
e-mails. All of them are rewritten with proper spelling and punctuation
and edited for clarity and legal reasons to remove the names or email
addresses of actual persons or companies so no liability can be
incurred for providing this information which could be helpful to other
Analog Users. Only about one in two hundred inquiries received are new questions
that aren't already answered clearly on this website and relevant
enough to be posted here. Some people who
write are so vague and daffy that it is impossible even to detect what
the problem and/or question is. An example would be the following
e-mail which is quoted verbatim except for asterisks (****) added for
privacy: Subject: help i just bought a
sh101 Question 53: I have a Korg MS-20 and a Micromoog. Will they work with your MIDIJACK? Answer:
They both have been tested and work with the Original MIDIJACK.
Additionally, the MS-20 may be used with the MIDIJACK II: Hertz so
good! Question 54: I was informed the you do in house installations. Is this true? Answer:
Yes. This service is available
now, with details and pricing on the Factory Installation page. Question 55: Will I lose any function of my analog synths when converted to MIDI with the MIDIJACK? Answer:
No, you don't lose anything. When the MIDI is turned off by pressing
the button for a half a second or more, the Original MIDIJACK
bypasses itself.
At that
time it acts as if it never had MIDI at all. When it is activated, it
gets note control on the selected MIDI channel, and the fastest MIDI
response available anywhere. Please read the functions listed on the
web page of the particular MIDIJACK model that concerns you and note
that it is a complete listing and does not have any other functions not
listed. Question 56: I think I read that you lose function of the mod wheel after installing a MIDIJACK. Is that correct? Answer:
Who knows where you read it. There is a ton of misinformation
on chat groups, etc, about the MIDIJACK and everything else in the
world. No, that is not correct. The synth is as it always was when MIDI
is off. When MIDI is off, you get all the stated functions. If you
mean, "Does the MIDIJACK receive MIDI mod. wheel?", then the answer is
no, it does not. You can tweak all the knobs, filter, modulation and
pitch wheel in real time while it plays from a MIDI sequencer, though.
Just notes on and off with a nice note buffer to make it play like a
real keyboard, trills and all. Additionally, MIDI sustain pedal is
received. If you need more functions, Synhouse recommends one of the
older brands such as the ones on the Synhouse links page, or Studio
Electronics or Lintronics. Those are generally regarded as being well
worth the $550-2,000 pricetag. The problem is that most Analog Users
cannot afford them, or would prefer to spend that money buying more
synthesizers instead of fancy modifications on things they already
bought, so those MIDI retrofits are rare for an obvious reason: They
don't sell very well. That is why Synhouse developed a simple,
reliable, easy to fit, $99 MIDI retrofit which has the fastest MIDI
response in the world. (Postnote 2010: The groundbreaking Original
MIDIJACK price of $99 was held for more than eight years, then finally
had to be raised in consideration of costs that had risen in each of
those eight years. Free shipping worldwide continues, for now...) Question 57: One quick question: Is it my assumption the MIDIJACK uses the standard one volt per octave scaling? Answer:
The MIDIJACK II: Hertz so good! is Hz/volt. The Original MIDIJACK is
shipped from the factory calibrated to exactly 1 volt per octave. When
you pull it
out of the wrapper it will give you 3.00v for MIDI note 36, 4.00v for
48,
5.00v for 60, 6.00v for 72, 7.00v for 84, 8.00v for 96, 9.00v for 108,
10.00v for 120, on up to 10.58v for the highest known MIDI note 127.
For an
easy test, the MIDIJACK has the automatic user calibration mode enabled
on
power-up, so it puts out the highest note 127 until you send it MIDI or
press
the button. The gate is off at this time so it will remain silent. You
can
check the voltage to see it is 10.58v and adjust it if it isn't. The
problem is that most analogs are out-of-whack now, just as they were
the day they were new.
The truth? People didn't use CV/gate control in the 70's, either. The
Micromoog sold thousands and no one ever noticed it was factory set to
.9v/octave and non-adjustable. Most older MIDI controllers cannot
compensate for that, but with the MIDIJACK, no problem, just turn down
the scale adjust trimmer. Question 58: How much can you vary the output of the Original MIDIJACK with the scale adjust trimmer? Answer:
A lot! You can turn it way down to around .25v/octave to control an EMS
Synthi or VCS-3 Putney, or way up to 1.2v/octave for an EML synth such
as the Electrocomp 101. This is a good design because most kids are
using beat-up analogs that are out of calibration, and won't pay to get
them calibrated either, not once, and not repeatedly as often as they
need to be serviced. You
can just twist the MIDIJACK trimmer and tune it right up. Also note
that the
keyboard and CV inputs are totally different circuits. ARPs and Moogs
and
everything else were tuned to their keyboards (a massive string of
matched
resistors between key switches) and not to the CV inputs. Companies
like
Switchcraft must have sold them millions of $$$ worth of jacks that
were used in
manufacturing but never plugged into anyway. Players like Gary Wright
used
CV/gate and remote keyboards, but their gear was always modified and
totally
custom and therefore they never needed the jacks to start with. Question 59: I'm interested in the MIDIJACK, though my inquiry is about the compatibility of it with Yamaha CS series analog synths. Specifically the CS5 monosynth. Will it work with this one? Answer:
Yes, it will work with the MIDIJACK II: Hertz so good! Question 60: I would like to MIDIfy my Synthi AKS. It has been my dream for many years. How do I install the MIDIJACK in this rather esoteric hybrid analogue/computer controlled beast? Answer:
Just buy the Original MIDIJACK, follow the instructions in the three
included manuals, and turn the scale adjust trimmer down. Question 61: As soon as your product supports the Odyssey, I'll buy it. Answer:
Too late. The Original MIDIJACK already supports the Odyssey, and it
has since July 2000. Question 62: I am the proud owner of a whitefaced ARP Odyssey and I'm considering to give it MIDI. However, since it's the earliest version of the Odyssey, and therefore very desireable of course, it has no CV-Gate interface at all. So I would like to know if it is possible to build the MIDIJACK into my ARP without having to modify it with CV-Gate-Trigger inputs first? I'm not really a tech, guess you've figured that out right away, but I think I could manage. I would need some good instructions though. Well, I just hope, that I don't need to do a mod first to mod my Odyssey. I guess you can understand that. Answer:
The Original MIDIJACK is definitely compatible. It does not need to
have CV/gate jacks, although it would be easier if it did, just because
it would be so easy as to not require any thinking at all. You just
need to locate the point in the synth where the keyboard voltage goes
to the VCOs, and break that point in the circuit and insert the blue
and white wires of the MIDIJACK, then find the point where the keyboard
gate signal goes into the envelope generator, break that and insert the
yellow and green wires of the MIDIJACK. There are three manuals
included which explain all theory and applications for any compatible
synth. It would be best not to add CV/gate jacks because it would be
foolish to drill several holes in the synth and spend all that time and
money to add an obsolete interface. Put a MIDIJACK on it and it will
still look clean and nearly original. Question 63: I would like to know about the availability of the MIDIJACK in The Netherlands. Where do I buy it? Answer:
If you are reading this for the first time, you are already here. The
Synhouse MIDIJACK is available worldwide. You can order securely online
in one minute on the ordering page of this website. Shipping is free
worldwide. They arrive in approximately 2-14 days, depending on where
in the world they are headed. Quite
simple, this. Question 64: Do you have instructions on connecting your MIDIJACK to an EML 101? Does it control all 4 VCO's or just VCO 1? I read about the scaling for the Micromoog and the suggestion that exponential oscillators like the EML and I suppose Paia are suppose to work. Aren't they Hz/Oct instead of V/Oct? So how does it work with Paia oscillators or EML? Answer:
The Original MIDIJACK is designed to be installed in most any analog
monosynth. There are no specific online instructions for the EML 101
because it is too rare to be feasible to document. The MIDIJACK
includes 3 manuals which describe how to install it in any compatible
synth. Below is a small quote from one of them: Question 65: Very interested in installing a MIDIJACK in my Korg Mono/Poly. Is this an acceptable synth to put it in? I would be in heaven if it worked!!!!! Answer:
The Original MIDIJACK does work with the Korg Mono/Poly. It is a
v/octave synth because it uses American SSM synth chips. Question 66: Can you tell me the power requirements of your MIDIJACK unit and its current draw? Answer:
The Original MIDIJACK comes with three manuals which provide
all the information
needed to install it in any compatible synthesizer. Quoting from one of
them, "For power, the MIDIJACK requires a regulated or unregulated
voltage of at least 12 volts DC but less than 30 volts DC, and any
analog synthesizer has such a voltage available for use. The MIDIJACK
current consumption is very low, approximately 30 mA." Question 67: Can the MIDIJACK be battery powered by strapping two 9 volt batteries together? This would allow it to be in a small box. I have a Serge modular but am not sure I have room in the box. Answer:
Yes, if they are connected in series. Two 9v batteries in series would
be a little over 18vdc, and it would work perfectly. Even better and
cheaper
in the long run would be to use one of those small rectangular battery
clips that hold 8 "AA" cells. Question 68: I have Casio CTK-550 with headphone/outlet and sustain. So the question is: Can I connect this CTK-550 with PC sound card (MIDI connector)? I can hear and record MIDI files from the net. Answer:
The question is not entirely clear. Maybe it would help to state a few
fast Original MIDIJACK facts: The MIDIJACK is for MIDI input
only. It can be
controlled by any MIDI device, including your PC sound card. The
MIDIJACK then puts out voltages to control an old analog monosynth
(ARP, Roland, Moog, Oberheim, etc...). Casio never made an analog
synth. With a MIDIJACK and a real analog synth you can play MIDI song
files from the internet. Question 69: I have
some analog synths. They are : Answer:
No. Question 70: Hello, I have a Micromoog and I am considering purchasing a MIDIJACK to control it. I do not want to destroy the synth as per the modification article featured on your site. Is it possible to install the MIDIJACK into this synth while still retaining the normal functions of the ribbon controller, mod wheel, and keyboard when in non-MIDI mode? Answer:
The Original MIDIJACK includes free shipping worldwide and three
manuals which provide all the information necessary to install it in
any compatible synthesizer. The articles on the website are just notes
from installations actually done by Synhouse and are only about .01% of
the total possibilities. If you followed the article and just
remembered not to saw off the keyboard, you'd be fine, and MIDI would
be defeatable with the button, returning the Micromoog to normal
non-MIDI use. Question 71: Will the Original MIDIJACK work for my Kawai SX-210? Answer:
The Original MIDIJACK is specifically designed for monophonic analog
synths and will not work for your synth because the Kawai SX-210 is
neither monophonic nor analog. Question 72: Can I use the Original MIDIJACK on my Crumar Stratus? It is not monophonic. Answer:
The Original MIDIJACK probably will not work for you, although nothing
is really known about the Stratus because Synhouse has not researched
the compatibility. The Original MIDIJACK is designed specifically to
add MIDI to real voltage-controlled analog monosynths. Fake polyphonic
synths (like the ARP Omni, String Ensemble, Roland Saturn, Moog Opus 3,
Polymoog) will not work because they are polyphonic and the Original
MIDIJACK is monophonic and they also are not really voltage-controlled
analog, but rather more like a home organ. Your Stratus may be of this
type. Another type of synth would be the real analog oscillator
polyphonic synth like the Prophet-5, OBX-A, or Memorymoog, which can
use the Original MIDIJACK, but it would be pointless as it would only
control one voice. Question 73: Hello, is it possible to midify a Roland TR-606 with your Original MIDIJACK? Will the velocity of the drumtones be adjustable via MIDI or will all the tones have the same velocity? Answer:
No. The Original MIDIJACK is specially designed for analog
monosynths.
As for what you are looking for, there is no such internal MIDI
retrofit available from any company in the world. The TR-606 is not
MIDI and it does not have velocity without MIDI anyway. The only brand
of analog MIDI retrofit small enough to fit inside a TB-303, MC-202, or
TR-606 is Synhouse, but it is not intended for drum machines. Question 74: Will the Original MIDIJACK work with a Roland SH-101? Answer:
Yes, it works very well. Question 75: I'd like to install an Original MIDIJACK into my Elka Synthex first edition. Is this possible? Answer:
The Original MIDIJACK is specifically designed for monophonic analog
synths and will not work for your synth because the Elka Synthex is
neither monophonic nor analog. Question 76: Hello! I've got one query: Will the MIDIJACK work with the Minimoog? If so, will it have fitting guide included? How about ARP Odyssey? Will it go well with Hz/v synths? MS-20 in particular. Answer:
The Original MIDIJACK will work with the Minimoog, Odyssey, and MS-20,
and the MIDIJACK II will work with the MS-20 and all other Hz/v synths.
Full installation instructions are included. Question 77: Hello. I'd like to order a MIDIJACK. From the website it looks as if it can be installed in a MG-1 synth. How about Moog Sonic Six or Minimoog? Answer:
Yes, the Original MIDIJACK it will work with the Minimoog and Sonic
Six. It will work with the Sonic 2 and Sonic 5 as well. Question 78: I would like to install your MIDIJACK in my Oberheim Two-Voice. Trouble is, I don't find the Two-Voice among the synths you provide installation instructions for on your Analog User Modifications page. Do you know whether the MIDIJACK can be installed in the Two-Voice so that the user can drive both SEM modules from either the keyboard or MIDI? Answer: Just to be clear, the Original MIDIJACK is for analog monosynths. It is not polyphonic. It will certainly work very well in an SEM, although Synhouse has not done one hands-on yet or written an article. There probably won't be an article for that one, as it is too rare. There needs to be more information provided about the instructions. A lot of e-mail requests are received where people say, "I want to buy a MIDIJACK, but only when you have an article for my Octave Kitten. When will it be online?" Well, the truth is, the three manuals provided free with the MIDIJACK contain 100% of the information needed to put it an ANY compatible synth, but the installer must read them first. We can't justify spending 20 hours and $500 writing a specific synth article to secure a single $99 sale. The information on the Usermod page is just some extra free info for some extremely common and affordable synths. It expedites the installation. Until Synhouse came along, no one had ever provided any free online do-it-yourself photos and plans for such a product, so it would seem that Synhouse is way ahead in generosity there. (Postnote 2010: The groundbreaking Original MIDIJACK price of $99 was held for more than eight years, then finally had to be raised in consideration of costs that had risen in each of those eight years. Free shipping worldwide continues, for now...) If you wish to pursue this
Two-Voice job, you must make a few decisions: 1) Will it control only one SEM? Question 79: I have a question concerning the MIDIJACK interface. I'm thinking of installing MIDI on my Yamaha CS15, Korg MS-20, and Mono/Poly. Does your MIDI kit work for those synthesizers? Answer:
Yes. Actually, it is not a kit with parts and a circuit board. It is
fully assembled and tested and the wires are prepped and ready to
connect. The Original MIDIJACK will work for the Korg Mono/Poly and the
Korg MS-20, and the MIDIJACK II: Hertz so good! will work for the Korg
MS-20 and Yamaha CS15. Question 80: I just purchased a Paia 4700 modular synth and need to retrofit it to be compatible with MIDI. Its' triggering method differs from most analog synths in that it is not control voltage controlled. Instead it uses linear-response (V/Hz) the same as the Korg MS synths. I am curious as to whether the MIDIJACK would be compatible with my synth. Answer:
Your question itself is a little incorrect. The Paia 4700 is a
voltage-controlled synth. It does have linear VCOs that require an
exponential type of input (such as provided by the MIDIJACK II: Hertz
so good!). The Korg MS-series is not limited to strictly Hz/volt,
either. The MS-10/20/50 can accept either a volt/octave or Hz/volt
control voltage (so they can use either the Original MIDIJACK or the
MIDIJACK II). For a Paia 4700, you would use a MIDIJACK II: Hertz so
good! Question 81: I would like to know if the MIDIJACK is compatible with a Korg MS-20. If it is, how much is shipping to Perú? Answer:
You can use either the Original MIDIJACK or the MIDIJACK II with the
Korg MS-20. Shipping to Perú is free. Question 82: I have a Realistic MG-1 and am very interested in a MIDI mod. How much do you sell the Original MIDIJACK product for? I also have a Rhodes VK 1000 which is 77 key. Will all of the keys work on the MG-1 after the mod? Answer: Current pricing for the Original MIDIJACK is on the ordering page. Shipping is free worldwide. Pricing for Synhouse
Factory Installations are on the Factory Installation page. The keys on the MG-1 will still work when
the MIDI is off and it will receive all 128 MIDI notes when the MIDI is
on. Question 83: Hello, I was wondering if the MIDIJACK is compatable with the Korg MS-20? If so, please let me know, because I'm debating on selling it, but if I could MIDI it up for the price of a MIDIJACK, I'd definitely hold onto it! Answer:
Yes, the MS-20 will work with either the Original MIDIJACK or the
MIDIJACK II: Hertz so good! Please see the answer to question 39
above. Question 84: I have a Roland MC-202 at my home, and maybe I want to midify it, it's possible with your MIDIJACK system? Answer:
Yes, it works with the Original MIDIJACK. Question 85: I bought an Original MIDIJACK for my Roland TB-303 and I'd like to know once this piece is installed what sort of control do I have over the 303 I'm going to install it to? Tempo? Notes? Tracks? Patterns? Etc? What can I do with the chip that I couldn't already do with the 303? One question before I continue will the 303 sync to the keyboard after it is all connected? Can you send me a list of e-mails of people who have installed the chip into the 303 and playing with it now? The reason I ordered the piece is to sync the 303 to my keyboard (Korg Triton), I have been using the 303 in many of my tracks, but all the cannot be recorded unless I get a way to sync the 303 with the rest of the performance. I tried numerous times in getting the Roland Sync Box SBX-80 but never succeeded. I found your site and I thought, my search is over. The simplest piece of equipment to do the job. I wanted to send it Devil Fish but I never came around the money to do so. My question is can I control the tempo of the 303 from my keyboard? If I cannot sync the 303 with my keyboard with your device I'm sorry but I will have to return it. Answer:
This is not completely clear. You are asking many questions but want
only one answer. There are many answers. Here are a few facts which may
answer some or all of your questions: Question 86: Why don't you sell the MIDIJACK as a kit? That's what I want, a kit version, because I know how to solder and I'd like to save some money. Answer:
This question comes often. Can a question be best answered with a
question? Why doesn't Sony sell their DVD players as kits? Why doesn't
HP sell their printers as kits? Why doesn't Casio sell their watches as
kits? Because they are machine-manufactured on a robotic assembly line
with carefully controlled processes. The temperatures, humidity levels,
and cleanliness are critical. The MIDIJACK is just the same. It
couldn't be soldered together at home by a musician no matter how often
people dream that it could be. The high-speed data circuitry requires a
board that is cleaner than one could make at home. It has unbeatable
combination of price, performance, and convenience that could not be
duplicated by a kit from this company or any other company. It would
actually cost more to sell it as a kit due to the high-volume custom
surface-mount componentry used. It is assembled by robots and no person
touches any of the resistors, capacitors, or integrated circuits at any
time before, during, or after the multistage soldering processes. They
have not even been viewed by the human eye prior to final inspection. A
bigger issue is wasting tech support troubleshooting nearly a thousand
user-assembled kits each year. How much would that cost? Sure, the
MIDIJACK could be redesigned to use different components and be four
times the size to enable hand-soldering, but why? Question 87: I came across the Original MIDIJACK and would like to try it on my Pro-One here, I live in Holland, do you have distribution here? Answer:
You can order it securely online and it will be shipped to Holland for
free. You will get it in a few days. Question 88: I am having a problem with the Original MIDIJACK in my Moog MG-1. When I adjusted the trimmer on the MIDIJACK board, so the MG-1 would play a complete scale I forgot to check if it was in tune with anything else. I'm realizing now that when I tune the low C to actual C, via the MIDIJACK, the keyboard doesn't run through the scale, basically right about E it starts to go off scale and by the time I get to the next C it's totally off. I've checked the tuning pot on the MG-1 and that's not the problem, so I'm wondering what it might be. Any suggestions? Answer:
Yes, set the Original MIDIJACK scale adjust trimmer back to the way it
was when you received it from Synhouse, which is in tune. You never
tune the MIDIJACK, you adjust the scaling, which means that turning the
trimmer up stretches the tuning between the keys, the intonation, not
the tuning. The MIDIJACK tuning is always the same, where MIDI note #0
is a very
accurate 0 volts. When set to around 10.58v during calibration mode (a
software-simulated MIDI note 127), you are at exactly one volt per
octave, and
MIDI note #12 is 1v, #24 is 2v, #36 is 3v, and so forth. If you are
using
something which claims to be 1v per octave but is actually not, like a
Micromoog, it will want to get about .9v per octave, and this is no
problem for
the MIDIJACK. You turn it down and would get 0v, .9v, 1.8v, 2.7v, and
so
forth. Systems which try to do this in software really fall apart here
in their
resolution, because analog is infinite. You TUNE to another reference
with your
master tuning control on your synth. Match a low one by synth tuning ,
then
trim the MIDIJACK scaling so the high notes also are in tune. Question 89: Does the Synhouse MIDIJACK provide MIDI out as well so I can use my Pro-One as a MIDI master controller? Answer:
No, fortunately. A Pro-One? You couldn't find a worse master controller
keyboard if you tried. It is incapable of controlling itself reliably,
so there is no point in using MIDI to share that misfortune with other
synths. There were two revisions of the Pro-One keyboard mechanism.
There was one that was horribly unreliable and there was another one
that was worse. Question 90: I have an OB-1 and an ARP Axxe that I would love to retrofit. Would the MIDIJACK work? Answer:
Yes, the Original MIDIJACK will work for both. Question 91: I went to order a MIDIJACK from your website but I didn't feel good about your online ordering system. I don't trust having my credit card number accessible on the internet. Can I pay by some other method? Please reply. Thanks. Answer: Yes, it is
possible to mail a money order or check as stated on the ordering page,
unless you are still on the gold standard, in which case you will need
to update to contemporary currencies. Unfortunately, you will have to
trust the government enough to use US dollars. Seriously, the
Synhouse.com e-commerce facility is the most secure available today.
Proprietary software is used to accept your card online with 40-bit
encryption and the information is transferred offline with 128-bit
encryption. The card number is held only in RAM, not on a network
server, and is held by Synhouse offline and is never accessible online
via Synhouse.com after that. This is interesting, because all the
credit cards that you do not want to make accessible online are
actually accessible online 24 hours a day already. The next time you
receive a credit card statement, look at the extra printing on the bill
that asks you to try reading your statement and paying your bill online
at the website of the credit card company, such as Americanexpress.com
or MBNAnetaccess.com. You can go there, sign up, log in, and manage
your account online. Therefore, your credit card is already accessible
via the internet, whether or not you approve of or choose to
participate in the e-commerce revolution which has migrated a great
portion of all worldwide commerce to the internet. Ask the FBI if
hackers from Seattle to the Ukraine are trying to hack into banks and
credit card companies every day. Once they tell you yes, you will
realize that it is false security to add a few weeks' delay your
MIDIJACK order by mailing a check or money order. E-commerce has become
successful primarily because it is quick and convenient. Synhouse
receives more than 99% of all sales revenue via the internet. Question 92: Hi. I have an old Wurlitzer Stage Piano that has awesome feel. I'll never find a controller I like as much as this Wurli. Would it be possible to use your MidiJack to make the Wurli into a MIDI master keyboard? Answer:
The Original MIDIJACK is for analog monosynths only. It is both analog
and monophonic, so it does not work for upright pianos, grand pianos,
Rhodes pianos, Wurlitzer pianos, Hammond organs, string machines, or
anything other than analog monosynths.
Answer:
The MIDIJACK II was designed to be compatible with the original
Taurus (I) pedals. They have been done at least a few times by
customers and one time here as a Factory Installation. Copyright ©
