VCMC is a Voltage Controlled MIDI Controller, a fully mapable MIDI device with eight Faders and Buttons. ach
of those controls has a CV and a Gate Input associated either to automate their functioning or to be
configured independently for further control.
very setting on VCMC can be edited through its OL D screen and will be output either via DIN5 or USB as
Class Compilant MIDI Device.

There are two main MIDI connections in VCMC: USB and DIN5. Both connections send every MIDI
message generated by the module, choosing each one depending on the device you will be
controlling. Let's take a deeper look:
USB
The USB port is the most convenient way to connect VCMC to a
computer. Just plug a USB Type B cable from VCMC to a free USB port of
your computer and the module should be automatically recognized as a
MIDI Device. You will be able to select it on the MIDI connections of your
DAW or any other software that supports MIDI.
If you have USB Host devices, you can use this port with it in the same
way we did with the computer.
DI N 5
Most of the external gear out there uses DIN5 connections for MIDI
control. If you want to control your external gear with VCMC, just plug a
standard MIDI DIN cable from VCMC´s DIN5 Out port to your device´s
MIDI Input.

S T R U C T U R B L O C K S & P R F O R M A N C S C R N
In VCMC, you have a variety of
different controls and connections
capable of sending MIDI to your
external gear. To make it as clear and
friendly as possible, the module is
divided in eight functional blocks.
A block is conformed by a set of
controls that can be configured to
send different MIDI messages.
Basically, each block contains a CV
Input, a Fader and a Gate Input with
a linked Push Button.
The activity of each block is displayed
on the Performance Screen.
The Performance Screen is the
main level of the VCMC menu
structure. Here you can
navigate trough the different
blocks, rotating the encoder, to
check their activity.
On the left of the screen, you
will see the values sent by the
CV Input and Fader of the
current block and, if both are
linked, the value of the link.
On the right part, you have
overall real time information
about the values sent by every
VCMC block.
Performance Screen
VCMC Block
Besides its eight functional blocks, VCMC includes two Auxiliar
inputs. The behaviour of those inputs is exactly the same as the
block CV inputs and their activity is displayed on the Performance
Screen as well.

Click the encoder on a selected block to configure it.
In this menu you can navigate through the different controls of the selected block. Access them
by clicking the encoder button. For each control you will be able to map MIDI Messages, MIDI
Channel and input and output ranges.

Buttons can be mapped to send a MIDI message when pressed. This message can be either a Note
or a value of certain CC. They can be configured as Gate, where value will be present while
pressed, or latch where the value will remain on when pressed and turn off when pressed again.
Other messages that can be mapped are clock or ST/SP.
Gates are associated to Buttons by hardware, so a gate present here will be added to the value of
the button and viceversa. The L D will show us any activity.
FAD RS
Faders will be sending a midi message with value proportional to the fader position.
It can be set up as an independent, or associated to the CV input to be added, or as an
attenuator.
CV
ach CV input will be sending a MIDI message with value proportional to the voltage received.
It can be set up as independent or associated to the fader to be added or attenuated, or to the
Gate for the V/Oct to MIDI note mode.
AU X
These are two auxiliar inputs. They can be mappedr to MIDI messages, similar to inputs, but they
do not accept negative voltages.
On the left column of the
Configuration Screen you
have the information
section. It displays the
MIDI Messages assigned to
each control.

ach VCMC control has its own configuration menu where you
can configure its behaviour. Let's start with the CV Inputs.
From the Performance Screen, select a block and press the
encoder to enter into the main Configuration Screen. Go to CV
and press the encoder again to enter into the CV dit Menu.
On the left of the screen there is information about the selected
MIDI channel and the current Function of the CV Input.
At the right you have the following options:
FU N CTI ON
Selects the MIDI message that will be mapped to this input. By pressing on it you will have access
to the MIDI Mapping screen.
1. V/Oct t N te
In this mode Gate and CV will be linked so we can convert CV + Gate messages to MIDI notes. When Gate goes
high, a NOT ON message will be sent with value proportional to the CV input. When Gate goes down a Note
OFF message will be sent. Keep in mind that, in order to keep V/Oct range, only 120 MIDI notes will be sent
for the whole range. 1 Octave=12 semitones, so 10 Octaves 120 notes.

2. N tes
On this mode the module will generate MIDI notes at the selected MIDI Channel following the V/Oct ratio
regardless of the presence of Gate or not. The Gate lenght is fixed.
3. CC
This will send CC messages. When selected you will be prompted to choose which CC number will be sent.
4. Vel city
CV will be mapped to velocity message representing the notes selected in the MIDI
channel.
5. Pitch Bend
CV will be mapped to pitch bend message.
6. Pr gram Change
A program change message will be sent proportional to CV value.
TIP: Program change will change the program in the current bank selected in your Machine. Map CC#0 or
CC#32 in another input to do a bank select and double the fun!!
7. NRPN
In this mode the CV will be converted to NRPN messages. Upon selection of this mode you will be prompted to
select a NRPN number. Keep in mind there are two NRPN modes available: 7 bit and 14 bit.

CV D LAY
Set a delay on the CV reading. Specially useful on V/Oct mode. As some sequencers have some
delay between setting the gate high and sending the CV, with this feature you will avoid sending
old messages.
R AN G S
On this screen we will be able to set the functional ranges of the CV Input and the MIDI Output.
Here you will be able to calibrate the CV Input as well. Let's take a look:
1. In Range
+10: The CV Input will expect a voltage range of 0-10V, translating each voltage in concrete MIDI value.
A voltage of 1 0V will be translated as the maximum MIDI message value (see OUT Range below)
+5: The CV Input will expect a voltage range of 0-5V, translating each voltage in concrete MIDI value.
A voltage of 5V will be translated as the maximum MIDI message value (see OUT Range below)
-5/+5: The CV Input will process negative voltages as well. In this mode a voltage of 5V will be
translated as a MIDI value of 64 and -5V to -64, Negative values will be clipped to 0, so linking the fader
as SUM (see CV/FDR Link) is adviced for effectivity.
2. Out Range
MIDI ANGE: Select from what MIDI value to which one your CV will
be scaled. This feature will select the minimum and maximum MIDI
values and will scale the input to that range.
MIDI T IM: With these you can set MIDI limits, so no messages will
be sent beyond the minimum and maximum set here. This feature
clips the range, do not scale.
3. Calibrati n
This will perform a two points callibration. You will be
prompted to send 1 v and 4v, stating to which MIDI Note they
relate to. A voltmeter is shown to monitor incoming voltage.
This calibration is useful when your CV source has some
offset, so you can avoid note shifting on conversion. Also, if
source CV does not have perfect V/Oct linearity, this will
correct the scaling.
Set the values of each range by turning and pressing the encoder. If you don't want to keep the
changes and go back to the previous screen, press Cancel, otherwise press nd.
CALIB ATION P OCEDU E: Before selecting calibration, be sure you have V/Oct to Note mode selected on
the CV Input you want to calibrate, otherwise you will get an error message prompting to activate it.
Once done, plug the CV signal from your sequencer or CV source, set it to send 1V (go to the manual of your
CV source if you don't know the equivalent Note/Volts) and check the voltmeter at the bottom of the screen. If
all is well it should show you C0/1V, then turn the encoder till you have the first line (1V 24 C0) selected and
press the encoder. Repeat the process for 4V and press nd to finish the calibration. If you don't want to keep
the changes, press Cancel.

In VCMC, the Faders can take multiple functions. One of the most interesting of these, is to link
them with the block CV Input. With it, you can use the Fader as, for example, an attenuator of
the signal present at the CV Input. Let's take a look.
- INDEP: The Fader has its own function and is not linked to the CV
Input (Default behaviour)
- SUM: The value of the Fader is summed with the value of the CV
Input. On this mode the Fader works as an offset control for the
incoming signal.
- ATTE: The Fader acts as attenuator of the incoming signal at the CV
Input.

By default, VCMC comes with an initial setting that allows you to quickly test some of the
features of the module. In this configuration, push buttons have assigned C Major scale notes ,
starting with C3 (Note 60) in Block 1 button and finishing with C4 (Note 72) in Block 8 . CV
Inputs and Faders are assigned to CC's. Being Faders CC numbers from 1 4 to 22 and CV
Inputs CC numbers from 23 to 30. AuxA is assigned to CC 31 and AuxB to CC32.

In VCMC, you can save and load configuration presets externally via SYS X (System xclusive
Messages). This process can be done with a lot of applications (like DAWs or specific MIDI apps)
and if you have vintage digital gear for sure those terms won't be new for you.
If this is not the case, don't worry, we're gonna explain a very easy and fast way using MIDI OX.
LOADI N G PR S TS
Launch MIDI OX and in the top bar press "Options >> MIDI Devices..." Select VCMC on MIDI Outputs
and press OK.
Now go to "View >> Sys x..." On tihe new window (Sys x View & Scratchpad) press "File >> Send
Sys x File..." Select your Sys x file and press Open. As soon as the status bar finishes, you will
have a prompted screen on your VCMC. Press Load Sys x, select the bank, press Discard and you
are done.
SAVI N G PR S TS
MIDI OX is a free program for Windows (and Linux through Wine-HQ) that is able to play
*mid/*syx files and upload them into VCMC. First connect your VCMC to your PC via USB
connector (Type B to Type A USB cable). Launch MIDI OX and in the top bar press "Options >> MIDI
Devices..." Select VCMC on MIDI Inputs and press OK.
Now go to "View >> Sys x..." On the new window (Sys x View & Scratchpad) press "Sys x >>
Receive Manual Dump..." The program will start to wait for Sys x messages. Once done, go to the
Global Settings Screen on your VCMC (hold the encoder for 2 seconds on Performance Screen) and
selects Save Conf. selects the bank and now check MIDI OX again. If all is fine you will have a
message on MIDI OX with the size of the file received, press Done. Now go to "Display Window >>
Save As..." Put a name to your file, save it in your preferred folder and that's all.
