VCMC is a Voltage Controlled MIDI Controller, a fully mapable MIDI device with eight Faders and Buttons. Each
of those controls has a CV and a Gate Input associated either to automate their functioning or to be configured
independently for further control. Every setting on VCMC can be edited through its OLED 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.
DIN5
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.
B A S I C
S T R U C T U R E B L O C K S & P E R F O R M A N C E S C R E E 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.
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.
As pictured, the available controls to configure are as follow: 1. CV
Configure CV Input
2. Fader
Configure Fader
3. Gate
Configure Gate Input
4. CV-FDR-Link
Select CV-Fader Link mode:
Sum or Attenuation.
5. Chord Mode
Configure Chord options
Keep in mind that some of these options will disapear, depending on the choosen mode. We will
cover this further ahead in the manual.
Scale and chord options will be visible only when a note mode is configured in the block (either
CV, Fader or Gate). Keep in mind these scale and chord options will affect ANY note mode
configured. Plese refer to Chord Mode section for further details.
S E T T I N G T H E
B L O C K S C O N T R O L S O V E R V I E W
BUTTONS/GATES
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, ST/SP or Panic.
Gates are associated to Buttons by hardware, so a gate present here will be added to the value of
the button and viceversa. The LED will show any activity.
FADERS
Faders will be sending a MIDI message with value proportional to the fader position.
It can be set up as an independent control, or associated to the CV input, either to be added, or as
an attenuator.
CV
Each 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, as well as to
the Gate for the V/Oct to MIDI note mode.
AUX
These are two auxiliar inputs. They can be mapped 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.

Each 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 Edit Menu.
FUNCTION
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. CC
This will send CC messages. When selected you will be prompted to choose which CC number will be sent.
2. V/Oct to Note
In this mode Gate and CV will be linked so we can convert CV + Gate messages to MIDI notes. When Gate goes
high, a NOTE ON message will be sent with value proportional to the CV input. When Gate goes down a Note
OFF message will be sent. Keep that in mind, 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.
FOR EVERY NOTE REPRESENTATION IN VCMC WE ARE ASSUMING THAT MIDI NOTE 0 IS C-2
When a note mode is selected new scale and chord options are available. Please refer to page 11 for further
information about this mode.
3. V/Oct Poly
With this mode you can send several notes with one gate. On selection, Gate 8 will be automatically set as the
gate to send a note per channel configured like this. No need to manually configure this gate. If you send
several CVs as V/Oc Poly, gate 8 will send a midi note per CV configured.
When a note mode is selected new scale and chord options are available. Please refer to page 11 for further
information about this mode.
4. Notes
On this mode the module will generate MIDI notes at the selected MIDI Channel following the V/Oct ratio
regardless of the presence of a Gate. The Note duration is set right after selecting the mode, so you can set a
few fixed durations, edit yours or select that the Note off is sent just before sending a new note:
No auto OFF, 500ms, 1000ms, 1500ms, 3000ms, Edit AutoOff
5. Velocity
CV will be mapped to velocity message representing the notes selected in the MIDI
channel.
6. Pitch Bend
CV will be mapped to pitch bend message.
7. Program Change
A program change message will be sent proportional to CV value.

V C M C C O N F I G U R I N G V C M CU S E R M A N U A L
.6
MIDI CHANNEL
Selects MIDI Channel for this CV Input.
CV DELAY
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, that gives the wrong impression of out of tune notes being sent.
Default CV Delay is 3ms.
RANGES
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 10V 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.
8. Channel Pressure
With this option CV /Fader will be converted to Channel Pressure message, also known as channel aftertouch.
This message will affect to all notes that are received in that MIDI channel. Upon receiving Channel Pressure,
it's up to the device how it will respond to this message (VCA, VCF cutoff or even LFO rate for vibratos)
9. Digital Functions
You can select Digital Functions, same as Gate Inputs (Check Page 8)
10. Chord Functions
In this sub-menu you will find options to control chord parameters. When you select one of the options, you
will be prompted to select a bank. If you selected a Note mode in that bank, the CV will affect to any chord
generated in that bank.
* Scale
* Root SCALE
* Chord type
* Chord Voicing

11. High Resolution MIDI
CC 14 Bits
With this mode VCMC will send a 14 bit CC message. This message will be sent as two CC mesages.
Higher 7 bits will be sent on selected CC and lower 7 bits will be 32 values higher. Ex. If you select 14
bit CC#2, Higher bits will be sent first on CC#2 then Lower bits on CC#34.
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.

2. Out Range
MIDI RANGE: Select from what value your CV will be scaled. This
feature will select the minimum and maximum values and will scale
the input to that range.
Value range might change depending on the funtion selected.
MIDI TRIM: 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, not scales it.
3. Calibration
This will perform a two points callibration. You will be
prompted to send 2v and 8v, stating to which MIDI Note they
relate to. A voltmeter is shown to monitor incoming voltage.
If you have selected 5v input range, voltages will be 1v and
4 v. 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 End.
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 End to finish the calibration. If you don't want to keep
the changes, press Cancel.
PORT NAME
You can label every port to help identify the mappings you have made. The label choosen will be shown in
performance screen, close to the MIDI value it is sending. In this menu you can choose between a list of
common labels and edit a set of user defined labels. Then a sufix can be added to identify a parameter used
multiple times (PAN1, PAN2, etc...)
1. Select Name
Select name for the port between the list of predefined labels and User defined labels.
2. Sufix
Set a sufix for the port.
3. Edit User Defined
There are 15 available slots for user defined labels. Scroll down to select a slot and click encoder to edit that
label. Scroll through the characters with the encoder and selects it by clicking it. To end editing just finish
inserting characters in the line.

SCALE MODE
With this option you can select the scale you want your CV to be quantized to. If the CV does not match a note
from selected scale it will send the previous lowest note that is present in that scale.
Available scales are:
Lydian, Major/Ionian, Mixolydian, Dorian, Minor and Phrygian.
CHORD TYPE
This will select the kind of chords you will be sending. Keep in mind that if you selected a scale,
then the type of Chords are pre-configured as per each scale.
When a scale is selected you can choose:
When selecting the scale you will be automatically promted to select the tonality of the scale. You can
select Full scale, that will send all notes, meaning there is no quantization.
ROOT SCALE
Select the tonality of the scale.
* No Chord: Send one note
* Diatonic Triad: Three notes Chord
* Diatonic Triad +7th: Four Notes chord with 7th
CHORD VOICING
With this option you can select Inversions, open chords and
Drop voicings. These will move certain notes within the chord,
providing some extra flexibility.
A drop voicing is created by dropping one of the notes down
an octave. If the second note from the top is dropped, the
voicing is called a drop 2 voicing; if the third note from the
top is dropped, the voicing is called a drop 3 voicing.
Open chords are made like drops but moving the notes up one
octave instead of down.
Chord Inversions are chords that don't have their root note as
the lowest note. So each inversion is made bringing the notes
down one octave and keeping the root.
So you have for four notes chords, Drop3, Drop2, Inversions,
Open2 and Open3. Each with the root chord and the three
inversions. Having the closed chord in the center and opening
the notes in both directions.

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. Faders are CC numbers from 23 to 30 and CV Inputs CC numbers
from 14 to 21. AuxA is assigned to CC 32 and AuxB to CC33.

stuck or held.
In Performance Screen, hold the encoder for 5 seconds to access the Global Settings. On this screen you will be
able to save and load presets between other things. Let's take a look.
GLOBAL C V CAL
Calibrates all CV Inputs at the same time. Quite useful when you
have a multichannel CV Source (like a sequencer).
SAVE CONFIGURATION
Saves the current configuration of the module in one of the four banks available. At the same time
the module saves the setting on its internal memory, a SYSEX message is sent via MIDI Outputs
(see SYSEX paragraph below).
LOAD CONFIGURATION
You can choose either one of the settings saved on the two user banks or a factory preset (Go to
Apendix 1 for further details).
FACTORY RESET
Restarts the module to initial factory settings (see Out of the Box Configuration).

In VCMC, you can save and load configuration presets externally via SYSEX (System Exclusive
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, or our web editor.
LOADING PRESETS
Launch MIDI OX and in the top bar press "Options >> MIDI Devices..." Select VCMC on MIDI Outputs
and press OK.
Now go to "View >> SysEx..." On tihe new window (SysEx View & Scratchpad) press "File >> Send
SysEx File..." Select your SysEx file and press Open. As soon as the status bar finishes, you will
have a prompted screen on your VCMC. Press Load SysEx, select the bank, press Discard and you
are done.
SAVING PRESETS
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 (USB
B to USB A 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 >> SysEx..." On the new window (SysEx View & Scratchpad) press "SysEx >>
Receive Manual Dump..." The program will wait for SysEx messages. Once done, go to the Global
Settings Screen on your VCMC (hold the encoder for 2 seconds on Performance Screen) and select
Save Conf. Select 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..."
Name your file, save it in your preferred folder, and that's all.
FIRMWARE UPDATE PROCEDURE
1: Get latest firmware file from Hex folder in our github. Make sure you
clone the repository, as downloading just the file won't work.

This module is the result of loads of hours of work, love and care. It
would have been imposible to finish without the help of beta testers,
loving friends, people from Hangar's open thursdays providing very
strong opinions and the whole Befaco team kicking asses as usual.
Hardware design, testing, documentation, graphic user interface and
many funky extra features: Befaco team.
Caring, relentless, tireless beta testers: Miguel Cruz, Jose A. Cabrera,
Miguel Eedl, Luis Bot, Ben Wilson aka Divkid and Ziv Eliraz aka
Loopop and Quincas Moreira aka Synth DIY guy.
Thanks to Tony Fleigh for Chords mode idea and initial code!
Firmware coding, common sense and über-cold beers:
