AUX CV:
This analog output can be set to put out one of three different things using the 3-‐position
switch:
•
(V) Velocity of last priority MIDI note received (0 to +5V)
•
(M) Mod wheel position (0 to +5V)
•
(A) Aftertouch (0 to +5V)
MIDI IN:
Connect a MIDI signal from anything with a standard DIN MIDI output jack to this input. Data
received will be looped through to both the USB and MIDI OUT connectors. It will also drive the CLK,
AUX, CV and GATE OUTs where applicable (see sections on those outputs for more details).
MIDI OUT:
This output acts as a MIDI THRU, repeating MIDI data received on both the USB and MIDI IN
ports.
If data is being received on both those ports, it gets merged before being sent to the MIDI OUT (and
USB) port. The merging is done intelligently, so that running status is taken into account (and stripped),
SysEx messages are kept together, etc.
The MIDI OUT port will also transmit MIDI beat clock messages if you are feeding a clock signal into the
CLK IN jack.
V/O:
This adjusts the volts-‐per-‐octave scaling for both the CV OUT and AUX CV analog outputs.
TO CALIBRATE
: Connect a volt meter to the module's CV OUT jack, play a MIDI C7 (note #108), then
adjust the V/O trim pot until the meter reads exactly 6V. You can use other octaves, too, if you want;
just remember that every C note should output an even voltage value:
