3. Handling
The module is preset as a four-way MIDI-to-CV interface on midi channel 1. The two controllers
MODULATION and PITCHBEND also work on this midi channel. Send notes from a connected
MIDI keyboard over an 8 octave range of note numbers 12-108. The module can output the
GATE and CV voltages for up to 4 notes at the same time. The “Round Robin” algorythm is used.
If more than 4 notes are pressed at the same time, the last played note replaces the first play-
ed note.
Classic standard connection in the modular system:
Connect the GATE output of a voice to the GATE input of an ADSR generator, the NOTE output
to the 1V / octave input of a VCO and the VELOCITY output to the CV input of a VCA. You need
this four times for all voices.
The CV output MODULATION can be used for filter modulation and the PITCHBEND output for
pitch changes of the VCOs.
How to change the MIDI channel:
Press the LEARN button once (until it flashes). Then send 4 notes in succession on the same
desired midi channel (the GATE LEDs light up in succession when they are received). After
receiving the fourth note, the LEARN function ends automatically (LEARN key stops flashing).
The new midi channel is saved permanently. This now also applies to the two CV outputs
MODULATION and PITCHBEND.
