From the project

TechWave Audio Midi Controller Module

A monophonic MIDI controller Eurorack module using the Raspberry Pi Pico (RP2040).

Note on / off: sends/stops the note and velocity outputs. Sends a trigger pulse on note on, and turns on the gate for the duration of the note. For +10v output, responds to C-1 (note number 0) to B9 (note number 119). For +5v output, responds to C2 (middle-C, note number 36) to B6 (note number 95). Volume: increases or decreases the velocity output. Pitch bend: modifies any currently playing note. Adjustable range from 0 to 5 octaves. Sustain: holds a note on while the sustain is active. Aftertouch: selectable…
