I did some further research and have been able to produce the appropriate MIDI CC data: See threadmaxpiano wrote:

Yes CC64 but I don’t remember if anyone has analyzed the values sent at each intermediate step (a MIDI Monitor on a Nord using the original would quickly reveal that), you can try dividing the 0..127 interval in equal steps as a start.gitarrenzupfer wrote:awesome thread, awesome arduino-project from awawa,
a question about the triple pedal
Are midi-CC data sent when the sustain pedal is pressed (with half-pressed and damper noise)? If yes, which?
CC# 64 0|127 or something else...?
One of my friends analyzed CC values with the triple pedal. As maxpiano wrote, the CC was sent to CC#64 but its values seem complicated. The CC values were different every time the pedal was pressed.maxpiano wrote:Yes CC64 but I don’t remember if anyone has analyzed the values sent at each intermediate step (a MIDI Monitor on a Nord using the original would quickly reveal that), you can try dividing the 0..127 interval in equal steps as a start.gitarrenzupfer wrote:awesome thread, awesome arduino-project from awawa,
