See the provided example config on how to configure your controller, it should be pretty self-explanatory.

The midi library used seems to recognise NoteOff messages as NoteOn messages. However, they can still be recognised by checking the velocity, which is always 0 in NoteOff messages. A workaround has been implemented.

### Finding the MIDI channel and note / controller
|
||||||
|
|
||||||
|
Many vendors provide official documentation on the MIDI commands sent by their devices, but if you are unable to find them, you can use `aseqdump -p <port>` to print all MIDI messages sent by your device. Simply interact with the controls you want to map and you will see the corresponding messages.
