I don’t know if I’ve missed something or if this has been discussed before but here goes:
Most of Renoise’s functions can be mapped to buttons or dials on MIDI-controllers but NoteOff’s can (strangely) only be placed using the regular computer-keyboard(?) It would be very useful if NoteOff’s could be MIDI-mapped as a toggle-switch. I’m guessing there’s probably some third-party plugin or LUA-script that can accomplish this but I think it should be implemented natively in Renoise.
