Couldn't get the code to run with Perl on Mac: $ plenv exec perl midi.pl Not enough arguments for main::pedal_notes at midi.pl line 107, near "$note)" BEGIN not safe after errors--compilation aborted at midi.pl line 150. I got something similar working in Supercollider though, which has a lot of tools for these sort of things, eg: MIDIIn.addFuncTo(\noteOn, ~myNoteOnHandler);
