[sc-dev] Re: [sc-users] MIDI event handler threads

[James Harkins <jamshark70@xxxxxxxxx>]

While working on the MIDI helpfile, I found an issue with this: there's 
no clearly defined way to stop a responder. You can stop the routine, 
of course, but you still have the MIDIEvent in the MIDIIn classvars, so 
its conditions still have to be evaluated even after the routine is 
gone. Very untidy.

I guess the user can do something like:

onRoutine = fork { |ev| loop { ev = MIDIIn.waitNoteOn; } };
onEvent = MIDIIn.noteOnList.last;

...

onRoutine.stop; MIDIIn.noteOnList.remove(onEvent);

... but that's a bit hacky, isn't it?

Can the MIDIEvent perhaps detect when the routine has ended and remove 
itself? Just thinking out loud...
