Um, re ChuckSound -- I still need a clue re how to add a chugin... ?![Using a python script to feed the lines via " > testfif " , csound -L testfif still waits until the script exits to play -- although now the timing between notes is preserves.]Sorry, this last was not a chuck problem-- something to do with closing the fifo on the writing end before it can be read.

[Supposed to be there in the example, but not for my usage.]Main glitch now: Chuck starts with an error message because csound is trying to use the audio output. Csound does play the two notes -- but only after chuck exits. Csound has received them before this -- and sends them to dac; but they play simultaneously later, when chuck lets go of the audio...

So it depends what you mean by 'easier.'Chuck does seems like a pretty heavy-duty program to use as a midi-timer; last night I worked out a short python script that seems to do the job; but chuck -- if it had the right file-handling capabilities -- is more specifically designed for coordinating a musical process, and might work better.

Maybe a naive question: but is there any reason you don’t want to use OSC protocol for communicating between ChucK and CSound ? I think that’s the easier route.
Best,

If I don't close the fifo chuck merely freezes; if I do close it at the end of each line, chuck continues to receive midi notes but csound doesn't get anything from the other end.
