So, by it "not playing", do you mean ChucK simply doesn't indicate

it's sporking the shred at all? Or that you don't hear a sound?

Good point. Chuck says the shred is sparked, we just get no sound.

Have you tried stuff like editing the offending file to start with a

debug print?

If I run either file alone, they each work, individually.

Assuming that the filenames indicated are the actual ones then that's

not it, those should be legal under both, but Windows and Mac

potentially use slightly different non-printable characters for stuff

like the end of a line. You could try opening and re-saving them using

a Windows native text editor or some tool to strip those characters, I

forget the details (stuff like cariage-return....) but your favourite

"serious programmer's editor" should have a tool to convert/strip

those. That might help?

This sounds like a good lead. I think he wrote the files in miniaudicle on Windows (although he is running them from the command line), but he may have copied/pasted some of it from some Mac generated files I gave him. I'll follow that up.
