Re: Mac, MIDI & FLTK
FLprintk and FLprintk2 are special opcodes, to be used with caution
because a thread is writing to a space exclusive of another thread and
could cause synchronization problems. I suggest not to use FLprintk and
FLprintk2 at all with OS-X, even if I don't know if these are the only
FLTK opocdes that cause problems. Have you tried with the other FLTK
opcodes?

Sometimes it will crash with an "Invalid f-table 1.000000" when there isn't really an issue. Usually a re-try does the trick, but it would be nice to see the Mac version of the canonical FLTK widgets reach a similar functional status as users of CsoundAV regularly enjoy.
