| I can't test MIDI at the moment, but I'll keep that in mind
and have a look later.
By the way, I have added a summary of tclcsound commands
in frontends/tclcsound, command_summary.txt. I'll work
on a proper documentation for the csound manual.
In relation to realtime, portaudio is a little smoother with
tclcsound than coreaudio, when pausing and then
playing. This is because of the way coreaudio works;
I might be able to sort it out in the future.
