The referenced post asks if sources close to Dave Small can confirm whether
or not he's working to bring up Mac MIDI.

	Sources close to Dave Small report that he dosn't have many good ideas
on how to do this, short of rewriting some low-level I/O routines in some
Mac programs.

	The basic I/O isn't the problem; I can do that. The *timing* is the
problem. The typical MIDI output needs to be interrupt driven, and uses the
VIA timer chip for the interrupts. There's no such chip on the ST. It also
uses
the SCC chip for serial communications at MIDI speed.

	Now, of course, if someone mounted a VIA and SCC chip on the Atari
bus ... (no comment).

	-- thanks, Dave Small / Gadgets by Small
