Midi Comunications

[Kurt Kaufman]

Perhaps the most challenging aspect of handling MIDI data through 
whatever port (USB or serial) will be the "clocking" issue:  The volume 
of data may be small compared to audio or video, but the continuous 
synchronization of the pulse between an external MIDI device and the 
computer is critical.  Does anyone know of a good reference for this 
area of MIDI programming?  (Re: OS X) Has Apple made available 
information about compatibility with its "Audio MIDI Setup" utility?
