	A MIDI interface is no more than an opto-isolator and a buffer. All
MIDI interfaces for the Amiga will be the same from a software point of view.
IT IS NOT AN AFTERTHOUGHT !!! The Amiga ROM kernel has ALWAYS supported the
MIDI data rate (somewhere between 31k & 32k baud). The flag for the serial
device is called SERB_RAD_BOOGIE and is documented in the Amiga ROM kernel
manual for vers 1.0!

	Incidentally, the Amiga hardware supports serial data rates up to
292000 baud, although it is pointed out that the software may not be able
to keep up with data at this speed. (RKM 1.0 p3-168) 

	Finally, MIDI interfaces are dead easy to build and only cost about
$12 if you know where to pick up cheap parts (Active Surplus, Toronto;
Halted Specialties, Sunnyvale (I think)) The was an Amazing Computing article
about this just a short while ago.			...sjk
