You did not read what he said very well.  To summarize:

    >> ALL THE MIDI ADAPTORS PRESENT THE SAME PROGRAMMING INTERFACE <<
				>> PERIOD <<

The only difference in the units seems to be MIDI THRU, this does not
change the above statement.

With a standard exec device interface (midi.device) it would not even
matter if the hardware *was* incompatible between manufacturer's
devices.


>Does the Amiga OS support MIDI devices?  The ST OS does.

Yes, and no.  The Amiga OS support works, but provides poor timestamping.

To do it "right" a dedicated MIDI driver must be written.  Some
developers have chosen to pick up a solution from the Public Domain,
others have re-invented the wheel.  It is not a problem any more
(a long time ago it was).
