I am trying to bring up a MIDI connection between my NeXT and my synth.
The documentation is not very helpful;  in particular it is rather terse
about the hardware interface needed to convert the RS-232 ports to
MIDI levels.  There is an implication somewhere that anything that works
with a MAC will work with the NeXT.  I am currently using a home-built
interface box, based on an 1985 article by Kirk Austin in Mactutor.  When
I turn on the synth, even before I start sending data, it complains
about a MIDI data error.  When I run playmidifile, the synth's MIDI
monitor mode shows data coming across, but I've misplaced my spec and so
I can't interpret the data.

Could somebody who has a working MIDI setup please describe your hardware
for me?  I'm hooked up to serial port A, if that matters.
