UME should sound great on the ROland piano.

The RS232 and MIDI Paks are similar, except the MIDI Pak runs
at one Baud rate of 31,250, over three times faster than the RS232 can,
and uses a different electrical output (a 5 ma current loop
instead of +-12 volts swing).

Also Rat Shack sold the RS232 Pak, and SPeech Systems cum Rulaford Research
sells the MIDI Pak.

It's possible to hack up an RS232 or DC Modem Pak into a MIDI Pak,
tho so far nobody's written up cut-and-dried cookbook instructions
on how to do this.

If I get that MIDI recording under OS9-L2 working, you and everyone else
will hear about it :-)
