Gilles -

I also have a Roland D10 (among other synths, samplers, and rack toys). There
were some MIDI tools written in OS9/C, but most were for the Casio CZ-101/1000
family. Almost all the other stuff is written for the RSDOS environment.

Biggest reason is that MIDI requires a 31250 baud port, and a computer and
buffering scheme that is capable of keeping up with it (at least in bursts).
Because of interrupt latency, and time slicing, OS9/6809 really cannot do the
job unless a) You have a smart interface card that does processing and
buffering or b) You cheat out OS9, and lock your process into the saddle.

There are lots of programs for the IBM, Atari, and MAC that are wonderful for
use with the D10. If you were motivated, writing one under OS9 might not be too
weird... as I said, Richard Johnson wrote a Casio Ed/Lib using technique b)
above.

Good luck.

Pete
