How often do you actually see yourself reconfiguring the midi channel etc.?
Even if you only use midi channel 10 for all your drums, 128 notes will
cover a lot of rhythm boxes.

If you really want a UI, what about a separate programmer for all your boxes
that connects via midi.
You could use a small serial EEPROM to store the configuration in each
device, and re-configure them using sys-ex when required.
