Hmmmm, on rev M2A (the last MIDI version) there is a gap in the MIDI
note-response (send note messages to the OSCar going lower and lower,
somewhere in there there's a gap of two notes!)

Personally, I'd quite like to get rid of the cassette-save/load routines
and, if necessary, get rid of the sequencer (which I have never really
used in anger), and perhaps introduce some velocity-sensitive operation -
maybe even a `sixtrak-like' voice parameter edit using continuous

But first, I'll need to understand Z80 assembler code!!
