Casio CZ/ VZ/ FZ - Pro Series

Thanks, Gordon.
I was in the car when this turd got emailed earlier.

MIDI is, as you state, fixed at a baud rate of 31250 bps. That's the very
definition of MIDI.
And, truth be told, if you look at the system architecture of earlier
synths, they could not take this rate in any sustained manner. You can send
note ones and off pretty fast, most modern synths can take fills speed more
on and off.
If you take an older synth - they cannot even take full back to back note
on note off. They'll start dropping notes or losing note offs.

Also. Latency. A cz-101 takes 8 ms to turn a note on aster receiving the
completed note on message.
I'd imagine the rest of the cz range is the same.
You've got phase accumulators And envelopes to reset. Fortunately, these
are achieved in hardware via the 93x series of chips. If these were done in
software, it'd be an even longer delay.
