Casio CZ/ VZ/ FZ - Pro Series

CZ sysex communication does not follow the same handshaking protocol everyone else uses, but its close. CZs do not send the 0x0F7 byte after every sysex message; it will do ||: data - acknowledgement :|| and will only do the 0xF7 at the end. This can cause problems for software that doesn't know about this little CZ quirk.

As for how the CZ receives bulk data dump requests, sends data, and receives data, there is no better source than the CZ MIDI Guide from 1985. (I think its in the files section either here or in the spill over group.)

I haven't done sequence transfers with the CZ-5000 in decades, but it is pretty straight forward if you follow the CZ handshaking protocol. The CZ-5000 is always listening for incoming sysex commands but only responds to one's intended for the CZ line of synths.

Hope this helps.
