Casio CZ/ VZ/ FZ - Pro Series

Joaquim,

I don't think I've seen a dump of the CZ-1 ROM anywhere in all my
hunting around the web.

Your idea for reprogramming the mod wheel is interesting, although it
sounds a little intimidating to me.

If programming the envelopes (etc.) is the problem, maybe an easier
answer would be to use a higher level programming language to make a
nice application for a computer? It's so easy to interface the CZ-1
with a computer, and it has a decent set of sysex commands.  You could
have the whole computer screen to create your sounds, all the settings
at once, and not even use the little LCD.  I guess that wouldn't be as
good if what you're looking for is real-time or performance control. 
But it would be good if all you need is better programming
capabilities.  And it wouldn't require disassembling, flashing ROMs, etc.
