The VZ series already has full sysex implimentation for transferring 
patches to and from a library.  The problem is that all parameters 
must be sent at once, making it impossible to tweak a single 
parameter in realtime.  So changing the software in the ROM to allow 
for single parameter receiving should do the trick, but I suspect the 
reason Casio didn't allow individual parameter changing for real-time 
control in the first place is because the processor is way too slow.  
It's of a similar era as the Poly 800, so the cpu is probably of 
similar power, but the Poly probably has a lot less work to do.  The 
VZ10M is notorious for bogging down when too many oscillators are 
open without any hacking done to it.
