Xpantastic!

I have looked at doing this, but increasing the micro speed is not all.  The analog multiplexer circuit ultimately determines the update
rate of each parameter eg..  env attack etc...,  which in turn limits the speed of the mod souces.  So.. the resistor/capacitor values in each mux circuit (one per voice) would have to be changed along with the code. I would hate to hack up my M12 that much. There is an AKAI out there 
that I believe has the same CEM chip set. It might be a better victim.      
 
BTW   Putting a a sharp, short  evelope to the FM at the beginning of the sound can add some snap or bite to a bass patch.  Learned this from an artical by Wendy Carlos.
 
 
Best Regards

(I'm not sure if it is the exact same model as the 6809 (B vs E) though). Additionally, there is another mode in the 6309 that has a few "extra" instructions which enable some operations
to be even faster. But this would cause more of an incompatibility until the FW is re-written. However, if any of you are tired of the Xpander/M12's current limitations, a challenge awaits ye.... ;-)
