[sdiy]CV-Quantizer/Wavetable Osc and static RAM

[Jason Proctor]

this looks great!

quick question: will there be any facility for increasing the sample 
RAM? with 16x16, there will be the same 16-sample wavetable 
manipulation restrictions as on the Miniwave, which prompted Cary & 
me to make an expansion board.

this isn't just for more waveforms, but to allow smoother wavetable 
transitions. our Miniwave expander board has 32 wavetables x 64 
waveforms, making it effectively a PPG oscillator and therefore much 
more effective at evolving-waveform type stuff.

thanks and good luck with the project
