[sdiy] dumb wavetable question

[karl dalen]

Oh, and it multiplex quite well too so you can make lets say 
8-16 separate oscillators, you need a Video ADC for that but
one memory and a couple of registers or you multiplex the 
video ADC for everything, you multiplex the DAC as well
as usually. Did all that once, the video ADC are a challenge,
particularly the osc encoding part. :)
