they are, but if you insist...
Actually doing some waveshaping would be hairy, as there are only two outputs
from the osc chip, 4 voices on each, with 4 outputs from the dividers to make
all those selectable octaves. At least that's what I remember, it's been a
while since I've looked at the schematic. Waveshapers would get confused by
more than one note hitting them. Could be entertaining, though...
A much, much better idea... this is SICK... standard cmos gate chips come
with 4 gates to a package. 4 octaves out, two seperate osc's per voice in
dual mode with seperate outputs... Take a standard xor gate chip (74hc86)
and wire it in. 4 seperate ring modulators, each hitting at a different
octave!
I'm going to have to do this now. Oh, the horror....
