[sdiy] Sweep through waveforms

[Peter Grenader]

I spent an hour or so looking over this when i was first posted, and this
circuit of Grant's's has about a billion uses that would be extremely
interesting.  My first synapses were using it as an output select for a
fixed filter bank  or a frequency divider- t'would be interesting in dot AND
bar mode.

The vactrols, being the sluggish beasts that they are, would augement the
3914's decoding and give you some interesting morphing effects.

And imagine if the same signal was put into each channel. If you didn't
incorporate the summer but  had separate outs for each channel and   slowed
down the vactrol response time further than it is aby design, me thinks it
has the makings of a great multichannel panner.

I never thought of a multiwaveform selecter Grant suggests (ala the NTO),
but yeah, this would be sweet as well.
