[sdiy] Variacs and modular synths

[daryl groetsch]

thought i'd give an update,
got it working! it does some interesting things. my
oscillators pitches when down, filter cutoff frequency
when down. everything started sounding warbly and
unstable. got it down to 40 percent or so! really fun,
can't wait to see how it effects other patches. 

best, 
Daryl
