nand synth

works like this:

- 4 schmith-trigger based oscillators, cap select (decade) + pot

- chained: 2nd AND gate input turns oscillator off

- the NOT in the chain prevents subsequent oscillators from being OFF
  at the same time

so, the the first oscillator A produces a square wave. during A's ON
period, the second oscillator B produces a square wave, during A's OFF
period, the second oscillator gives ON. and so the story continues...

....AAAAAA....AAAAAA....AAAAAA....AAAAAA
BBBB.BB.BBBBBB.BB.BBBBBB.BB.BBBBBB.BB.BB
C.C.CC.CC.C.C.C.CC.C.C.CC.CC.C.C.CC.CC.C

etc

this can give a quite complicated pattern after a couple of steps. one
thing is missing though, there is no resync: all capacitors keep state
between oscillator ON/OFF switches, so no formant-like tricks.
