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...
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.
