dual noise source with crude VCAs
Two flavours of noise, one is pretty standard transistor white noise and the other isn't really noise but a buzzy mix of 6x 40106 oscillators mixed together.
Both make good starting points for percussion sounds and each has their own crude VCA which acts as a level control with no CV inserted.
The VCA inputs also work well with audio, the noise will ride along on top of the +ve portion of whatever waveforms you shove in there.
No prizes for guessing what MIX OUT does.
The HEX OSC and inbuilt VCAs borrow ideas from circuits found in the TR808 but please don't expect to get any 808 sounds out, neither was that ever at all my intention.
4HP, +12: 3mA, -12: 8mA
