Sawtooth Stack

A swarm of five discrete triangle-core oscillators carrying the waveshaping of the Foundation Oscillator. One frequency control tunes the whole swarm; the Spread control, itself voltage controlled, fans their pitches apart or folds them back together, and a stereo VCA stretches them from left to right across the image. Two envelope generators with separate rise and fall times sit on the panel, each with its own gate input, manual gate button, end-of-cycle output and c.v. output; one is printed as the source for the harmonics section, the other for the output amplitude. The harmonics faders set richness and timbre, each with an attenuator and a control input. Frequency takes a v/oct input and two attenuated c.v. inputs, the oscillators tune themselves, and MIDI note input has a socket of its own. Every control is given its MIDI continuous-controller number on the panel.
