The Sawtooth Stack is a swarm of 5 triangle core discrete oscillators with the unique waveshaping from the Foundation Oscillator. The pitch Spread of the oscillators can be voltage controlled and they are stretched from left to right through a stereo VCA. The tuning and volt/octave tracking are calibrated when the autotune button is pressed. Notes can be played with MIDI, plus all the main panel controls can be controlled by MIDI CC’s, with their CC numbers shown on the panel below the controls. In the waveshaper section, Timbre crossfades from a sine wave to a saw wave, Richness multiplies the saw wave. The Envelopes are Rise-Fall type, with a range of 2ms-10sec per stage. End pulse outputs allow looping and chaining. The output is stereo, but if only one jack is used, all 5 oscillators are included. The Sawtooth Stack is 42HP and 16mm deep, allowing it to be used in a Black Box as a stand alone synthesizer.
