This module takes a MIDI keyboard as input, generates three frequencies through three oscillators. The Center one is just plain, the Left is modulated higher and the Right is modulated lower than the center. The Spread knob makes the distance between the high and the low pitch bigger. When spread is 1, the difference is 54/55 (=432/440HZ) and 55/44 (=440/432Hz) from the center frequency.
You can vary the Spread and the Waveforms and toggleeach oscillator on or off.
