Tiptop Audio Fold Processor Wave Multiplier

The Fold Processor is a voltage-controlled wave multiplier and sub-octave generator. The circuit is based on a classic diode design that adds odd harmonics by folding the incoming signal, followed by subdivided square waves.

The wave folder creates new waveforms from standard sine, triangle, sawtooth, and square waves and includes a CV input with an attenuator, making it very easy to create beautifully animated folding sounds. Adjustable voltage-controlled Inject alters the bias point creating an even wider palette of sounds.
