The Fold Processor from Tiptop Audio is a wavefolder, or wave multiplier complete with voltage control. Along with this is a sub-octave generator capable of providing /1, /2, /4, /8 subdivisions, all of which are mixed out of the Subdiv Output. The wave folder section can take clean sine and triangle waves and morph them into beefy and rich waveshapes unlike any other. The output of the sub-octave generator provides all squarewaves. For getting timbres that no sawtooth can create, the Fold Processor is there.
