Tiptop Audio have just released a new Eurorack module called Fold Processor. It’s based upon a classic diode design that folds an incoming signal to add harmonics followed by subdivided square waves.

Fold Processor

It’s all completely analogue and modelled on the Serge wave multiplier module. At least the first section of the processor is, which routes directly to the output. The second section takes some of the output and feeds into a “square and divide” circuit. This emerges at the “SUBDIV” output. It’s an audio processor and so the sort of sound you get out is going to have a lot to do with what you put in.

The Fold knob controls the severity of fold whereas the Inject knob governs the offset which adds more variations to the signal. Both these knobs can be voltage controlled.

The subdivide output has four divisions spaced one octave apart. Each has a gain knob for mixing the tones.

Tonally the Fold Processor is best suited to pure signals – sine, triangle, square waves. However, inputting more complex sounds produces a cool distortion effect. As you fiddle with the Fold and Inject knobs you can get a lot of movement in the octaves and pulse width modulation effects.

The Tiptop Audio Folder Processor is available now for £129.99. More information on the TipTop website.

Their promotional video doesn’t really tell you anything, but this one from Station 252 gives a much better idea of what it’s capable of.
