Update 1.1: Added a "Split" knob, which offsets the two sides in opposite directions. At around -0.5, this mimics the behavior of the "Crease" input on Mannequins' Cold Mac Eurorack module. At high positive values, this will turn your signal into a square wave. This knob is especially useful when using my Wavefolder Block afterwards in the signal chain. This is also really useful on LFOs if you want to add a bit of discontinuity!

The fifth Block in Michael Hetrick's "Euro Reakt" series.

This is a waveform processor based off of the Doepfer A-136 ( This takes in a waveform and breaks it into its positive and negative components. The individual components can then be modified via gain and clipping controls. In addition to the A-136 control set, I have added an output attenuverter, and modulation on everything.

You can use this for a variety of distortions, like half-wave and full-wave rectification. You can modulate it to unlock all sorts of new waveforms for your oscillators.

In general, I highly recommend using this with simple signals (oscillator waveforms, except for square waves). It doesn't sound too great on complex material (i.e. guitar, mixes, etc.), but is extremely useful otherwise. Try using it on an LFO to shape your modulation signals! If any part of this description seems weird, try this Block out with the standard library Scope.
