Neutral Labs released MEG
Neutral Labs released MEG, a unique kind of waveshaper. Instead of folding the wave back in on itself like a common wavefolder, it shifts parts of the wave up or down, with the shifting threshold being adjustable. The resulting 2 half-waves can be flattened one by one, essentially morphing into a half square wave and eventually a full square wave. Essentially, it will add pulse-width modulation (and more) to any kind of wave.
