The Differential Rectifier (Diff-Rect) can be used as a complex audio waveshaper, gate or pulse generator, CV shaper or to generally mess things up. The diff-rect is a hybrid of two basic op amp ‘building blocks’ – a difference circuit and a rectifier. Not sure if the two have been merged together before. It is probably a bad idea except for synth use, where it is a wonderful idea!
The Difference Rectifier has 4 inputs (two + & two -) and two outputs.
