Gain, and overdrive. Four curves: soft (warm, tanh), hard (obvious clipping), diode (asymmetric, so it adds EVEN harmonics — the valve/transistor difference), crush (digital, quantised). Not the same as FOLD: a driver squashes, a folder reflects.

soft is warm; hard is obviously clipped; diode is asymmetric and valve-like; crush is digital and gritty.The full reference — every parameter curve, the patching notes and the worked examples — lives in the manual: docs.vimsynth.com/modules/drive.
