This little module contains both a soft saturation "wave driver" and a wave folder section, with option switches and a Symmetry control to choose different behaviors for each side. There's also a flexible crossfader, and ample voltage control including feedback. In short, it's a versatile sound shaper with a lot of sweet spots. The movie breaks down like this:

00:00 overview
00:37 Wave Driver (I)
03:30 Wave Folder (II)
06:15 enveloping the Shape
08:21 Symmetry
09:18 modulating Symmetry
10:12 modulating Crossfade
11:41 jumper options (AC/DC coupling, phase)
13:42 wavefolder & odd harmonics
15:41 symmetry & even harmonics
16:22 Feedback
17:48 layering w/ 2nd VCO
