Ahh, I see. Beauty lies in the simple things.
The "crude" diode approach has the advantage of being faster, of course.

jurgen,
it is an extremely simple design ! it trades off precision for basic
functionality and uniqueness. it is worth adding to a modular on this basis
alone plus, for me, being interested in algorithmic type sound structures, it
helps create the ability to do logic desicions in conjunction with electronic
switches and assorted sources of c.v. or gate/trigger/timing functions.
