[sdiy] Tempo/Clock-to-CV conversion

[anthony]

Check in one of the "Device" volumes for a "pluck follower". I think just 
googling "pluck follower" should take you there. It's part of Craig 
Anderton's AMS-100. It's in "Device", 1-11, p. 12.

The idea is to use it after a normal envelope follower and the faster you 
pick the more voltage accumulates. So it is sort of a sample-n-hold, but 
more like a follow-n-lag, but the lag is pretty high.
