[sdiy] droop of sustain level in analogue ADSR?

[Oakley Sound]

There's bound to be the odd circuit that doesn't behave right. The ADSRs 
on the Minimoog Voyager have/had some strange drifting going on at very 
long release/decay times.

However, one could argue, if one was being really pedantic, that the 
sustain level is always moving since it forms part of a decaying curve 
whose time constant is set by the decay pot and timing capacitor. Not 
generally regarded as a problem... but can lead to a noticeable effects 
when the ADSR is used to control pitch.
