Ok, this becomes understandable. But I have no dedicated answer for you.

The only thing I could imagine is, that the trigger threshold for the 
S&H is quite low (lets say at 0.5 Volts) and the Quad ADSR assumingly 
does not return completely to 0 Volts when in self-triggering mode. (I 
know this from other makers envelopes, e.g the ADSR of my Formant does 
not go down to 0 V completely. You have to work with an negative offset 
at the VCA to make it silent).
