> Is this a known issue? Are there combination of modules that can cause this to happen? Could it be the power supplies? I have moved the modules around and found the behavior is the same regardless of how many modules (or which ones) are in a case.

Just a simple idea: are you triggering all our ADSRs using the MIDI
converter? Have you tried to trigger them with something else, like a
sequencer or a pulse LFO signal to see if there is a difference in
behaviour?

Wow, that's some accurate problem reporting :) And what a collection
of synths...
