Turns out I can't today/now atm.. for some reason.. all I did was have a RS5K, Env Gen, RR2 Filter Moog, Replika, and as soon as I activated Env Gen, it would "lag" and sound un-useable and I could just SHIFT click Env Gen ON/OFF (bypass) and it would go to normal to not, normal.
I will report back when/if I find something out that is reproduceable on Fridays.
A moment in time later: Found it! bad SmajjL!
If RR2 Env Gen is set to MIDI Out (ALL) then this will happen, so, I won't.
