I am a beginner with ANA2.
I can remember I watched a tutorial where he created a vibrato on a lead patch.
He used G-Env to create the vibrato-pattern, then routed so that he could choose where the vibrato should affect the tone in time. Let's say I have a long note playing, and I want the vibrato to start after 0.4 sec.
I can't remember the routing, only that he routed G-env to Pitch coarse or something, and then to AMP env or MOD env to control the time.
