@Markay - you are right about fast support! Arno replied back to my query about the parameter question in less than an hour - here is the reply in case others are trying to control this plugin from any controller:
Everything is divided equally into 6 zones, so 0 to 21 is C1, 22 to 43 is V2, etc.

@Mate Stubb - Yeah I get what you are saying....how does one "sample" chorus and vibrato....I'm guessing that it probably has some kind of tech built into it whereby they sampled C/V on an arbitrary drawbar combination, then did some kind of modeling off that for when you hit the switch. I'll put a query to Arno as well as point him to this thread.
