Thanks for the link. I have gone over it and read some of the links off that article.

VCAs? I have VCA in the Mother 32, but not sure of its capabilities or quality. Also have an Intellijel Quad VCA in the mail. My experience is limited to hardware synths the Roland Juno and JX10. Quite completely different. I have no, or vary limited experience with VCAs. In my reading I know they go beyond a mere amplifier. VCAs can can control filters, envelopes, gates and the like by controlling CV inputs...is that correct? Again no knob twisting to actually see this action ;)
