My take on this...it's unusable. There's no mixers, attenuators, only ONE thing I could refer to as a VCA, and there's a mult in this tiny build where something FUNCTIONAL could have gone. Worse still, it's EXPENSIVE unusable.
The Cwejman and Schippmann modules on this site are really on here mainly as reference. No one in their right mind uses these unless they're capable of pooping Krugerrands.
Follow sacguy71's advice and get a copy of VCV Rack. With that, you can build up something very much like the above...and find out why you'll hate it literally in SECONDS if you made the capital mistake of actually building it. And conversely, you'll find out how to alter the above with the "boring" modules to actually arrive at a workable result...which you desperately need here, because all you've got at present is a boxful of expensiveness.
