daaaaaaaaamn...!
Yeah, this is pretty spot-on. The only thing I would change out here is to toss the Doepfer A-140 and instead put two Ladik xADSRs in...the 'x' part being for the additional function that some of theirs have, such as gate delay, hold, initial level, etc. You'll be glad to have an extra EG with the Veils in there. Maybe a little bit of regrouping for ease of navigation, also, but this is a hellacious M32 expansion rig. Make sure to get some in-line mults, also; cramming in an extra 2hp would be a chore here, so that's definitely the better route.
Exactly right about the 4ms Row Power 40s, also...the M32 (and DFAM, fyi) has a power inlet, but the empty 60hps don't. In fact, that same power supply is what Sweetwater bundles in their 'add-on' bundles, and it has more than ample current to deal with these dinky cabs. Should be nice and stable and run pretty chill.
