That Delptronics has you covered...it's got a rim and woodblock, and both have CVable pitch via the LDB-2x. As for DAHDSR, jump over to Ladik's EGs, as they have a number of extended ADSRs there, all cheap, all 4 hp. You could configure something a bit more bespoke with those.

How to keep modulation patches straight? Hmm...well, colored patchcables might be a way, but I sort of rely on the certainty that there's going to be some of Eno's "happy accidents" from time to time. This way, there's always a potential for humanizing error to creep into the process. But that's just me...anyway, you eventually get to a point where all of the patching and crosswiring becomes second nature. You'll know that's happene when, at some point, you'll notice you're simply moving around with the cables and your hands drift to the knobs on instinct. That way, not only do you know you've got the instrument in your head, you'll also know that you've got the configuration right for how you work.
