I'd put Maths in the lower left corner, before the percussion voices,
and put the quantizer and Circles to the left of the oscillators and envelope generators.
Avoid having wires draped everywhere. I love using those little yellow Doepfer wires.
The Wasp and the 106-5 SEM sound different, but kind of the same.
Substituting an A-101-6 Opto-FET Filter would provide more colors.
You are going to need more multiples.
If you had to sacrifice something for a 4HP Rides in the Storm QAM, what would it be?
Mounting a module from 2hp on the end of a row is asking for trouble.
Always a wonky fit and really difficult to get your fingers in there to tune it.
That voice is already covered, I'd drop it, and with the spare space already,
there's your 4hp for a QAM.
Circles (and techno!!) wants a clock. I know it's costly, but I'd drop the A-136 waveshaper,
and put a Pam's Pro Workout in the far left someplace. Maybe near a mult(!).
The A-136 doesn't give back much for the space it takes up anyway.
Pam's can do a lot of the things the noise generator does too, plus 7 other outs,
in the same space. It could also help with the lack of LFOs here.
