Copied the system from a post made by Maison Vague on GS.
For the past several years, I've been slowly putting together a Buchla 200 (not 200e) inspired Doepfer A-100 system. To roughly approach the functionality of specific Buchla modules, I've been using this list as a guide:
254: A-138e 3 way crossfader and A-133 Dual VC Polarizer
259: A-111 VCO, A-110 VCO, A-137 Wavefolder, A-196 PLL, A-132-3, A-134-2
266: A-149 SOC and A-118 Noise/Random
281: A-143-1 Quad A/D and A-172 Max/Min
292: 4 x A-101-2 LPG and A-138 mixer
I've been pleasantly surprised at just how far I've been able to get using only Doepfer modules!
