The Doepfer version also requires additional modules: a "minimum" of 4 extra
VCAs and VCO / VCF / VCP (?)s, according to the website. It also only uses
saws and triangle waves. Square would be useless, but sine would be nice.
I'd like a MOTM version to be a little more "complete", even if it meant
that it only had 4 phases.
Hmm, I'm not feeling coherent. Did that make sence? Or even better, is it
remotely reasonable to get 4, 6, or 8 VCAs, VCFs, and LFOs in one package,
with varying LFO shape...?
