I have been trying to figure out the ideal ratio of VCAs to other modules in a larger setup. Right now in my 14u MDLR case, I have 8 VCAs and two large voice modules (Trident triple oscillator, Hertz Donut complex VCO) and a Plaits plus 4 WMD percussion modules. I also have a six channel mixer (Befaco Hexmix) and an octal attenuator with Erogeneous Tones Levit8. Do I have enough VCAs?
