@JimHowell1970, true passive mults are what you want 99% of the time for those 1v/oct cases.
I have a few Noise Engineering modules on the way and since these are sensitive to modulation, would passive mults be enough to tame these for modulation purposes say if I feed an LFO into them? I did take your advice from earlier and order a Kinks and Links as well as larger hex VCA for the second case. Now I need the sequential switch, clock, and logic modules. I figure with the four VCOs and 12 VCAs that should cover that area for now in both cases. I will get these additional tools on Black Friday sale.
