I'll look into the other VCOs. The first 1U module on the left is the Intellijel Midi 1U. It has outputs for a clock (and at a 1/16 rate), pitch, gate, trigger, cc, mod wheel, velocity, run, and reset. I was thinking that I would use the 4 4-out mults I have (the 2x4 part of the Palette and the 2x4 module) for the gate, pitch, clock, and have a 4th one as patch-dependent. The velocity out I would connect to the 1U VCA (which is the sole reason for the VCA in the first place) which would be the last module in the chain before I send it on out using the Line Out 1U module. I would use this with an Arturia Keylab midi keyboard or one of my other synths that have a midi out. I go back and forth with adding the Dnipro Modular Dot sequencer. If I were to add the Dot module, I would replace the Behringer VCO with a smaller sized VCO (probably a duplicate of the other VCO I currently have in there). I like the idea of having a sequencer but I don't think I would get a ton of value out of one for the kind of sound I would use this synth for.
I didn't know of the Deepmind but now that I have been looking into it I am strongly considering buying it
