first I would get a bigger case (6u/104hp is a good sized starter case) so you can actually build a modular synth in it rather than a collection of a few modules that won't play nicely together

you need to add modulation, envelope generators, utility modules

either a bigger case or cut back to 1 or 2 voices at most - otherwise not enough space for the support modules you need

Thanks for the great feedback! I’m such a n00b and could use some more examples of what you mean by utility modules. I have 8 LFOs, and 6 VCAs — what other basic utilities do I need other than an envelope generator? Pardon my ignorance
