I would recommend rearranging your rack for easier workflow. Voices, filters, and VCAs together at the top, with sequencing, modulation, and utilities (envelopes, LFOs, etc.) on the bottom row. This will help you visualize audio and CV flow a little better. It may also help you see what you might be missing. Try to imagine how a MiniMoog's signal flow is arranged. That is a popular synth for its ease of use.
Have fun and good luck.
