Things I might be missing are CV quantizers or mixers. I'll need to built the rack myself (especially as I want cable guides), and then discover what I still may be missing.

definitely appears to be missing quanyizers... more mixers would also be good... probably at least one cascading vca - as it looks like you are low ion vcas compared to envelope generators - maybe a matrix mixer - and fill the left over space with other utilities...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
