Looks like a nice list of modules cherry-picked into a rack.

If you wanted to change the polarity of a CV signal... how would you do that with THIS rack?
If you wanted to scale a CV signal, mix two CV signals... again... how would you?

I don't see any traditional ADSRs. Why not?
The Batumi can always use the Poti expander. In a large set-up, it's very much worth the 3HP.
The only dedicated effect is a Chronoblob... if you're doing ambient, where is your reverb?

All in all, this looks like a fantasy build that has very little study behind it. Sorry to be so harsh. But if someone else putting together a rack sees this they should take these comments to heart.
