CV input for live control over envelope settings

[TME]

Fingers crossed for these, in addition to any other parameters in the Nerdseq that can be reasonably manipulated through the CV inputs.

Edit: Basically any implementations that open up axes for performance and impromptu variations. I just realised that bipolar CV input can already control probabilities for FX1..4 and row probability in 1.23A, which is also really cool!
