First time posting.

Got into modular back in February. Next module purchase in July will be the Maths. So I'm currently really enjoying the Bloom, tides, and Dixie2 and making quite a few melodies and soundscapes. I would like to do more modulation and experimenting with automating sounds (especially the tides and filter). So here is my question: what do I fill the last 4 HP with? LFO or VCAs?

Currently looking at an OHCD. But not sure if that would be as useful as a dual VCA in that space.

Thoughts? And thanks.
