I would consider adding a way to attenuate, offset, invert - for more control over those Ochd LFOs (there was an Ochd in the rack, seems to have disappeared). Sure, you can use the Maths but then they’re all used up.
Acid Rain Junction is pretty compact, or a Doepfer A133-2, or a Befaco A+B*C.
Assuming you’re into ambient/Krell type stuff since there’s no trad sequencer here?
