My current rack is like this:

What modules I can add to it to extend the sound possibilities of Moogs?

FH-2 is sending sequences (also can act like LFO), so I don't need a sequencer and not planning to create a self-contained generative system (I want generate this from computer).
Using that module, I can also send sequences from some gear like Digitakt.

Also, I can send 2 outputs from my audio interface using Ableton's CV tools for some purposes.

The universal thing I want to add is a Disting MK4. But what else?

I thought about adding a Maths, but it is pretty big for this small skiff, so it should be reasonable.

If matters, I'm creating melodic ambient-atmospheric stuff, but I want to keep it somewhat universal to use as instrument, but for sound design purposes too.
