Hi all. Here's a link to my current rack.

I would use a link but it won't update properly so this image is most accurate.

What do you think I should fill those slots with? I've got the Es-8 and Es-3 bringing in LFOs, 1V/Oct, etc. but feel like I'm missing clear choices for utilities or sound shaping.

Thanks for any ideas.
