I think it depends which direction you want your modular integration to go.
After I started with Rings/Clouds I got Braids so I could have another voice to control from A4 (Braids already has a built in AD envelope). After that it was really about adding more modulation so I picked up Tides. Then I wanted some mixing/VCA so I picked up Veils.
The breakthrough for me was to get Pamela’s New Workout and its exp1 expender. Pam is now the main clock with MIDI out to A4. Check https://www.youtube.com/watch?v=Alu_cCDJIts where there is a section at the end on the A4.
After getting more modulation then I thought I needed to get more utility modules, I know they are important and I don’t understand them all yet, I just know I need them and it’s just a matter of understanding why.
So I recently added Links/Kinks and Blinds. I also got Ripple as an extra filter.
Next I can get more interesting flashy modules I supposed. I am thinking the ER-301 so I don’t need to get an octatrack.
Damn this rabbit hole…
