Here is my 3rd iteration:
ModularGrid Rack

I'd appreciate any feedback especially on the layout. I tried to organise the modules in a way that made sense in my head, but at this point it is mostly theorycrafting and might not make the most sense during actual operation of the synth. So any and all tips are welcome.

I felt like I did not want to mess with samples and I found about Blck_Noir so that replaced Bitbox. I read some mixed things about it, but I'll have plenty of time to research the drum section while Model:Cycles plays nice FM drums for me.
