Greate project @Saotome!
I have exactly the same questions as @Reesepuffs. Next on my todo-list is a Daisy Seed-based FX unit, and it would be cool to include CV modulation into it.
Well, I could always look at the Daisy Patch circuit and copy that! 
I will do my multi-fx-unit in C++ code as soon as I finish my OscPocketD (OscPocketD - Portable music tool (sequencing drums and synths) - #10 by StaffanMelin)!
