  1. Great. Would be even more awesome if it could co-exist with Cocteau (2) expansion board for tweakable sounds beyond traditional 808.

    1. If you look closely at the PCB picture, you can see many unpopulated pots and switches, I believe these are mods already integrated ine the Yocto 2.

      1. Agreed. The only sound i like out of the 808 is the kick. 909 sounds i love, plenty of sonic room to play with and transform them. I feel 808 sounds tend to get messy fast (and i am so sick of hearing that 808 hat everywhere, quit beat repeating and compose a damn drum part)
