Recommend me some nonlinear circuits modules

I want to order 4 NLC diy modules and I'm looking for suggestions.

I make percussive loops with FM voices, distortion, ring mod and wavefolding. Think dubstep bass lines, lasers and effects that are abrasive and glitchy. I often turn melodic sequences into atonal rhythms.

Because I like these loops to be repeatable it's not possible to inject much randomness. I need my sequence to sound the same each loop.

Looking for recommendations around trigger or audio processing modules that do these things well.
