The only dedicated wavefolder I have is the Fold Processor from Tiptop Audio and can't recommend it enough. https://www.modulargrid.net/e/tiptop-audio-fold-processor

Warps can work as a carrier oscillator. I like the Lxd for the strike input, I have that on my DPO and I think it's the same one, just patching a sine wave into it has dramatic rhythmic effects.
