One thing I’d like to chime in with is that even by themselves and with very little modulation, the outputs sound great. Listen to the final out, or the bottommost output with the funny stairsteppy waveform. Wiggle the knobs. Doesn’t need to be more complex than that. (EDIT: My point here was that even if the Cs-L offers a ton of options, very simple patching can yield great results with this thing – don’t let the versatility daze you.)
Of course, that possibly doesn’t help at all
What I enjoy doing is patching envelopes to various destinations. Kicking the wavefolders, or the modulation index, with a quick envelope to give a sound an attack phase is very nice. Also explore the button combos, they give you a lot of results that at least I don’t really understand as of yet, but they sound great.
Things I’ve yet to fully explore are at least the various sync options, plus I’d like to dig deep in the ring modulation/AM section. The latter can give very nice, fragile tones.
