Caustic Song file (optional):
Add one part inspiration from Ian and Scarabee's recent sharing with the pulse width, add another part reading about distortion and the use of amp cabinetry to tame the distortion, and one more part on sub bass sounds from Sound on Sound and I came up with this modular that makes some pretty interesting sounds that could be used in dubstep/brostep.
Before playing with the knobs, first try the different sounds across the keyboard. C5 is pretty wild.
I've been wanting to play with modulated sounds using the envelopes instead of lfo's for some time, but after reading Sound on Sound, it was finally time. I think next I'll take Scarabee's recent idea and use something like the 8-bit instead of the envelopes. No time left today though.
Update: I updated the file. Right before I sent the first one I found an issue with the compressor in the master section. Fixing it made the filters in the second modular unnecessary.
