BASSLadder Snarl

Osc 2 moves the cutoff at audio rate through the ATTENUATOR, so the filter snarls with sidebands of its own, and the two oscillators a few cents apart make the snarl roll slowly. Hold notes to hear it churn; dig in with Growl. Macros: Growl, Cutoff, Bite. Macro 8, Master, is the output level.
