S&H - Muddy > Bright + tuned 3rd Osc
By Phin
A third oscillator is generated from a feedback loop in EG1 (and tuned to C in this case using EG1 controls), with its output controlled via the sample and hold to provide a rhythmic tone over oscillators 1 and 2. EG2 reverse out affects the filters to give a nice progressive distortedly muddy to bright sound over time.
