dual sawtooth oscillator noise synth

this synth is formed from 2 sawtooth oscillators, the first has just a pitch knob and the second one has switchable potentiometer or optical pitch control. there is a switchable cross-modulation control that can be varied to produce different types of sync or ringmodulator effects. both oscillators are mixed together with a blend/crossfade pot and the output section has a gate button and gate mode switch that go to the final master volume control.
