Barong Analog Synth in Action video from Skonto

Stan sent me a link to his blog where he posted a video over the weekend of his synth in action. Pretty interesting and totally unexpected sounds. It sounds and looks like there are two oscillators present. One acting as a drone controlled by a pot, while other is controlled by light for crazy whigged-out solos. The only thing to make this better would be an addition of some delay effects. Possibly even different amount for each osc.
