DESCRIPTION:
Each of the SY-300's oscillators is routed to its own output:

OSC1 - main out L
OSC2 - main out R
OSC3 - sub out R

Each footswitch is programmed to hold an oscillator.

Boom! Super lush tri-stereo drone magic. HOWEVER! This is barely scraping the surface of the potential here. I only played single notes. Imagine stacking six note chords for impossibly dense soundscapes. Imagine adding stereo effects and a second amp to each line! Six amps!
