pitch control is achieved via pots or photo resistors (switchable for each channel) – the oscillators modulate each other but their signals also have separate outputs – 6 rotary switches alter filter settings and can extremely change the sound and interaction of the oscillators – also, the main pitch can be adjusted via external CV – sputtering noise, drones and basic rhythmic patterns are just a few things this little beast can provide…
