Poly Square [ documentation | script ]
Six independent oscillators which output on CVs 1-6.
The base pitch is set by the analog input, which is interpreted as a V/oct input with 0V = C. Knob 1 allows for detuning of the 6 voices, and as the knob is turned clockwise, the spread between them increases. Button 2 toggles the maximum detune between a half step and a major 9th. Knob 2 sets the polyphony mode.
