2OPFM is a digital 2-operator FM voice in 6HP. It features 2 sine wave oscillators and a decay envelope to control their amplitudes. Perfect for growling percussion and plucky melodies.

Envelope: The length of the internal decay envelope. The associated jack is an offset to the slider.

FM: The amount of FM modulation of the carrier. The associated CV input is an offset to the slider.

KHz: The base frequency of the carrier oscillator. The associated CV input is an offset to the pot.

RATIO: The ratio of modulator frequency to carrier frequency.

OP1: The main output.

TRIG: A rising edge triggers the built in decay envelope. This envelope modulates the amplitude of the carrier, as well as the modulator (at a slightly faster rate) Incoming triggers are ignored when the envelope is active, thus allowing for frequency division based on the decay slider.
