Connect a MIDI device, keyboard module, sequencer, pitch detector, LFO, or any CV source to select the frequency or note the oscillator will play. You can modulate the frequency or pulse width with the optional parameters. Negative CV inputs (from -1 to 0) will generate sub-bass frequencies between 0.027Hz and 27.49Hz. Be careful!2*FM inputno modifier allows you to connect another oscillator or audio source to modulate the oscillator's frequency. oscillator outputs, audio inputsfm intoggles presence of FM input parameter. this allows you to modulate an incoming audio signal against the oscillator, which acts as a carrier wave.
