Dual Low Frequency Module
The LFO2 is a basic dual LFO module. It uses two different types of low frequency oscillator circuits to provide a variety of modulation options.
LFO 1 - A triangle based low frequency oscillator that utilizes rate and symmetry controls to generate shifting waveforms. Adjusting the symmetry control varies the shape of the TRI output from sawtooth to triangle to ramp, and also adjusts the pulse width of the SQR wave output.
LFO 2 - A simple triangle based low frequency oscillator with rate control over the triangle and square outputs.

These merchants probably sell this module. Huh?
