The Quadrature LFO is generating an sine wave and 3 phase-shifted copies of it:
by 90° (cosine), 180° (inverted sine) and 270° (inverted cosine).
The frequency of the LFO can be voltage controlled, the CV input is attenuverted.
You can use the LFO in a wider frequency range, from very low oscillations up to above the audio range. There is another CV-input, which let´s the LFO to be pitched by volt/octave, the tracking is quite ok over 2-3 octaves. A interesting possibility is to patch an output of the module to the Rate CV input, so you can create new waveforms that way while still controlling the Lfo by the V/Oct. Input. Using more than one module, you can create complicated and interesting output waveforms, up to pseudo-chaotic signals, escpecially, when 2 or more LFO´s modulating each other by pitch.
