Dual Low Frequency Oscillator
From MMM Wiki
Two independent LFOs in one module.
Each LFO contains two simultaneously available square and triangle waveform outputs.
Each output can be skewed to waveform extremes. i.e. square can be skewed from narrow-positive pulse widths through square to narrow-negative pulse widths.
Triangle can be skewed from positive saw through triangle to negative saw.
Each LFO has independent rate controls. The upper LFO has a lower range than the lower LFO
