NameSignalVoltageDescription
Inputs (3)
Rate CVcv0V to 5V375
Reset InputtriggerResets the phase of both LFO outputs.375
Wave CVcv0V to 5VControl voltage added to the Wave Knob position for waveform selection.375
Outputs (2)
Primary Waveform Outputcv0V to 5VOutputs the primary waveform (Cosine, Triangle, Saw, Square) with LED brightness corresponding to output voltage.375
Secondary Waveform Outputcv0V to 5VOutputs the secondary waveform (FM Sines, Inverted Triangle, Ramp, Stepped Triangle) with LED brightness corresponding to output voltage.375

Parameters 3

NameTypeRangeBehavior
Range Toggle SwitchswitchSelects between two LFO rate ranges: Left position gives 27 sec to 20 Hz; Right position gives 3.3 sec to 152 Hz.375
Rate KnobknobControls the rate of the LFO. Range depends on Range Toggle Switch position.375
Wave KnobknobSets the waveform for both outputs. Interpolates smoothly between all 4 waveform positions. Primary output: Cosine, Triangle, Saw, Square. Secondary output: FM Sines, Inverted Triangle, Ramp, Stepped Triangle.375
