Envelope Generatorenvelope-generator
762
LFOlfo
LFO with sine, triangle, pulse, sawtooth, and reverse sawtooth waveform outputs; frequency range 0.05–30 Hz with three range steps and external CV input.762

Jacks 5 — 3 in / 2 out

NameSignalVoltageDescription
Inputs (3)
Ext LFO triggertrigger≤10VConnect a trigger signal to turn the LFO off until the end of the trigger cycle. Works with the Delay slider; LFO recovery takes about 20 seconds. A rear panel jumper can be removed to prevent re-triggering.762
Ext gategate3V to 10V762
Frequency CV inputcv-10V to 10VCV scaling is 1V/octave for controlling LFO frequency.762
Outputs (2)
LFO OUT (inverting)cvLower jack; sends inverting LFO waveform output to other modules.762
LFO OUT (non-inverting)cvUpper jack; sends non-inverting LFO waveform output to other modules.762
