LFO

Low-frequency oscillator for modulation duty. Same waveforms as the audio Oscillator, plus an output depth scaler.

Inputs

NameTypeDescription
frequencycontrolFrequency CV in Hz. Adds to the rate set by the `period` parameter (1/period).
depthcontrolDepth CV. Adds to the `depth` parameter; controls output amplitude.
pwcontrolPulse-width modulation, 0–1. Audible only on the square waveform.

Outputs

NameTypeDescription
outcontrolModulation signal, scaled to ±depth.

Parameters

NameTypeDefaultRangeUnitDescription
waveformenumsinesine, square, sawtooth, triangleModulator wave shape.
periodnumber10.01–100 (log)sCycle length in seconds. Inverse of frequency.
depthnumber1000.001–10000 (log)Output amplitude. Scales the ±1 oscillator into target-parameter units (Hz, cents, V/oct, …).
pulseWidthnumber0.50.01–0.99Duty cycle of the square wave.
