Unlike standard audio oscillators that produce sounds within the range of human hearing, an LFO operates as a control signal generator. These processes are fundamental to creating expressive and dynamic patches.
Low Frequency Oscillator Signal Routing Strategies
The oscillator produces a repeating waveform, typically a sine wave, triangle wave, square wave, or sawtooth wave. Tempo Sync: Locks the LFO rate to musical note values (e.
Triangle/Sawtooth Wave: Produces a linear, ramping effect, perfect for phasing, chorus, or arpeggiator-style modulation. Chorus and Flanging: An LFO modulates the pitch of a delayed copy of the audio signal, creating the characteristic whooshing, jet-like textures.
Low Frequency Oscillator Signal Routing Strategies
Phasing and Auto-Pan: LFOs are used to shift the phase of the audio signal or to pan the sound automatically across the stereo field, adding width and motion. , 1/4 note, 1/8 note), making it an essential tool for rhythmic design.
