An oscillator is a module that generates a continuously cycling or looping waveform, with the cycle rate commonly expressed as a frequency. This frequency determines whether the oscillator functions as an audio or control voltage source. Frequencies above 20 Hz are considered audio rate, while those below are typically used for control voltage or as an LFO. The most common waveforms generated by oscillators are sine, square, triangle, and sawtooth waves, each distinguished by its harmonic content. Audio oscillators are usually used as the starting point for the signal flow of a synth voice, while LFOs are employed to automate parameters on other modules.
