Oscillator

An oscillator is a module that generates a continuously repeating waveform, with its rate expressed as a frequency. That frequency determines whether the oscillator works as an audio source or a control voltage source. Frequencies above 20 Hz are considered audio rate, while slower rates are typically used for control voltage or as an LFO. The most common waveforms are sine, square, triangle, and sawtooth, each with its own harmonic content. Audio oscillators usually start the signal flow of a synth voice, while LFOs automate parameters on other modules.
