# Osc Node

The Oscillator node is the foundation of most synthesizers. It produces one of the following waveforms, according to its waveforms menu:

- sine. A neutral waveform with no harmonic character.
- triangle. Also mellow but with more harmonics.
- square.
- sawtooth.

To see what these waveforms look like, set the oscillator's pitch input to 1 and attach the out output to a waveform node.

The pitch input is in units of Hertz.

The sync input will reset the oscillator whenever it crosses 0. To see this in action, hook another low-frequency oscillator to the sync input and watch the waveform node.

The semitones and cents knobs shift the input pitch.
