An oscillator is an electronic circuit that generates a periodic waveform at a specific frequency. Oscillators are the fundamental building blocks of sound synthesis and are used to create the fundamental pitch of a sound.
Oscillators generate a repeating waveform at a specific frequency, which can be adjusted using a control voltage (CV) signal or a manual knob. The waveform can take on a variety of shapes, including sine, triangle, sawtooth, and square waves. Each waveform has a unique harmonic content and can be used to create different tonal colors and textures.
