An oscillator is how synths generate sound. It is a single-cycle waveform that is looped to match a specific pitch. This pitch is usually determined by what key you play on your MIDI keyboard. If you play an A4(440 Hz) on a MIDI keyboard that is triggering a synth, the oscillator will loop fast enough to mimic the pitch of A4.
