An octave effect generates notes one or more octaves above or below the input. Analogue circuits often create raw monophonic sub-octaves, while digital pitch tracking can follow chords and provide several intervals with cleaner separation. Tracking speed, polyphonic accuracy, latency and the balance of dry, upper and lower voices determine whether the result feels tight, organ-like, synthetic or deliberately unstable.
