# Transposer

The Transposer effect shifts the pitch of the audio signal by the amount set by the Semitones and Cents knobs. Pitch can be shifted up to one octave up or down. The Transposer features two programs: Monophonic and Polyphonic.

### Monophonic

The Monophonic program is optimized for monophonic ("one note at a time") audio. It features a Formant knob, which shifts the formant of the sound. Pitch shifting sounds most natural if the formant is shifted in the opposite direction (e.g., if pitch is shifted up 2 semitones, the formant should go down 2 semitones).

### Polyphonic

The Polyphonic program is optimized for polyphonic audio. It is extremely CPU-efficient while still producing good results. Part of the efficiency comes from a limited headroom, which is where the Level knob comes in. If the light above it turns on, the audio signal is clipping and you should turn the Level knob down a bit. This typically won't happen, but it may if the signal has been amplified by other effects. If a track has been recorded at a very low level, you can turn up the Level knob to maximize sound quality.

Note: the Transposer only works if delay compensation is available. In short, this means it does not work "live" using Soft Monitoring.
