MetaPitch: Vocal Pitch and Formant Shifter by Slate Digital

MetaPitch is built around pitch and formant shifting, so you can change the pitch of a vocal and adjust its formant independently of it. The built-in Drive and Widener controls add color and dimension to the processed sound, and high- and low-pass filters let you shape the result within the same plugin.

The developer describes Robot mode as a way to draw custom melodies via MIDI, applying a vocoder-type tone to the source signal. This gives the plugin a character beyond natural pitch correction.

Grouped instances let you apply the same processing parameters across multiple tracks at once, which is useful when several vocal or instrument tracks need matching treatment. Multiple channels can be edited together in the same way.

Low Latency Mode reduces the delay you might hear while recording, which can otherwise distract a performer. For maximum quality while mixing, you can switch Low Latency off.
