Pi Tune
Every note. Every maqam. Zero latency.
Real-time vocal tuning built for the stage. Pi Tune corrects pitch with no added latency and speaks the scales the world actually sings — Western modes, Arabic maqamat, Turkish makamlar, Persian dastgah, Indian raga and more.
Music was never only twelve notes. Pi Tune hears the quarter-tones your singer means.
What it does.
Zero-latency engine
Pi Tune reports zero samples of plug-in latency, so it sits on a live vocal without pushing the singer out of time with the band.
The world’s scales
Ten scale families: Western, modes, jazz and bebop, exotic and synthetic, Indian thaat and raga, East Asian, African and Indonesian, Arabic maqamat, Turkish makamlar and Persian dastgah — quarter-tones included.
Learn the key
Let Pi Tune listen to another channel — keys, guitar or a side-chain — and learn the key and scale automatically, with bleed rejection for live stages.
Snapshots on cue
Store key and scale snapshots and switch them per song by MIDI or SMPTE timecode, so the tuning follows the setlist.
Natural, or not at all
Retune speed, humanize, flex-tune, vibrato, transpose, detune, tracking and mix — from invisible correction to the hard-tuned effect.
See every note
A live display shows input, corrected and target pitch against the active scale, with a scale keyboard you can edit by hand.
Built for the monitor world.
Pi Tune was designed for live vocals first: zero latency, fast voice detection and bleed rejection mean it behaves on a loud stage, not just in a quiet booth.
Quarter-tones, respected.
Choose Rast, Bayati, Hijaz, Saba and the other maqamat — or makam and dastgah — and Pi Tune targets the real intervals of the tradition, including notes between the piano keys.
