## Description

Pick a key. Pick a scale. Sing. PitchLock pulls every note into tune as you sing — in your AUv3 host or straight into the app. One purchase, no subscription.

Sing it once, in tune. PitchLock listens to your voice and pulls every note onto the key and scale you pick — while you sing, not after.

Open the app and sing into your mic to hear it working in seconds. Then load PitchLock as an AUv3 effect in AUM, GarageBand, Cubasis, Loopy Pro or Koala Sampler and put it on your vocal chain.

HOW YOU USE IT
1. Pick a key and a scale — or leave it on Chromatic and let every note snap to the nearest semitone.
2. Set Strength and Speed: gentle for a take that still sounds like you, hard snap for the modern effect.
3. Sing. The keybed lights up the notes that belong to the scale, and the tuner shows the note you sang next to the note it corrected to.

WHAT YOU GET
- Real-time pitch detection and correction, with a Low Latency mode for singing through headphones while you track
- 54 scales, from Chromatic and Major to Harmonic Major, Persian, Enigmatic and Todi
- Strength and Retune Speed, from transparent polish to a full hard snap
- Humanize relaxes correction on held notes, so vibrato stays yours
- Voice Range presets — Soprano, Alto/Tenor, Low Male, Bass — lock tracking to your register for faster, steadier detection
- Formant Shift moves the character of the voice without moving the note
- Noise gate with an adjustable threshold, plus input trim, so room noise never gets tuned
- Fine tune in cents for sessions that are not at A440
- Key and Scale are exposed as host parameters — automate them or MIDI-map them
- A built-in tuner showing the detected note, the target note and the cents offset
- Full VoiceOver support: every control is labelled, adjustable and spoken
- One adaptive layout, from a compact AUM slot to full-screen iPad

MADE FOR
Tracking vocals at home. Rehearsing a part until it sits. Singing live through a phone or an interface. Cutting covers, demos, worship sets, rap hooks and choir stacks.

Whether you are rehearsing, recording or performing, PitchLock keeps every note in tune without changing your natural tone.

One purchase. No subscription, no account, no ads, no tracking. Audio is processed on your device and is never recorded, uploaded or stored.
