Tapping Soprano, Alto/Tenor, Low Male or Bass sometimes left the highlight on the old button ### 1.10.0 — 2026-08-30 What's new in this version: • New STRENGTH knob: dial in how hard correction pulls toward the note. Lower it and scoops, slides and bends keep their shape; raise it for a hard lock. Starts at 50%. • Formant now sits alongside Gate and Fine in the Input & Tune row • Fewer octave jumps on bright vowels — octave decisions now require corroborating evidence before they take effect • Wide melodic leaps commit faster, so big intervals no longer stall part-way through a phrase • Note: sessions and presets saved in earlier versions open at the new 50% Strength. Set Strength to 100% for the previous always-full correction. ### 1.9.0 — 2026-08-29 What's new in this version: • Fixed synthesis-period bug in overlap-add that caused level breathing on sustained notes • Voice Range refined: set your register and AutoTune stays locked on with fewer false octave jumps • Fixed Humanize buffer-size bug that could affect timing at certain host buffer settings • Localization for French, German, Spanish, Spanish (Mexico), Japanese, Brazilian Portuguese, and Chinese • Mac support • Tighter pitch tracking: fewer random octave or alien-pitch jumps during long sessions ### 1.8.0 — 2026-08-29 What's new in this version: • Voice Range: select your register (Soprano, Alto, Tenor, or Bass) and it locks onto your voice, dramatically reducing octave errors. Auto keeps the full-range tracking. • Fast runs and big jumps now track with much less lag, so even full-octave leaps snap to the new pitch quickly and accurately. • More consistent tuning across hosts: pitch correction stays stable no matter which host app you use or how its audio buffer is configured. • Fully localized: AutoTune is now available in French, German, Spanish, Japanese, Portuguese, and Chinese. ### 1.7.0 — 2026-08-14 What's new in this version: • Knob readouts update live while you drag ## More apps by NATHAN THOMAS MATHIS - [NAM AUv3: Neural Amp Modeler](https://appshunter.io/ios/app/nam-auv3-neural-amp-modeler/id6791673543) - [Chromatic Tuner AUv3](https://appshunter.io/ios/app/chromatic-tuner-auv3/id6791699061) - [Reverie: AUv3 Plate Reverb](https://appshunter.io/ios/app/reverie-auv3-plate-reverb/id6798475883) All apps by NATHAN THOMAS MATHIS: https://appshunter.io/developer/1870347850 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
