Pivotuner is a real-time MIDI tuning plugin designed to deliver pure intonation, enabling musicians to create perfectly tuned chords and explore unique microtonal modulations. Unlike standard equal temperament tuning, which divides an octave into 12 equal parts, Pivotuner allows for more precise pitch adjustments that align with natural harmonic ratios. This results in chords and intervals that sound more resonant and harmonious, expanding the creative possibilities for keyboard players and composers.

Inspired by innovative arrangements that utilize microtonal modulation, Pivotuner brings these advanced tuning techniques within reach of a broader audience. The plugin works by defining pivot notes—central tones within chords—to which all other notes are tuned according to pure intervals. This approach enables smooth microtonal shifts and complex modulations while retaining the familiar 12-note framework. Users can also lock keys or pitches to control modulation effects, allowing for both traditional and experimental harmonic textures.

Pivotuner offers extensive customization options, including multiple tuning algorithms and the ability to select from different interval tuning methods, enhancing creative flexibility. Whether aiming to achieve perfectly harmonized chords or to experiment with unusual sonic landscapes, this plugin provides a powerful toolset for musicians seeking to push beyond the limitations of standard tuning systems. Its combination of precision and adaptability makes it an essential addition to any modern MIDI setup.
