reTune

zplane reTune is a real-time pitch modification effect for reshaping the musical content of audio samples. Map individual input notes to any pitch in the chromatic scale, move a sample into a different key, or create unexpected harmonic variations with custom note mappings. For producers working with samples whose key is unknown, automatic key detection powered by zplane’s TONART V2 provides a useful starting point. Scale presets cover major, minor, church modes, gypsy and chromatic scales, while semitone quantization offers straightforward pitch correction. Adjustable detection sensitivity, transient handling and pitch contour smoothing help tailor how corrections respond to the material. Whether you’re matching sampled parts to a track or exploring more experimental pitch changes, reTune suits beatmakers and electronic music producers who want flexible control over sample tuning.
