Key Bump finds the key of any sample and bumps it into the one you want. Drop in a loop, vocal, melody or one-shot, hit Learn so it detects the original key without touching your audio, then spin the circle-of-fifths wheel to your target key — Key Bump pitches it straight into place.

Under the hood it runs studio-grade, transient-preserving pitch-shifting, so kicks stay punchy, basses stay solid and vocals stay human — no chipmunk, no smear. A dedicated formant slider keeps things natural or pushes them characterful, and fine-tune in cents gets you perfectly in tune.

Built for fast, harmonic sample flipping — DJ-style key matching for producers. macOS (VST3/AU, Apple-notarized) and Windows (VST3).
