The Waves Key Detector Plug-In is a time-saving tool for all music makers, allowing you to replace manual work with AI-powered key detection for any sample, track, or full mix. Using Waves’ Neural Networks engine, Key Detector provides you with a root note, a scale (major or minor), and two likely alternatives. Key Detector is the perfect companion to Waves’ vocal tuning and harmonizing plug-ins: Waves Tune Real-Time, Waves Tune, Waves Harmony, and OVox. Just click the Transmit button, and the detected key will be sent to all active instances of these plug-ins.
