Auto-Key 2 is a music analysis plug-in designed to speed up essential production decisions: identifying the key, scale, and tempo of a track or sample. It is aimed at beatmakers, sound engineers, and producers working with loops, samples, instrumental recordings, or stems who want to save time during harmonization, transposition, and vocal tuning. Ideal for locking in a topline, tuning a bass, choosing coherent chords, or preparing a pitch correction session without guesswork.
Auto-Key 2 automatically detects key, scale, and tempo from your audio, allowing you to quickly make consistent musical choices. Whether working on a demo, an advanced production, or a remix session, you get a clear readout of harmonic information to avoid "off-key" notes and speed up adjustments.
To analyze a file, simply drag and drop it into the interface: convenient for testing multiple versions of a chorus, comparing samples, or checking the key of a loop before slicing it. Auto-Key 2 supports common studio audio formats, making it a fast tool to organize your library and work cleanly from the start.
The "Send to Auto-Tune" button automatically updates compatible Auto-Tune versions with the detected key and scale settings. The result: you avoid configuration errors, save time on settings, and achieve more consistent vocal correction from the first listen.
Designed to integrate with all major DAWs, Auto-Key 2 fits easily into an existing session. It helps to streamline and automate repetitive steps related to key detection and key changes throughout a track, allowing you to focus on arrangement, sound design, and performance.
