Automatic Key, Scale, and Tempo Detection
Auto-Key 2 is the automatic key, scale, and tempo detection plug-in which easily identifies primary musical properties to assist music creators and speed their workflows.

By automatically updating the key and scale of all the Auto-Tune effects in use, Auto-Key will drastically improve your workflow and boost your productivity. However, it does much more than finding the correct key and scale for your music. Auto-Key detects the key and scale of a track outside of your session in seconds, which is ideal if you're a DJ looking for tracks in the same key. Furthermore, the pitch reference display and the Detune control will allow you to adjust the pitch reference based on the deviation from the standard A440.

Effortless Analysis
Scan your music in real-time and detect key, scale, and tempo information automatically from any audio file.

Drop It Like It's Hot
Drag and drop audio files directly into Auto-Key 2 for easy detection of key, scale, and tempo information across all Auto-Tune plug-ins.
