What can Scaler Detector be used for?
Key, Scale and Chord Detection
With the same great key and scale detection as Scaler 3, the world’s favourite music theory plugin, Scaler Detector instantly identifies the key, scale, and chords of any track, loop, or live performance. Play in audio or MIDI in real time, or drag and drop files for instant results.
Try Out Chords and Experiment with Alternatives
Once you’ve detected the key and scale of a track, bind the notes for one-finger chords that fit perfectly with your music. Or simply search for a scale and start playing along. Enable Voice Grouping for automatic voice leading, making your chords sound richer and more musical.
