Scaler Detector Key Features

Detect Keys, Scales and Chords from Audio or MIDI

With powerful detection technology, Scaler Detector identifies chords, determines the key and scale of your music, and suggests chords that fit perfectly.

Drag and Drop. Record, Play

Drag and drop any MIDI or audio file straight onto Scaler Detector for instant results. When you’re done, simply drag and drop the detected chords straight to your DAW, your desktop, or anywhere you like.

See What You Play in Real Time

Watch notes and chords appear instantly as you play on your MIDI keyboard, displayed clearly in the Chord Panel for quick reference and feedback.

Work within your DAW or in Standalone Mode

Load Scaler Detector as a VST, AU, or AAX plugin inside your DAW, or run it in standalone mode. No DAW required – ideal for focusing on music theory, composition, or harmonic experimentation.

Enhance Harmony with Voice Grouping

Instantly transform basic diatonic chords into richer harmonic results while keeping everything musically cohesive.

Play with Scaler’s Bind to Keyboard

Trigger chords with one finger from your MIDI controller, perform progressions over detected music, and make playing fast, fun and intuitive.

See Scale Notes on the Keyboard
