Scaler Music Scaler Detector v1.0.0-TCD

Scaler Music Scaler Detector is a key, scale and chord detection utility for producers who want to understand the harmony in their music without working everything out by ear. It analyses audio or MIDI to identify chords and determine a musical key and scale, then suggests compatible chords to help you explore what could come next.

You can use it with a complete song, an individual polyphonic audio track or incoming MIDI notes. That makes it useful when checking the harmony of a recording, identifying chords in a part you have played, or looking for a starting point for an accompanying progression. Guitarists moving into keyboard-based production and hobby producers with limited music theory knowledge may find this approach particularly helpful.

This Windows version includes standalone operation alongside VST2, VST3 and AAX plugin options for compatible hosts. In FL Studio or Ableton Live, Scaler Detector provides a practical way to investigate harmonic material and find related chord ideas while developing an arrangement.
