What Scaler 3 is
Scaler 3 is a paid music composition workstation for exploring harmony, arranging ideas, and learning music theory. Its library contains more than 1,000 chord sets, keys, and modes grouped by mood, artist, and genre. The software detects chords, keys, and scales from MIDI or audio and suggests compatible chords. Reverse chord lookup, a progression generator, voicing exploration, and chord playback support different harmony workflows. The Arrange page places chords, melody, bass, and phrases on synchronized timeline lanes with adjustable clips. Scaler 3 can host third-party VST and AU instruments and effects, or route MIDI to external instruments and plugins. Listed DAW compatibility includes Ableton Live, Pro Tools, Logic Pro, FL Studio, Cubase, Studio One, Bitwig, Reaper, and Reason.
