Scaler 3 is a comprehensive music theory plugin that builds on its predecessor by offering an intuitive workflow divided into three core stages: Browse, Create, and Arrange. The Browse tab enables users to select chord sets, identify fitting scales, and construct chord progressions with helpful suggestions rooted in music theory. It can detect audio and MIDI input to determine suitable scales, making it easier to explore new musical directions and expand creative possibilities.

In the Create tab, Scaler 3 provides extensive tools to refine and elaborate on chord progressions. Users can explore chord substitutions, alternative voicings, and modulation techniques to enrich their compositions. The plugin includes a rich library of Motions such as basslines, melodies, arpeggios, and strums, which can be customized with MIDI modifiers and note properties. Interactive features like the Circle of Fifths and the Explore page offer fresh inspiration for harmonic development and variation.

The Arrange tab allows users to perform progressions across multiple instrument tracks while hosting VST/AU plugins and effects directly within Scaler 3. This multitrack capability supports layering different instruments playing the same progression, enhancing production flexibility. With a vast collection of chord sets categorized by mood, artist, and genre, plus standalone operation and internal sounds, Scaler 3 is designed to help musicians solve musical challenges and bring their ideas to life quickly and effectively.
