What Is Plugin Boutique “Scaler 3”? Differences from Scaler 2
Songwriting Support | Music Theory Workstation
Scaler 3 is a music theory workstation that makes harmony, composition and music theory visible, so you can turn ideas into finished songs quickly.
From your first chord progression to elaborate key changes, you can create chord progressions, generate melodies and basslines, build song structures and play your own instruments, all within Scaler 3. Because you can see the harmonies, scales and relationships between chords as you work, your understanding of music theory naturally deepens too.

Generating Melodies and Basslines
- Motions: a library created by musicians that turns chords into melodies, arpeggios, basslines and phrases. Mood-based tags make them easy to find

- Bass Follow Track: automatically generates a bassline that follows the root notes of the chord progression
- Divisi: finely control how chord voices are distributed, and send the upper and lower notes to separate Scaler instances for realistic ensembles and thick layering
Building Song Structure
