ScaleSQ Tone Shifter

If you’ve heard about key and scale modulations, but aren’t quite sure how to apply these techniques in your compositions, ScaleSQ makes the process more intuitive.

Start by setting your home key and scale, then explore new harmonic directions with guided modulation suggestions based on proven musical principles. These include direct diatonic or modal shifts (e.g., C Major → D Dorian), parallel changes (e.g., C Major → C Minor), chromatic and circle of fifths modulations. With up to seven modulation slots, you can quickly shift between keys and scales — whether manually or via automation in your DAW.

What makes ScaleSQ unique is its ability to preserve melodic and harmonic relationships across modulations. Instead of rigid note correction, it maintains musical intent, making transitions feel natural and inspiring. Plus, with CV sync support, you can chain multiple instances together for synchronized modulations across your entire project.

Break free from static harmony and take your music to new places — effortlessly.
