🎉 StepPolyArp celebrates 15 years!

To mark the occasion, I’ve created a 15th Anniversary Bundle featuring StepPolyArp, ChordPolyPad, QuantiChord, and MusicMath in a single pack, available for a limited time from September 25 to October 25, 2025.

If you already own some of the apps, the bundle price automatically adjusts.

Discover it now and explore all the tools to compose, experiment, and bring your musical ideas to life.
