A browser-based harmony tool for the Korg Pa5X that adds fixed-key harmony to a right-hand solo.

Landing page captured for the 2026-10-15 issue.

For: Korg Pa5X players seeking fixed-key harmony
Worth noticing: It supports four named scales and per-note custom harmony notes, while explicitly excluding iPhone, iPad, and Safari.

Field notes

The page names four supported scales—major, natural minor, harmonic minor, and Hijaz—and allows a custom harmony note for every note in each scale. On Windows, it specifies the Pa5X USB DEVICE port and Korg's free driver; Chrome and Edge on Mac and Linux are described as likely to work but untested with the keyboard.
