01What it does
Scales
Major, natural minor, harmonic minor and Hijaz, with your own harmony note for every note of every scale.
Harmony parts
Upper 2 and Upper 3, each playing above or below your note on its own MIDI channel.
Key changes
Play a chord to set the key and scale. Your left-hand chords never move it.
Connection
A USB cable from the Pa5X. Phones work from any of its USB ports; a Windows PC needs the USB DEVICE port and Korg's free driver.
Runs in
Chrome on Android, or Chrome and Edge on Windows. Nothing to install. Chrome and Edge on Mac and Linux should also work, but haven't been tested with the Pa5X yet.
Won't run on
iPhone, iPad or Safari. Apple's browsers can't talk to MIDI keyboards.
