Kawai K3/K3m Editor and Librarian

Kawai K3 & K3m patch editor and librarian — it runs in your web browser.

A tool I built to edit and organise sounds on the Kawai K3 and K3m hybrid synthesizer.

Tweak every parameter on screen, pull single patches or whole banks off the synth, back them up as sysex files, or load sysex files from your computer and into the hardware.

I added a little on-screen keyboard too, handy if you're using the K3.

It runs in a web browser (Chrome or Edge — not Firefox or Safari) with a MIDI interface connected to the synth. It works on PC and Mac, and under Linux.

It's my personal tool shared for anyone who wants it. Setup instructions come in a short readme with the file, but I offer no support on this. It's shared "as is".
