The product
Editorial respect for the Kronos.
Kronos 3 Editor talks to your Kronos 3 over USB-MIDI using Korg's own SysEx protocol, with no extra hardware. Edit programs and combinations with everything laid out at once, organise and back up your banks, and never lose a sound to a touchscreen menu again. Read-first and safe: it reads and verifies before it ever writes.
Full on-screen editing
Every parameter of a Program on one deep, fast panel (oscillators, filters, effects, and routing), across all nine Kronos engines, instead of paging through the hardware's screen. Edits round-trip to the Kronos 3 live.
Combination editor
Open any combination and shape all 16 timbres on a mixing-desk layout: program, status, Play/Mute, Solo, pan, volume, and an activity meter per timbre, with each timbre's key and velocity zones on an 88-note keyboard that lights as you play. Edit its Vector, controllers and scale, and its effects live, then Store the whole combi back to a USER slot with the same read-back-verified write as programs.
Prog/Combi browser
Find any sound from one window: browse and switch every Program and Combination, filter the whole Kronos by category just like its Category Select (with your own renamed categories), and see programs and combinations side by side in one list. It follows the hardware dial in Program and Combi mode, favourites for both are written safely back to the unit, and the browser widens with the window so a whole bank fits on a big display.
Set lists, your way
Build and rearrange a whole show, colour and comment every slot, then Write it back to the instrument. See a set list as a full-width list or in a 4x4 grid that matches the Kronos's own paged view. A light theme with a per-project dark/light switch, and recall-on-open that puts the Kronos back on the right sound when a DAW project loads.
Librarian, backup & formats
Pull whole banks off the unit, search and rename sounds, mark favourites, and keep unlimited libraries on your Mac as .syx files (a combination .syx reopens in the combination editor). Runs as an Audio Unit, a VST3, and a standalone app.
Now on iOS
Now on iPad and iPhone.
The editor, native on iOS: edit programs across all nine engines in Flow or Classic view, shape effects with all 16 slots on screen, build and store set lists, and browse and back up your library as standard .syx files, over USB or network MIDI. Sit an iPad on the Kronos and it becomes the second screen the hardware always deserved.
Sold separately on the App Store. The macOS app and license are unchanged; the iOS app is its own purchase through Apple.
Inside the editor
Built around how you actually work.
A read-first design that observes and verifies before it transmits, so it is safe on a real instrument. It edits Programs across all nine engines and every program's effect chain, edits Combinations (all 16 timbres, their zones, Common settings and effects), edits and stores set lists, manages and backs up your library, and browses and switches both Programs and Combinations from one window. Within a combination, KARMA, the Drum Track and audio-input routing are not editable yet, and there is no Global editor. More may follow in future updates, shaped by what players ask for.








Want to see it on your own Kronos 3? Download and install the editor, and it runs as a fully functional 7-day trial, with editing and writes to your Kronos enabled. After 7 days it drops to read-only (you can still connect, pull, and browse) until you activate with your license key. One license covers two computers.
