What is PA SET Explorer?#

PA SET Explorer is a Windows program that lets you open, explore, combine and convert the SETs of KORG Pa arranger keyboards — and of the Medeli AKX / Zen expansions — on your computer, without the keyboard.

A KORG SET is the folder your keyboard saves to a USB stick: it holds your styles, sounds, samples, pads and performances. Normally you can only see what is inside on the keyboard itself, one screen at a time. PA SET Explorer shows you everything at once, lets you listen to it on your PC, and lets you move things between SETs with your mouse.

Think of it as a file manager made for musicians: you open your SET, you see every style and every sound, you drag what you want from another SET, you press Save and you copy the SET back to the keyboard.

What you can do with it#

Supported keyboards and files#

PA SET Explorer works with the whole KORG Pa family that uses SET folders, plus the PA5X with its new KST format. When you open a SET it asks which keyboard it is for, because each model has a different amount of sample memory:

KeyboardWhat you openSample memoryCompressionStyles per bank
KORG PA300a .SET folder32 MBNo40 (5 pages × 8)
KORG PA600a .SET folder96 MBNo40 (5 pages × 8)
KORG PA900a .SET folder192 MBNo40 (5 pages × 8)
KORG PA3Xa .SET folder128 MBYes40 (5 pages × 8)
KORG PA700a .SET folder128 MBYes48 (6 pages × 8)
KORG PA1000a .SET folder600 MBYes48 (6 pages × 8)
KORG PA4Xa .SET folder1.5 GBYes48 (6 pages × 8)
KORG PA5Xa .KST folder2.5 GBYesfolders of .stg styles (10 per page)
Medeli AKX / Zenan AKX set folder (with a .GSTarget file)256 MB or 768 MB—packs of styles
“Compression” means the keyboard can store samples compressed, so more of them fit in memory.

The first time you open the program#

  1. 1
    Choose your language

    The very first time, the program asks for the language of its menus. Pick one and press Continue. You can change it later with the globe button at the top.

    PA SET Explorer
    Select Language appears automatically on the first start.
    1. 1The list of languages. English and Español are complete.
    2. 2Press Continue to confirm.
    Select Language appears automatically on the first start.
  2. 2
    Read the Beta notice

    PA SET Explorer is in active development. A short notice reminds you to keep backup copies of your SETs. Press I understand.

  3. 3
    Activate your license (if asked)

    If this computer has no license yet, enter your license key. You find it in your profile on the website. A trial license also works.

  4. 4
    Open a SET and choose the keyboard model

    Press Open SET/KST and pick your SET folder (see Open SET/KST). When it has loaded, the program asks which keyboard the SET is for. Choose your model — this sets the memory bar and decides whether sample compression is offered. A PA5X KST is recognised automatically.

    PA SET Explorer
    Select Korg Model — the choice is shown at the top of the window afterwards.
    1. 1Every supported model with its sample memory and whether it can compress samples.
    2. 2Click your keyboard, for example PA4X.
    3. 3Skip if you only want to look around — you can still explore the SET.
    Select Korg Model — the choice is shown at the top of the window afterwards.
    Choose the keyboard the SET will be played on, not where it came from. A SET from a PA4X that you want to load on a PA1000 should be opened as PA1000, so the memory bar warns you if it is too big.

A tour of the main window#

This is the program with a real PA4X SET (“Stefan v2 2021”) loaded. Learn these 12 parts once and you will find your way everywhere:

  • If something keeps playing, press Stop at the top right.
  • Hover any button for a second: most of them show a small explanation (tooltip).
