I was wondering does anybody with a PA900 know anything about this set? It seems like it's an expansion pack but I don't know if the keyboard would require any additional upgrades or add on's to play these styles. I've tried to search where one could buy this pack but couldn't find anything. I would be something i'd certainly want if I had a PA900.

This comes in the form of a "dongle" - The product is on a micro card, which is placed into the Pa900 slot.
The cost is about $160 US I think.

Actually, the product is in a set that is actually downloadable. But you're right about the dongle, the set does not work without the micro sd card which needs to be inserted in the back of the keyboard.

Thank you for the replies.

So if I were to purchase this set, I could copy the files onto a universal MicroSD and it would work? Or is there such a thing as a proprietary Korg SD card?

No there is an authorization code imbedded in the MicroSD card they send.

Thanks Billy so I'd have no choice but to buy the SD card. That site you posted I wouldn't have a clue where to start as it's not in English and I can't find where to translate it.

The person who made all those styles and sounds is a very appreciated player and many many romanians that use Pa series particularly for Romanian traditional music will use his work.

This set was produced in partnership with the Korg representative for Romania, that is MCMusic.

I think the best way to proceed is by writing an email to them (bucuresti2@mcmusic.ro) explaining you're interested in buying the set and they will help. They are nice guys and very helpful.

If you think I can be of assistance to you, let me know.
