Hi Dikki
All Wersi updates (Like the Korg OS3) are Free.
The only time you pay is when you have a very large upgrade, (Exactly the same as you get when you upgrade your hardware board to a new one) however it is still considerably cheaper then the price you have to pay to trade up your hardware board to a new one.
Enjoy whatever you play

Bill
