how can i do i have try to load first one compleet set and than i just load the user 1 but i dont have than the sample or and i have try-ed to load the PCM but it's not working
There is no satisfactory solution at the moment to the problem you have described. It is only possible to load ONE .set file containing styles that point to user sounds. (ie contrary to the advertising that describes capability of hundreds of user styles and user sounds to be loaded). If you load a second .SET file containing styles and user sounds, then a failure occurs due to broken linkages from the style to user sounds. The original sounds will be overwritten when you load the second .SET file. And if you try to relocate the sounds from the second .SET file then the styles in that .SET file won't play because of broken links to the sounds. In my opinion, you should write a letter of complaint to your dealer and ask you dealer to forward the letter to Korg Italy. There may also be a case you can make about mis-advertising and breach of trading standards in the product description for your keyboard.
I acknowledge Nedim's writeup on how to manually resolve the broken links problem. With respect, this level of complexity is well beyond the limits of endurance for any musician.
