Thanks for your reply. But I'll need load new samples for exchange old voice.
I know about user voices, but it is the same internal piano. I would update like on PC computer or "Flash" some of internal voices.
Thank again for your advice.
Take Care: Mariusz.

Editing features are not that great on X1 sounds, but depending on what music you want to use that piano for, I have made some nice pianos on mine.
