oh whell..after one week I can resolve the problem, but it seems a little strange how.
I just couldn't save the volume changes (es.track 4 to volume 0), because the mute saving doesn't work,and the transpose saving neither..I've played with ketron x1 3 years and now with xd9 two months before annoying you with my troubles..I just re-install the new operative system ,But the first time nothing happened ,the second time all ok for two days ,and now (I hope) after the third time all works good!Bah!
Thank you guys..
