Hi,

Thanks for your advices. I have not post an answer because I was not at home but at gig ... but not with Audya, not the time to look at my problem (I take my old Roland A70).
Today I'll try to connect my Audya with USB and delete the corrupted .INS file. (thanks to Audyaplayer for the F1 function).

Many thanks for all (and sorry Dusan to have not be able to answer earlier ...).
