Thanks a lot for the replys ! I have checked my midi studio but the keyboard doesn't appear. I have downloaded snoize and it shows that the wordclock is shared as well as the key pressed infos. By un-assigning the HUI, i've managed to make sound enter to structure. But it only send the impulse of the signal. It can send impulse but not keeping the note on.
I think the issue is with the midi configuration. However i've tried different settings directly on the xs8 and it didn't work. I'm not shure that i'm on the new firmware so i'll try to update and i'll keep you informed. If you know how i can make the midi editor to detect the motif, i wait your advices !
Thanks a lot :)

EDIT : I managed to get into midi configuration correctly (thanks sierra !) and the motif is seen when pluged in. However i still have the same problem in protools.
