Oh, I think I am understanding some things. If i name a part with "IN" that part is not repeated at end, otherwise the last loop it's played even if it is not part of the repeat barlines. I didnt think that I had to touch the player repeats, and with setting a x4 in the paper it would be enough, i wonder why not but i accept it.
The last thing I dont get is why in your example it sets a x4 and the final 4th end is the different, but in mine you had to set a x3, because there are 1 more.
Thank you so much for the help.
