If I upload an XML-File of my guitar music nothing appears normal. It does not recognise that it is a "guitar" and there is a horrible piano sound. I can edit that, but the "guitar" sound is a piano then. Not really usable. All the repetitions are not played. Did anybody find out why or is this just my problem? There are several other problems, but I would be happy if the repetition problem would be solved. Any idea?
