Hello Jodi,
THANK YOU for your very quick answer! Nice reactivity ! So I will quickly inquire about this "Air turn duo BT 106" it seems a bit expensive, but I trust your advice, if it is easy to use and reliable ... it may be worth the investment!
I'm also looking for a tutorial (in French) or help to use sheet pro that I just bought; I scan my scores in PDF and I send them on my tablet...then I don't know how to put several pages in a row, or delete a score, or classify by categories (paso, waltz..) or create a repertoire with a chosen order to play these pieces in a row, during an evening. In short, I have everything to learn! Thank you again for your help and have a nice day.
