Thanks all of you for your kind answers! And I forgot to tell that he does have a "live" piano-teacher who comes to give him a lesson once a week. The problem for me is that after a day or so my son has forgotten some of the things in his homework and how it is supposed to be played, and I cannot help him enough, so that's why I thought that maybe by transferring the sheet music (his homework in paper form) to the computer via one of the Finale software, he will at least be able to hear how the piece should sound like, how you are supposed to count the rests, etc, and also be able to slow down the tune in order to have a better chance in the beginning to hit the right key and maybe to start out just with the right OR the left hand in order to lower the threshold a bit in the beginning! And it sounds as if I can do all this with BIAB and on top of it enhance the practice situation even further by "bringing in" a full orchestre into our living-room as a back-up band... I noticed that the version "Print Music" of the Finale software suite, has a scanning function which means that the transferring process will be sped up conciderably! Thanks once again!
