Interesting Idea. Love the Xlobby. I assume you grabbed the latest free version before the site went commercial? I have it running movies to my TV and a separate PC dedicated to music ( soon to be touch screen juke ). For piano software you might want to look at Rallentando software. I use it to slow down midi files for classical pieces, left hand right hand, etc. It even has a piano scroll if your not much for reading notes.
