Hi all, just like to say hello. I am a beginner, only been playing about 5 months. I had a Casio keyboard someone gave me and I got hooked on playing it so much that I bought a Yamaha PSR s550b keyboard and it is so much better. I was wondering if I could load mp3 files on a flash drive and install them in my keyboard to play along with? I looked in the manual and it didn`t say anything about mp3`s, just MDB files and MIDI files. Also can I convert MP3`s to MIDI? I don`t really understand this. Any info would be appreciated. Thanks Rob
