I've done some searching on the board and could not find what I was looking for so I figured I would toss the question out there. I am using a Yamaha PSR-290, which comes already loaded with about 100 songs which have the "lesson" feature on them. You can practice the left and right hand parts seperate from each other. I think these are called XG Midi files, but I am not sure. What I am wondering is this: where can I find some more of these kinds of files with the "lesson" option? I'd really like to use this feature to learn how to play some current songs, but I can't find them anywhere. Is there a way to sequence MIDI files so that you can separate the left and right hand tracks for the "lesson" purpose? The user's manual of my PSR-290 (on page 76 - Function Section) has a section called "Lesson." It states that by pressing the "Function" button and selecting either "Lesson Track (R)" or "Lesson Track (L)," you can: "determine the track number for your right [or left, respectively] hand lesson." I am wondering what "track number" means. You have the option of selecting a number from 1-16 to set the "track number." I am assuming that this does not work for most MIDI files sequenced by amateurs. Can anyone shed some light on this subject? Specific questions: 1. What is the difference between XG MIDI files and regular ones? 2. Where can I find these XG "lesson" style MIDI files? 3. Is there a way to somehow convert an amateur-sequenced MIDI file I downloaded off of this forum into a format that will allow me to use this "lesson" feature (seperate right and left hand parts)? Thanks in advance for any help you can give me. I know Newbies are annoying sometimes. I did my best to find this info on my own, but now (4 hours later) I am exhausted of scouring the web and this board. I tried to be as detailed as possible with my question, so as to avoid any confusion. I appreciate any help you can give.
