I went to add an older SMF to my playlist and found that only the drums played - channel 10. The other channels were firing but I was getting no sound. I have a few of these that I now remember will not play properly on Yamaha equipment. They will play on my Roland and my Power Tracks and Media Player.

I remember a discussion years ago about a SYSEX message that needs to be added or deleted, but heck if I can remember or find it. Can anyone help me get these files to play on my s950?
