I have played some of the music on my keyboard that was played by you wonderful people on this forum, but I have a problem with volume sometimes. Most of the time the song plays fine with no problem. Ocassionally, a song will be playing along fine, and then all of a sudden, the volume goes way up for a few seconds, and then it comes down. This doesn't just happen once. It happens many times throughout the song. Is there something I can do to correct this in the song file so I can play the song through. It's a very beautiful song.
