The results are in - I contacted the dealer who in turn contacted General Music. They suggested clearing the memory, which I did. When I began sequencing again, the same thing happened (keyboard rebooted and the message "optimizing memory" came up). I then decided to reload the operating system. That still did not work. Another suggestion from the dealer was that perhaps one of the sounds I was using contained a filter which is taking up a tremendous amount of room. That's my next thing to try. Luckily, tonight I was able to complete the piece I was working on by saving it to a floppy disk every couple of measures - what a pain! I'll probably take a trip to the dealer next week with keyboard in hand! Thanks for your listening ear and suggestions - I'm glad I found this site.
