Jerry, I have used MPP's from the very earliest days and have never had any of them "freeze up". I've even dropped a couple of them and they just keep on "keepin' on". I use the edit and annotation functions extensively to put notes on my lead sheets, etc, and can change them at will. Feel free to post any questions here and we will do our best to help.

Playlists with the MPP work great, especially if you can pre-determine the list of songs that you plan to play. All you have to do is touch the right side of the display to call up the next song.
