My right speaker is currently not working at all. I am also unable to play MIDI files.
Bell-Solton (US distributor) has informed my dealer that a user's video is being produced. MIDI playback worked when I first got the X1, but I may have changed some setting that disabled it. My three hours troubleshooting using the manual didn't help so I am waiting to give it a try with the video. I am also having other problems. I can live with all the problems because I am using the X1 as a MIDI module triggered with an accordion. I use external speakers only. But, I do expect to have all the problems taken care of under warranty and will start pushing when I lose patience. I have had such good audience reaction to the X1 I would hate to give it up.
