When ever I use the playback on my computer, it will play, and then suddenly cut off. If I bring up "Monitor Out" and just lightly touch the wave fader slide, it immediately springs to life, and continues for a few seconds more, and does it again, When I "first" bring up the board that displays these fader slide controls on the monitor screen, the one that says " Monitor Out, Wave,Swsynth, and CDplayer, the Wave is always at the off position, until you slide the Wave fader knob up. It always drops to the off position until I play another song, and it does it again! This is truly aggravating, Help!!!!
