I've been using a Tascam 244 for several years now. Never had any issues I haven't been able to fix. Sounds great. Lately though, I've been having a strange (not terrible, but frustrating) problem. I will have multiple recorded tracks, and when I go back to listen to them, one of the tracks doesn't play. If I simply turn the machine off and back on, everything is fine. It has begun doing this very regularly on playback - to the point that I've started automatically turning it on and off before listening to playbacks. Never effects recording, and no other problems. Any thoughts or ideas? Thanks.
