Kevin, Thanks for the info, I downloaded the upgrade and it loaded fine. I got my Boss 1600CD last week and I'm still scratching my head over the manual. I can do all of the recording, etc. but the drums are defeating me at the moment. I seem to get half way through the song and the drums stop. Not sure I really understand what's going on. The manual is fine at telling you what the parameters do but not why you might want to use them. Are there any tutorials you are aware of?
