Ha---me too! I tried another Roland drum machine, I forget which, and it featured bass and some other parts when all I wanted was drums. I could not turn them off and could not figure out the manual. I took it back to the store and they didn't know how to work it , so i swapped tor an Alesis. I have learned that Roland is quite good at making sounds and not so good at explaining things. Those first VS840 recoders had people yelling and throwing things when all they wanted was to do a simple recording. With Roland,simple is often not an option!
