We don't have a drummer so I do use the style patterns with no auto accompaniment, just the drum patterns. The drums sound great on Ketron instruments. We perform for dancers. Swing tunes, fox trots and a few waltzes and a lot of latin dances. I also play the bass lines.
The SD-7 is a marvelous instrument and is really well designed. It is very intuitive to operate but I have a lot of experience with all makes and models of keyboards. I'll take the Ketron SD-7 over anything on the market today.
