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.
