I love my SD1+.....I performing some of the best music I have ever played all around sounds & styles. People like Dan O, Prince AJ, Yahoo Ketron Forum, to mention a few are great places to ask for help which is always given.....besides the manuals........the only thing I would every consider in the future to add to what I have is the New Ketron "AUDYA"....when it arrives I'll be there to play one for sure!!

Good Luck
