Does the QS7 have a built in sequencer,and a floppy discdrive,somoene recomended this keyboard but I havent had a chance to see it,do you consider it to be a good choice,how is the piano sound,thanks a lot

The QS7 doesn't have a built in sequencer, it comes with a computer sequencer on CD, Cubasis I think. Nor does it have a floppy disc drive. It's meant to be used with a computer sequencer. I don't own one but the general feeling about Alesis synths is positive, but I have seen some people complain that the piano lets it down. However it's better than the QS6 piano. Hope this helps.
