The sounds in the QY100 are all XG sounds, so you loose the great quality "panel" voices in the PSR keyboards. Also, you can only play 3 finger chords if you want to use a midi controller to play auto accomp. The good thing about the QY100 over the QY100 is the addition of a foot pedal option so you can move from variation to variation (2) or you can use it for starting and stoping the styles. The QY100 also has a mic or guitar input and a seperate effex processor for this input. As for the styles, there are less jazz, latin and ballads than on the PSR keyboards. Primarily, this product has more rock, techno and more modern styles. There are over 4,000 phrases from which to make up the 8 tracks of the styles and you can program your own tracks from scratch if you like.
