Summary: I liked this keyboard cause it sounded good for the price. If you play a midi file through the USB slot it will look like its playing but not produce any sound. When you play around a bit you usually Get one instrument out of 16 to play. It seems that this keyboard does not have any abiity to disable or enable parts on a midi file. Also there is no background styles to play with only stupid pop or rock beats just drums you can't play with it like on the Yamaha keyboards.
