To my knowledge everything works but one button needed to be pressed a little more but surely still works but other then that, I don't see anything else, excellent keybed use it as a keyboard controller or use the powerful speaker system with 70 watts of power.
This original cost when it first came out was over 5,000 Dollars from what someone told me and I never saw a WERSI product that was cheap which is in fantastic condition throughout. The sounds are amazing which include many pianos, piano pads, authentic strings, organ sounds, they're all there. This keyboard is getting harder to find now as people are holding onto them more. The touch screen is a real plus, with Intro/start, drum fills, variations & endings, they sound so realistic. The drum patterns sound as near to a real drummer as I've ever heard. The built-in 4-way speaker is beefy enough to fill any room, 70 watts with its clarity & beefy bass. Take the audio outs to a sound system and you've got a professional keyboard that you can take on the road. Don't just take my word for it- check out the demo's on Youtube:

it was a trade so I don't know anything about it other then it plays just fine, this one is extremely heavy (German- built)! Includes manual and power chord. This is heavy so I will pack well if you want it shipped.
