If the key contacts are failing, how is this in any way the fault of gigging it? Moving it around doesn't stress the keys, PLAYING it stresses the keys.

Are you suggesting that it just needs to be played less, and everything will be fine? ROFLMAO...

Maybe we finally have a definition of the difference between a 'home' arranger and a 'professional' one.... 'Home' arrangers are not meant to be played on for any length of time.

It's not so much that 'it's like a customer saying these toyotas are garbage,the engines keep dying,yet he uses it for 4x4'n' it's more like 'it's like a customer saying these toyotas are garbage, the engines keep dying, yet he uses it for driving to the next state instead of just around the block'....

Even a 'home' user should expect to get YEARS of trouble-free operation for something he payed for that has no label that says 'Don't play this too much'!
