When buying keyboard...
You'd sure check the functions,sounds demos etc.We' d even check whether the keys are ok & on same level- otherwise it would easily catch the eye right?There lies the problem.In my case the keyboard looked perfect when I saw it in the showroom. It was only after I got home & had a look at it from a distance I noticed the undulation of the keys - some were up or down - just not perfectly on same level.
It wouldn't cause any hinder when playing the keyboard, but I could do without it.
So if you are buying a keyboard, step back a few feet & see if the keys are all on the same level.
