i have a X type of stand for my E60. i noticed when i play it standing (so the angle of stand is smaller) there is a shakeing type of movement that develops while playing the keys. when i play the keyboard with a larger angle (sitting) this movement does not occure.
my question is, does it harm the keyboard or not? is not a tremendious vibration, but is still a vibration, which i know is not recomended.
what do you think?
