Aaah, yeah of course. I opened it one time try to fix it myself. I've send it to Roland Belgium one time to fix,...got it back pretty damaged,...they didn't packet it propper, so both plastic sides (left/right) were cracked during transport and had no spare parts for that. Didn't had to pay the keys repair, but after 6 months or so, keys start dropping out again or lost their velocity, what a bummer!
