I bought a white KL 88 second hand and would like to know where to go to buy the music rest and PC tray that originally came with it and is missing from my unit?
I’m not sure exactly which version of the KL88 you have there, but i think the best course of action would be to log into your account to contact Arturia Support directly, to see if they might be able to point you in the right direction.
HTH!
