A friend of mine runs the repair dept of a very large music shop in UK. He has just had an XP50 in for repair. The display had gone.
He called Roland UK to order the new part only to be told that Roland do not support or carry spares for XP50 any more. Is this the same for all XP synths .. and if so has anyone got a 3rd party supplier in UK or USA who is now going to be doing spares for these keyboards. Come to think of it .... are there any 3rd party suppliers of spares for all of Rolands older equipment I have S760 which needs an OP1 board

Your friend should try Roland Benelux.
Somehow they usually manage to find things..
