Emax

Hello all !!

I ve a Emax II HD and it works very good  - but 3 Days ago some Keys 
are working not or workin after three times pressing the same Key. When 
I play the emu from my Master Keyboad (MOUT Interface and a Kurzweil 
Piano ) it works without any Problems.So i thing its a hardwareproblem 
no daubt. But can anyone form tis group tell me what part is to change ?

thanks a lot and many greetings from Germany
