This Virus has been bought new years ago with O.S. 4.07
during it's life it's been updated to 4.50 without any problems, after that the smaller
updates were skipped till 4.90, after upgrading to that, then the problem showed up right away, i went back to the previous 4.50 but the problem didn't solve, so since that day it can only be used as a module, if i use it's own keys the results are very unpredictable, you often have to puss few times on a key for it to sound and notes hang lot's of times, if you push 10 times, notes hang 7 times, that much, so it's not useable.
I think it has a defective keyboard controller and i have to send it to Germany for repairs, but before i do maybe someone here knows another solution ?
Hard reset and loading whatever OS into the machine doesn't change anything, as a module it works perfect, but when using it's own keys it sucks.
Thanks in Advance
