Hi everybody,
i think I haven īt read this before here, if I missed it, sorry for the unnecessary information.
The thing to check after selfcalibration is the following:
View the Voices as they are played:
1. press Selet button to get to "Ext Funct"
2. press 7 then Enter
3. press + button to display "1"
4. Press Enter
5. the display shows the voice as it is played
Now hit the keys and when you here a fault or nothing - thats the voice with the fault.
Now change chips and see how it behaves, if the fault moves with the chip, its the chip.
Hope this helps,
Ralf
