Hi Florian,

Today I picked up my Mono Poly from the service center, they couldn't find the fault.

The first test i did was to check the Auto Damp switch operation, which seems to work properly.

Testing it deeply i noticed that holding down a key, and playing the rest of the voices, it works properly, no matter which voice is helded down, therefore it seems to exclude a bad functioning of the auto damp switch.

It's a strange defect, when it happens, the voices remains engaged but the corresponding leds switch off correctly..
