Keybed Repair
KRONOS Touch Screen
Hammer Felt

The 'E' above middle-C in this Korg Kronos music workstation made a sharp clacking sound when played hard.

We discovered that a layer of felt that the key hammer hits when thrown upward was damaged.

We removed the Kronos keyboard assembly, or keybed, and cut out the damaged felt (left).

Scuffed Key Frame

 

Because of the damaged felt, the key hammer could travel too high and strike the top of the key frame.

There was a dark line on the frame where the hammer was hitting (left).
