Beaky,

We can all speculate on the cause of the S900's issues...the dropped palette one is viable, as is a batch that slipped through quality control...I'm inclined to go with the former as the keyboards in question were all in the same destination area.

A large heavy palette dropped from even a short distance could/would wreak havoc on connectors to wheels, data dials, USB ports, screens, even speakers.

A slip in quality control on the assembly line would cause identical problems with the units...as it stands, the issues were varied.

Whatever the cause, Yamaha is doing it's usual thorough investigation and will correct any current problems.

They did help you, didn't they?

Glad you getting along fine with both S900s.

All the best,

Ian
