Gilbert..that was my point..a Yamaha Tyros4 owner posted on a Yamaha club..and the reaction was predictable with a negative comment...

I didn't see any discussion about the possible problem..just retaliation against the poster...who seems to be respected by many Yamaha folks..

It sorta kills any effort to find out if there was a problem..or not..

Turning a head..or a cold shoulder doesn't resolve anything..
