I have closed logic, restarted Macbook. I have re-played the midi line and quantized it. No solution!!
I have now BIPed it to see the time shift. Then I bounced again with a EVB3 and the problem is gone ! It goes as far as that with other EXS presets it's also gone. Means my Yamaha Grand preset is "damaged"?
See the 2 bounced versions, the Yamaha is delayed:
