Thanks Tone,

dont know haw to test Midi ather way.Fact is Audya show Midi error and I cant recive midi mesages to my Comp via rear USB port.Strange is cos Audya dont show any problems about USB ports but midi mesages cant go thru.
When I conect Audya to Comp then Comp can recognize instrument-that mean Audya conect to PC corectly.
On net I found a wery good free program to monitoring all midi mesages who com from diferent Midi kayboards to PC.Hes name is MIDI OX.That program when is in run position and you haw conect any midi kayboard to PC incessantly monitoring all midi traffic betwen instrument and PC.
That program dont show any midi treffic in my case.I recomendet that free program to all who want to see all Midi mesages betwen instrument and PC.

Thanks for any help in advance....
