using logic 9.1.8 - midi controller is korg prophecy -  i have my flashing amber in2  light on the the front of the unit doing its thing (if i hit keys on the key board i can see that the midi light respondes the same)- i go into the midi setup,  put it in test,  hit the triangle facing down on the rme icon and i see the midi out2 light flash on the unit. there is no response when i hit the in2 triangle .. however it keeps flashing steady.  - i was using presonus and everything was working fine.
