I just found out that RB keeps running when i just select Midi-Out when i play a midifile to my Roland EXR-5 keyboard. This keyboard is connected to the UA-700 with both Midi-In and Midi-Out with ordinary Midi-cables. As soon as i also select Midi-In under [Midi Drv] in RealBand 2010.5 and i open the Midi setup dialog twice the access violation error occurs.

So everything seems to focus to the Midi-In. The Roland EXR-5 keyboard is Midi2, GS and XGLite compatible.
