hi, i have installed 'Aureal vortex AU8830' soundcard. When i connect it to my keyboard (Korg X5D) i cant hear or record any midi input sound from my keyboard, although the output sound of my earler recorded files is properly played. Earlier i was using Nvidia Nforce sound card in that card both Midi in & out sounds were heard & functioning properly. plz tell how to make my vortex au8830 work both ways ?????????
