I'm having a problem getting an audio track to play the instruments from the library. I never have really tried to learn to use the audio tracks, I normally use EXS but today I wanted to learn to use the Audio tracks. So I pulled it up, selected Audio, Mono Input 1, put a check in the Record Enable Box, put a check in the open library box, but it won't play the instrument I choose. I can go to all my EXS tracks and my keyboard will play them, but for some reason it just won't play these blue audio tracks. Can someone please explain to me what I am doing wrong cuz I am very confused. Thanks!!
