Hi, I am not sure if I have set up the midi.audio drivers set correctly and would greatly appreciate some help. I am using 2009 Ultra Pack with all the bells and whistles and am a novice that understands more from explaning how other than reading how. I can hear midi fine but its the real tracks I have the problem with. Some real tracks are worbbled..I made an arrangement of a country song..picked a style I likes all real tracks..I have tempo set at suggested range..arrangement sounds fine but something is not right..I solo each track..all tracks sound good except rythmn guitar that is worbled. I adjust tempo up and down to see if it will correct and it stays the same. Any ideas? Thanks, Jerry
