sound only coming out on midi channel 2

  • Today I went to open my virus ti desktop and no sound was coming out but I saw the movement in the mix tab..i messed around and found that sound will come on but ONLY if i go into the inspector and put " MIDI Channel" on 2..i use a m audio oxygen 49 as my midi controller ...also some of the bank sounds are very slow when they do play...I'm on Logic 8 ..how can I get it back to I can play using " ALL MIDI "
