A band I am in decided to use MP3 sound files from Karaoke Version to replace a bass player and drummer who had left the band. The backing tracks were played from laptop to mixer to PA system via several different audio interfaces that we tried . Not until I purchased Swamp Industries Sterio AV DI Box for PC/Laptop/iPad etc did we get the audio results we were searching for.
