I was wondering if i needed a mixer or not to record music into tracktion 2....I have pc with windows xp pro....I'm going to get m-audio delta 44 soundcard on tuesday. I'm trying to track out some recorded songs made with motif into tracktion.I was told that i needed a mixer and i was told that i dont need one. If i do need a mixer, would a 4 channel dj mixer work for what i want to do?? Basically i'm trying to track out pre recorded songs in audio and record new songs in midi.
