I think maybe I am miss using the term "mixer". I was looking for a program that could possibly arrange the music in sequential (I hope that word works) order.
Most store bought albums have songs arranged so that when listened to flow with one another. Instead of having the songs be like first half of CD all upbeat, last half all slow songs.
I don't know if I'm even making any sense! I had thought the mixing music was like I tried to explain and not editing. I have editing software and burning software.
