I kinda did that with my first track, except I bussed different tracks together and grouped drums, synths, sweeps, and other shit then adjusted them in the mixer, except I just put a limiter and gain plugin on the output channel so it peaked around -3db. I only read up a bit on the process before I mixed down so it didnt come out sounding amazing or anything plus I think it was too quiet. what Im asking though, is when this next track is ready to be mastered, would I send the bounced audio track with all tracks together, or seperate ones e.g. drums, synths, bass/sub-bass, white noise sweeps?
