How do you know what level you are at I use garageband on iOS and I usually have merged the vocals a few times when I get them sounding decent is normally like 4 versions panned left and right then merged I never merge the instruments then I save the track put it back double it go left right take wider stereo and widen it then make a mp4 so where am I going wrong and where do I find that number and my main problem is the kick and snare getting drowned out or the snare is way to loud in the mix I always have to chop every snare beat separate and lower it.
