When your first open your project, sort the tracks. If your tracks are in disorder, you’ll have trouble knowing which track you worked on, and you will waste time scrolling up and down looking for your Electric Guitar Solo track.
Usually I begin with drums, then bass, then acoustic and electric guitars, then piano and pads, then vocals and harmonies, from top to bottom.
Then, create subgroups and route your tracks correctly. Create a DRUMS bus, a GUITARS bus, a VOCALS bus, etc…
This will allow you to simplify your mix, control the volume of many tracks with just one fader, and apply EQ and Compression on all the tracks at once if you want to.
Listen to the song, and find the busiest part of the song. It can be the last chorus, or the bridge, etc…
Loop that part. This is the most complex part to mix, so if you start here and get it to sound great, the rest of the song will sound great.
