MusicTechHelpGuy shows how Summing Stacks let you organize a mix without losing control over individual tracks. Group vocals, drums, keys, synths, bass, and effects, including their aux channels, into one folder that still lets you mute, solo, pan, and add plugins per track.
Each stack routes through its own bus, so the group's fader behaves like a single channel while every track inside stays editable. Building one stack per instrument category gives you a macro view of the mix instead of getting stuck adjusting tracks one at a time.
This setup makes broad moves fast: pull all the drums down a touch, push the keys up a bit, and hear how the whole balance shifts before diving back into detail work.
