Mix bus routing in Pro Tools involves creating a central Aux Input channel that acts as a 'summing' point where all individual tracks flow before reaching your final hardware outputs.

What to do
  1. 1.Create a new Stereo Aux Input (Shift + Cmd + N) and label it 'MIX BUS'.
  2. 2.Set the input of this Aux track to a new internal Bus (e.g., Bus 1-2) and rename that bus 'Mix Bus'.
  3. 3.Select all your individual instrument and vocal tracks, then change their output routing from 'Out 1-2' to the 'Mix Bus'.
  4. 4.Set the output of your 'MIX BUS' Aux track to your primary physical monitor outputs (usually Out 1-2).
Common mistakes
  • ×Ensure your Mix Bus fader is set to 0.0 (Unity) initially to avoid unintended gain staging issues.
  • ×Check that no tracks are accidentally bypassing the bus and going straight to the hardware outputs, which can cause phase or balance issues.
  • ×Avoid 'Solo' isolated tracks unless you have 'Solo Safe' enabled on the Aux Bus (Cmd + Click the Solo button) otherwise you won't hear anything when soloing individual tracks.
Pro tip

Use the 'Option' (Mac) or 'Alt' (Win) modifier while selecting an output to change the routing for all selected tracks simultaneously, saving you from routing dozens of tracks one by one.
