From the View menu, choose Show Bus Tracks to toggle the display of bus tracks at the bottom of the track view. A bus track exists for each bus, input bus, assignable effects chain, and soft synth in your project.
You can use bus tracks to automate volume, panning, and effect parameters using envelopes. If a bus track has envelopes applied, its icon will include a fader
