Smart Controls in GarageBand on Mac
Smart Controls let you quickly view and adjust the sound of the selected track. Each Smart Control features a set of screen controls. Adjusting a single screen control can modify one or more parameters for the track.
In the Smart Controls pane you can also add, reorder, and edit plug-ins, including Audio Units plug-ins installed on your computer.

Screen controls: Visual controls that let you control the sound of the track. Screen controls are labeled to make their functions easier to understand.
Smart Control inspector: You can access plug-ins including master effects, recording settings (for audio tracks), and a keyboard sensitivity control (for software instrument tracks).
Master button: Shows the Smart Controls for the master track.
EQ button: Opens the EQ effect for the selected track.
Tuner button: Opens the Tuner (audio tracks only).
Amp and Pedal buttons: Opens the Amp Designer and Pedalboard plug-ins (electric guitar patches only).
Arpeggiator button: Opens the Arpeggiator (software instrument tracks only).
