GarageBand for Mac: Smart Controls overview
Smart Controls let you control the sound of the selected track using a set of onscreen controls. Smart Controls can control both software instruments (on software instrument tracks) and effects (on audio, software instrument, and Drummer tracks).
Each Smart Control has a set of screen controls. Adjusting a single screen control can change one or more aspects of the sound. Screen controls are labeled to help you understand which aspect of the sound each one affects.
Smart Controls typically include EQ or tone controls, reverb and other effect controls, and controls specific to the type of track or instrument. For example, the Smart Control for a synthesizer might include screen controls for choosing the waveform and adjusting the resonance and filter cutoff, while one for a string instrument might include controls for changing the articulation.
When you record a software instrument, any movements of screen controls are also recorded and can be edited in the Piano Roll Editor. For more information, see Use automation in the Piano Roll Editor.
In the Smart Controls pane you can also add, reorder, and edit plug-ins, including Audio Units plug-ins installed on your computer.
On a Mac equipped with a Touch Bar, you can use the Touch Bar to adjust screen controls on the selected track.

For audio tracks, you can edit recording settings, open the Tuner, and open the Amp Designer, Bass Amp Designer, and Pedalboard plug-ins. For software instrument tracks, you can set keyboard sensitivity and use the Arpeggiator.
