How can you change MIDI controls for the smart controls window?

The option that involves accessing the inspector in the Smart Controls window, clicking a parameter, and then using the Learn function for external assignment is correct because it directly relates to the way Logic Pro facilitates the mapping of MIDI controls to parameters within the Smart Controls. This process allows users to assign external MIDI controllers, such as keyboards or faders, to specific parameters in the Smart Controls. By selecting the desired parameter and activating the Learn function, Logic Pro can automatically recognize the MIDI input from the controller and assign it to the chosen parameter, thus enabling real-time control of that parameter during playback or recording.

This method is efficient and straightforward, allowing for quick customization of controls without the need for complex setups or third-party software. In contrast, the other options do not correctly describe the process for changing MIDI controls in the Smart Controls window.
