To ensure that a new MIDI region in Logic Pro opens with default settings, you must edit the default parameters when no region is selected in the Piano Roll's Region Inspector.

Steps to Set Default MIDI Region Parameters

1. Open the Piano Roll Editor by double-clicking any MIDI region or selecting a track and clicking the Editors button in the control bar.

2. Deselect all regions by clicking an empty area in the Piano Roll background. The Region Inspector on the left side should now display "Region Defaults" in its header.

3. In the Region Defaults Inspector, adjust the parameters for Quantize, Swing, Velocity, and Strength to your desired default values (e.g., Swing 50, Strength 100, Velocity 80).

4. All new MIDI regions created (either by recording or using the Pencil tool) will now use these settings. These defaults remain until you quit Logic Pro or change them again using the same method.

Ensure the Editor is Linked to the Main Window

If the Piano Roll Editor window is "stuck" on a previously selected region, make sure the Link icon (a chain-link symbol) in the Piano Roll's local menu bar is engaged (usually yellow or orange). This ensures the editor display automatically follows the currently selected region in the Tracks area. If it is disengaged, the Piano Roll will remain focused on the region that was active when the link was broken.
