Double-check that you've installed the MPC drivers using the MPC 2 installer. This step is essential for proper integration with Logic Pro.

1. Open Finder.

2. Navigate to Macintosh HD (or your system drive) > Library > Audio > Plug-Ins > Components.

3. Locate the MPC Plugin component and move it to the Trash.
