The WIDI Jack’s Bluetooth icon will appear in the MIDI studio window, indicating the successful connection. Please note, the MIDI studio can now be minimized to run in the background. If no music software is running, macOS will automatically disconnect the Bluetooth MIDI connection after a period to optimize resource usage. That is why it is recommended to keep MIDI studio running and minimize the view of the window.
