- Navigate to the MIDI or Bluetooth MIDI settings within the application.
- Select the MD-BT01 (it may appear as "MidiPortA" or similar) from the list of available Bluetooth MIDI devices.
- Once connected, the indicator light on the MD-BT01 will typically change from flashing to solid, indicating a successful connection.
