From the developer:
Bluetooth MIDI Connect allows you to easily connect Korg's Bluetooth MIDI compatible controllers such as microKEY Air, nanoKEY Studio and nanoKONTROL Studio wirelessly with your Mac. You can open the Bluetooth MIDI connection panel from the System Menu and make a Bluetooth MIDI connection without needing to always open the Audio MIDI settings.
