Please note: Muro Box supports BLE MIDI starting from firmware version 1.2. Also note that your phone must have a special app installed to enable BLE MIDI.
Download and install the “Piano MIDI Bluetooth” app from Google Play.
Open the app, and tap the Bluetooth icon on the top toolbar.
Select “Start scan”. Make sure location services are enabled on your phone so that Bluetooth can discover the Muro Box. If the music box is found, the option “MUROBOX-MIDI” will appear. In the “Select MIDI mode” menu, choose “Controller” and press OK.
Play notes on the on-screen keyboard, and the music box will start playing.
