Pairing with the DUAL CUBE BASS LX Editor must be performed from within the app's Bluetooth settings screen. Tapping "DUAL CUBE MIDI" on the mobile device's Bluetooth settings screen will not establish a connection to the app.
If "DUAL CUBE MIDI" has already been connected from the mobile device's Bluetooth settings screen, unpair (delete) "DUAL CUBE MIDI," and then complete pairing from the Bluetooth settings screen within the app.
For connection details, refer to "Connecting the DUAL CUBE BASS LX Editor iOS App to the DUAL CUBE BASS LX" or "Connecting the DUAL CUBE BASS LX Editor Android App to the DUAL CUBE BASS LX".
