I can't connect the Bluetooth devices even though it appears on the list on my iPhone/iPad.

    I just had this problem with my microKEY air after updating from Mojave to Monterey.
    Would not mount using the BLE-MIDI app; was already running the latest 1.04 firmware for the Korg. BLE-MIDI would see the microKEY, but the connect button did not connect it.

    Solution was to delete the existing microKEY entry in Mac Bluetooth preferences, then use BLE-MIDI to connect it. Success!
