KORG app Help Center

I installed the KORG BLE-MIDI Driver but I cannot use the Bluetooth device.

Please check the following.
- Check if your PC meets the required specs. (Windows 8.1 or later, Bluetooth 4.0)
- Make sure you have the latest KORG BLE-MIDI Driver installed.
- Try removing the paired Bluetooth device and pair it again.
- Windows has an "Auto connect/disconnect feature for Bluetooth". When connecting Bluetooth, you must launch the MIDI application.
- If you are using USB Bluetooth Adaptor, it may not work if you install the attached driver to the USB Bluetooth Adaptor. Please uninstall the attached driver and check the connection.
- If you are using multiple MIDI devices, sometimes the Bluetooth MIDI Device will not work. In such cases, follow the steps below to delete information on unused MIDI Devices and reinstall the KORG BLE-MIDI Driver.

  1. Download and install the KORG USB-MIDI Driver from the KORG Website. 
  2. Launch "Uninstall KORG USB-MIDI Device".
  3. You will see a list of MIDI Devices. Delete devices that are not being used.

    My PC meets the required specs :
    - Dell Precision 3520
    - Windows 10 pro 64 bit version 1709
    - Intel® Dual Band Wireless-AC 8265 driver version, Bluetooth version 4.2 (up to date)
    - just installed Korg BLE driver for windows version

    What happens :
    - I switch the blueetooth on the microkey2-37 air keyboard
    - the light led becomes blue and blinking
    - I search, find, and add it using windows bluetooth manager
    - the light led remains blue and stops blinking
    - I appears in connected devices as "microKEY2-37 Air and connected"
    - with not action, the light led restarts blinking
    - When I start my music software, midi ports are not detected.

    I looked further :
    When I switch the keyboard off, it still appears as "connected"
    When I try to launch programs in C:\Program Files (x86)\KORG\KORG BLE-MIDI Driver like EzSetup.exe, the message "ERROR : No device is plugged in."
    When I look in the configuration pannel, a new PC appears with the name "microKEY2-37 Air" only using microsoft driver files.

    Maybe the installation fails because Windows drivers are preferred to the Korg ones, and that microsoft drivers do not manage MIDI... How can I force the use of Korg drivers ?

    How can I investigate ? Could you please give me some diagnostic steps and support ?

    I'm having the exact same problem. Any solutions so far?

    I've done all the suggested actions with no success. I found that everything is working ok but the Korg BLE driver.The pairing works fine. After pairing, the MIDI-Controller (e.g. nanoKEY) can be seen in any App that supports the new Windows UWP MIDI API (e.g. MIDIberry from http://newbodyfresher.linclip.com/). Unfortunately most major MIDI Apps do not (yet) support the new UWP API and therefore they cannot "see" the nanoKey device.In the past, the Korg BLE driver was bridge between the new UWP API and the old MME API (by providing the virtual "Korg BLE MIDI Device"). The virtual device can still be seen in the Device Manager, but it stopped functioning (maybe due to another major Windows 10 update to Ver. 1709). You cannot see the BLE MIDI device as source in any MIDI application.The workaround is to use a combination of MIDIberry and a loopback software (like https://www.tobias-erichsen.de/software/loopmidi.html). But this is not convenient. I'm expecting Korg to fix the BLE driver.By the way: The connection LED keeps flashing even after pairing. This is normal. It will stop flashing as soon as any software is accessing the API (e.g. MIDIberry). As soon as you close the software the LED will start flashing again. So the LED doesn't indicate the pairing state, but the actual usage state (which is not clearly documented in the manual).
