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).

    on windows I had the blinking blue light problem:

    - I had to disconnect it from bluetooth devices
    - uninstall KORG BLE-MIDI Driver
    - then reinstalled KORG BLE-MIDI Driver https://www.korg.com/us/support/download/driver/0/530/2886/

    -Then connect it to bluetooth

    - Then open my DAW and i had to push some keys on the microKEY Air inside a plugin

    - Then it finally connected wireless. The good thing is that it stays that way


    If that does not work :

    - connect throuh usb, then restore to factory settings. Turn off then turn on while holding both octave buttons in for some seconds. 

    - disconnect from bluetooth

    - unistall all drivers

    - go into 'regedit* 

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

    -then delete all midi REG_SZ files with Korg in its's name

    -then reinstall first 'Korg usb-midi driver tools for windows' and  then Korg BLE-midi driver for window'

    - then put usb into keyboard then go to software meny under Korg and 'install Korg usb midi device'

    -Then connect it to bluetooth

    - Then open my DAW and i had to push some keys on the microKEY Air inside a plugin

    - Then it finally connected wireless. The good thing is that it stays that way

    The support sent me this message :
    1. Set Device to "10 or less" with "Uninstall KORG USB - MIDI Device".
    2. Manually erase "KORG BLE-MIDI Device" with Device Manager's Sound.
    (Please check with the attached image and delete it in the same way.)
    3. Uninstall "KORG BLE-MIDI Driver for Windows" with Program and Features.
    4. Reinstall KORG BLE-MIDI Driver for Windows. Then restart the PC.

    I think the harder step is to run the MIDI driver uninstaller (not the BLE one). The uninstaller provides a window where selecting all element cleans the BLE drivers also. Then reinstalling the BLE driver words fine :-)

    I got the nanokey studio recently and installed the Korg BLE-MIDI driver version 1.12 but i see that the pairing does not work . Though the nanokey STudio is detected in bluetooth scan and gets connnected . Same as what others mentioned above

    It does not appear as a midi device in any DAW either . When i go and check in Device Manager it still is using the Microsoft Driver .
    KORG please test whats going on and fix this . It would be great to have a working driver along with the steps to connect .
    This is supposed to be basic thing but why is this so complicated ?

    While it works perfectly on Mac's and iOS devices . I would suggest Korg to provide a UI which will help pair the BT-Midi devices and can be used to setup connections reliably.Similar to how Mac's provide a BLE-Midi Tool . This will really help.
    Somehow the driver does not get used by the device after pairing is done .
    Korg , please look at this and sort this out since we get such gadgets to use with Windows and not just iOS

    KORG are a bunch of shysters. I’ve got an iPad Pro and when I try to link using Bluetooth the iPad recognises the nanoKEY Studio, but the KORG app doesn’t. Likewise I have a Windows 10 PC (18 months old) and it’s the same problem. KORG should recognise that their app is shit and fix it instead of making these pathetic excuses.

    I just created a tutorial video on how to get this work:

    After applying Windows 10 update, my Korg devices stop working. Then I found this: https://thedigitallifestyle.com/w/index.php/2019/04/23/fixing-korg-usb-midi-driver-issues-in-windows-10-may-2019-update/
    Korg support is very bad. Great products but very bad support and Ableton Live support as well.

    Warning: First create a Registry Backup, then move forward. You may need to create an Alias for every damn midi device(not only Korg ones) in the same registry tree as your Korg devices. Korg devices may need to be between midi1 and midi9 to work. Hope it helps.

    der Vodi's video is what i had to resort to exactly, for the BLUETOOTH compatibility. BLE drivers just dont work at all. It's a real hassle to keep midiberry open and set that all up just for bluetooth

    Edit: oh! I did get it to work and show up in FL Studio when bluetooth connected!! The solution was to UNINSTALL the 'teVirtualMidi' driver from Device Manager. I had that installed because of previously using the MIDILoop third party software, and it looks like that conflicted with the BLE-MIDI drivers.

    The hint was how when I used the Korg Uninstaller, the BLE MIDI did not show up in that software but only this 'virtual midi'. Once i uninstalled teVirtualMidi, Uninstalled BLE Midi program from the Control Panel, and then reinstalled the BLE MIDI drivers, it now shows up and works perfectly. (as of today, october 2019, windows 10).
