We wish to inform you that the current KORG USB-MIDI and KORG BLE-MIDI Drivers are not compatible with the recently released Windows 10 May 2019 Update and advise you not to update your operating system until compatible versions have been released by Korg. Of course we are working on the updated drivers now and will announce and release them as soon as they are ready.
We thank you in advance for your patience and understanding.
*If you have already performed an OS update, you may be able to use with the standard Windows driver (although we can’t guarantee the operation of our products).
July 5, 2019 postscript:
With regard to KORG BLE-MIDI Driver, we prepared the latest version (v1.12 r4) supporting Windows 10 May 2019 Update. And about KORG USB-MIDI Driver, we are working to support that Windows update, so please use the standard Windows driver or wait for a while.
