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).
