KORG app Help Center

Windows is unable to recognize a USB-MIDI device.

If you have already connected 10 MIDI devices to your PC, a new device may not be recognized.

Because Windows assigns the driver for MIDI devices by USB port, it is possible to exceed 10 registered MIDI devices even if you have not connected that many unique devices. 

Please use the KORG MIDI Driver Uninstall Utility included in the KORG USB - MIDI Driver and remove MIDI devices until there are less than 10.

    I have a VOX Valvetronix AMP that has a USB connection uses a KORG USB midi driver.
    The connection has to be made within the old 10-MIDI-port-limitation, otherwise the AMP is not seen by the KORG Tone Room software.

    Now strange things (?) happen on my Windows 10 system.

    The driver always gets installed to the 11th port (mid10 or higher), though the ports mid1-mid9 are still available and not taken by any other device.

    How can that happen?
    How can I handle the situation, f.e. manually switch the AMP to use mid1-mid9 for the connection?

    Thx in advance for every hint.

    Best, Adrian

    Have to change regedit two places, and remember to restart pc after the changes. Then check in Uninstall Korg USB-midi Device software if it's between midi1 to midi10. If not use midi2 or midi3 and so on in regedit.

    This solution works for everybody especially them who have updated to the latest Windows 1903 build

    I have installed the latest driver released from Korg (2020) and still, when I run Korg editor the software shows a warning saying that there is no MIDI ports available, both in and out. I dont have any other midi device. So I dont understand why it still keeps saying that there is no MIDI ports availabe in Windows 10.
