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.

    This is ridiculous.
    Okay so don't buy more than 10 Korg synths guys, is that the idea? Because that's the limit of the Korg USB driver, don't buy more than 10 Korg keyboards? What????!!!!!!
    Please Korg, use some of that money I spent on my Prologue 16 and hire some real software developers, because you guys are stuck in the 1900's !

    Here is the reply from Korg, it seems they are confused about the ability of Windows 10 to host more than 100 USB MIDI device ports. They think Windows 10 has the same 10 device limit that Windows 7 had.
    Hey Korg! Windows 10 is not Windows 7 !! Hello !!?

    Maybe it's time to give up and go buy your gear from Arturia or Novation or Akai? Arturia has really good software support.

    Hello,

    Thank you for contacting us.

    The reason why you cannot use more than 10 MIDI devices is due to the specification of the Windows Driver.
    Even if you use the same device, every time you change the USB port, the Driver will be installed and counted towards the 10 device limit.
    This is why the device itself is not recognized even if it is powered from the USB port. This is not caused by the Korg USB-MIDI Driver.

    Please refer to the following FAQ and if you have more than 10 devices registered, please limit the number to 10. Also, please use the same USB port as much as possible.

    Best regards,

    My solution:

    Delete the registration keys that you think are not useful via the "Uninstall Korg USB-Midi Devices" software. I did it for my Radias which then jumped to the 6th position in the Registry Editor.
    Change the Korg midi set up to 32 bit (For me even if my PC is Windows 64) via the "Korg USB-Midi Driver" software.
    Change the Midi Preferences in the Radias Sound Editor as follow:
    Midi IN /Radias Kbd/Knb
    Midi OUT/RADIAS Sound
    Note Midi IN/Radias Midi IN.
     
    Works perfect for me now.

    I'm keen to use the new Wavestate software that has just been released. However the Korg connection software still won't work with Windows 10 21H1 so my PC doesn't recognise the Wavestate via USB. The Australian distributor sent me a list of software that is considered incompatible and Windows 10 21H1 is listed but they have no ETA for a fix.

    Is it possible to start agitating collectively since this issue has been around for a year or more.
