If you have previously connected a MIDI device to your computer, the KORG USB-MIDI Driver may not recognize it.
When a MIDI device is connected to the computer, it is registered as a MIDI device with the computer.
Devices used by the KORG USB-MIDI Driver need to be registered within the first 10 devices.
■ Use the KORG MIDI Driver Uninstall Utility included with KORG USB-MIDI Driver to check the registered MIDI devices.
(e.g.) When using microKEY2 with KORG USB-MIDI Driver.
1. Remove the microKEY2 from your computer.
2. From the Windows menu, select "Uninstall KORG USB-MIDI Device".
3. KORG MIDI Driver Uninstall Utility starts up.
Pressing the Next button displays the MIDI devices registered in the computer.
Confirm that the MIDI device you want to use is registered within the first 10 (midi0 ~ midi9).
*The displayed MIDI devices will vary depending on the PC environment.
*Windows creates a driver for each USB port of the PC, even for the same MIDI device. If you connect your MIDI device to multiple USB ports, that device name will be registered multiple times. Your MIDI device must be registered from midi0 to midi9 with the USB port you are using.
4-1. microKEY2 is registered within the first 10 (midi0 ~ midi9) and will work correctly.
4-2. microKEY2 is not registered within the first 10 (midi0 ~ midi9) and may not work correctly.
5.If there are more than 10 registered MIDI devices, delete unused devices among those registered within the first 10 (midi0 ~ midi9).
6. Connect microKEY2 to your computer.
7. Start the KORG MIDI Driver Uninstall Utility again, and confirm that microKEY2 is registered within the first 10 (midi0 ~ midi9).
8. Restart your computer.
