Troubleshooting

"fatal error too many threads" issue with KORG controllers

Some users reported that they had a problem in using MidiJack with KORG MIDI controllers (nanoKONTROL, nanoKey, etc.). Although I haven't identified the root cause of the problem, it seems there is an integration issue between the KORG MIDI driver and MidiJack.

Fortunately, you can avoid the problem by switching to the built-in class driver. These KORG controllers are usually class-compliant, and thus you can use the class driver safely.

Steps for switching to the class driver

1. (optional) Uninstall the KORG MIDI driver.
2. Open Device Manager.
3. Select the target device and open Properties.
   
4. Select "Update Driver...".
   
5. Select "Browse my computer for driver software".
   
6. Select "Let me pick from a list of device drivers on my computer".
   
7. Select "USB Audio Device" from the hardware list.
   
8. That's it!
