Hi,
Thanks for letting us know. You might want to talk to Korg about their compatibility. Perhaps they broke USB compliance with their firmware update. Perhaps there is a “compatibility” mode in the new firmware. Check their release notes or updated manual.
Some vendors do this where they have a “class compliant” driver and an “extended feature” driver that only works with their supplied USB drivers which of course they only provide on Windows or Mac.
For instance, I have a Roland device that has an enhanced mode which only works with their driver on Windows so don’t install the special driver and in the firmware mode, I leave it on the normal “compatibility mode”
I’ll check with Florian also to see if he can reach out to Korg for help to see what they did.
@FlorianBomers FYI.
