This was a great help today December 2022!
Even with latest Korg driver, had to follow this video, add alias midi1 and midi3 for my MS-20 mini and microKEY37 keyboard, and KORGUM64.DRV in the midi1 and midi3 fields under Driver32 after installing the Korg driver today.
The microKEY32 was working before installing driver. Installed it to connect to MS-20mini. Computers are powerful, but so much trouble.
