Okay, compatibility mode didn't work for me, so I just reinstalled Reaper and all the drivers and now it's working. Glad I don't have to downgrade Windows! Anyway, thanks for the quick help.

Didn't know that was an option. I'll look into it and let you know.

I have a CTK 720 that I use as a midi controller with Reaper. Since upgrading my computer to Windows 10, Reaper no longer recognizes the keyboard. I tried re-installing the driver, but that didn't help. Anyone else having similar problems, or is there any word from Casio about upgrading the drivers for Windows 10?
