I wonder if he installed the original drivers and they are controlling the keyboard? Maybe he should uninstall the drivers and let Win 10 find the keyboard via new hardware? He may have to unplug the keyboard, boot Win 10, then plug in the keyboard. IIRC I had to do this a few years back when my Roland Octa-Capture audio interface when from Roland drivers to Won 10 drivers. It might be worth a try. YMMV


I think my wife has started to show the first signs of dementia.
She said she can't remember what she ever saw in me!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
