Hi Keith

Perhaps check what driver your UM1X is using and if it shows a compatibility warning.

I am using a Roland UM One with windows 10 with no issues.

I went to Device Manager and checked and found these driver settings. Just type 'Device Manager' on the Windows Search bar at the bottom LH corner of your screen, then navigate to and expand Sound video and game controllers.

Do advise if any item has an adjacent yellow or red exclamation mark. Do advise what driver is being used, similar to what I've shown below.
