Roland, who make the venerable MIDI to USB interface the UM-1, and its more recent version the UM-1X, claim that they will not support Windows 10. And, indeed, when you install Windows 10 onto a machine with the UM-1X plugged in, it remains unrecognised by the new operating system.
You can fix this with a text editor. Remember also you must set your Windows installation NOT to enforce driver signing. Please see the comments (below) for how to do this.
- Download from Roland the driver archive for Windows 8.1. Its filename is um1_w81d_v101.zip.
- Unpack the archive.
- If you have a 64-bit machine, browse within the archive to this folder:
- Open the file RDIF1009.INF in your favourite text editor.
- Edit line 33, changing:
- Edit line 42, changing:
- Save this file and exit the editor.
One successful user reported that he plugged-in the UM-1 at this point.
- Browse to your Device Manager by holding down the ‘Windows’ key, pressing ‘R’, then selecting “Device Manager” from the menu that appears.
- Double-click on your non-functioning UM-1, which will be labelled “Unknown device”.
- Select the second tab: “Driver”
- Click the “Update driver…” button
- Click “Browse my computer for driver software”
- Browse to the folder containing the file you have just edited
- Click ‘OK’ to select the directory, then click ‘Next’
- When Windows complains “Windows can’t verify the publisher of this driver software”, click “Install this driver software anyway”
- Wait until you see “Windows has successfully updated your driver software.
Done! You’ve installed the Windows 8.1 driver for the Roland/Edirol UM-1X on Windows 10, even though Roland state they don’t support this device. I can confirm that the MIDI input works just fine.
