I just went to an audio pro store, and yay not only did they have MIDI cables (Roland branded ones too), but they also had a UM-ONE mk2. Plugged it in, attached it to the Yamaha, and chained the through to the Roland, and now I’m driving both synth’s from Windows 10.

I also picked up a Roland ED UM-4 Super MPU64 … which sounded awesome as it has four MIDI out’s but apparently this thing has zero driver support… And Roland pulled ALL the drivers for this thing, so … It’s a lump of metal right now.

I just tried Windows 2000, and there was no automatic drivers. I can’t find actual Windows drivers for this thing, so I have a feeling the automatic drivers on Windows 10 x64 may actually not work… Or at least on my machine. I should try one of those IE VM’s with Windows 10…

Yes, on Windows 10 it will download them from Windows Update but these are Roland’s drivers.

Does it use it’s own drivers? I’m starting to think, that since Windows XP detects this on it’s own (haven’t tried Windows 2000 yet), that the fault may be actually in the Microsoft drivers….
