As there are no other devices connected for this test, I am including only the relevent information:
Winx64 on CM 1.4

I have made an IMGUR album showing the issue:

Essentially, the MS-812 does not appear in the connect tab. It was there, and did not have any issues prior to connecting an AL-88c on the same network.

Please advise!

This is normal... the MS-812 is a target device, not a source device.

From the Connect tab, you can create a connection from source device output to target device input.

So there is no reason to see the MS-812 at the root level in the Connect tab, but you'll see it when you have selected a compatible connection source.

In your example, you can see from the overview that the MS-812 is connected to the MIDI device. So you'll see MS-812 if you go to the Connect tab, then expand the MIDI device until the MIDI channel pointing to the MS-812.

Of course, you're correct. I've never had better support for any product, and I sincerely appreciate your help!
