Jim,
I know it will work smile
It is not overkill, since it is the most basic one I found to connect two computers by USB>USB for MIDI work bypassing interface.
I have seen larger USB MIDI routers, they are the complex ones smile But I have not seen anything close to simplicity, features, size and price to the one I posted. My concerns are: it's a one man company, device is ~9 years old and it is not available in US (I guess they will ship)

If you have a better USB to USB MIDI solution, please share, as this is the only one I was able to find.... and the reason for this post.
