MMRC USB connectivity

[Jesse Johannesen]

I just discovered the MMRC - I've been waiting for a MIDI router as comprehensive as this for years!

I've just pre-ordered mine.

I have a quick question about USB client connectivity.

I see that each of the 4 USB client connectors provides access to 4 MIDI streams.

My question is: is it possible to connect 4 separate hardware MIDI devices to each USB client connector via the 'virtual MIDI cable' functionality? This would provide 16 USB MIDI connections.

Could I connect a 4-port USB MIDI hub to a USB client connector and then separately address each of the 4 ports via the single USB connector, and thus connect to 4 hardware MIDI devices which have DIN MIDI connectors?

Thanks, Mick

Hey Mick, thanks for supporting the project!
I'm about 99% sure that I asked if this is possible when I first got my test unit, and if I remember correctly, the reason is that it is just a MIDI host and not a full fledged USB socket so to speak. It can't do all the things that a computer might if you plug in a device there. I will ask and verify that though and report back.
You may be able to use a MIDI device that has multiple MIDI virtual wires, however. This would be dependent on the device, and whether it "just works" or requires some drivers when plugged in, but as they say in the hot wheels commercials "some cars not for use with some sets". We are testing the device now and for the most part most MIDI class compliant devices do show up and work as expected, and if they have DIN MIDI, they work for sure via those ports.  Stay tuned for more info as we get a better picture of which devices have been successfully paired.
