Connect two MRCCs and a Remote 7

[oldgearguy]

With 2 MRCCs working in tandem, will both need to be connected via USB to the computer for a) firmware updates, and / or b) routing to a DAW?


Thanks!

You will need to connect each MRCC to the computer, one at a time, to do FW updates. 
They can both be connected by USB to your computer if you need both showing up in your DAW. That would be the most efficient way to route to specific outputs from the DAW, rather than routing from the DAW to the first MRCC, then routing to the other MRCC. That's more complication and adds an extra hop that will add latency. 

So if you connect both MRCCs to the computer you will be able to see 24 distinct virtual ports?  That's great if it "just works" without having to do anything extra.
