Playing REW through JRiver MC

[burnhamjs]

I am trying to figure out how to use REW with JRiver MC such that I can see the effect of the the filters applied.  I see tboooe was able to get it working but I didn't want to ask it that old thread.  Does anybody know how I can route the REW output through JRMC such that I can measure my EQ'd speaker response at the listening position (Using a UMIK-1, USB mic)

 

And another question while I asking about REW.  I measure each speaker individually, but in the end I would like to measure all speakers together so I can see any interactive issues (phase, etc.)  Is there a way to play though all speakers in REW (5.1 system using ASIO4ALL drivers).

Thanks JCR.  That should work.
