I set up an RME FF UC with Au Lab and soundflower for an active speaker system. I use Au Lab for crossover, eq and delay. Works great! Now I tried to set up REW on a Mac, OS 10.6, trying to route the signal through Au Lab. Through the loopback function of the REW I tried to route the output of the RME back into REW along with the Mic signal. However, no luck. Do you have some comments on how to configure REW with soundflower and Au Lab? Thanks in advance!
