I've become tired of manually plotting in-room sub response going the orthodox way using RS analog meter. It's a lengthy and cumbersome process to get the in-room response and then manually setting the filters on BFD. I think it's time to use REW, which will "HOPEFULLY" make my job easier. I want to hookup BFD with laptop to automatically set filters. REW help says I need to connect the pc soundcard from line out using midi interface on BFD. Can someone suggest any midi-to-line out cables??? I can't find any.
