The first night I did this, it worked great. Now, when I record, I am also getting an unprocessed guitar along with the processed guitar tone going through the various blocks in the chain. No idea what happened or changed. On ONLY want the stereo signal from rows 2 and 4 in the grid. I do NOT want an additional unprocessed clean signal being passed through to QT on the Mac. Please advise on what settings in the FX III need to be adjusted. I have turned all unused rows, those that are not 2 and 4, volume all the way down in the output mixer. Doesn't help. So this unprocessed guitar signal is coming from somewhere OTHER than the grid. Thank you!~
