we are trying to get our system set up for this concert but we are having some difficulties. there are four instruments. they all have automation that determines how much of the signal is sent to a reverb (bus). the reverb bus gets sent out of outputs 1 and 2 tracks 1-4 get sent out of output 3, 4, 5, 6 all input tracks are input monitoring and record enabled. what we want is to send FOH the four dry tracks and the reverb with automation but when we hit play the tracks stop sending to the bus for some reason. any ideas? thank you
