John, thanks for taking the time to respond. I do all my programming at home, and like yourself (probably), spend hours balancing sounds and getting the volumes right. However, sometimes on a gig, different acoustics cause programmed sounds to change due to room response. Usually for me, it's bass and drums. So if there's a way to adjust bass and drums just for the night in that venue, then it would be great. BTW - I do use a crossover. It is built into my sub and is set at 100hz. When you say the sequencer caused the sub sound to change, what do you mean? Were you using a 16 part sequence, or a sequence based on a composer pattern? I can get the SD card to remember sub out setting for composer patterns no trouble at all, but there doesn't seem to be any provision in the settings to apply to individual parts (such as part 2 for bass or part 10 for drums) Unless you have found a way. Be pleased to hear back again from you with the answer.
