Could you suggest me a useful menu setting from the windows H9 controll software.
Well, you probably only want the wet signal and none of the dry signal. There's a setting called Kill Dry Audio that you can find under Pedal Settings / General Settings / Kill Dry Audio that does this.
Ok but, is there an insturment setting which will, on average give the most ‘neutral’ sound so you can use is with vocals or drums for instance and what about the level of the signals, how to adjust for line level.
