Hi. I am new to the Line6 Helix and in the past have had not much experience with multieffects boards. When adjusting the volume via EXP2 pedal, when thereafter stepping off the pedal after attaining the desired volume, the volume reduces somewhat in the next milli seconds to a lower volume. Is this a settings problem or does this indicate a problem withe the hardware? It is rather frustration though. Can someone help me here? Thanks
