Using HD500x with DT25. Is there any way to specify looper playback volume per patch? If I record a loop with a rhythm patch that uses one of the 4 modes of the DT, then switch to play over the loop with an overdrive that uses a different amp mode the volume of the loop playback jumps. If I could set the looper volume per preset, I could balance the playback volume across patches. Is this possible or is there some other clever solution?
