Thanks again for your time. I have not been able to see if your advice works. I prepare helix after this season of live concerts, (Which for me starts next week). I bought helix only for a week, I have a 5-hour repertoire, it is impossible to plan everything in such a short time. Keep in mind that in my old boss pedalboard, live use 32 banks of 4 patches and all with 8/16 control assignments in real time expression pedal and control pedal. (I am very crazy ...) I also use on my electric guitar piezo bridge, then the helix I must find a way to play simultaneously acoustic and electric, (I think that with the microphonic input is possible create 2 signal streams to do this). I expected so much work, I am very fussy about sounds, reproduce entire albums live pink floyd, with one guitar It requires a lot of planning and concentration. But I am confident of this helix
