Diki, I e-mailed you but I quess your mail washer ate it.
I have connected my Electro to my G70, and have, in this case, assigned it to UP1 and LW1 in a split. My problem is playing a style(requiring local on), and not layering a G70 sound with it. Since the volume slider controls both instruments, I can't lower or mute the G70 voice, leaving the Nord, and local off turns off all G70 sounds, including arranger.
