The XP80's manual on p.67 says:
"Tx Switch: At OFF, the part responds to the keyboard, but keyboard performance data (midi messages) will not be sent from MIDI OUT." But when I switch it off, the part responds to the keyboard AND IS sent to midi out!
"Local Switch: At OFF, the keyboard will not play that part, but keyboard performance data (midi messages) will be sent from MIDI OUT." But again, the part RESPONDS to the keyboard, and IS sent to midi out!
Please help me, I just don't know what to do, nothing works...
