Just purchased the PX/5S and am using it strictly as a MIDI keyboard with Cubase 8 Pro. Everything is working as it should except I noticed that, with every track I record, the Casio is sending data I'venever seen before. That is, MIDI CC, controller #88 ? I looked up the tables fir this but it is "unspecified" and seems to be with every Note-on, Note Off. Anyone know how to turn this off ?
