Thanx so much for testing, PriviaMan!
Yes, this MUST be sorted out soonest possible! The addition of a (well functioning) expression pedal is the main reason for me to choose PX-560 as a weighted midi companion to my Nord Stage SW73 and MainStage rig. This thread was started in September, and I can't see this problem's been addressed by Casio officials yet? Correct me if I'm wrong.
I have no other choice to wait with my purchase, or look to other options. Sad.
(For me it's no solution to use CC#7 Volume messages for the pedal - in MainStage I assign CC#7 to a midi knob controlling the max volume, and the exp. pedal always fading in and out to this max value. MainStage also giving the possibility of ignoring exp.pedal messages, but still controlling volume with the CC#7 knob - i.e. one layer fading in, the other being constant on)
Has anybody contacted Casio support about this?
