I believe we're getting off-topic, but I think but I'm not sure that Roland pedals are the opposite polarity of Yamaha pedals, so unless your expression pedal has a polarity switch, you might have problems using it on your Yamaha.

That pedal steel feature sounds wonderful. Please explain. Do you have to split the keyboard to use this feature? I always hoped for a pedal steel feature that only bends into the harmony of the left hand chord. I wonder if this is possible. I think the X1 might have a feature like this.
