I just got a brand new Montage 8, FC7 & FC3A pedal. The FC7 pedal is hooked up to the Footcontroller 2 input. Most of the time the FC7 pedal flawlessly moves the Super Knob. Every once in a while it doesn't move it. I usually experience this when moving to a new Performance. Then I move the Super knob with my hand and after that the FC7 pedal works again. I also think that moving the pedal all the way to 0 (heel down) re-engages the super knob.
This would make me a bit nervous when playing live cause I wouldn't have any hands free. Has anybody had this problem? I updated the firmware to 2.0.
