To Larry...
Again there are many answers around this issue ( on the forum) this one is from John:
Do you have both the input and output of the pedal connected to you Basestation Pro? You have to connect both as the way the Basestation knows about the position of the pedal is by sending it a tone then seeing how loud the tone coming back is. To be clear:
*using a mono 1/4" jack to jack cable, connect the the Basestation socket labeled 'Volume Pedal 1, To Input' to the volume pedal input
*using a mono 1/4" jack to jack cable, connect the the Basestation socket labeled 'Volume Pedal 1, To Output' to the volume pedal output
If you get these the wrong way round, it won't work. After connecting it all, calibrate as normal.
Sorry if you've already done this, I just couldn't tell if you'd used one or two cables to hook the pedal up from your comments. It is possible to use one (stereo) cable to connect certain pedals such as the Yamaha FC3, but not the FV500.

Continuing...
About the "one cable" hook up with the YAMAHA FC3:
TRS jack cable, connect to the Base Station socket labeled "Volume Pedal 1 To Input"
After this you have to calibrate.
"KEYGROUP 1 MODE KEY" and with it pressed "PEDAL CALIBRATION" as in the quick reference guide KEY 4.
With the ALPHA in a vertical position, Pedal 1 uses the buttons in horizontal; from the edge - down (touch 1st key to min. value, then press the pedal all the way down touch the second key below to max. value. Just return to play mode.
(Pedal 2 uses the row to the left, again in horizontal.
Hope to hear you're piano sustain!
