Rhodes Chroma Polaris

I've recently acquired the Amazing Chroma Polaris:)  It was equipped
with the original sustain & metronome pedal.  Though I do not have the
pedal used to access the Assignable Modulation Pedal Parameters.
I'm hoping someone might be able to recommend a replacement pedal that
can be used with these features?  Or more specifically if you have a
pedal you are using in this regard provide me with the model/brand.
Would any of the basic Moog EP-1/EP-2 expression pedals work?
Any help is greatly appreciated!  Thanks, -Charles
