Roland AT-900c larger pedal board.

I don't know if anybody else in the U.K. has noticed but most used AT-900c organs are for sale with the small PK-7 pedal board and large bench stool, presumably as Roland stopped producing the PK-25 at the same time as the organs there were not enough to go round! Obviously the larger pedal board is as rare as hen's teeth as it is used in other combinations.

Has anybody tried any other manufacturer's 25 note board with the Roland?

Perhaps someone else can give a specific answer about AT900C.
Howerver I've heard about people using Hammond pedals with Roland VR09/VR730. VR09 has the same midi channels Upper 4, Lower 3 and Pedal 2. Channel 1 i specifyed as the dual or layered vocie but in Atelier as Solo.
It seems to be no damper pedal input in the AT900C. There is a damper pedal in the Roland pedal boards so they seems to be only have been thinking of using it with their pedal board.
Strange that the manual does not describe how to connect another pedal board thans roland that is connected via the pk connectero (I would guees it's ordinary midi with additional power supply to the pedal board).
Unfortunalely I don't think there are any 25 pedal boards with such great features as Roland boards but some or all feature could perhaps done in other way with midi.
