Help with Rotary on RD 2000

[ThatKeysPlayer]

Hi all

How do I apply a global rotary effect onto the RD 2000.

For context, I am using around 3 organ sounds at the same time and I am using a pedal in the FC1 slot to control the rotary effect however it only seems to apply the effect to the sound that is currently selected at the top of the piano. How would I make it apply to ALL of the channels simultaneously like a pitch bend would.

Any help would be appreciated.

Many thanks

I have this question too, but due to a lack of responses here I gather the answer is it can't be done?
