Bernie it’s been a while since I had bass pedals, but let me give a try.

1-Thee bass pedals and the Pa4x must talk to each other through the same midi channel.
2-Use one of the 16 channels that is not being used for the Acc. or control, or whatever else is being used.

On my Kn7000 I selected channel 5, if my memory is correct. When I used an external voice harmony the same thing applied; talking to on the same channel.

If you have 6 channels free; that are not being used, you can control 6 different external units. The bass pedals, a sound module, the coffee pot in your kitchen. Well I’m not sure about that last one. (smile)

I bought a book; Simplifying Midi, big help. If you go deeply into what midi can do (control) it can get very complicated. For what you are doing it not too involved.

The best part of Mr. Bernie A. is that he is always moving forward. Nice!
