Thank you, Peter.
I have a better understanding of the issue now.
My first Airturn Pedal, BT500s-4, is assigned actions the way you recommend, and it works well. I bought the second Airturn pedal, a BT500s-6, later and tried assigning actions in the same way, but it would not execute any actions. (The field would populate with a port number from the new pedal, but that is all).
So looking around, I found the Settings > Airturn Setup, and tried to use that for the second Airturn pedal. Success! It worked! So I have had two working Airturn pedals this way. The only problem is I cannot scroll down the Airturn assignment menu, (pictured above), far enough to reach the actions I need.
I do not mind this work around because it's really great to have 2 Airturns working together. Is there any way that you can make the menu, (pictured above), scrollable?
Thank you for your time. G-
