Custom Function keys: Mackie Master Control

Google has failed me and I’m hoping someone could point me in the right direction.

I have the original Mackie Master Control (non pro) and everything is mapped correctly when Mackie Control is selected in the device setup.

I’m looking for a way to map one of the function keys to activate / enable a reverb plugin on the Master bus. With my Behringer Xtouch Compact I could map the enable switch using generic midi learn.

I don’t see an obvious way to achieve something similar using the Function Keys editor in the protocol settings. Is it even possible?

This is not possible if you run it over the mackie protocol. Though it would be cool to have some plugin-specific functionality mapped to it, either “learned” or via mapping files.

Right on.

I thought there might be some way to achieve this with the plugins shipped with Ardour but that answers that. Yes, that would be a neat feature.

Thank you.
