I do have a CM11A (two, actually), but other than once for testing, I've never connected it to AHP.
I use a CM15A.
I don't know much about the support for the CM11A in AHP.
Seeing as you (supposedly) can't get AHP without paying for it, and you can't buy it without a CM15A or CM19A, I don't really know why they added the CM11A support in the first place.
Given the CM11A's small memory, I don't know if they ever intended for the user to download anything to it. Perhaps their application was for some sort of real-time control, perhaps using the web-enabled plugins? I don't really know.
