Here is a fun game: Have a few drinks on a Saturday night and try mapping your control surfaces!
Craig,
I found your SOS article and after following it verbatim I was able to gain control over the ProChannel.
It seems to behave differently when selecting ACT learn from the pulldown menu versus choosing it from the transport button. When I use the pulldown menu -> blue act button -> learn -> deslect act button, there is a pop up that asks for confirmation.
When I use the tansportbar button to bring up the ACT window, and follow the same procedure, there is never a confirmation dialog. I wonder if the absence of the confirmation dialog indicates there is a problem.
Also, the stuttering I was seeing had something to do with how the Axiom was transmitting controller values. I needed to use a different preset from the controller.
