This error message appears when Resolume for some reason wasn't able to open a connection to your midi controller.

The most common cause for this is that your midi controller is already in use by another application. On Windows, a midi controller cannot be used by two applications at the same time.

Are you running any other applications that might be trying to access your midi devices?

I am quite sure there is nothing else running that would be using the controller. I can close Resolume and open ableton and it works fine. One would think if something was using it in the background it would not work in ableton either. I'll go through task manager again when I get to my studio today.

Thanks for clarifying. Since you didn't mention that in your original post, I had to ask :)

Could you please try renaming your config.xml file?

Did you solve the problem?
Actually I have the same (I think it came up with the installation of Res6 Beta).
I use the APC Mini
