I think we have to be patient with d2d1 as it's slowly being developed. Most likely the focus is on d3d though, as most people want to run games not audio plugins
It might help if we create bug reports though, as like that they will see that there is interest in d2d1 and they will get bugs to fix and links to plugins to test with.
You can add
http://www.acustica-audio.com/index....179&Itemid=305 to the list, as afaik they work, and can draw some knobs, but not others.
