I'm not sure. I am still on an old version. 7.2.3
I know that when I right click on the Logic icon in applications I can select
open package contents.. then find the different control surfaces in there.
not sure what format they are in or if you need a development kit.
I noticed that someone made one for the old IBK 10 control, but nothing
seemed to be assigned. so maybe it was a plan that never came to fruition.
how he got an unassigned control surface plug-in with the Logic distribution though
I have no idea.
not sure if there are any clues in this page. http://www.delora.com/tips_and_trend..._problems.html
