So far most all of the plugins, and SoundHack have been working under Lion. More testing needs to be done to make sure. The Spectral Shapers and Pvoc Kit copy protection is now working under Lion. With the exception of Pvoc Kit, Audio Units do not always display automation. All Audio Units will be updated in the next month to better respond to automation. RTAS plugins are yet untested, as ProTools is not yet supported under Lion.
