Hi, I worked on a new plugin interface, it is not yet finished and set in stone, but ready enough to gather initial feedback and advice. The specification is hosted on github: https://github.com/free-audio/clap and is available under the MIT license. There is a generated specification document at: http://free-audio.github.io/clap/ I hope that you'll find it interesting and give it a chance. Thanks. Regards, -- Alexandre Bique
