DDMF has announced that its plugin chainer/wrapper Metaplugin has now also been released in RTAS format.
You can therefore use Metaplugin as a VST-RTAS wrapper or a VST-AU wrapper if you just want to load single non-RTAS plugins into ProTools, or, of course, you can go completely wild and create the effect or instrument chain of your dreams.
Go give the demo a spin, or if you already own Metaplugin for a different platform, the RTAS version is free for you.
Price: $49.
