Pro Tools First can’t find the AAX plugins

Pro Tools First can’t find the AAX plugins

Unfortunately, you can’t use our AAX plugins with Pro Tools First.
Pro Tools First is a streamlined version of Pro Tools, available for free, which doesn’t support 3rd party plugins.

You’ll either need a commercial version of Pro Tools, or you need a VST or AU DAW like Ableton Live, Cubase, Logic Pro, Reaper, etc…
