Its nice to see the drum replacer and its very nice to see more ARA development.
But unless I missed something in the documentation, or perhaps there is something in Platinum that is not in X3, there is no equivalent to the VST/Direct X Plug In Manager for ARA effects. So every time you click to edit in Region Effects you have to choose from any installed ARA effect.
For instance I got so tired of seeing Melodyne, which I rarely use, I went and un-installed it in Windows. It would have been nice to have it available but hidden.
Since I almost never record acoustic drums it would be nice to have the effect available, but hidden until needed.
BTW, my spelling corrector tells me Replacer is not a valid word.
