I would like to be able to use Melodyne as a plugin with RB. I have to go to Reaper to be able to do this, but Reaper doesn't support a decent built in harmonizer. If you could add support for VST3's we could then access Melodyne as a plugin.

You could have a look at ReaVoice a built in plugin for Reaper.

There are more views of this harmoniser in Reaper just do a search on Reaper harmoniser.

Just a thought
