Voloco is a free VST plugin that comes with just 6 presets but you will be able to control the key, scale, and pitch correction. Apparently, this is made especially for creative use and if you are looking for some creative effects on your vocals then you should get this plugin.
The pro version of this plugin is still under development and this is the reason they have a free version out to try out with limited features.
