Worpress pluging combination

Im using the pie registration plugin and i want to know how can i automatecly define a role (in my case i want to define as suscriber) when people register and login. I want to do this because i want to restrict some zones of the website and redirect those zones for the register or login page. Since the free version of the plugin doesnt have restricted areas im also using the plugin called members that does 50% of what i want. So i want to combine these 2 plugins functionalities.

tldr: how can i give a the role subscriber on pie-registration?
