Or do i literally just need like a midi or something hardware wise to plug in and Rapture is only there to manipulate the sound of what device is connected
Actually it's the opposite. A MIDI Interface (keyboard or controller) is designed to utilize
the VSTi. The notes on the Keyboard send a MIDI message sent to the VSTi to activate
whatever sound is mapped to that note. So, if you have a Piano VSTi, and play Middle C
on the Keyboard, you will be playing Middle C on the Piano VSTi.
Some VSTi's have "virtual Keyboards" on the interface. If you press a note on that keyboard
you get the associated sound, so that you don't need a MIDI controller.
