I never used rewire before and don't have a clue yet on how to use it. I have waves plugins and I guess Waves Rewire was installed. I just uninstalled X2  32bit and installed X2a 64bit. I noticed the 32bit version had Waves rewire that I could select from the browser synth section but it's greyed out now. How do I get it back and where is a good place to learn using rewire? I also Have Studio One 2 64bit installed. Am I correct that rewire is to communicate between apps?
 
Thanks.
