Very nice use of those plugins, I even have trouble (aside from the oscx3) having those in my songs, Fl Slayer being the hardest on for me. I can say there are great piano VST/plugins out there better that fl keys like Nexus (might cost you). You can make an amazing piano through Sytrus and plenty of effects if strapped for money and still have an awesome Piano! This is really good melody, keep it up!
