I love the feature Mr.Side Chain, it's amazing for dance styles. In this video the guy has to play both hand for the Chord in order to get full range of the Mr.Side Chain works....But to me I want to add some sounds for the Right Hand to play the Intro or some Melody of the songs and keep the Left Hand for Mr.Side Chain Chord Progression , Can I do that and how can I do that?

Thanks
