Eventhough your BR-600 has a drum machine on it, it's top feature is the recorder/mixer. Banging beats on it is cool as a beginner but eventually you will definitely need to start doing your drum patterns in a DAW (like FL Studio or whatever). There you can really learn how to manipulate patterns and tweak them to sound more like real drums. For now, have fun with what you have, later you can decide if you want to go any futher with making music.
