Man, thats the name of the game! - Experiment!!!.......Jus try what fits yer mood that yer in at that moment would be my best advice....dont get hung up on what people say u should sound like, or what u think a typical rap beat should sound like, shit, thats how fools start soundin like other cats anyways....Jus go with the flow and feel it out...........Biggest thing is, if this is new to you - dont expect it to be a perfected artform from the git, trust me its not happening.....It takes time to find yer tru sound and what feels organic to u, whatever u do - dont rush it, just keep at it. Fuck what heard about this dude or that dude that mastered his shit the day he started!....Shit takes time to sharpen yer skills in anything. - Dont believe the hype.
But once again, IF yer beginning - try and not focus sooo much on what sounds are so critical as to rather try and start defining what yer sound is to begin with....Try and find those magic formulas that work for u so well with whatever equipment setup u have and then after that start focusing on that particular sound u want.....Trust me, things will almost fall into yer lap naturally at that point, becuase by then u will kno yer gear in and out and at that point - skys the limir, yer really only problem then is thinking of something u want to make since u got all the tools in front of ya.
