hit fruity loops up it's prolly the easiest to do with a learning level.
when you get into it you can pick up more advanced beats and move on to sampling other sounds into it.
over all I think it's one of the best beat making programs, withotu have a ton of samples..... which I do but mainly for Reason.

I keep Fruity Loops kinda simple, I usually make my beats out of a few different beats I make and end up blending them into something like this.
