Here's some beginner advice

so I know you're using FL Studio. i can easily tell from the samples from the 1 legacy pack in there. theres a thing called a VST (virtual studio technology) and there are in fact many packaged with fl studio demo as well as online...click on one of your channel boxes (ie kick, snare, clap) and click insert, then select a vst (preferably sytrus or autogun to get started). now you can do so much more with your songs! keep workin on it
