yikes....I didnt even think about that.
All my beats you've heard use samples from songs I've chopped and stock sounds from logic. Twist some knobs in the es2 synth or watch a tutorial how to make a certain sound you like. Download exa24 sample packs too or you can create your own. And open logics 5 band eq on and instrument track and experiment with cutting random
Frequencies from the high and low end.
Also. Experiment putting the amp designer on different Instruments from the exs24 you wouldn't normally hear an amp on. Like horns and strings.
Also try layering sounds from the exs24 orchestral section to create epic sounds. And check out te synth leads in the exs24 too with amp designer on em. You need them waves plug ins. JJP Strings
they'll make logics stock strings pop
