software with styles to be played live with midi keyboard

hi guys. i write pop music. i don't read notes, all by ears. i'm looking for a software with various STYLES (bass, drum, synth, whatever) where i can play the chords IN REAL TIME with my (hardware) midi keyboard. i find it a lot easier to find the right chords for my songs playing with full styles rather than just with a simple piano or guitar sound. software like garageband is waaay to tedious.
