I like my drums just a bit louder on the fills
And sometimes my fills may have a single bass note, held, which I want a bit louder
And maybe I want that bass, for that 1 note or run to be a slap bass instead of the finger bass on its "corresponding" arranger part
Or maybe I want a different drum kit because I like the toms of another kit, just for the break
Perhaps I just want a bit more reverb on my fills
Need more reasons?
Why must we conform to the "norm"?
Why limit our creativity?
