Using loops is like sampling without having to dig(physically). I feel using loops and sampling is away to collaborate with other musicians to create a music composition. I'm not the best guitar player. Playing guitar on a keyboard does not always get good results. So chopping a guitar loop or sampling vinyl maybe be the best option for what I want to do. Is that cheating? I didn't play it. If the credits list me as the guitar player. Then yes I cheated. Other then that anyone listening to your music could careless if you played the guitar or not. If it sounds good is all that matters.
