If the individual views their "tool" as a crutch in the negative sense it is....for them only and the way they view others.

Sequencing allowed ANYONE to put in audio form a creation in their heads regardless of whether or not they could actually recreate it live. I don't view that as a negative....I view it as allowing more people to express themselves. Much of todays music is based on loops and sequences no one could play in tempo live...Does that make it irrelevant? I don't think so. The market doesn't think so. Joe piano bar guy does.But he is forced to cover those songs created by people who probably could not hold a stick to him technically.

Like PhotoShop allows for turning a mediocre snapshot with possibilities into a work of art, computers have opened up musical expression for those with little training and just like Arrangers have allowed a keyboard player to play drums and trumpet at the same time!!.
