As insisted in the reading, computers can act as "an extension" of the human during the music making process, and this can provide a valuable opportunity for the accurate, mechanical contributions of the computer to combine with an emotional aspect offered by human musicians.  Personally, I find that computer assistance is especially helpful when dealing with musical elements heavily reliant on timing.  For example, I like using a computerized drum machine or beat to can allow for impeccable timing throughout a piece.  A computerized beat creates the perfect background for a human musician to play or sing over.  Using a computer is more beneficial in some ways than others.  For example, using a computer for de-mutualization is beneficial because the computer can easily separate a human-created input from an output to create synthesized sound that can be worked with by the human interactor.   De-mutualization is also made possible by a computer because computers can work outside of the bounds of physical rules, and, in this way, the computer extends human capabilities beyond its natural boundaries. To be specific, the computer is a great mapping tool, as it can successfully bridge human created sound with the impeccability of the computer to create a unique output sound.
