There are plenty of other artistic mediums that lack a performance aspect. Painting, drawing, literature, photography. Do these mediums also lack soul because they directly connect the composer to the audience, without a third party to interpret? Sure, if a piece of music was written with the intent that it be played by human hands, then it probably won't sound great when played by a computer. But if an artist creates an original piece of music using electronic tools, how is listening to that piece any different than viewing a photograph, a painting, or reading a book? Many people dislike audio books specifically BECAUSE the filter of the narrator colors their interpretation of the author's words. As with reading, one might argue that electronic music better communicates the author's soul to the audience.
