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.
Your premise and your conclusion is entirely unconnected by any form of logic.
The point of the post you reply to is that art can be created even when it is not possible or meaningful to do it as a live performance. Performers do not have a monopoly on creating art. In fact, sometimes performers are props that are or have been necessary due to the lack of technology.
Music does not exist until the moment it is played.
Therefore you need the performance to create art out of a composition.
Computers can not create art.
I don't agree with your premise. The composition as much art, often more so, than the performance. For most of the music I listen to, including the classical music, I want the performance to be a faithful reproduction of the intention of the composition. For sheet music, you need the performer to interpret, but if he or she interprets outside of well established norms, the piece will sound off.
For electronic compositions rendered directly to a sufficiently precise format (which MIDI is not), you need no separate performance - the act of composing it and performing it is the same.
Since I reject your premise, your conclusion is irrelevant to me, and I don't think there's any chance we will get any further.
I see from other comments that you imbue the touch of a human performer some special quality beyond the qualities purely physical sound generated, and to me that is pure superstition with no basis in reality. You might as well try to convince me fairies are real.
