I have used my pc for midi for over ten years and have tried most software, including BIAB,Powertracks, and VanBasco. They all do the job, but Notation Musician or Composer has the most tools and best GUI for the money IMO. http://www.notation.com/Products.htm

I play midi tunes for singing and playing the actual score with muted parts.
