Joanne,
You've done a great job with this article. Kudos to you

For those who read your blog and don't have Melodyne, there is a feature in Realband that will also convert a single note audio melody to MIDI. It's found under "Edit | MIDI" and is called "Pitch to MIDI convert (current audio track)".
I've used this a couple of times over the years and it gives pretty good results. I don't know how it compares to Melodyne, though.
I'm looking forward to your next article now. I enjoy reading what you put together. You've got a knack for interesting writing.
All the best,
Noel
