I couldn't quite believe what I was seeing when somebody posted me this link.
It appears that there is now a program that can successfully analyse an audio file of an instrument playing chordally and polyphonically and break it down to its component notes.
Apparently it is now widely used a pitch corrector and mistake editor in the pop music industry.
It really is just like editing midi !
Since this is a very common theme on these forums - about converting audio to midi - I'd like to recommend these videos for people to watch.
I'd be especially interested to know what Mark and Sherry think.

go to 3:40 on this to be really impressed - the blocks on the screen are not (I repeat) midi, but analysed audio. Check out the video part 3 too.
You can download and beta test this product - see the info on the page.
