Audio to sheet music

I want to play or hum and record an audio track.  Then I want to create a midi track to follow the audio and pretty it up so I can print a reasonable looking score. 
 
Is there a tutorial available that leads me through the process?
 
Assuming no, the approach I intend on following is to make a groove clip from the audio track and define the downbeat of each measure.  Then tediously enter notes in a midi track that follow the melody.  Then use quantize and such to pretty things up as needed.  Unless someone points me to a more automated way to get the midi from the audio.

Finale can do this and it is more suited to making good printable sheet music.

Quantize will only work if the playing is a little off the beat, it won't fix a performance that drifted off time completely. 
I'm afraid if you need to play along with the metronome if you are planning on doing any midi editing and especially if you plan on converting it to sheet music. 
 

Thanks, Swamptooth, that's what I was looking for:  fit to improvisation.  Hard to look something up when you can't think of the name of it, particularly in a 2,000 page manual.
