Audio to Midi

You can do it with Melodyne.
 
Now here's the scoop. Do not expect much from a dense track. IOW, take a song form a CD and convert it to MIDI will yield garbage.
 
So the answer is to use a track with just one instrument and the cleaner the better. A bass track can sometimes work really well.
 
A distorted guitar track.... no so much.
 
A clean guitar track, yes under the right set of conditions.
 
The first condition is that you have Melodyne Editor with DNA. That will get the notes of chords separated.
 
The other major condition is the quality of the track.

I can drag an audio file in X3 and convert it to midi using Melodyne Editor, but for some reason it doesn't work in Sonar Platinum. Any thoughts?

Audio Chord Wizard of band in a box can extract the chords from a whole song,then use one of it`s styles to make your own arragment.
It`s very accurate even in complicated chords.
Peace
