With X1, R-Mix and Melodyne would not be included.
 
Even with Melodyne Editor, I played with this to see how well the polyphonic version could extract notes... and it wasn't the prettiest sight to behold.

Sorry to hear that part... I've been expecting miracles from it after all people talking about it... So if it's not for they polyphony, I guess the only other reason to upgrade Melodyne to full Editor would be the control of formant? I don't see that in the version given with X3...

Sorry to drift off topic...

I spent 30 days on a trial of the full-blown Melodyne, precisely to try to extract midi notes from a mixed WAV tune file, and after LONG hours of trying all kinds of isolation techniques for the various frequency ranges of the instruments, it just came out horribly, and I now firmly believe that unless the song is something like Chop Sticks, it is just not going to happen.
 
The Melodyne documentation tells you right up front that it is NOT designed for extraction from mixed files, and even with the polyphonic version, it tells you that you need access to each of the individual instrument/vocal tracks.
 
I agree with the other above posts that if the song is a cover of something already done, that there may well be an existing midi version out there.  I myself have found and downloaded literally several thousand midi files, most of which are of REALLY good quality.
 
Your other choice is to either figure it out yourself, (which I do all the time for hard to find progressive/fusion tunes), or hire someone to do it for you.
 
Good luck,

Keni - the Melodyne Editor DOES do a real good job with individual instrument tracks, it is just not able to do the same level of translation/extraction from a mixed file, as there are just too many frequencies all mashed together.

Hey Keni, there have been a lot of posts on Melodyne, but as with any program, it has its algorithm it runs to. The Editor is significantly more capable (i.e. polyphonic mode), but it is not by any means a panacea to catch each and every note that it hears. And in finished recordings (distortion, reverb, etc.), there are many artifacts or other notes that Melodyne will see as "discreet." They have a great video on why not to use the editor on a guitar with distortion... when you do edits, the "linkages" of the harmonics can be broken, and sound terrible. If you edit the clean guitar, then add distortion is sounds great.
 
Melodyne is very effective if what you are feeding it conforms to how its algorithms run, i.e., the cleanest signal possible in gets the best results out. For this it works extremely well.
 
My earlier post was from me "stress testing" things to see how much "could be done," and feeding Melodyne a signal laden with harmonics + effects on them is a clear "break point" for it. Feeding it a final mix was funny to see

Dear Friends,
When I was going to pose this subject, I was aware that, it is not at all an easy job! But I do not believe that it is impossible!
When I reviewed the Threads,two posts Drew My attention:
He had referred that, He was able to convert the file to midi tracks but the track result was horrible.
Excellent! You had reached to 50% of target.
  • The second one was mettelus Post  #15
He had described that, Melodyne is very effective. if what you are feeding it conforms to how its algorithms run, i.e., the cleanest signal possible in gets the best results out. For this it works extremely well.
Great! It is the next 50% of target.
Definitely, I am agree with the friends,who advised that, there are many Midi File available on net. Regularly I,  download myself many Midi file to fulfill my requirement.
But,
Let be some creative and Look at this project as a challenge There are many profissional creator and editor inside the forum. Lets do a team work and find an algorithm to "convert Audio/MP3 => GM 16 tracks" 
To start,
 Dear robert_e_bone,
can you please share your Project and your algorithm to say, how you was success to change your Audio file to midi tracks?
Dear mettelus,
Can you please advise your algorithm to show, how can we clean the signal to get the best result?
I also try to download Melodyne trial version (please somebody advise which version is more effective?)
Dear other friends,As ever, I need you great Ideas. And do not forget this fact,that just:
"Impossible" is impossible
Regards,
Ramtin

Sorry, but it cannot be done. period.

To do what you are attempting is not possible via any plugin or software that I am aware of. Melodyne is most effective on tracks where instruments are separated, and depending on computer, shorter passages rather than an entire song (Melodyne looks at the entire passage, not simply "time now" to process data).
 
To answer your OP, I have done what you are asking, but it is a very manual, and potentially tedious process:
 
  1. Put the audio of concern in track 1 and match the tempo of the song to fit that audio.
  2. Add MIDI tracks one at a time, and record them with the audio file as a template.
  3. Most passages in songs repeat, so that effort can be minimized by editing the required bars for intro, verse, chorus, etc., and copy/pasting to fill it in.
 i.e. Jeff Evans' post...

When you listen to the midi files that are available for a given song, the midi file is often fairly close but certainly not an exact copy of the original song. That, by itself, tells me that someone transcribed the tune as best they could into a sequencer.
 
The best results will come from hard work. Take the time to build the song track by track, transcribing each track note for note.
 
At some point in the future, I am 100% sure that someone will develop software to do exactly what you are wanting..... but I don't think that time is yet. Some things are approaching that point. Case in point is Melodyne Editor..... totally amazing piece of software but it still will not make that conversion to midi from the mp3 or wave of a song.

Ramtin, there is literally no way to do this. If you can make a program to create an accurate 16 track general MIDI file from a single audio file, you should patent it!! This is totally impossible with current technology. Maybe down the road, but not now.
