Sonar 3? I don't think it had audio snap or VVocal or Melodyne. 

i think he means x3 because his initial post said 8.5.

Attempts to convert polyphonic material to midi are likely to yield less tha ndesirable results.  For monophonic material the version of melodyne included with Sonar is a good option, especially how easy it is to give it a test spin.  dropping a monophonic audio clip on a midi instrument track will generate midi data

Lets hope so. LOL 

No trials, it seems.  i'll have to inquire about editor or assistant, prior to purchase.

actually, i do really need polyphonic conversion.....  and my x3 demo expired years ago!  not sure the melodyne audio-midi conversion was even part of the package then.

Celemony supplies their trial version http://www.celemony.com/en/trial. I do not believe it was included with the X3 trial.

And be aware, if you need melodyne to add pitchbend data based on vibrato in notes you need melodyne studio.

And also be aware that audio-to-MIDI is an imprecise science at best. As with any kind of translation, the simpler the source material, the more successful the translation.

Which is where melodyne comes in handy because you can edit stray notes and filter out harmonics. This aspect at a functional level is 10x better than the vvocal implementation.
