OK...
 
Is this due to polyphony or some such?
 
I just easily dragged a bass track (audio) to a synth and it converted the part both pitch and timing...
Then I tried a monophonic (but stereo) guitar track (audio) and it only returned timing all on a single note...
 
Can someone explain what's going on?
 
I'm also guessing that I need to upgrade to Melodyne Editor (currently too expensive for me) to get polyphonic conversion or does it still not do Audio2MIDI for such?
 
Thanks!
 

When it returns timing on a single note, it means the detection algorithm is set to percussive.

But then why did it convert his bass track properly. I have experienced this same behavior. It works perfectly for bass, But I thought I'd create a midi flute part and played it on my guitar. It made a huge mess out of that. 
 
And I once tried to convert a snare drum audio track to a midi track and ended up with a bunch of notes all over the place even though I thought I'd changed to percussive mode. So it's just a bit buggy as far as I can tell. I don't care as long as it does the bass. I used drum replacer for the snare and that works great. 

Thanks...

Both of you!

I thought of the percissive selection but 2 minutes earlier it did a perfect melodic/timing conversion of the bass part. I undid the bass conversion, changed the patch in the same synth and dragged a single note (but stereo track) which got the timing on a single note a la percussion mode...

Something else involved here...
