Melodyne Converting Audio To MIDI Issue

The leaving all notes at one pitch thing, isn't that to do with having it set in percussion mode? (whatever it is called)

I just fired up Platinum and loaded up an old project, dragged a lead guitar part straight to a midi track and it all worked fine, notes as they should be and no lock up.
 
Last version of Platinum - Melodyne Studio (Latest) - Windows 10 Pro up to date

An interesting thing about this feature, I have installed Splat on a bunch of different computers. I have not done anything to authorize Melodyn. Yet this feature works. I had a little pitch issue with a vocal track and I did the regional effect to the little clip and Melodyn was not grayed out, and it opened the editor but I couldn't do anything? Oh well. I copied and pasted the same phrase from a different part of the song and moved on. When I closed Sonar later there was a splash screen that had been hidden behind Sonars window telling me I needed to enter a serial number. So It's weird how the audio to midi works without issue, It even creates a Melodyn folder. This is great because I really never use the pitch correction any how. And I do have V Vocal. 
 
But I do use this feature a lot and yes, you never have to create a regional effect first, just drag and drop. And I've never changed that setting obviously as I couldn't even if I wanted to. So far I've only got it to work with Bass Tracks. I played a little melody on a guitar and dragged it and it made a huge mess even though it was a few notes.. You know the little hook in Mother little Helper played on a ? Sitar?  Any how I had to do it t he hard way and used my keyboard. 
Maybe it only likes Bass notes. 

Ha! Only bass notes?

The other day it successfully converted a bass track but gwve timing only result for a monophonic guitar line.

Today it repeatedly locked up on a similar guitar track, but finally worked if i first made the guitar track a Melodyne region...

Yeah, I just think its a small bug possibly.....cause it doesn't seem to be consistant.

I'm actually really getting into the whole audio to midi feature, I recorded acoustic drums, and turned it to midi,,,,then turned that into midi bass and piano.....oh after dropping the midi note an octave or 2.......sounded phat az.........and then I converted lead acoustic guitar into midi piano, wasn't perfect, but was easily enough edited.......next, I'm planning on converting percussive funky Jethro tull style flute into midi, and then turning that into drums and bass????...I haven't done it yet, but I'm hangin to experiment with that

I sure hope it continues to work because it's become a Must Have  feature for me for making backing tracks. I can play a bass part in one or so passes and don't have to worry about precise timing or pitch. I don't even have to worry about what the bass sounds like!  I turn it into a midi track and takes a bout 10 minutes to edit and get sounding exactly the way I wanted it. Huge time saver as it would take all day to figure out how to play the bass line on a keyboard for me. 
 
I own a set of digital drums too, but we actually could just as easily set up some mikes on a bunch of cardbaord boxes and record that and use Drum Replacer to trigger AD2. 

So far I have only used it for Bass and it always works with only few minor edits to the notes. One thing that seems consistent is the duration is always longer than is should be. I select all and drag the duration back about a 1/32.   
 
It\s dead simple. Drag an audio track to a midi track. 
The interesting thing is this feature works on any of my computers running Sonar even if that computer is not authorized for Melodyn. I never use Melodyn for vocal pitch correcting so I haven't authorized it in years.
