V-Vocal to MIDI

I'm playing around with converting a vocal track to MIDI using V-Vocal.

Overall it works fairly well, but some non-scale notes show up in the generated MIDI.

Within V-Vocal itself, after applying pitch correction, all sung notes are scale notes (in this case A major).

When I click the convert to MIDI button and drag it to my MIDI track, there are several Bb notes which shouldn't be there.

Since I've constrained the pitch correction to the A major scale and the pitch correction is good with no Bb's, how do they end up in the MIDI output ?

Thanks Robin, but that doesn't seem to work as it looks like V-vocal is generating the MIDI from the uncorrected clip, even after correcting.

What I've tried with better success is to bounce the corrected V-vocal clip so that all notes are ok, then convert that to MIDI.
