I did some testing and got the Vocal Wizard to work. For my situation (if the vocalist is not very knowledgeable with BIAB) is is probably best for me to use BIAB to run the Vocal Wizard myself and send the .wav file tracks out in the key the vocalist needs. Here is the whole process including how I work around BIAB not using the "International Standardization Organization (ISO)" pitch standard.

Get the vocalists range in the ISO standard suggesting they use one of the tuners in the list in post #1.
Place the vocalist's range in my database so I always have it but document it in combo ISO and BIAB format. Example below.
SoAndSo's range is (A2-A3) to (C5-C6) where the 1st number in brackets is the ISO Standard & the 2nd number is BIAB.
When they request a song I enter the BIAB range in the vocal wizard.
I press the "Transpose now" button which appears near the bottom of the vocal wizard.
I close down the Vocal Wizard and reopen it.
Near the bottom in the black background section it will tell me if I have to do a "melody only transpose".
If it says I need to do this I close the wizard and do a "melody only transpose" then open the wizard again.
I do a final check of the bottom black background section to be sure there is no melody transpose suggestion.
If there is no suggestion I am basically done.
However I might want to analyze the vocal wizard upper messages to see if the key can better be centered.
If this is the case I do a manual judgement adjustment to the whole song so the vocalist does not need to reach to their extreme range note.
The whole process is finished so I can now send the tracks out as .wav files for the vocalist and other club members to work with.
The vocalist may use the midi melody to learn the tune by ear then apply their own style.

So why is the wizard requiring a two pass process. I think it is because it figured out if the first pass needs to shift the real tracks up or down to minimize the real tracks adjustment distortion. It does what it has to do and at least tells you that you have to take a second step to adjust the midi melody up or down by an octave.

If the vocalist is really good with BIAB and wants to do this themselves they could get their range by singing directly into the BIAB guitar tuner with a mike. Otherwise they can use their favorite tuner, figure out if it reports using ISO standard using the ISO standard pitch table also shown in post #1 and keep a record of it as I do with the same format I used "Example: My vocal range is (A2-A3) to (C5-C6)".

I still prefer that BIAB has the option to use the ISO standard. Like I said before BIAB not having the option to use the option to use the "International Standardization Organization (ISO)" music pitches table is like trying to sell a shiny new Bently car with a big scratch on it.
