I have been looking for the vocalist wizard, but can't seem to find it?
I'm not aware of a vocal wizard in the Band-in-a-Box plug-in.
For 2019 Band-in-a-Box for Windows you access the Vocal Wizard by selecting: "Window" > "Lyrics" > "Vocal Wizard ...". More information about the Vocal Wizard is available in the 2019 Band-in-a-Box for Windows user's manual starting on page 383.
Geico insurance has a Vocalist Lizard?!
