Is there a video that compares the male voices? Preferably singing the same song. I have searched this forum and Youtube but cannot find anything.
I would like to see that as well.
There are many demonstrations of vocal modes here, all using the same lyrics: https://www.youtube.com/playlist?list=PLKvcxiPA-PCyXYedIwb16PYwEUhIQDnn7
The SynthV wiki also posts solfège demonstrations for each voice database and each vocal mode, at the bottom of the respective page: ASTERIAN (Synthesizer V Studio) | SynthV Wiki | Fandom
