I need help with Vocal Fry (Glottal Effects panel)

I’ve been a VOCALOID 4 user and I moved to Synthesizer V because of it’s realistic results and easy to use interface. I opened the glottal effects panel and used the preset “Vocal Fry”. So I played it and it sounded terrible. Can someone help how to use the “Vocal Fry” preset on the Glottal Effects panel?

Look this :slight_smile:

Ooh~ what are these?
