If anyone is interested in creating realistic human voices (using only free modules from the library, without using samples or external plugins), I invite you to watch my patch:
Thanks for your feedback!
I really love your angelic voices! I’ve used Pink Trombone myself in the past.
My goal here was to understand the mechanics of human voice sounds and simulate them realistically in VCV Rack from scratch.
So I set myself the challenge of not using existing dedicated modules (like Pink Trombone or Squinky Labs Formants) and only use free modules from the library.
