Thank you! People like you are the reason I shared my project, I hope you get to enjoy many more music in novel pitches and speeds. As for the request, very interesting, I will need to do a bit of research and see if I can implement it.

I just did some preliminary look-about and I see how it might benefit the program. I will try to implement it. If I do, I will edit this reply to tell you I have.
EDIT:

I have added the formant shift function you wanted. As soon as Version: 2.3.3 goes up, you can enjoy it to your hearts content. I hope it makes your day. I am glad you showed me this function, I never knew it existed before, not even in FL studio. I appreciate that.
