One of a kind

I'm pretty sure this is the only app that does something like this. It doesn't state in the description very well but it's Auv3 capable which is great. A question to the developer, do you have any plans to add adjustable parameters? Just an ability to adjust the voice and speed, I'd love to use this in some of my music but it'd have to keep the beat.

Disappointing, could be better

There are no parameters or variables. No pitch, speed or voice change. Just the same voice. Also presets do not work. I can save them, but not pull back up. If i open it in aum, presets are selected, but none of the saved txt appears. I wanted to do a cool thing but it’s too tedious to use with having to type everything in every key every time. Fix this app!
