Dreamtonics - the company that made SynthesizerV - released Vocoflex today:

https://dreamtonics.com/vocoflex/

Vocoflex is described as a "real-time voice creation & transformation plugin", which makes it akin to RVC for voice cloning.

At $200 (currently $159 on sale), it's not exactly cheap, but unlike RVC it doesn't require a high-powered video card to run it.

But unlike RVC, it offers features like being able to create your own voice, or morph between voices. So there's a lot more flexibility in what can be done with it.

However, you'll need to identify yourself before you can use the software. That means providing an image of your passport/driver's license/national identify card/residence permit, as well as having a camera on your computer to verify that your face matches your identify card. If you don't want to give out that information, don't get Vocoflex.

You'll also need to make sure you've got a powerful enough computer. I can render tracks in my DAW, but I can't play audio back in realtime through the plugin, as it renders at 70% realtime speed with nothing else loaded in the DAW except for a vocal track and Vocoflex.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
