CeVIO Pro seems to have changed its name to "VoiSona", and will be releasing the beta version on June 2nd. The above Tweet also includes the official Twitter for VoiSona.
That's why I prefer when companies keep 2 options:I do love Sasara's newer design, and I'm excited to hear what might come out of VoiSona. I'm a little leery of any kind of sub service for something like this, which is easy to forget but which we must keep in mind, is an instrument. I'd prefer to just purchase one outright, even if it's a bit more expensive to give the voice actors more royalties. And also if you own something, then you can keep using it for... ever, really, even if you end up having to run an older version of your OS as the software ages. But for things like these, you lose access if you stop paying the fee or the company servers shut down, right?
...All that to say, I probably won't go for a subscription model of voice synth, not when I have SO many banks on other engines. I do wish them the best of luck though! I hope to hear some nice stuff from them in the future :)
