very cool i was just looking at a similar program Vocaloid
I'd highly recommend
SynthesizerV instead of
Vocaloid.
In my opinion,
Vocaloid has stagnated over the years, while
SynthesizerV is pretty much cutting-edge technology.
More importantly, you can use the Basic Studio and Lite voices in
SynthesizerV for free. The Basic editor has very few limits, and if you decide you like it, the cost is reasonable.
For example, you can buy the Studio version of the editor and unlock additional features, but stick with the free Lite voices until you feel like making more of an investment.
But - with all things musical - at the end of the day, it's a question of which sounds best, and is sufficiently easy to use.
Thanks for listening!
