Hopefully, it doesn't end up with SynthV becoming the monopoly. Some SynthV fan are really pissing me off with their constant whining that X Character is not on SynthV and now they're are overjoyed to see more companies potentially abandoning y synth program for their choice.
(Edited a bit cause of typos and cause I wanted ot add a couple of things)
I find this incredibly unlikely since not only we still getting new banks for other engines but most of the sv ports we got all had their own circumstances:
- Stardust Infinity happened both cause their other charas were already on the engine making it more convenient and cause they really really wanted to get away from their previous distributor (as far as I know).
- Haruno Sora is a character fully owned by ahs who basically strong armed themselves with SynthV so it was kind off more a matter of "when" than "if"
- According to an interview I saw Twindrill first took interest in SV when Tsuina-chan's team suggested it to them. That and allegedly they tried to port Teto to vocaloid once but she apparently sounded too different.
-With Xia Yu Yao it was more likely the limited options for Mandarin Chinese ai based voice synthesis at the time. Like it's either SV or Ace Studio (well there is Cevio too but Cevio does not have any Mandarin Chinese language voices and has more of an audience in Japan.)
-And now with KAFU it mostly just seems to be a cross platform availability thing. Apparently there was actual lore foreshadowing for that.
Like SV has def gained more of a market relevance thanks to Teto's success (which itself is a bit of a miracle to me given how fandom typically recieves different iterations of voca characters) but I doubt they can truly gain the market monopoly that vocaloid had/still kinda has in Japan mostly thanks to Miku and co. Vocaloids monopoly primarily stemmed from the fact that it was the first and for while
only commercial vocalsynth (that people actually heard of). That and Miku and co's ridiculous levels of popularity. That's not something any engine can replicate easily. Like it took Cevio Kafu existing to take off the way it did, and even then she's still eclipsed in popularity by Miku. Like, I wish I had that graph on hand now, but someone made a piechart of all the voca characters who's tags showed up in the latest VocaColle event on NicoNico and while Kafu made a very respectable dent in that chart, Miku was still almost half the damn circle. Unless they somehow manage to get the Cryptonloids on SV (which I am very press x to doubt on since CFM made it clear they have not much interest in pursuing realism for their voices so even if we get AI banks for the gang in the future, it won't be SV) they will
never have that market dominance. (Actually even if they did I still doubt it would change much most producers seem to prefer how their vocaloid version sounds.)
Side note, but it's a bit of a pet peeve of mine when people describe a character getting a new vb on a different platform as them "moving engines". Imho that's only really true if their company has stopped retailing/updating their other versions, which is only really true for Stardust out of this lineup. And even with her it's apparently moreso because Quadimension could not figure out how to restock her vb even digitally (as far as I know because of some licencing reasons?) so they decided not to bother.
