It does have a lot of problems though but right now I really dont feel like they define it due to it being so new. They do need to allow you to use at least V4 voicebanks though so your not limited to only Miku NT/cryptonloids/NT or whatever. Plus it still is gonna get updates so they'll most likely add in plugin support. It also shows exactly when the sound starts idk what thats called either. While its not got some godly feature it has a lot of quality of life features like it can load MP3 which can make things easier if you just download a vsqx and it has a off vocal mp3 but no wav. I see a lot of people hating on Piapro Studio but I'm 90% sure its gonna be the best vocaloid studio (Idk what to call them) yet.
