Just FYI : optimum Tempo and optimum Range is more like a suggestion from manufacturer, not the actual capacity of the VBs. So the tempo and singing range is kinda irrelevant in real scenario.Here’s a take: I do really (mostly) like the Crypton English banks. Miku is hit or miss, but when used well it is really good. (not you V3 English. you suck) Luka’s English is decent, not phenomenal, but good enough to not be incredibly hard to understand. Rin English is meh. It’s not the worst, but she is muffled and strange sounding. Len English is not good. Kaito English can sound like Kermit if not tuned properly, but personally I don’t really hear it. Meiko English… god it’s pretty but her tempo and range are garbage. B2-B3 for vocal range, and 100-130 FOR TEMPO RANGE. That‘s terrible. Still very pretty though!
