i have both v4 and v6 editors (all from hatsunemiku.download) and normally v6 can open v6-5-4 and 3 voicebanks. but whenever i install an v3 or v4 vb it only shows up at v4 editor and i want to use them in v6 bcuz its easier. How can i open these at v6 editor? my vocaloid4 is 4.3.0 and my vocaloid6 is 6.12.0 (the non charactered ai voices like haruka allen etc etc are working)
