How i can make akane and aoi (lite) voicebank 2nd voice?

I started using synthv few weeks ago, i saw akane and aoi on youtube and decided to download them. But they are one voicebank with 2 voices… how can I ‘enable’ 2nd voice in synthesizer V studio basic?

“Akane & Aoi” are only one voice. In speech synthesis software such as Voiceroid or AI Voice they each have different accents, but this does not apply to SynthV. For singing, there is only one voice.
