I'm very new to utau. I downloaded Hoshino Hanami voicebank and I'm kinda not satisfied with her default voice. I opened her folder and saw this, so I listened to these samples and I like Soft C4 the most. The problem is how I can use it? I really don't know. Thank you so much.
In the ust you can add a suffix to the note to get a specific recording set. To find out what characters are used for the suffix you can look into the voice configuration window (CTRL+g).
