V2; 1 voicebank V3; 6 voicebanks V4; 10 voicebanks

Note every update to Gumi has seen tweaks such as cleaning of the vocal, the original V2 was pretty LQ due to some tough background noises. Also the numerous voicebanks for Japanese are likewise because of another issue the V2 version had, which was resistance to alternations of tone. You couldn't get Gumi to sound different without some extremities. Its also one of the V2 vocals known for its collapsing tones, which is often common in modern vocaloids.
