A fourth masculine vocal, commonly referred to as 'CV04', was being worked on, but has yet to be released, this was confirmed to be the last member of the CV series.ĭue to the series' success, additional vocals called 'Appends' were added for each character starting with Hatsune Miku Append. Initially, only 3 products were designed for the VOCALOID2 engine, 'CV01' ( Hatsune Miku: based on sound when it first begins travelling), 'CV02' ( Kagamine Rin & Len: based on mirrored or reflected sound), 'CV03' ( Megurine Luka: based on sound after it has travelled), all of which were voiced by female vocalists. Still, despite this, the initial target audience were professional musicians. The direction of the vocals was to be a more characteristic set of vocals, as KAITO and MEIKO were created to be more generalised vocals, using voice actors so that they could give particular vocal performances. The change of approach from using professional was due to the fact it was difficult to find professional vocalists who would lend their vocals to the VOCALOID™ software. Their vocal goals were based on how sound travels, hence the use of '音' meaning 'sound' in the names of the packages. Ideas formulated from Miku were continued into the rest of the series with each vocal having different stand out vocal qualities. Wat wanted far more attractive vocals from Miku then what had been previously provided, with more flexible results in terms of age and gender.

The VOCALOID vocals were often noted for their thick and ugly results and so when making Hatsune Miku, MEIKO was used as a baseline for what the series would achieve. The concept of Character Vocals was to produce a specific vocal quality, rather than to be professional vocalists like all past VOCALOIDs. It was the predecessor to the later Project if., however, the popularity of the Character Vocals has lead to the latter being repeatedly put on hiatus.

It is also the first set of VOCALOIDs developed by Crypton Future Media, with the character Hatsune Miku being officially the first Crypton Future Media VOCALOID. This intention was dropped when the VY series was introduced late in the VOCALOID2 engines time on sale, with those vocals taking over as the 'Standard' for VOCALOID2 onwards until VOCALOID5. The intention of the Character Vocal series was to take over as the 'standard' vocals for the VOCALOID2 engine and would act as replacements for the pair. The Character Vocals were the successor to the initial unnamed VOCALOID 'series' which consisted of MEIKO and KAITO, both of which were sold by Crypton Future Media, but developed by YAMAHA.
