Meiko V3 is a next-generation singing voice synthesizer featuring a rich and expressive female voice suitable for various music styles, from rock to electronic music. This updated version of Crypton's original Vocaloid offers high-quality vocal samples recorded in a professional studio environment, resulting in a natural and lifelike sound. The package includes five distinct voice banks: four Japanese tones ranging from powerful and clear to whispery and emotional, plus an English voice bank designed for English-language productions. Each voice bank captures different moods and vocal expressions, allowing producers to tailor Meiko's voice to diverse musical contexts.

Piapro Studio, the included vocal editor, integrates seamlessly as a VST or AU plugin with major digital audio workstations, enabling efficient note and lyric editing through an intuitive piano roll interface. Users can manipulate vocal parameters such as dynamics, breath, and gender characteristics with ease, even while playback is active. The software supports importing MIDI files and allows simultaneous layering of up to 15 vocal tracks, enhancing creative possibilities. Exporting vocal parts as WAV files facilitates smooth integration into broader music production workflows.

Meiko V3 is delivered as a comprehensive production suite that includes the Studio One Artist Piapro Edition software, equipped with over 200 virtual instruments covering guitars, drums, keyboards, strings, and more. This synergy between vocal synthesis and instrumental assets offers a streamlined environment for composing, editing, mixing, and mastering complete songs. The package also provides additional tools such as Tiny Vocaloid3 Editor and exclusive sample content, empowering creators to produce professional-quality music with a distinctive vocal character.
