Template:Prima V2 voicebank

Prima is different than others as she is made as a professional Soprano opera singer. This means she can hit high notes with accuracy and ease and is considered amongst one of the more professional aimed Vocaloids. She is also the only Vocaloid 2 voicebank that can match Hatsune Miku on high notes and both tie for highest Vocaloid 2 optimum range at #E5. Also like Hatsune Miku, Prima is also capable of reaching notes that some real singers have difficulty reaching. She also has the largest optimum vocal range of any English Vocaloid 2 voicebank.

She has one of the most powerful sounding of the Vocaloid 2 voicebanks and favors long drawn out notes. Many consider her one of the most natural sounding English capable Vocaloids in the Vocaloid 2 range, if not the most natural sounding. Her vocals blend together fairly easily when used correctly and is one of the smoother English capable Vocaloids. She was also the first English capable Vocaloid with the ability to make breaths ([br1] to [br5]) and the only Zero-G Vocaloid 2 who can make them, she is also the English female voicebank with them besides Megurine Luka. As well as this, she is the first English vocaloid to have a thrilled "R" sound, which was added to make her mimick opera better.

She is noted to be harder to tweak into other styles and is grounded to her opera-esque style of singing. Prima was the first Vocaloid to have an improved engine, whereas Sweet Ann, Hatsune Miku and Kagamine Rin/Len had the same version of the Vocaloid 2 editor. Prima became famous for an issue related to the Vocaloid 2 engine, which would render the Vocaloid 2 editor unable to be opened when older Vocaloids were installed over newer ones. While she was not the only voicebank that encountered this problem, she was the first to show it and the only way to resolve it was to reinstall the newest version of the software over her software.

In December 2010, Sound on sound writer Tom Flint reviewed Tonio. While he did not review Prima, he raised some points during Tonio's review about the genre of opera based Vocaloids. Part of the issue related to Tonio's opera-based voice came with editing, and as quoted in statement on Tonio noted they "just sounds odd when coloured with an electronic effect". Flint felt that perhaps opera wasn't the best choice for Vocaloid, stating the issue is that the Vocaloid software makes it too robotic to sound natural and less useful.

There may be some issues with installing Prima on a 64-bit system as the installer for her software refuses to open on certain versions of Windows. According to Zero-G, installing Tonio then Prima will fix this. Prima works in Windows 7 in 32 bit mode.
