Daigasso! Band Brothers P

Daigasso ! Band Brothers P  (大合奏!バンドブラザーズ, Daigassō! Bando Burazāzu, lit . "Grand Ensemble! Band Brothers")  is a video game created by Nintendo for the 3DS handheld system. The game is based on becoming a VOCALOID Producer, and totes a "Create Your Own Vocaloid" system using the 3DS's built-in microphone.

Engine Usage
This game is the only 3rd party VOCALOID application to use the VOCALOID3 engine instead of the previously used VOCALOID2 engine. The version used in the game is a heavily modified "lite" version of VOCALOID3, and uses a brand-new user interface. Unlike other VOCALOID applications, editing of the song data (such as lyrics, tempo, or pitch), is not allowed. The interface used by the game's engine bears resemblance to the interface used by VOCALODAMA (a game which itself uses the VOCALOID2 Lite Engine). The engine is operated in real-time during gameplay and is a core element in the game.

"Create a Vocaloid" Feature
In order to properly play this game, the user must "Create a Vocaloid" using the 3DS's microphone. The Vocaloid that results will be used in gameplay. However, due to recording limitations and constraints, the Vocaloid that is generated is low-quality. During the recording process, the 3DS will prompt the user to sing syllables in sequence. Only one pitch is recorded. The recorded sounds are processed using an audio alogrithm and compressed into a .ddb file for use in the game. Triphones are generated through the same algorithm. It is illegal to use this Vocaloid in any other VOCALOID engine, however it is mechanically possible to do so.

Usage of VY1
The game uses VY1t (a 'lite' version of the VY1 software) as both a background singer and default voice in the event a custom Vocaloid could not be loaded from the 3DS's software. Unlike the VY1t version used in the VOCALOID FIRST and iVocaloid apps, this version of VY1t is customized for the Daigosso V3 Engine.
