Band Brothers P has a unique feature that can turn players into a Vocaloid. Players take a photo and use the 3DS’ microphone to record their voice. Then the game uses Yamaha’s Vocaloid synthesizer software and produces a Vocaloid for you.
Band Brothers P’s gameplay has been upgraded to support more musical instruments at the same time and the sound quality has been upgraded too. While Europe got Jam With the Band, Nintendo has not released any games in the series in North America.
