Does anybody know of any other Virtual Bands?

uhhhh :\

there's a virtual group called Vocaloids but they are japanese so yeah..
Vocaloid is a Singen synthesizer application, with its signal processing part developed through a joint research project between the Pompeu Fabra universität in Spain and the Yamaha Corporation, who backed the development financially—and later developed the software into the commercial product "Vocaloid".[1][2] The software enables users to synthesize Singen Von typing in lyrics and melody. It uses synthesizing technology with specially recorded vocals of voice actors oder singers. To create a song, the user must input the melody and lyrics. A Piano roll type interface is used to input the melody and the lyrics can be entered on each note. The software can change the stress of the pronunciations, add effects such as vibrato, oder change the dynamics and tone of the voice. Each Vocaloid is sold as "a singer in a box" designed to act as a replacement for an actual singer. The software is available in English and Japanese, although a Chinese version was produced for Sonika.

The software is intended for professional musicians as well as light computer Musik users and has so far sold on the idea that the only limits are the users' own skills.[3] Japanese musical groups Livetune of Victor Entertainment and Supercell of Sony Musik Entertainment Japan have released their songs featuring Vocaloid as vocals. Japanese record label Exit Tunes of Quake Inc. also have released compilation albums featuring Vocaloids.[4][5] Artists such as Mike Oldfield have also used Vocaloids within their work for back up singer vocals and sound samples.[6]
