After debunking the rumor that a keyboard peripheral was headed to Guitar Hero: World Tour, Neversoft has revealed to Shacknews that the secret is actually a feature -- not a peripheral -- that will allow users to transfer MIDI data to the game using a MIDI sequencer. So, in a manner of speaking, the new peripheral is whatever instrumentyou want. At least, that's the case for the PS3 version of World Tour, which will allow users to transfer MIDI data to the drum, guitar, keyboard, bass, or drum tracks. The 360 version, unfortunately, will be limited to the drum track thanks to "hardware issues." Well crap.
Still, Neversoft's Brian Bright informs Shacknews that the feature isn't something that most World Tour players will utilize, saying, "it's going to take an FAQ on the Guitar Hero site--it's not something that your average user is gonna do." Geez, you'd think composing music on a PC and transferring it to a game console via a MIDI sequencer would be a snap.
