The lead designer on Rock Band 2 says that Harmonix wants to let gamers create and share their own music, but wants it to be "an authentic experience".

We spoke to Dan Teasdale at a recent press event for the forthcoming strum-em-up, and asked him what he thought of the music studio included with Guitar Hero World Tour. The developer said that he hadn't had much time to play with the tool set, but that he had noticed a number of restrictions.

"We've dabbled around with stuff like that before, with Frequency and Amplitude, and we learned a lot of lessons from it," he said. "The main one is that you can't do it half-arsed. If you want to do a way to let players create and distribute music, you have to go all-in - not just do it as a bullet on the back of a box."

He added: "We actually want to find a way to for people to create music and express themselves, but when we do we want to make sure that people can sing, or the songs can be longer than three minutes, or that you can have more than 1200 notes, or that you're not tied to some dodgy sample somewhere. We want to make sure it's an authentic experience and it fits on the platform."

Teasdale also noted that he was looking forward to seeing more of GHWT's music studio once he's finished promoting Rock Band 2.
