For someone with little-to-no musical talent (like me, for example), it's easy to equate the concept of "GH Tunes" (the "Guitar Hero" franchise's in-game music creator) and "Rock Band Network." Both offer ways for fans to get their own musical creations in the game. But Harmonix sees a big difference with what they're doing versus what "GH Tunes" offers.
At a preview event for "Rock Band Network," Caleb Epps, Composer and Sound Designer at Harmonix, talked about what he sees as a vast difference between the two products.
