Lord of the Rings Online players: Turbine is making improvments to the music system come Update 15.
"This system has such a net positive effect on the game, and more importantly on community, [that] it was long overdue for some developer love," the team posted. In the patch for sure are adjustments to the music system's pitch, volume, and balance, as well as a tuning pass.
Turbine also is toying with adding two additional instruments, the string bass and serpentine, although it makes "no promises" that it will be able to do so. Another stretch goal for the update is player-spawnable stages.
