How Rock Band 4’s new solo feature works — and how Harmonix made it happen

A new twist in Rock Band’s gameplay will likely throw even the most familiar players for a loop, and the way it works is like magic.

At first glance, Harmonix’s return to consoles with Rock Band 4 looks and sounds mostly similar to its predecessors. Note prompts rain down from the top of the screen while players do their best to keep up on guitar and drum controllers to some of rock music’s most popular tunes. Series fans will feel right at home — at least at first.
