Yeah, we know what you were thinking when you saw Harmonix's new downloadable effort, Rock Band Blitz : "Hey, this looks a lot like Frequency and Amplitude ."

After all, the plastic music instruments are gone and you're once again switching tracks and hitting buttons on a standard controller to play notes. But according to Joystiq , it'd be a mistake to call Rock Band Blitz a "cover" of any of the developer's classic PS2 music titles.

Firstly, there are only two tracks to follow in each song (rather than the five we had in Rock Band and Amplitude ), and there's also only one difficulty level. Secondly, missing notes won't kill your score multiplier; it's "additive only," in that every time you successfully complete a measure playing a particular instrument, that instrument's multiplier rises. In the aforementioned older titles, successful completion of a measure would result in the "locking" of that track, meaning the instrument in question would continue to play by itself for a while.

But the locking is gone in Rock Band Blitz , which means you can play the same instrument throughout an entire song if you so choose. This should offer you more freedom despite the fewer number of tracks in each song. Personally, I loved those old PS2 music games and I'd actually prefer playing with the regular controller, so I'm looking forward to this one.
