 Posted: Thu Jun 19, 2008 10:17 pm Post subject: How does Rock Band filter out other drums? |
 |
|
I was playing Rock Band today and I thought "I wonder if this drum will cut off if I stop playing it." So I stop playing the snare on a song I was playing and the snare actually stopped playing while the other drums where still playing. So I just want to know how are the drums recorded? Do they use some sort of audio filter to mute other drums?

There are 9 channels in a PS2 Rock Band file, and 13 on the other consoles. So what it does is there is more than 1 drum track, and the snare, tom, etc all have their own channels. When you miss the note, it cuts that channel.

Oh ok thanks. Wow I knew Rock Band drumming was complicated... but I didnt know it had that much processing and stuff involved.

Meh, pretty simple. It's just streaming a bunch of OGG files. Ram is all that really needs. :P

| Actually it's not so standard, one of my recent surprises recently is the variations in track numbers, the game engine can clearly handle quite a lot of variation. Drums can have like 2,3,5 different tracks (possibly more). I am work so I can't double check which tracks have the most (I want to say the recent Disturbed tracks though) like 3 pairs of Stereo tracks. I think the minimum is 2, Gimme Shelter has 1 mono track of Drums (+ Güiro) duplicated to create a Stereo pair. |

In the PS2 version, the songs.dtb file tells the game what tracks to use for what part. By standard it's
0-3 = Drums
4 = Bass
5-6 = Guitar
7-8 = Vocals (8 is a singalong track)

| Yeah sounds like the PS 2 version is stricter, more like what I expected all around. |

There's quite a few that vary slightly from the "standard" though, even on PS2, especially 70% practice tracks and _short songs for solo vocalists, but some others too depending on what masters were available in stereo etc. It probably can't handle many more simultaneous tracks due to CPU power, RAM, space on the disc, disc read speed etc.
And the full non-PS2 version with OGGs varies a lot and some songs have LOTS of tracks. I wouldn't be surprised if it was capable of full stereo tracks for each drum part, so 10 drum tracks! You'll eventually reach the limit of the engine/system and it won't be able to play back enough tracks I guess.
Back to talking about drums, some of the master tracks used for the game didn't have every necessary drum recorded on separate tracks and so they couldn't be separated completely for the game. You'll hear this on some songs, especially older ones. |

| Yeah looking at the Disturbed tracks they are 3 pairs of (apparently) real Stereo tracks for the drums. |
