Rocksmith discussion thread - New real guitar game.

[hakko504]

Due to demand, they're going to release a Bass-mode as downloadable content a little while after launch.

Source?

If it's true then I think I just got a huge step closer to owning the Axe!

the bass support would be nice. then they can say (truthfully) that this is the first game to work with a real bass guitar.

I know what you mean, but if taken to court over it (false advertising), Ubisoft would be forced to stop using the claim "use any guitar" because that's already demonstrated to be false. I do agree with you that it's the first console game that only works with a guitar and not with a controller for the core gameplay, but even then the game allows you to use a controller to map butons to effect pedals. Deceptive advertising aside, I'm a bit interested, but I won't drop $80 on it unless it turns out to work really well and they release DLC I'm interested in.

i don't know that a court would actually find that to be false advertising. courts are pretty lenient with what they'll allow companies to get away with in advertising these days, making general blanket statements won't get you in trouble as much as making very specific untrue statements. and since most guitars will work with game, and most guitars that won't work with the game (namely acoustic guitars) can be made to work with the game by attaching a pickup, they'd probably get a pass.

i'll be taking a pass on this initially because i'm pretty sure the audio lag issue would affect me too much to be able to enjoy the game. that plus the wonky notation. i wish i could rent or borrow it to try it out and see how bad the lag is, but due to the proprietary cable that probably wouldn't be possible either.

Didn't somebody say that the lower the note the more lag? Won't bass really be affected by lag?

it's an interesting question. first, it depends which type of lag/latency you're talking about: software latency (the ability of the software to recognize what note is being played) vs. audio lag (the difference in time between when you play a note and when you hear it back).

it takes at least a full cycle of the sound waveform for any software to be able to recognize the frequency of a tone. the fundamental of a low E on the bass is about 40 Hz, or 40 cycles per second, so it takes 25ms for the waveform to go through one whole cycle. therefore, any software will take at least 25ms before it can recognize the lowest bass note playable (i'll assume they're only supporting 4-string basses, so no low B notes... might have to go slightly lower if they're including basses tuned down to D). that's a pretty significant lag, however, it seems like rocksmith's scoring system doesn't need to analyze waveforms in real-time to generate accuracy scores, so 25ms of lag may not be an issue as far as gameplay.

audio-wise, it depends on how rocksmith is generating the guitar/bass sounds. presumably they are just doing an A/D conversion, doing some digital processing, and spitting the audio back out. it's no different than how any other digital audio system does sound processing. there are plenty of bass effects pedals that do A/D conversion, process the audio digitally, and D/A convert back out the other end to an amp, without any noticable lag. so i wouldn't expect the audio processing in rocksmith would have a problem with that. also, audio lag with bass is not as much of a problem. most people can't hear down that low in frequency to the fundamentals of the lowest bass notes, and a lot of audio systems can't reproduce frequencies that low without a subwoofer. when you hear a bass, you mostly hear the higher harmonics and "feel" the lower frequencies, and your brain kind of puts it together in a way that you interpret as bass. also, just as it takes 25ms for software to recognize a low E, it takes your brain at least that long to recognize the note as well. the way we hear and experience bass frequencies, lag is not as noticable as it is for higher frequencies. that's also why we have a harder time determining the direction of bass frequencies as opposed to higher frequencies (and thus why you can place your subwoofer in almost any location in a room and won't notice the difference). because of that, the audio lag might actually be LESS noticable for bass than it is for guitar.

[RRhoads]

Can you explain that please?

What I meant is that it is not the real part of the guitar you are using. You are using the sensors in the neck, and you can't hear what you are really playing. So in a sense, Ubisoft are right to say that it is the first game that is played with a real guitar, if you look away from freeware games for the PC.

[PowderedToast76]

I've seen them constantly claim to work with "any real guitar", and even that is a lie because they already said it won't work as intended except for 6 string electric guitar.

There's no reason why you couldn't play this with a 7 string guitar. You'd just be using only 6 strings.

Thank you

Cant figure out the confusing notation at all.
What are they thinking
Guess you have to go thru the tutorials to understand
