We must learn all this also by taking courses or the methods provided for.
And, yes, Rocksmith is really useful, because it is a great way to practice the skills they are acquiring.
It is for me the main weakness of the software (I'm not talking about the game, because we are more completely in the concept of pure play): it is not as it could have been educational as it is not sufficient to itself for someone who has never taken guitar lessons or learned by other means.
Once accepted Rocksmith for what it is (not that for which he was promoted), we really appreciate the software. Technically uptake guitar signal (with the supplied special cable to plug into the output jack on the guitar) works perfectly. The tuner also allows the game to ensure easily.
Very nice feature: the difficulty (= number of notes to play) adapts in real time at the player in the score. Successfully several consecutive notes and you'll have more to play. Miss, and we remove you.
Attention to the latency of LCD TV: I first tried the game with a direct connection from my console to the HDMI terminal of the TV (Sony). I noticed a lag between when I scratch the rope and when the sound comes from the TV. I have since purchased a home cinema amplifier, which resynchronize the sound with the signal sent to the control (I think his fate "faster" of the amp as a TV). Ubisoft also recommends out the audio signal of the console with a terminal other than the HDMI connected to the TV.
The interface is simple (it is far from ultra-colorful and lively design of Guitar Hero), but effective.
In the end, original software, well thought out, useful accompaniment real guitar lessons, with a wide choice of quality pieces. If you are looking for fun music game, Rock Band or prefer Guitar Hero. If you are looking for software to perfect your technique, choose Rocksmith.
