Firekorn, thank you for such a comprehensive response. I agree completely that UBISOFT can't twist an artist's arm to make even a stereo mix available, let alone track stems. I'm aware there are too many variables and legitimate concerns at play to 'blame' UBISOFT for that and you outlined some of those concerns in your response. Of course when it comes to early Beatles material, as an extreme example, one-instrument-per-track stems don't even exist anyhow. I must say, though, it is still tantalizing to fantasize about the availability of original studio tracks as stems (where they exist) when you listen to some of the more-or-less isolated track stems on YouTube for something like 'Layla,' for example. When you think of the average cover song performance scenario, you're typically talking of a bar band / patio band type situation where you simply can't perfectly replicate the song in precise detail anyhow due to instrumentation among other factors. That's why I think using the track stems of cover versions of classic tracks doesn't compromise much and there is the benefit of knowing the only guitar you are hearing as you play along (and record) with the track is yours. It's just my opinion, but I think playing along with even a turned down song that contains the guitar part you are playing tends to mask your own playing and, psychologically, you might then credit yourself for playing better than you did, ha, ha. That's how I feel anyhow when I hit play on an original track in a media player and just play along with it. I realize RS provides visual training cues and learning tools, etc, and there is a fun game-play element but, at the end of the day, you are playing along with a song that already contains the part you are (trying) to replace. That's how I feel about it, but I realize no-one else is obligated to feel the same. My comment about being tethered to RS on a computer wasn't a negative judgement on my part that RS has no value as a training tool or as a memorization aid. It was a comment about the potential psychological effect on a young learner, specifically, of being connected to a computer while they practiced and played. Would they subsequently feel naked trying to perform the song without the support of the visuals and a subdued but still present original guitar track? That's what I was alluding to there, but I didn't flesh it out. Session mode seems interesting, but it's a first generation feature isn't it? Well, RS is not a major outlay, so I think I'll get a copy and play around with it for a while before I decide whether to introduce my son to it. Maybe I'll get hooked on it, I don't know. I have to admit I'm curious about the custom downloadable content . I'll give it a shot and report back at some point. Thanks again, Firekorn.
