Oh markedymark, it does more than just vibratos and bends. It also does vibrato at different speeds, down/up/alternate pickings , slides up and down (at different speeds and from 1 to 12 frets each sampled individually), hammer-ons and pull-offs, sustains, staccatos, mute picking (tight, medium and loose, up/down/alternate pickings), trills at different speeds, harmonics (+/- vibrato), bending at different intervals and different speeds, various noises from the bridge/harmonic brush notes/release noise/scrape/stop noises, unison bend strings in various combinations, double bend, various chords at different strum speeds, and many more (too many to list) - and all these (each articulation) actually recorded on DIFFERENT STRINGS! Thats 150,000 samples.
And as soft said, with controllers, it's as easy as ABC. I'm sure you can pick up these articulations from the demos.
But one caveat - the many articulations also means it is quite different to be played live. To have the most realistic effect, one will have to sequence it. But once sequenced, and in a mix, it can replace LP players in a recording. But it is not going to replace a live player. So guitarists, don't worry too much...
Sorry pianoex, don't think you can play it live on an AX7...yet. Technology is changing and things will change in the next few years. Sample developers are now trying hard to make samples playable live, not just sequenced. It's already happening with violins and cellos. It's only a matter of time...
