This is gonna be a short post (more like taking notes than an in-depth review!). Let's compare a few guitar VSTis!
First of all, Vienna Concert Guitar sounds bad and I think it's an old product as well. So, let's take that off the list.
Vir 2 Acoustic Legends HD
Amazing Sound. Great attack and clarity. Good body to the tone.
Nice fret noise while playing.
Have to create different channels for different articulations (no mode switching with keys)
Chords - Mediocre
Chris Hein Guitars
On the fly articulation switching with keys - muting, harmonics, hammer ons, etc.
Relatively smudged sound
Tinny tone, lacks body. (Almost as if it was run through an EQ or amp)
I compared both the instruments and their variations (nylon, steel, harmonics, banjo,...) side by side. These observations were consistent all over.
Chord strumming is one area where both of the heavy weights abover are lacking. MusicLab's RealGuitar has high playability and shines in playing chords and strumming. Not as good as an actual guitar, but can get very close results through clever programming. Sound quality is good as well.
For solos, I would use Acoustic Legends and for playing chords, RealGuitar.
Thanks for reading. Please leave your comments.
Update : Ample Guitar blows everything else out of the competition. Check this out. It sounds crisp and has a high playability too. Sounds very realistic. They have produced libraries for other guitar models too, including electric guitars. Check them out. Great job, Ample Guitar!
