Acoustic guitar sound

Thank you for your reply. I will look that up

Guitar is probably one of the most difficult instruments to "emulate" via a computer based plugin.... the reason is simple: Both the player's hands are in direct contact with the actual, vibrating strings.

This creates a literally endless array of parameters, or "options" that the player has at his disposal. Not even considering such "extended" techniques such as slides, bending, (so-called "natural" or "artificial") harmonics, etc etc.... you have to take into consideration, on a per-note basis, of such factors as: angle of fingernail/pick attack onto the string, which will NEVER be consistent from one note to the next, no matter how "good" the guitarist is. Different degrees and intensities of palm-muting: this one i didn't mention in the above list of "extended" techniques because it's just infinite: multiply the number of possible palm muting positions by the number of possible palm-muting intensities, and already you have a very, very vast array of stuff you have to cover here. And the list goes on.... spicatto, rest strokes, free strums, which all sound different, the aforementioned nail / pick angle -multiplied by- depth of nail / pick attack onto string, and (in case of classical guitar) length of nails - yes, this DOES give a very different sound, the ratio of nails to fingertip hitting each string has a great impact .......... and we're just scratching (hehe) the surface

True, in the case of electric guitar, much of this is "drowned" or lost, as more distortion is used... BUT:

With even the best, ideal well tuned-up piano, there's only (by pianoteq standards) 127 ways you can play a single note. (ok, to be fair - without counting note-off velocity) But midi doesn't even come close to considering all the parameters you'd need to realistically reproduce any kind of guitar sound. There's just too much to take into consideration - midi wasn't designed for this.

And (in my personal opinion) violin and such stringed instruments aren't very far behind - since only one hand is in direct contact with the strings: the bowing hand however, still has several parameters at its disposal.

True but try the GS-2 demo, comprehensive intuitive editing that addresses many of the facets you mention, of course each has the "Learn MIDI Assignment" feature as well so with a proper controller and a LOT of practice... well, GS-2 is very nice
