A number of the guitar VSTis use notes above and below the normal guitar range to add inflections, slurs, body hits, slides, hammer on pull offs, palm mutes. Also various strum modes and arpeggios are often done outside the range.

The Kontakt ones are different to AmpleSound which are different AAS Strum Guitar which is different to many other guitar VTSis but similar principles apply. A lot of the strumming VSTs have a “note” or “notes” to indicate the chord and another note to indicate the strumming pattern. The notes used to indicate a chord are not necessarily the actual notes of the chord. What I mean is a C triad might only require a C note a C7 might require a C and a C#. This varies with different instruments, Patterns can sometimes be created as in AmpleSound or adjusted to get what you want say in Kontakt.

Some players allow individual notes to be played for example, AmpleSound Guitars or Session Guitarist Picked Acoustic so melodies can be played other instruments allow strumming only.

It is amazing what you can get out of some of these VSTis but they do take time to learn and not all behave the same way.
