Unisons on sampled string instuments?

[rolomoto]

By unisons I mean notes with the same value. For example, the B below middle C (call it B3) on a guitar can be played on the 2nd to 6th strings. Each string will have a subtle tone variation.
How do sampled sampled string instruments take this into account when sampling the raw sounds and then mapping them to a single key on the keyboard?
I mean you could have 5 of these B3 notes on the guitar yet there is only one B3 note in the library and on the keyboard.
Thanks for any help if this makes sense.

It's not that subtle actually.
Me thinks in sample libs this can be catered for with "articulations".

Bowed strings often don't, though a few do. One thing bowed string players practice is string crossings while avoiding obvious changes in tone, and the tonal differences are not really used that much in classical music, though there are exceptions.

With sampled guitars, this is pretty standard, though, and is usually taken care of by selecting a playing position (often automatically taking care of the shifts with a manual override option) which then uses the appropriate sample for the note. Some will also have keyswitches for specifying strings, and some will also allow dedicating a separate MIDI channel to each string.

What he said
For example scarbee's basses uses "profile" to determine preferred strings (rock players prefer higher fret on lower strings, for example), but also use keyswitches to override it manually.
Also, not a sample libraries, but guitar pro use midi channels to determine strings when inputting notes through midi.

How do sampled sampled string instruments take this into account

Few do. VSL Dimension Strings allow you to choose the string you want, so you can get the darker tone higher up as you are indicating, et cetera. It seems like they have other products which do but I don't have them, you'll have to research it. They do make a distinction between bowed and fingered legato or slurs per se afaik.
