Decide Wet or Dry Before Anything Else
This is the choice that decides whether a library fits your template, and it is the one buyers think about last.
A wet library was recorded in a scoring hall with its ambience captured, and it sounds finished the moment you load it. That is the appeal and it is also a commitment, because the hall is baked into every sample and you cannot take it out. Two wet libraries recorded in different halls will never sit together properly.
A dry or close-recorded library arrives sounding thin and unimpressive, and gives you the ability to place it wherever your reverb says. It costs you an afternoon of setup and it buys you a template where everything shares one room.
The practical rule is to pick a lane and stay in it. A composer whose library shelf is half wet and half dry spends the rest of their working life trying to reconcile two halls, which is the single most common reason a large template sounds like several orchestras rather than one.
Buy the Legato, Not the Articulation Count
Product pages sell articulation counts because they are easy to print. The number tells you very little about whether a library will hold a melody.
Legato is the expensive part of a string recording, because every interval has to be performed as a transition rather than as two separate notes, and the number of combinations grows quickly. A library with forty articulations and mediocre legato will disappoint you on the first exposed line, while one with twelve and a beautiful legato will carry a whole cue.
So audition the legato first and ignore everything else until it convinces you. Play a slow melodic line with wide intervals, then a fast one with small steps, and listen for whether the transitions sound like a bow changing direction or like a crossfade.
The friction is that demos never show you this. Demo tracks are written to flatter the library, so the intervals stay in the range the sampling handles well, and finding the edges requires a trial or somebody else’s honest walkthrough.
Check the Section Size Against What You Write
Cinematic covers section sizes that sound nothing alike, and the word tells you nothing about which one you are buying.
A full section of sixty players has weight and inertia. It cannot move quickly, it blooms rather than starts, and it is the sound of a main title. A chamber section of around twenty has definition and speed, it articulates rhythmic writing cleanly, and it is what most modern television underscore actually uses.
Buying the wrong size is a common and expensive mistake. A large section will smear a fast ostinato that a chamber section would nail, and a chamber section will not deliver the wall of sound a trailer brief asks for.
Where your writing genuinely needs both, that is the honest argument for owning two libraries rather than one, and it is a better argument than any difference in tone. Our chamber strings roundup covers the smaller end.
Know What Is Missing Before You Buy
Two things are absent from more string libraries than you would expect, and neither is prominent on a product page.
Second violins. Plenty of libraries record firsts, violas, cellos and basses and leave the seconds out, on the assumption you will transpose the firsts. That works until you write real divisi, where two lines built from identical samples phase against each other instead of sounding like two desks.
Divisi patches. Recorded divisi, with a genuinely reduced player count, is rare. Without it, dividing a section in your DAW stacks two full sections rather than splitting one, which is louder and thicker when the point of divisi is thinner.
Check both against the writing you actually do. If your string parts are melody over sustained harmony, neither matters. If you write counterpoint across desks, they decide the purchase.
What to Buy First, and What to Add
Buy one library that does sustains and legato well, and resist buying anything else until it stops being enough.
That library is the one carrying every emotional line you write, so it is worth paying for and worth learning properly. Shorts, runs and effects can wait, because a cue with beautiful sustains and adequate shorts works and the reverse does not.
The second purchase is decided by what your first one is bad at rather than by what looks exciting. Most composers find it is shorts and ostinatos, some find it is a smaller section, and a few find it is a solo instrument for the exposed moments. There is a roundup behind each of those three.
Buying in that order also spreads the cost across the sales that this category runs constantly, which is worth more than any individual discount.
