Orchestral Tools offers SINE player and three SINEfactory orchestral sound libraries for free download.
This offer comes as an introduction to SINEfactory, a free instrument subscription service. We know the word subscription usually comes with a fee; rest assured, this one is on the house. Furthermore, the promise of more free instruments lies ahead.

Let’s take a closer look at each one.
SINEfactory Ratio
Ratio is a grand piano library that should impress even the harshest critics. The sound comes from a Steinway B grand piano, once played by Prince, no less.
The library has a very dreamy quality, which means it’s not the piano you’d use on everything. However, that ambient nature is stunning for cinematic scores, emotional pop songs, or even the right EDM track. It’s in the same bracket as Cinematic Soft Piano from Spitfire Audio, although Ratio is brighter.

A typical letdown of piano libraries is a disappointing low-end; they just don’t always translate the heavier hammers’ weight convincingly. While Ratio doesn’t offer booming bass notes, it does provide more than enough weight in context with the overall sound. Very impressive, indeed.
SINEfactory Gearbox
Gearbox is a collection of percussion sounds with various drums, congas, claps, and more. It’s not as vast as some of the most popular orchestral percussion libraries, but it’s free, and they aren’t.
The important thing about Gearbox is that I can comfortably say what it does; it does well. Gearbox is the unsung hero of these libraries; it doesn’t steal the show but does a lot of the heavy lifting.
SINEfactory Helix
Helix is a string ensemble taken from Orchestral Tools flagship Berlin Series. With free string libraries, a lack of instruments is rarely a complaint; it tends to be a lack of articulations.
The library delivers beautiful sustains and spiccatos, or in the most basic terms, longs and shorts. More experienced media composers might find that limiting, but it’s more than enough to create rhythm, harmony, tension, or any other quality your project needs. More importantly, it sounds more realistic than many expensive libraries.
SINEfactory – Free Download
All libraries require the latest version of SINE player (free); they won’t work with Kontakt 6 or any other player. Windows 10 and macOS 10.13 upwards are supported with a suggested minimum of 4GB RAM (16+ GB recommended).
SINEfactory is a genuinely valuable asset for any aspiring media composer. Get it for free via Orchestral Tools.
