Hybrid Tools Eternal Darkness overview

Hybrid Tools – Eternal Darkness is a focused collection of unsettling, dark and hauntingly beautiful horror-based trailer sound effects, featuring the expert sound design team from our critically acclaimed Hybrid Tools series. Based around 15 custom and slightly unsettling pieces of music, Eternal Darkness is designed to make the hair stand up on the back of your neck. Making this stand-alone collection perfect for scoring your next thriller or leaving your audience perfectly on edge. 

Eternal Darkness contains hundreds of freshly designed sounds, from processed vocals and synthetic-based haunting risers, to fully host synchronized patterns and pulses, to dark and insidious impacts and boomers. Each created using pure acoustic recordings and further processed through a variety of analog gear, leaving you with an organic yet gritty tonal quality. 

Each of the 13 carefully categorized banks contains a handpicked selection of expertly designed sounds, selected to both enhance existing pieces as well as to inspire brand new tracks. 

We have also split each core bank into Individual Songs, chosen to complement one another in both key and tone perfectly. 

Hybrid Tools – Eternal Darkness includes our fully rendered Hybrid User Interface with a variety of useful controls, including a fully functional  Sequencer, Tempo Synchronized Gate, Playback Direction Control, Speed Control, Pitch Envelope, Sample Offset and Randomization – all accessible from the main interface. You can also go deeper into our Chaos FX and control everything from Filters, a 3 Band EQ, Stereo Delay, Bit Crusher, Distortion, Dual-Convolution Reverb and an array of tempo matched Textural Convolution pulses.  We have also prepared the collection to be fully ready for integration into any sound file management system of your choice with industry-standard embedded Meta-Data.

Eternal Darkness sets a new benchmark, creating the most disturbing, creepy and downright terrifying collection of sounds available to date.

A Hybrid Thriller

Eternal Darkness contains a wide variety of terrifying and dark musical elements. Built from the ground up, this collection of hybrid instruments offers you all the necessary tools to perfect the art and workflow of creating truly spine-chilling horror scores. We made sure to include all the sound categories any composer or sound designer would need, such as a wealth of deep Impacts and Hits, ground-shaking Sub banks, length based Risers, rich and complex Drones and various tempo-based Rhythms, Tick-Tocks and Phrases to help inspire and add energy and drive into your next composition.

Hybrid Workflow

The advanced features included in the library are all easily accessible through the custom user-interface. Quickly adjust or automate the Attack, Release, Speed and Pitch Envelope of your chosen set of sounds, letting them perfectly fit within your track. From auditioning different categories to separating a sound to be chromatically stretched or further sequenced, the Hybrid Tools interface allows for endless customization. We have also included our latest Chaos effects module for even further polish and processing over your music.

Built-In Chaos FX

Eternal Darkness contains our very latest custom rack effects system. These Chaos Effects allow you to shape your sound in any way imaginable. Whether it’s creating movement and modulation within each sound using the dual Phaser and Flanger module, dialling in precise tonal changes with the inbuilt EQ, applying Bit Crusher & Distortion, or using the Dual Delays and multiple Reverbs to create a sense of character and space. We have also included a range of Impulse Responses which allow you to create Textural Convolution patterns. These are rhythmic phrases that overlay the existing sound and when coupled with the dual delay and spacious convolution reverb enables the shaping of your very own sound. Now in our latest version of the Chaos FX system, each effect can also be placed on any rack, enabling a genuinely modular signal flow.

Find The Right Sound

Finding the right sound for you just got easier. Eternal Darkness not only comes with a master patch but also comes with individual instrument patches for each “Song”. As well as the ease of browsing using our custom-built Hybrid interface, Eternal Darkness comes embedded with deep Meta-Data tagging, allowing you to directly search through the files using your favorite sound file application. This means key phrases such as Hit, Rise and even Beats Per Minute can be used to locate and identify suitable files, making finding the right sound out of the D.A.W easier than ever. At 48kHz / 24 Bit .wav, all the sounds within this library are drag and drop ready. Making production within or outside of the Kontakt format seamless and perfect for composers, sound designers and editors alike.
