Rust 4 is a collection of found sounds & creative percussion we recorded at an agricultural museum in Knightsen, California. We captured a 40-foot tall windmill in every way conceivable, pioneer-era farmhouse antiques and vintage household devices crafted from brass, copper, steel, tin, bronze and cast & wrought iron.

This is a standard open-format library for the full retail version of Kontakt. It can't be used in the free Kontakt Player or added to the Libraries rack. Click Here To Download the PDF User Manual

Rust 4 is the most extensive volume in our classic Rust series of metallic percussive and melodic instruments. For Relics, we explore the remnants of yesteryear at the East Contra Costa Historical Society’s agricultural museum in Knightsen, California. The museum preserves the last 150 years of Knightsen history - a small rural farming community nestled at the edge of the San Francisco Bay Delta where it opens into California’s Central Valley. The ECCHS staff generously let us sample a huge collection of their artifacts and exhibits in comprehensive detail.

We brought our custom studio-grade field recording rigs to roam the multi-acre museum grounds, equipped with large-diaphragm, mid-side pairs, and stereo contact microphone arrays to capture each sound in extreme detail and ridiculously pristine fidelity. We recorded ball, stick, felt and metal mallet percussion on dozens of distinct farm implements throughout the museum grounds, including heavy equipment, agricultural machines, metallic surfaces and objects of all shapes and sizes, from vintage horse-drawn plows, harvesters, combines, and motorized tractors to the complete physical interior and exterior of a vintage railroad caboose. We recorded a 40-foot tall windmill in every way conceivable, a whole collection of pioneer-era farmhouse antiques and vintage household devices crafted from brass, copper, steel, tin, bronze and cast & wrought iron.

We explored every nook and cranny for interesting tones and special effects, powerful booms, eerie screeches and moans, clanks, clatters, ratchets, gongs, musical rings and clangs in indoor and outdoor environments. We then curated and refined the content into a vast collection of playable instruments and effect banks, intuitively categorized into tunable percussion kits by object, style, tone and sonic character. All of the sounds are accessible through a single multi-layer sound designer interface and easy to play as full impact percussion ensembles, or soloed as melodic tuned percussion instruments. Rust 4 offers a vast variety of distinct sounds in every acoustic category, from delicate to brutal, and richly resonant to raw and gritty.


The Kontakt interface includes a suite of automation-ready sound-shaping controls to give you total creative flexibility. You have control over swell, attack, release, offset, vibrato, filter, pitch (coarse & fine), articulation switching, cross-fading and layering, and so much more.

This library comes with an adaptable LFO system, with selectable LFO shape, modulation target parameter, speed, intensity, tempo-syncing and fade-in time. You can also apply your choice of 12 lowpass, high-pass and FX filters, with assignable modulation targets such as velocity, modwheel, expression, after-touch, key position and step-sequencer table control. Our customizable arpeggiator offers a velocity table and control over arp direction, timing, swing, randomization and duration. We’ve included a key and scale lock system to constrain your notes to common scales and keys for easy melodic composition and live performance.

The interface is rounded-out by our modular FX rack panel, with 27 different DSP effect modules that you can assign in any of 8 available slots, in any order that you wish. You’ll find classic phaser, flanger, delay, distortion, amp and cab simulators, compressors, EQ, rotator and so much more. The Reverb effect includes our favorite convolution reverb impulse responses, including 99 different rooms, halls, chambers and outdoor environments, plus another 40 custom FX impulses to radically transform the sound and open up whole new worlds of musical possibility. We’ve added a great bank of FX rack chain factory presets to get you started!



This library is designed for the full retail version of Native Instruments Kontakt 6.2.2 or later. Kontakt is an industry-standard advanced virtual instrument software platform. You can view screenshots of this library's custom graphical user interface in the image gallery above. This library is packed with features to provide you a wide range of sound shaping parameter controls, each one totally automation-ready in your host environment or Kontakt's stand-alone mode. Learn more about Kontakt by Clicking Here.

This is a standard Kontakt open-format library, so the free Kontakt Player does not fully support it and can only run it in a limited "demo mode". However, the sample directories are unlocked so you can use them in other wav-compatible software, sampler and synth formats. The special Libraries tab doesn't support this open-format Kontakt library, but you can use the standard File browser tab and import this library into the Kontakt Quickload window for easy loading and navigation.
