Rust 4 Black Friday deal: $29.50, 50% off, until Dec 6, 2026, for Soundiron's Kontakt library of found-sound percussion recorded at an agricultural museum in Knightsen, California.
The maker calls it the most extensive volume in the Rust series of metallic percussive and melodic instruments.
Rust 4 is a Kontakt instrument built from metal objects at the East Contra Costa Historical Society's museum. The Knightsen site preserves 150 years of local farming history.
Soundiron recorded with field rigs: large-diaphragm mics, mid-side pairs and stereo contact mic arrays. The goal was extreme detail on every hit.
Ball, stick, felt and metal mallets were used on dozens of farm implements around the grounds. The Rust 4 plugin's source material covers a lot of ground:
The team also hunted for booms, screeches, moans, clanks, clatters, ratchets, gongs and musical rings, indoors and out.
Soundiron sorted the result into tunable percussion kits by object, style, tone and sonic character. You can play them as full impact ensembles or solo a kit as a tuned melodic instrument.
Everything runs through one multi-layer sound designer panel. The sound-shaping controls are automation-ready and cover swell, attack, release, offset, vibrato, filter, coarse and fine pitch, articulation switching, cross-fading and layering.
The LFO system lets you pick the shape, target parameter, speed, intensity, tempo sync and fade-in time. Rust 4 includes 12 filters covering lowpass, high-pass and FX types, and you can steer them from several sources: how hard you play, the mod wheel, expression, channel pressure, where a note sits on the keyboard, or the step sequencer's tables.
The arpeggiator has a velocity table plus control over direction, timing, swing, randomization and duration. A key and scale lock keeps notes inside common scales and keys for melodic playing.
The FX rack holds 27 DSP modules across 8 slots, in any order. Phaser, flanger, delay, distortion, amp and cab simulators, compressors, EQ and a rotator are in there. The convolution reverb carries 99 rooms, halls, chambers and outdoor spaces, plus 40 custom FX impulses.
It needs the full version of Kontakt 6.2.2 or later. The free Kontakt Player leaves it stuck in demo mode.
On the system side, that means Windows 7 or higher, or Mac OSX 10.12 or higher. A dual-core CPU and 2 GB of RAM are listed, with a SATA or SSD drive recommended.
