Kontakt Instrument by Soundiron

Soundiron is known for their willingness to take sampling ever farther, to go to any lengths and explore every inch of the sonic world. Soundiron's never-ending quest is sampling literally every measurable sound in the universe that has musical potential. Perhaps Soundiron are compensating for a long-hidden fear that they won't measure up, or maybe it's just that Soundiron are willing to go miles beyond the rest to set a new metric for excellence. Time and time again, Soundiron have set new benchmarks in sampling and elevated the art to a whole new scale. Soundiron are willing to break all the rules in their quest. Soundiron's goal is always to reach imperial quality, no matter how tall the order. When Soundiron find that their catalogue has fallen short, rather than inch along, they put their foot down and fill in those gaps, because they'll never sell you short.

Long story short, Soundiron have all played with rulers and tape measures and noticed all of the satisfying sproings and wobbles they can produce. When you brace a ruler over the edge of a flat surface so that it can oscillate freely, it can produce a musical tone at a frequency in proportion to the distance it’s able to vibrate up and down. The longer the section of tine that can freely vibrate, the lower the note and the longer it can sustain. As you slide the ruler farther onto the surface and reduce the length of the freely-vibrating overhanging segment, the pitch increases and the duration of the note shortens. Tiny adjustments can result in large jumps, so you need to go millimeter-by-millimeter to produce a wide musical scale.

Because Soundiron are strange, they headed into the garage and grabbed their two best-sounding rulers and a couple of self-winding tape measures and then set out to capture one library to rule them all! Soundiron took no shortcuts! As the meters danced, Soundiron sampled every inch with millimetre precision, using finely calibrated microphones and pristine preamps to capture even the most minute details. Soundiron recorded 30 notes with a 6-inch ruler (15.24cm) and 38 notes on a 12-inch ruler (30.48cm), plus percussive taps, rattles and drops. Soundiron also recorded a wide variety of sound effects and percussive articulations with a 25-foot (3m) and 10-foot (7.62m) tape measures for a more modern take on the concept. Soundiron also tried to record a laser range-finder, but it turns out microphones aren't quite sensitive enough just yet. I guess the exception proves the rule: if it moves matter, it can make music.

Because Soundiron always bring you miles of value, they have included a collection of uniquely sound-designed ambient pads and tonal atmospheres created by manipulating the source recordings, along with plenty of custom FX presets to let you take the sounds even further. By any measure, The Ruler goes the distance!

The Ruler includes over 24 playable articulations, 20 custom FX presets, 20 sound-designed ambiences, 4825 stereo samples and a full gigabyte of content.


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. Soundiron also included 20 unique sound-designed custom FX presets to give you lots of creative options.

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. A customizable arpeggiator offers a velocity table and control over arp direction, timing, swing, randomization and duration. Soundiron 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 Soundiron's modular FX rack panel, with 18 different DSP effect modules that you can assign in any of 10 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 Soundiron's favourite 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. Soundiron added a great bank of FX rack chain factory presets to get you started!
