The Ruler Black Friday deal puts Soundiron's sampled ruler and tape measure instrument for Kontakt at $9.50, 50% off, until Dec 6, 2026.
The Ruler is a Kontakt library built from two rulers and a couple of self-winding tape measures, recorded as pitched and percussive instruments.
It needs the full version of Kontakt 5.5 or later.
Brace a ruler over the edge of a flat surface and flick it. The overhanging section vibrates at a pitch tied to its length.
A longer overhang gives a lower note with a longer sustain. Slide the ruler farther onto the surface and the pitch rises while the note gets shorter.
Tiny moves change the pitch a lot, so Soundiron sampled it millimetre by millimetre to cover a full scale.
The sessions used finely calibrated microphones and pristine preamps.
Soundiron also added ambient pads and tonal atmospheres made by manipulating the source recordings.
The interface has automation-ready controls for swell, attack, release, offset, vibrato, filter, pitch (coarse and fine), articulation switching, cross-fading and layering.
An LFO lets you pick the shape, target parameter, speed, intensity, tempo sync and fade-in time. You also get 12 lowpass, high-pass and FX filters, and each can take modulation from velocity, modwheel, expression, after-touch, key position or step-sequencer table control.
The arpeggiator has a velocity table, with control over direction, timing, swing, randomization and duration. A key and scale lock keeps your notes inside common scales and keys.
The FX rack offers 18 DSP modules across 10 slots, in any order you like. The list includes phaser, flanger, delay, distortion, amp and cab simulators, compressors, EQ and rotator.
The convolution reverb carries 99 rooms, halls, chambers and outdoor spaces, plus 40 custom FX impulses. Factory FX rack chain presets are there as a starting point.
It runs on Windows 7 or higher and Mac OSX 10.9 or higher. A dual-core CPU and 2 GB of RAM are listed, and a SATA or SSD drive is recommended.
The free Kontakt Player will leave it stuck in demo mode, so the full version of Kontakt 5.5.0 or later is required.
Yes. The Ruler, Soundiron's Kontakt library, is 50% off during Black Friday, which brings it to $9.50. The deal ends Dec 6, 2026.
It has over 24 playable articulations, 20 custom FX presets, 20 sound-designed ambiences and 4,825 stereo samples, about 1.1 GB installed. Samples are 24-bit / 48 kHz uncompressed WAV, loaded through one master NKI bank in open Kontakt format.
No. The Ruler needs the full version of Kontakt 5.5.0 or later. Loaded in the free Kontakt Player, the instrument stays stuck in demo mode. It runs on Windows 7 or higher and Mac OSX 10.9 or higher.
Soundiron recorded 30 notes from a 6-inch ruler and 38 notes from a 12-inch ruler, plus taps, rattles and drops. Two tape measures, 25-foot and 10-foot, added sound effects and percussive articulations.
