About Randomisers Series – Abstrung by Audiofier

RANDOMISERS SERIES is a themed sample library collection for modern producers and composers.

It includes recordings of real, modeled, synthesized and designed instruments, resulting in an original palette of inspiring sounds for creators of electronic and organic music.

The 1.2 Engine features two multisample, 3 Round Robins Sound Sources,  a Twin Step Sequencer, an Arpeggiator (and yes, they work in Tandem!), Step Effects, Trails Layer, a Sequence Midi Drag & Drop function, a Crystal Generator and the trademark intelligent Randomisation function which allows to generate fresh and useful sounds every time.

On-the-Fly Reverseable sounds

Reverse sounds on the fly. Adjust the sample start of reversed sounds with the mod wheel.

Mutate Sounds

Mutate your sound layers with 180+ effects included in each of the two new Convolvers.

3 Play modes

Play both sound sources at once (Single map Mode), one per key zone (Dual Map Mode) or randomly (Random Map Mode), creating interesting changing textures.

Randomisation Power

Audiofier’s new “intelligent” Randomiser feature makes it incredibly easy to create new sounds quickly and makes presets redundant. Sounds can be randomised fully, or within one or a blend of two of the 5 available sound categories.

It also possible to recall past randomisations and go back and forth in the randomisation history, also recalling past randomisation on the fly.

Fully customisable

Create patches from scratch, with multiple ways of choosing sound sources, including a categorised Sound Browser, which works hand in hand with the randomisation engine to create sounds which are “just right”.

Crystals Generator

Generate special delay lines that can be pitched and harmonised in triads, fifths, suspended or  random for a total inspiring sound creation! Filter, and blur the Crystals with the Cloud filter. Grains can be more or less pronunced to one’s taste. Finish them up with distortion, phaser and an additional delay.

Split personality

Play one or both sound sources per zone with one or two sequencers running. Play pads and sequences at the same time or in split mode. Assign Crystals  below or above the user defineable split point. And more…

Step  & MasterEffects

Add movement and filtering to pads and sequences with four step sequenceable effects: Filter Cut off and Resonance, Distortion & Formant Filter

Add finishing touches to your sound with Convolution Reverb, two delays, Chorus, Shine, and Lo-Fi effects.

Twin Step Sequencer.

Use two simultaneous step sequencers with 8 memory slots, changing sequence on the fly via keyswitch.  Record your sequences by playing, not by drawing.

Spice up your Sequences

Generate random  sequences and “improvise” temporary sequences at the tip of a “keyswitch”, to spice up some stale repetitive phrases.

Export your sequences as Midi

The  Randomisers Series 1.2  includes a System page which gives acces to the Midi Drag & Drop feature. Generate sequences performances, export them on to you DAW and edit them or assign third parties sounds to them.

Arpeggiator fun

Arpeggiate short sounds or trigger sequences with the arpeggiator (yes you can!). Play sequencers and arpeggiator in serial or parallel with 2 different sounds.

“Randomiser Series (Abstrung, Aerkord, Vesper) is a carefully selected combination of three Kontakt instruments for modern producers and composers. Features like the Randomiser feature makes it incredibly easy to create new sounds quickly and the now available Kontakt snapshots. You can dive into this library or just create great tracks. The new engine is adjustable to support both approaches.”

Strong Mocha Review


“With their latest release, Audiofier offers an affordable entry point to the interesting and vast world of unique hybrid sounds. For anyone delving into the world of hybrid scoring, Abstrung is a no-brainer.”
