Best of Reaktor User Library july 2.011


By Benjamin Suthers

This is a pretty good model of how the gain reduction is created in the SSL 4000 series bus compressor.

Time constants, thresholds, and ratios behave in a similar manner.

more updates - this update just performs a little math in the gain reduction circuit so that it doesn't...well anyway- maybe this is the more of the sound that you were looking for...maybe it's not.

redid the bypass as well.



AutoDrummer v1.0
By Jim Hurley

March to the beat of a different drummer
(This is too big for the U/L - download to get instructions.)

AutoDrummer is a self-generative Reaktor toy featuring 3 different MIDI automata: Automato, Spiral and Life. The image on the User Library page shows the different panelsets.

Automato by salamanderanagram (Donald Phillips) provides the MIDI notes for the rest of the ensemble; it can be used by itself, or programmed in turn by Spiral or Life which were both made by Lazyfish (Alexander Potekhin).

The sound generation section consists of an 8 part sample-based Drum machine - 'Gonzzo Classic' from the Reaktor 3 Library by Uwe G. Hoenig followed by a 'Stereo Delay' made by Thomas Medes, followed by the fabulous Laserbrew 1.3 by Tim Schwerdtfeger, followed by the granular Shred 1.0 by Christopher Lenz.


Bass for Brains - TB303 v1.0
By Jesse Allen
A TB303 like seq/synth
I pulled various reaktor patches together to create a very fun version of the Roland TB303. The unit will play in sync with a sequencer. Effects include an acid delay and distortion/overdrive.

I take no credit for making each element just bringing these great things together and some presets.


Electrode Suite v1.0
By Bradley Gray

Four different flavours of groovebox goodness.. + mixer + FX
What else to say?

I've been working on this heavily for the past few months. Started out as digitalisation of Electribes. I added a few things to each that I'd like, took out other things I didn't need at the time. It became something a little more. Then I created an entirely new one from scratch.
Samples where used are taken from freesound and a few other sources.

Four different grooveboxes:
-Electrode SE is a rhythm sampler. 8 parts with FM and (resonant!) filter, up to 16 steps, built in compressor and drive.
-Electrode RE is an 8 part, 16 step analog rhythm machine. Four different waveforms (inc noise), pitch EG, gate time based EG, and resonant filter. Also includes built in compression and drive, plus delay and bitcrusher!
-Electrode AE is more of a 303 at heart than a properly versatile synth like its hardware inspiration. It has four continuously variable waveforms, suboscillator, uniquely modelled resonant filter with FM feedback, A/D R EG, LFO, and built in compression and drive. Currently the AE is the only module with a 64 step sequencer.
-Electrode LE is a completely new design. It allows you to sequence and pitch shift loops. One sequencer row to control loop retrigger, one for A/B loop swapping, and one to control gate on/off. Also features built in EQ, and the familiar compression & drive.

NOTE: The compressor control on each module is actually a threshold.
Reduce it to bring in compression. The comp itself is based on the Reaktor built in compressor, with all the parameters already finetuned or scaled to the control to give it a certain response character.

NOTE: Use the ensemble master snapshot control (click in blank space or use the dropdown at the top of the screen) to try out the many different pre-programmed patterns I've put in to try out.

Also included .ins versions for dropping into your own ensembles.



FlexStation v1.0
By Bradley Gray

Multi modeled workstation Synth
Again, something unfinished that I've decided to abandon 'as is', for a more efficient project.

The 'FlexFX' section I also used a cut down version of in my formant-fm 'Formation 1' synth.

It has 16 (I think) graincloud based multisample banks, but once you pass that you get oscillator models including organ, analog, sync, and an FM structure (including filter), PWM, string machine, detune, etc.

Again, more than a little CPU hungry, but the voice count is quite high. I originally intended this to be my go-to synth for a hardware system I was designing. Feel free to lower the voices, although I think the FlexFX uses up a lot of resources.
Also, only the rotary effect in the last FX module is finished. The others have a bug, although it is passable and used in some presets.

Other unique features include an EQ-based filter section, per voice drive, and plenty of modulation routings.

The design ethos and layout of this comes from my experience with the K*rg Triton series workstations.
Originally I really just wanted to make a triton emulation with an organ oscillator 'waveform', but then I wanted to implement some other features I'd thought of too.


Green Monster v1.0
By Joshua Stemper

FM Synth with sequencers to control modualtion
I began studying reaktor a couple months ago and decided it was time to share what I've learned. This is a pretty simple but nasty sounding FM synth with 3 carriers and 3 modulators with tables to control the modulators. You need to hit play for the tables to work.


OMega v1.4
By Jim Hurley

A powerful, flexible, easily changeable synthesizer.
Part of the Reaktor Builders Macros series.

OMega is a flexible synthesizer with standardized, easily changeable parts including:
10 oscillators;
20 filters in 2 banks;
20 effects in 2 banks;
30 inserts in 3 banks; and a
3 x 8 x 8 mod matrix.

There are multiple background images in panels allowing users to customize the color scheme if they wish. All the major components may be moved around to fit your display and workflow.

OMega offers many routing possibilities:
the oscillators may be cross-fed to two filters and can modulate each other;
the filters and effects may be in series or parallel;
inserts may be placed in pre- or post-processing positions;
feedback loop processing is available with a choice of three paths; and
handy indicators show ALL active components.

The oscillator-filter path is fully stereo and multi-voiced with many types of spreading effects (pitched, delayed, FM/AM modulated, etc.) to generate richly chorused sounds.

Documentation included (see B View) - OMega Description (PDF), architectural diagram, filter configurations, effect configurations. Test gear included - phase correlator, FFT analyzer; 4 chan scope; test tones. Utilities built-in: overload indicators, tremolo generator; sub-audio filter; transparent limiter.

Designed for a 1920x1080 HD display and a very fast CPU.


ThreeO v1.1
By John Bleech

3-oSC modification
3-oSC is an old, but good, synthesizer from the Reaktor Legacy Library.

Modifications include: frequency modulation, pitch modulation, oscillator sync, volume mute for the oscillators, amp velocity, custom delay, new snapshots, GUI. Knobs are by Jonathan Style.

There are two banks of snapshots: the original bank from 3-oSC and a new bank of altered snaps. I retained the entire original synth - just added more features - and so the original snaps sound the same on both synths.

v1.1: A mod. wheel can be used to crossfade between filtered and unfiltered sound.
