Best of Reaktor User Library february 2.014


by Brian Lake


The reverb algorithm is basically just a stripped down version of Spacemaster with a few added bells and whistles, such as "Volume", which has a simple Attack & Release envelope hooked up to controller 64 (sustain pedal), allowing for volume swells without the need for a volume pedal.

I've been thinking about tinkering with the "Chorus" module (in future releases) and implementing an "Embed" feature that will switch from chorusing the incoming audio and "embed" the modulation within the diffusor chain, which (I imagine) would result in a "chorus-verb" effect similar to the reverb in Errorsmith's "Razor" ensemble, which I have a huge crush on :)

The "Tremelo" module has a nifty little "After" button that switches from modulating the overall amplitude of the incoming audio and instead modulates the reverb tail...a sound very similar to the opening guitar riff from "How Soon Is Now" by The Smiths. I prefer this setup as opposed to the more common serial routing situation.

The "Freeze" module has a button labeled "Infinite" that bypasses the "Filter Cut" module, which results in huge decay times that go on for several minutes. I would rather have used a "Grain Cloud" module like the one used in Guenther Fleischmann's "Ultimate Reverb" ensemble, but I've yet to understand how it works, so I took a more practical approach.

What can I say? I'm a stickler for keeping my ensembles as original as possible and I just don't feel comfortable squeezing other people's stuff into my own work. I'm just weird like that :)

Even though I started with a gutted Spacemaster algorithm, I feel comfortable taking credit for most of what you see here. I even did some work in a completely separate ensemble where I did a fair amount of experimentation phase shifting sine waves in order to perfect the "Modulation" section, wherein some metallic artifacts were bumping up against each other as a result of a global phase value being fed into each LFO module.

I tried to keep the front panel as intuitive as possible, routing the "ER/LR" knob to several locations in order to kill the feedback while listening in on the early reflection times since the entire feedback loop is running through a global filter, which is more CPU economic. I managed to keep it under 12% with everything switched on, but the reverb by itself takes up a little over 8%.

Anyway, I could go on for hours explaining every little detail, but I have a life to live and so do you...

A recreation of the EQUO effect

A few things are missing like:
1. panning
2. oversampling
3. line and curve drawing modes

But everything else works good.

A few fixes in v1.1

Lock modes has been added to the bandpass filters in v1.2


Linear phase crossover
by Jan Brähler


two small ensembles:
one does a single finite impulse response bandsplit,
the other splits the spectrum to voices where each voice carries a band.

the used filter is a gaussian lowpass approximation without using a fft.


Live Master Multi FX
by michael o'hagan


A 4 channel live multi FX unit (beatlookup mod)

This is a live audio FX rack with 4 selectable inputs,
it does slicing, filters, distortion, grains, pitch shifting and more.

It was made from CLists (Chris List) beat lookup, and has a lot of new features added to it.

Phobos Variations.
by Lars Bo Hermansen

30 Snapshots variations for an easy to use PAD maker synth. Basic but virus area too.
30 Snapshots variations for an easy to use PAD maker synth.
Also caple of producing pad's in the Virus area.

Rather basic.

Thanks to John Saunders for the synth.
Try it out.I think it deserve it. It's a good little easy to go to ensemble for pads.
Here is a link to the synth made in 2011:

Lars Hein 23
by Mary Jean-Philippe


Feedback Synth/Fx
It is the synthesizer which does not use oscillators as source but a feedback of delay,
it is a kind of Larsen!!!

The sound generated by this module goes in a filter, in a Phaser / Flanger then a reverb.

The frequency of the delay, the phaser / flanger,the filter (new in 2.1) and FM filter (new in 2.3),
can be modulated by the keyboard.

Lars Hein is at the same time a Synthesizer and can be also used as effect.

I thank particularly Lars Bo Hermansen and Bernd Keil for their interest.
their Snapshots is included in this version :)


Mercury 2.0
by Stephan Becker


Polyphonic Synthesizer
Classic analog style synthesizer somewhere between a prophet 5 and an access virus.
Nothing special but a solid allrounder.
3 Oscillators (2 main, 1 sub) + noise generator
2 filters, 24dB low- and highpass with serial and parallel routing options
multiple saturation stages
poly-mod section
64 snaps
full midi implementation, cc-numbers are shown in hints
2 panel layouts, panel A with snapshot selector,
some basic controls and an on-screen-keyboard, panel B with detailled controls


Jade Juicer

An attempt to keep only synth features that make for interesting sounds
and a UI that is compact with no useless knobs. 10 presets so far, will update with more.

Synesthesia.2 (Hybrid Granular FM Sampler/Synth)
by Kyle Altenderfer


New link for download and description of instrument:

Synesthesia has been a labor of love for quite sometime. There was really no one synth that employed most of the functionality I like to use. There are a few that come close but, most of the time I’m bouncing things to and from different instruments. If I want a sampler that had FM ability, I have to use program A. Then I want to granulate it, I have to use program B and so on. Not that I won’t still use these programs, Synesthesia just makes it easier to piece things together. The Synth is mostly geared towards making very ominous, detailed, and layered type sounds. Included are quite a few samples of my own that even make this sound like an “additive” type synth but, technically I won’t say it’s additive. You should have plenty of options with these samples but, the real power becomes apparent when you import your own samples into Synesthesia. Coupling that with Reaktor’s morph and randomize abilities… This turns into a very good “happy accident” machine. At first sight Synesthesia may seem a little intimidating but, there is also an easy to read one page manual included and every knob inside has detailed tooltip information. Just hover over a knob and see what it does.

Functionality of Synesthesia

4 oscillators with selectable types: Sin, Triangle, Pulse, Saw, Noise and Sampler. Each oscillator has an independent Dly-ADBDSR amp envelope as well.

All oscillators accept FM input except Noise. The Noise oscillator can still -send- FM. This is used and visualized easily with the on screen FM matrix. Meaning, no menu diving to fine tune the FM controls for everything.

Granulation abilities are possible with the included Grain Cloud effect.

When the sampler module is selected, each oscillator has 34 preloaded samples. The samples range from simple waves, to complex additive like soundscapes.

13 filter types: 2 pole highpass, 2 pole bandpass, 2 pole lowpass, 4 pole bandpass, 4 pole bandlimit, 4 pole lowpass, 1 – 4 pole ladder (modeled after the moog’s lovely filter sound), Pro-52 (modeled after the Sequential Circuits’ Prophet-5 filters and used in Native Instruments Pro-52 Synth), 2 pole notch, and 1 pole allpass. Filters operate in both series and parallel mode as well as having a fade option between the outputs of each.

12 modulators: 4 Dly-ADBDSR envelopes, 4 LFOs with an array of settings, and 4 sequencers.
Modulation Matrix with 10 slots, 12 Mod From selections, and 23 Mod to destinations. This gives the synth an array of modulation possibilities.

5 built in effect units: Grain Cloud Delay, Chorus, Reverb, Compression, and Stereo Imaging. Each of these effect units have a fair amount of tweak-able controls, many of which are modulatable from the Mod Matrix.

And to polish it off, a very ascetically pleasing interface to work with. Also, most controls are directly in front of you.

33 presets/snapshots included to get you going.

**Note: there is still one bug in this release, I’ll do my best to fix it in an update. On RARE occasion a NaN error pops up in the Delay unit, causing audio to completely drop out. To fix the audio drop out, simply use the power button in the upper right corner to turn Reaktor off and then on. This resets everything and it should be fine from then on after.

**UPDATE** 02-11-14

Version 2 is now available but, currently working out version 3; which is a massive overhaul with many new features.

Teaser list: over 100 custom wavetable oscillators, granular oscillator mode, new filters, new effects, Multi Breakpoint Envelopes, more modulations destinations, modulation modifiers and more. STAY TUNED !!!
