doubbleringmodulator v1.0

By Urs Baumgartner

double ringmodulator with 2 lfos and a filter at the Output

EarSafe v1.0

By Florian Schwehn

alternative Bit and Sample Crusher

This is a small collection of more or less classical destructive tools to mash up your sound featuring:

- Buzzer & Bit Crusher
- Samplerate Reducer whith Formant and Harshness control
- Saturation
- some Auto Degain and Damping functions to save your ears!

So just another Lo-Fi tool? I tried to make these old ideas easier to handle so that you can allways achieve the right loudness and sharpness.

A speacial feature is the sample rate reducer with integrated formant and harshness control. Never heard of something like that? - so check it out - I really like it.

Freeeze v1.3
By Patrick de Rham

trigger/freeze granular effect

Freezes one chord/note and makes it infinite... until the next one. Simple to use: the attack triggers the note. Some controls on the texture. Made with a graincloud delay effect. Works well with my guitar (not tested with distortion: just finished)

1.3 slightly better look

Multi Breakpoint Shaper v1.1
By Florian Schwehn

Multi Breakpoint Shaper


- up to 16 completely free moveable breakpoints
- three different interpolation modes
- an auto level function

Update Vs.1.1:

- I'm sorry, Vs.1.0 only put out a mono signal, now it's fixed! (remember to switch to 1 voice to run instrument in mono mode)

- I increased efficiency a little bit

QSL v1.0
By gabriel mulzer


4 band soft sat compression

regular mortgage v1.0
By gabriel mulzer

Efficient reverb / room simulation / externalizer

Efficient physical room simulation with binaural reflexions,
HRTF for the direct sound, and 'BaBox' FDN late reverberation

Mono in - 3D out

Loop and Beat Machines

buffer::graf v1.0
By daniel battaglia

granular livesampler with a small footprint

this is an updated version of a live-sampler i posted to the forum recently. it is small and easy to use, yet is quite versatile. instructions are printed on the panel itself.

i don't know if graf is even a word. enjoy!

loGjammer3.2 v1.1
By Andrew Rice

No Random. Snapshot Tables. True Continuous Loop Seqs.


-the last version (3.14159) was sending too many resets to the beatloop. i fixed this. no unwanted glitching now.

-A "BREAK" is no longer destructive to the programmed sequence. Good for adding "rolls" or improvised beat re-ordering to your favorite loops.

-No more "randomizing" patterns. Now you can save table data per snapshot.

-The Qwerty (or midi keyboard) is used for note-pitched break triggering.

-Pitch now has GLIDE!

-The waveform window is an XY controller used for selecting "slices" of the loop.

-Clicking with the left mouse button triggers a C60 note-on, the same as pressing "Q" on your Qwerty, or middle C on your midi keyboard.

-For intended results samples must be 1 bar of 4/4.

sort of the rings R5 version v2.0
By programchild

automatic soundscape generator:

this is the r5 updated sort of the rings instrument.
just digged it out and had some fun with it.
-redone soundsection with sampler and sine oscillators
-enhanced event handling
-more controls


further update:

now has "autopilot" for slow pitch range variations so the music will be more interesting over the time.
just check it out, HIT PLAY and let it run...

SQp+ v1.0
By Christian Björklund

SQp mod, improvements and live features

So, here's what I have done to SQp:

- Alternative sequencer clock, working as a typical step sequencer with playback modes like backwards, ping-pong and random.
- Velocity edit clearer, and can handle single notes in chords.
- Step recording
- Shuffle, transpose, offset, note lenght setting
- Live functions like time quantized offset and "repeater" some smaller fixes and improvements.


The Fly v2.0

eMix v1.0

By Robin Parmar

Studio mixer with cross-fader.

eMix is a studio mixer with 4 mono channels, 4 stereo channels and 4 sends. EQ, solo and mute are available on all strips as appropriate.

Solo is implemented so that the entire channel strip is still active. In other words, solo is not a separate bus, but simply tells that channel to be on, along with any other selected solo channels (but without any that are not soloed).

The sends are stereo on the stereo channels. The knobs control 1/2 and 3/4 respectively, with on buttons for each pair. On the mono channels there is still only one knob per pair, but each of the four sends can be selected individually. This given a greater degree of control than is usual.

Any of the stereo pairs can be assigned to either side of a cross-fader. When this is on, the master is fed by the output of this cross-fader. Otherwise the master is fed from the normal summed stereo bus. Note that in either case the meters are active, so you have some idea of the signal before you punch in the cross-fader.

The master section has a fader both pre- and post- the master compressor. This is a 2-knee design, with a low and high threshold, each with its own ratio. As is usual, there is an attack and release control, calibrated in milliseconds. The vertical display show you visually where the thresholds are set.

This instrument consumes about 9% of the CPU on my computer. For reference, this is about half of what Carbon 2 uses.


Compressor is from the Reaktor library, by Erik Wiegand (c) 2003 Native Instruments. Some of the mixer functions started out as the Studio Mixer macro. The cross-fader was extracted from Reaktor DJ by Keisuke Sudo. Other parts may be derived from other places, but who can keep track, y'know?

This instrument (c) 2006 Robin Parmar. Use it as you will, tear it apart, improve it. But don't sell it and please reserve this note.


Derelayer v1.4

By James Clark

An experiment with pitch synchronous delays

An experiment in harmonic manipulation using pitch synchronous regenerative delay lines applied to oscillator waveforms. Good for making shimmery pads and off-centre leads.

Note: This is a CPU hog (30% on my machine), but well worth the extra cycles in my mind.

(I shamelessly stole the mod wheel image and delay and chorus modules from Stephan V.'s great Tritium synth. Thanks Mr. V! And thanks to Bernd Keil for the knob images)

minithin v2.2

By Andrew Rice

Super Small Basic Subtractive with Fingered Glide

I wanted a basic synth that took up very little screen room and little cpu but was also useful.

Used "Core Selector 1" By Colin-Patrick Charles for the multi-osc & multi-filter selection. Thank you Colin.

Used a module found in Oki Computer 2 "Pre-Legato" which makes the Fingered-Glide possible. Thanks to Tim Lamb and James Walker-Hall.

All audio is Core.

Also thanks to Chet Singer for showing some interest and uploading another Fingered-Portamento module.

I know this is not anything ground-breaking but its exactly what I needed. Hope someone finds it useful.

minithin2_2 w_pitch_delay_v1
By Don Dailey

Same as above synth but with pitch delay module added

minithin Remix v2.0
By Urs Baumgartner

Remix of Andrew Rices Minithin 2.2

I added some modules to this well working synth.

Thanx to Andrew Rice, Colin-Patrick Charles, Tim Lamb, James Walker-Hall, Chet Singer and Don Dailey for your work in this synth.

For the update i just set to midi channel to 1.

monopoly v1.0

By Andrew Rice

an intermediate-level subtractive synthesizer:

2 Osc
-Pitch and Symmetry LFO

Tandem Filter
-1 for each Osc.
-Both Filters share the Filter Envelope.

2 LFO's

-Oscillating or Sync to Clock *
-Both LFO's can be easily mapped to ALL available parameters with the "All On / Off" buttons.

4 Randomizers for randomizing fewer parameters at a time. **

* must run transport if LFO's are in Sync mode.

** click the XY scope to randomize all 4 randomizers at once. This is still less destructive than using the global snap random because only certain parameters per module are mapped to the LFO's.

FLIP to B mode for a giant scope.

Para Wahn2 v3.0
By Dieter Zobel

einfacher synth, einfacher sequenzer

Piano PP v1.0
By gabriel mulzer

augmented piano sample player

a by-product of a full physical model I am working in from time to time

you can load your own samples, but probably will have to change some settings and stuff in this case, it's using just a plain single layer mono sample

Features :

dynaVeloX Filtering
softHold Desimulator
phySonance Model
HiBoard-Response Architecture
schmartDampf Emulation
ARS adaptive R-strike! Logic
TTT tensedTemperTunings
virtAmbience Augmentation
OnScreen Output Volume Control Knob

but probably the best thing is : you can switch some of those options off
I've included some tweaking parameters in B view, some other parameters are hidden in the structure and can only be changed there

credits :

sample found on the net ( included for demonstration purpose only ..)
some tunings stolen from E.Meyer ( I think) , some modeling based loosely on papers by Balasz Bank, Davide Rocchesso, Gabriel Weinreich
the demo files ( if included ) were created from MIDI files by Nicolas Fogwall and Tanja Tysmans I believe -

Pulsation v2.0
By Jonathan Style

This is a synth based on the Waldorf Pulse.

This is my first post on the Reaktor User Lib. This simple 3 Oscillator Mono synth is based on the Waldorf Pulse, it is not an emulation. I Removed the "Band-limited oscillators in Core v1.6" created by Robin Davies and used Reakotr's normal Oscillators, it has lowered the CPU considerably. The Finger Portamento is the work of Chet Singer. 17 presets are included; however, I am not the best creator of presets. Any suggestions that can help me to give it the character of the Actual Waldorf Pulse would be appreciated.


3 Oscillators (Pulse, Sawtooth, Triangle, X-Mod)

4-Pole Lowpass Filter

4 Modulation Matrix

SnareDrum v1.1
By thomas escure

Synthetic snare drum

I love electronic drum sounds!
Here I've tried to push the "808 sd" concept a little further.
I wasn't sure wether to upload it or not in the UL since it's a very simple unit, but eventually I did because :
- this work is somehow the result of good advices I've had from other Reaktor builders on the forum;
- I love the "sharing" habit that most builders seem to have;
- maybe it will be helpful for someone looking for a snare drum sound.

Please tell me if there are things you find "strange" or awkward in the way I built it, or if you think it could be improved(I'm sure it can be!)and how, since it's my first upload in the UL.

Edit :
I forgot to say that you have to hit the "C1" key on your keyboard to hear it.

The Modder v1.0
By Florian Schwehn


The result of damaging a quad oscillator.

You can modify it's balance by shooting at its cosine with noise, crackle (and little black holes) in the "Modding" section and hinder it from restoring its balance by using the "Normalizing Filter".

V-Waves 5.0 v1.0
By Stephan V.

"Digital" Synthesizer

Some kind of digital synthesizer with 66 original access virus waveforms.

- one digital oscillator with 66 waveforms in 4 variations, adjustable width, spectral shift, quantization and a triangle suboscillator
- 2 and 4 pole lowpass filter
- 3 adsr-envelopes (amp, filter and modulation)
- one lfo
- velocity matrix
- pitch bend and assignable modwheel
- a modulated delay effect
- external effect loop

the overall concept of this synth is quite simple. it's easy and intuitive to use and has a relatively wide spectrum of sounds but with strict limitations demonstrated in the 32 snapshots. i'm not a friend of huge ensembles that make everything possible. too many possibilities poison creativity
