Integration of some of Salamanderanagram's designs. Watching his YouTube tutorials at has been a great study aid.

Hover over a section's frame label for a list of what the dials do.
The sequencer has 8 patterns and is hardwired to the amplitudes of each oscillator. The modulation depth can be set per oscillator with the "Variable threshold" parameter.


DR-OP for Modular-X
by Michael Stocker

Pasted Graphic 5

DR-OP is a (semi-)modular Synth designed with the Modular-X framework by Herwig Krass.

This release has a new Module, the DR-OP and an update to the Seq-6 Module.

The DR-OP (dreifach Operator = tripple operator, stupid acronym) tries to be a compact and simple 3-operator FM module with internal envelopes and some other toys. It was inspired by a thread about "More 'Hands-on' FM Synthesis" one a big blue synth/gear forum. I´m not 100% happy with the result, but it can create some nice and interesting sounds reasonably easy, so I think it is interesting enough to release it.

The Seq-6 is a simple 6-step CV sequencer, that got updated with additional gate sequencing.

p.s.: I know I should build less crowded modules with a clean internal structure. It did not really work in this case... I will try to do better on future releases, but this one was half finished for quite some time, so I was still stuck in the crowded interface mindset when I started...


Drifter 1.1
by Bradley Hale

Pasted Graphic 7

A simple two oscillator synth designed to create thick and lush pads. The "drift" control offers a slow rate LFO to add a bit of an analog warble perfect for giving depth to a pad. Dial in the reverb to float off into a bed of chordal bliss.

Harmonic series generator

1. Recoded the amplitude LFO in core to get 64-bit frequency values that synced correctly. (They got out of sync in v1.)
2. Added cycle bar to show where harmonicSeries is in the main cycle.
3. Made panning opposite for odd/even harmonics (odd goes left right left right, even goes right left right left) to balance the stereo field.

A one-trick pony, but a pretty good trick: harmonicSeries generates a set of up to 64 harmonics, each of which performs its own cycle (amplitude, panning) within the overarching cycle of the fundamental.

Thus the form of the cycles (within cycle (within cycles)) mirrors the form of the harmonic series itself.

good for noises and drones.
Does not sound very modern.

Pasted Graphic 9

for generating noises, sound textures or weird rhythmic stuff.
Haben Sie bitte Spass.
Reverb effect based on Cloud nr. 9 by Brian Lake. much thanks.


modal 32.1 v.1.2
by gentleclockdivider

Pasted Graphic 3

Well basicaly it's the modul bank tutorial ..+some extras,..mouse sweeping for instant editing of the first 32 partials ...tuning , amplitude and decay ..
Fixed and user defined harmonic series
Added the metaver from stephan schmidt ensemble ca-osc' ( try it , it's wonderfull )
Update ..same knobs as in clonetonic ..yuy


Slicer 0.52
by david elson

Pasted Graphic 2

Grainy Slicer

Update 0.5.2
Replaced step sequencer with Peter Dines' Roux
this allows current step marker and is less complicated
Different sample map (both sample maps are VERY LoFi - will add a more modern dynamic map and snapshots to the UL at a later date)
Traditional Reaktor UI - old skool ;)
Second - modulation - sequencer and destinations
More snapshots

there is a short video here:


Tyrion Modular
by Christian Huygen

Pasted Graphic 8

Meet Tyrion. He’s small, handsome, talented, and deadly. You could spend hours in his company learning new tricks, and finding out what can go where.

QUICK START GUIDE: In a modular synthesizer, you can connect anything to anything. Go from dark to light: left click an output (dark gray) and then an input (light blue) to create a cable connection. To delete a cable, click on the red input and it will disappear. All connections must be made explicitly: if there's no cable, there's no connection. Control the color of future cables with the CTRL module in the lower right corner. You can also change the transparency of all cables there. One output can control many inputs, but each input can only have one incoming connection.

Please see my other Modular-X ensembles (such as Allegheny Modular) for additional notes and info. The lion's share of the work here was done by Herw and others. Much gratitude to them.

Sometimes bigger is better. And sometimes small is even better than that.

WEST// is a west-coast style monophonic synthesizer.
Since there aren’t too many of this kind of synths available for Reaktor I decided to try to create something. WEST// was inspired by the sounds of the Buchla modules and the semi-modular workflow from the ARP 2600 synthesizer.
It contains a Complex Oscillator (FM based dual-oscillator), a filter similar to a low-pass gate, 2 ADSRs, 1 Multi-Stage envelope, Noise generator, 3 VCAs, 2 mixers, 1 sequencer, 2 random modules inspired by the Source of Uncertainty, 2 regular LFOs, 1 Self-Influenced Random module, a frequency shifter and a Wave Multiplier.

The workflow on it is a bit particular so here are a few tips to get started:
- The VCA 1 is linked to the Master output and it’s always controlled by the ADSR 1.
- The sliders available on the Complex Oscillator behave as offsets when there’s no Modulation selected. Once you select a modulation source, the sliders turn into attenuators for the incoming modulation signals.
- Shape 1 and 2 are a bipolar slider

I’ve also created some custom sliders with a particular color scheme (inspired by the Buchla Easel):
Gray Sliders - Control Voltage
Blue Sliders - Audio Signals
Yellow Sliders - Time-based controls
Green Sliders - Audio Modifiers
Orange Sliders - Sequencer

The Self-Influenced Random (SIR) module is a special S&H circuity that can take the CV output of the S&H to control the frequency of the clock oscillator used to trigger the S&H. The SIR CV output is available in almost all of the CV inputs spread throughout WEST// however I've also added gate outputs which can be used to trigger the 3 envelopes.

There are still many other feature I wanna add to WEST// however this is a pretty solid 1.0 version.

"If I have seen further than others, it is by standing upon the shoulders of giants."

WEST// uses a couple of previously programmed parts:
- Wave Multiplier by Sandy Small and Kim Boestrom
- Frequency Shifter by Sandy Small, Sean Costello, and Jesse Voccia.
- Spring Reverb by Boscomac
- Source of Uncertainty by
- Low Pass Gate by arachnaut
