Alarm Clock
by Christoph Thompson

Pasted Graphic 5

A vintage alarm clock that can be modified to play various rhythmic patterns. It is advisable to start with a blank slate and then start the modifications. Good for minimalist grooves, fun to tinker with.

Components on the circuit board can be added or removed by clicking on them. Potentiometers are for adjusting. Little adjustments can have a big effect. Have fun.


Drum Seq 0.5.2
by david els on

Pasted Graphic

808 type kick, hat and clave with individual sequencers and multiple outputs + more
Changes v0.5.2:
Added second kick - based on k-kick - same topology as first but with iterative ZDF Filters and different tone + gate and pitch sequencers - i use it for bass...
Added mixer section with volume, mute and solo - have removed trims from the individual instruments
Bug: noise when soloing instruments - its something with the new kick but i don't know what... a mars bar for anyone can fix it ;)

It's a 4 oscillator based synth with 32 voices of polyphony, related to Ambient music for the creation of textures. Please read the short manual first.


by Mike Clarke

Pasted Graphic 1

This ensemble is a near-perfect emulation of the extraordinary Commodore 64 sound chip. Included are all features of the original hardware:
* Three channels with Triangle, Square/PWM, Sawtooth, Noise and combined oscillators.
* Ring modulation and hard sync.
* The classic SID saturating filter that is incredibly important but missing on most emulations.
* LFOs and envelopes for pulse width, pitch, amplitude and filter cutoff.
* Step table at up to 50Hz for that genuine sound.

No attempt is made to create a better SID. No features are enhanced or improved. This is not the usual 'SID-like' or '8-bit style' synth. This is an attempt to recreate the real thing as closely as possible.


JP-4c Super Saw Emulation 1.6
by Alex Shore

Pasted Graphic 3

In 1996 Roland released the JP-8000, their first virtual analogue modeling synthesiser. The JP-8000 became very famous for one thing, the Super Saw. This unique sound helped define the trance music genre and is still commonly used in electronic dance music production today.

The JP-4c is a Reaktor patch designed to emulate the infamous Super Saw oscillator.

The JP-4c is built upon a combination of research conducted by myself and other individuals, with the patch being able to effectively emulate the original Super Saw's unique timbre. Detailed research and analysis of the Super Saw found that the oscillator exhibits some interesting characteristics giving it a particular sound.

Detune Curve
Perhaps the most important element is the detune curve. Whereas many synthesisers would commonly use a linear detune amount, the Super Saw was found to have a varying detune amount through the use of a curve. This curve allows the user a much finer control over the detune amount applied to the oscillator, allowing them to create very smooth sounds with a minimal amount of detune or seemingly harsh textures as the amount is increased. This parameter has been accurately implemented within the JP-4c to achieve the same detune characteristics as the original.

Oscillator Shape
The original Super Saw oscillator makes use of a high pass filter to cut the harmonics below the fundamental frequency. This filter helps give the Super Saw its characteristic bright sound by attenuating the low frequencies while also shaping the waveform, producing a smoothing effect seen at the peaks. This effect has been carefully recreated within the JP-4c to achieve the same rich tone as the original.

Along with these, additional features have also been reproduced and implemented including a built array of sound shaping controls and effects detailed below.


Super Saw Oscillator - Effective emulation of Roland's original layering of seven sawtooth waveforms

Second Oscillator - Four switchable waveform types (Triangle/Sine/Saw/Pulse)

Filter - Selectable Low Pass, Band Pass and High Pass with key follow

Modulation - 2x LFO, Filter Envelope and Pitch Envelope

Effects - Tone Control, Distortion, Reverb, Chorus, Delay and Portamento.

32 Factory Presets - 12 Leads, 8 Pads, 5 Plucks, 4 Basses and 2 Effects


This patch requires Native Instrument's Reaktor version 5.8 or later. Please refer to Reaktor's manual for further information.

WEST// 1.3
by Icaro Ferre

Pasted Graphic 4

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.

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.

"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
- The Revenge of Bucket Boy by Colin Brown

Original presets created by Ícaro Ferre.


- New Harmonic Oscillator module inspired by the Verbos Harmonic Oscillator
- New Quad Function Generator module.
- New BBD module based on "The Revenge of Bucket Boy" by Colin Brown
- New Control Voltage Processor module.
- The internal routing of the ensemble is much cleaner and easier to upgrade / modify.
- Added a subtle slew to ADSR 1 and 2 to make them sound more "organic".
- Fixed a bug that would prevent the Noise source selector to be properly saved in snapshots.
- Channel #4 of the VCA 1 is now selectable.

So, good news is that all the blank panels are now gone and WEST now features 4 new modules.
Bad news is that snapshots created with previous versions of WEST// won't work in this new version because of the new internal routing system, sorry once again about that.

I create 20 new snapshots which showcase most of the features available in WEST//.

- Fixed the clock source selector for the Sequencer
- Fixed some of the snapshots included in the Factory bank.
- WEST// now uses 2x oversampling by default (I recommend running it at 4x if you can). This means that WEST// will use more CPU but it'll sound a lot better.
- Added an Off option to some of the CV input selectors.

- New Spectral Processor module – this is a morphable fixed filter bank inspired by the Buchla 296e module. It's a bit more limited than the original module but it's still pretty cool.
The Spectral Processor has 3 different outputs (regular / all, odd and even). Regular / All output will output all the bands while odd (O) and even (E) will only output odd or even bands. Try processing the 2 bands in different ways and mixing them back together, it's pretty cool.
I also added individual VCAs for the Odd and Even outputs.

- New Wave-Folder module – wave-folder with selectable number of folding stages (2, 4, or 6).
- New 3-band Master EQ (Bass, Spectral Tilt, and Treble).
- New custom UI for the buttons inspired by the Buchla 200e series.
- Through-Zero FM now works properly.
- Added a toggle to switch Through-Zero FM on and off (available in B view).
- Added Key-Sync to LFO 1 and 2.
- LFO 1 and 2 were almost completely re-designed: the symmetry control in the factory LFO I used for the 1.0 version didn't work like I expected so I re-designed some parts (specially the triangle waveshaper). Theses changes also improved phase resets.
- Fixed the range of the ADSR 1 and 2 sliders .
- Added keyboard scaling for ADSR 2 (meaning the overall length of the envelope changes according to the note being played)
- Added MIDI Mod-Wheel (CC #1) and Aftertouch as modulation sources

This new version may not work well with existing presets / snapshots since the range of some of the parameters was changed / fixed.
The structure behind the instrument looks like a mess and I'm completely aware of that. My plan is to move everything to Send / Receive in the next update.
The interface is now a lot bigger and I'm not yet using 100% of it. I decided to leave some room so I can add more modules in future updates (or you can feel free to hack it up and add your own stuff). After all, many modular systems have blank panels ;)

I apologize for not adding many new snapshots to this update. I've been pretty busy and I didn't have time to make them. I'm hoping Paule Amca and other great guys here can help me out with that :)

Overall, I'm a lot happier with this new version. It sounds better, it is a LOT more flexible and the CPU usage is not as bad as I thought it'd be.
