Doepfer A-150-8 Octal Manual/Voltage Controlled Programmable Switches Announced

Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.)
Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:

Module A-150-8 contains eight manually/voltage controlled switches. 
Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2). 
The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. 

A-150-8 Octal VC Switch prototype
Two LEDs show which in / output is active (ie. which is connected to the common out / input). 
In addition the LEDs are used for the programming of the module:
For each unit the operating mode can be selected: 
Toggle or Level controlled. In Toggle mode the rising edge of the CV input or operating the manual control button changes the state of the switch. In Level mode the switch state is defined by the voltage applied to the CV input (low voltage = I/O1, high voltage = I/O2) or by the state of the manual control button (not pressed = I/O1, pressed = I/O2). 
The modes are programmed very easily: Operating the Toggle/Level button of the program section displays the current state of each switch with the LEDs (left LED on = Toggle mode, right LED on = Level mode). 
Operating the manual control button of the switch in question changes the toggle/level mode.
In addition it's possible to define master/slave groups. In such a group the upper unit (= master) controls also the state of the following switches provided that they are defined as slaves. 
Master/slave programming is also very simple: Operating the Master/Slave button of the program section displays the current state of each switch with the LEDs (left LED on = Master, right LED on = Slave). 

Operating the manual control button of the switch in question changes the master/slave mode. 
When all 8 units are defined as master each switch is independent of each other. If for example the sequence is MSSSMSMS the control unit of the first switch also controls the switches 2, 3 and 4. The control unit of switch #5 also controls the switch #6, and the control unit of switch #7 also controls the switch #8.

Doepfer is also thinking about a small preset management with eight presets which store the states and modes of all switches. But they are not yet sure if this makes sense because the configuration of the switches is associated very closely to the patching of the sockets.

Date of Delivery: Spring 2017 
Price: ~ US$ 160.00 (Euro 150.00)

Doepfer A-135-4A/B/C Voltage Controlled Performance Mixer Modules Announced


The A-135-4A and B prototypes on display
at the Amsterdam Dance Event in
October 2016
In a previous blogpost I was rather excited about my own new A-138p/o Performance mixer combo.
I bought i just right before I knew that Doepfer was working on a voltage controlled version of this module...

On first impression, the new A-135-4A Voltage Controlled Performance Mixer looks quite the same as the non-cv-controllable A-138p Performance Mixer, only with extra LEDs for displaying the incoming CV voltages for all parameters (except Gain).

Module A-135-4B is the CV-input module, where 16 different control voltages can alter 16 parameters on the A-135-4A Mixer... The modules must be connected via an int 20pin ribbon-cable.

Module A-135-4C is a four-fold envelope follower with adjustable attack and release time for each channel.
The main function of the module is to derive four envelopes from the A-135-4A audio input signals. These voltages can be used to control parameters of the main module A-135-4A via the CV input module A-135-4B2. Typical applications are ducking (e.i. the signal of one channel is used to mute another channel more or less), as well as compressor and expander functions.

A-135-4A/B/C VC Performance mixer prototype
with the A-138o Output module
A-135-4B CV Inputs Module close-up
The modules of the A-135-4 series can be combined with the (non voltage controlled) mixer modules A-138o/p so that these can be used as output module for the A-135-4A. A-135-4A and A-138p can be connected together to the same A-138o to obtain e.g. four fully voltage controlled channels (A-135-4A) and four manually controlled channels (A-138p).

This combo will probably available before spring of this year.

Doepfer A-138p/o Performance Mixer Combo

The latest addition to my modular system is the A-138p/o Performance Mixer set of modules...

A-138p and A-138o
Performance Mixer
Modules A-138p/o are a simple performance mixer that I use as and end-mixer for all the signals coming out of my A-100, and for merging my TB-303 audio, before it all goes into my mixing-desk.

Module A-138p is the 4-fold input module, A-138o is the output module that can be combined with one or more A-138p.
I read somewhere that the module didn't start off as commercial product, but as a personal hobby-project of Dieter Doepfer who just needed this module for himself... It did go through quite a few prototype stages before it was released in this final form.

The A-138p has 4 input channels, with separate controls and a mute
switch for each channel.
A-138p/o in my current setup, with
the aux send/return patched through
the Qu-Bit RT-60 DSF Multi fx
The controls are for Gain (control to adapt different audio levels -also for external signals), Level (the main volume control), Aux and Panning
An internal jumper for each channel lets you choose between Aux pre/post main Level control.
There is an internal connection to the output module and to other A-138p modules
The A-138p requires the A-138o Output module (no stand-alone use)

The A-138o Output module features level controls for Left, Right and Aux,  and output sockets for Left, Right and Aux (3.5 mm mono sockets), it requires at least one A-138p (no stand-alone use)

I must say that I am extremely happy with these new modules. It's just what I needed to create an easier workflow in my system.
I especially like the Aux send/return function, which makes it a perfect companion for my Qu-Bit RT-60 DSP multi-effects module, but you can also use it for sending audio to a BBD-module, a filter or spring reverb for example.
Alternatively the Aux send can be used for pre-listening in combination with a headphone.
Like any other Doepfer module this one is easy to use too, the controls are very basic and straightforward. These modules are now the heart of my A-100 system.

About a week after I ordered mine, the word got out that Doepfer was working on another version of this module (A-135A/B/C) with dedicated CV inputs for each parameter and a Quad Envelope follower module with attack and release controls for each of the 4 channels.
Some prototypes of these modules are already touring through the world, I did see one in the Alex4 rack at the Amsterdam Dance Event in October of last year.
You can read more about that in my next blogpost, but I must say it looks promising.
At the moment I don't really need such a module. but I do see some exciting possibilities in these modules.

Happy New Year From PatchPierre

Hi there, it's me again... Happy New Year!

You might have noticed that I havent posted a lot in the last 2 years...
It's been a rough time for me since the sudden loss of two parents within a relatively short time-span and I really needed some time to get myself together... to set things straight, finding myself and selecting priorities... even my regular work suffered from this breakdown.

It took a while to understand it all, and to get a better grip on it, and it's sometimes still not very clear.
I think I have found a way to cope with most of it now... although the slight autism that I have (ADD-like) doesn't make it easy for, especially in crowds with lots of people I don't know...
On my journey I also (re-)discovered the beautiful woman that has always lived inside of me and that i need to accept and cherish... more on that maybe later... I'm not considering changing the name of the blog to PatchPetra.Net 😇 (...yet), but you might spot me somewhere at modular events in the near future looking a bit different. Please feel free to say hello and ask me anything, but try to adress me then as Petra...

But back to that blog;
When I started PatchPierre.Net in 2010 there were only a few blogs completely dedicated to modular synths... I mainly remember Navs Modular lab (http://navsmodularlab.blogspot.nl/) , and Synth.NL, where Michel blogged about his own builds. I was (and still am) a fan and frequent visitor of MatrixSynth.com and MuffWigger.
The Eurorack boom hadn't really taken off back then and i had a lot of dedicated followers and readers.
Although I was mainly focusing on my own (Doepfer) modules at first, I always kept an eye out for new modules and tried to keep up with all the news and post about evrerything... but that seems impossible nowadays. I'll leave that to others, with some exceptions of course.

The beating heart of my studio today 
2017 will be the year that i will return to posting on a more regular basis, by taking at least one day
off from work in every two weeks, so I can totally focus on the blog and making new video's.
I can't promise too much, but I aim to post somewhere between 100-150 blogposts this year.
I will start off with some of my new equipment that I haven't blogged about yet...
My new studio-setup is now almost completed and expanded with an Arturia Beatstep Pro and an Akai MPC Touch sampler.
A perfect setup for the kind of stuff that I like to do...
I discovered I'm not much of a noodler/wiggler but that I feel more related to live techno performers and live jazz musicians... Hence my interest in the somewhat weird time-signatures (oh I just love 4/5th and 7/8th) and long repetitive jamsessions.

I will also be opening some space for ads on the blog, with an average of around 10.000 pageviews per month over the last 3 years (15.000 last december, without even posting much) I think it's worth another try... Contact me for info at Pierre@PatchPierre.Net
The donations-page is also still open, thanks again to the people who have already showed their support in the past.

So... that's one of my New Year's resolutions. You can expect new updates pretty soon I guess.
I hope you will look forward to it as much as I do and perhaps you will show some support by re-tweeting/re-posting what you like most.... Thanks in advance! xxx

Have a great 2017!

Pierre / Petra / PatchPierre / NetPierre

Oh... and this!

Livestock Electronics at ADE SoundLab

Daniel from LiveStock Electronics showing me their range of modules
It's always fun to meet new Modular manufacturers, especially when they're from the Netherlands
and/or Belgium.
Last Saturday i had the chance to talk with Daniel Mulder, one of the co-founders of LiveStock Electronics at a special Amsterdam Dance Event SoundLab showcase event.

Livestock Electornics was founded in early 2016 and is about to release their fist modules at the end of this year. Their modules are heavily inspired by the chiptune and DIY-scene, and Daniel showed off a few interesting sounding new modules... you can find all info on their website.

LiveStock Shepard
The SHEPARD is a 4-channel step sequencer specifically designed for live settings.
This module is great for polyphonic and polyrhythmic sequences. And has a lot more to offer than just triggering notes and gates!
The interface is divided into two modes, play and edit mode. In play mode loops of several channels can be selected at the same time, and easily duplicated. While edit mode gives you the possibility to create dynamic sequences for each channel. Gatescan be delayed or held, notes can be pitched, and sequences can be of different lengths, speeds and directions. Each step can also send two control voltages with a optional glide while triggered, this gives you the option to control other modules during a sequence.

The memory has room for 8 tracks with each 16 loops of 64 steps for each of the 4 channels. The loops and tracks can be selected during play mode, or controlled through cv input.
Note: This module is moddable with the Arduino IDE and modding manual (available after release).
LoveStock also supports users in modifying their modules...

LiveStock Bang
BANG is a digital wavetable oscillator in which you can create and share your own wave libraries using the Bang Application, or simply download user wave libraries from our website. Once uploaded to the Bang Module you can use the waveshaping algorithm built into Bang to create new waves using the waves in the library.
LiveStock Electronics Bang Demo video by Paul Tas: www.youtube.com/watch?v=ZlIF1jsUHz0

LiveStock Maze
MAZE is a routing and mixing module. Route audio, cv’s or gates to several outputs, determine their intensity and mix them together. Routings can be saved and selected by a knob or by using the cv input.

Felix
FELIX is a two 1:3 buffered multiple with attenuators.
Use this module to copy CV’s, Gates or Audio and change the amplitude or intensitywith the attenuators.

MIR and MIR Expander
MIR is a mixer, inverter and VCA. It has four 2:1 mixing VCA's with uninverted and inverted output.
MIR comes along with an expansion module, which gives you the option to change the amount of cv input and whether the VCA responds linear or exponentionally. Place the expansion board anywhere you like, you can also set the parameters on the pcband leave the expansion board out if you need to save some hp.

LiveStock Kepler


KEPLER is a unique low-pass filter with four poles that are individually
controllable with knobs and cv.
The sound can range from soft and clean sounding sweeps to highly resonating self-oscillating sweeps. The cutoff is even controllable with v/oct which means that you could use the filter as an oscillator.

​The LiveStock Electronics crew will tour some more through the Netherlands in the next few weeks with these new modules, so try to check them out at:
28/10 @ Bizarre Sound Creatures (Dutch Design Week) Eindhoven
02/11 @ Nerds on Stage Rotterdam

The Bang and Felix will probably be released in December or January. As for the other modules, the release depends on the next batch of prototype pcbs. If it goes as planned, you can expect them from January to August 2017!

Doepfer A-184-2 Voltage Controlled Crossfader / Triangle-to-Sine Waveshaper

More News fom the Superbooth event in Berlin (March 31st - April 2nd, 2016)

The A-184-2 Voltage Controlled Crossfader / Triangle-to-Sine Waveshaper is the combination of two functions and planned primarily as an expansion module for VCOs or LFOs (e.g. A-110-1, A-110-2, A-145, A-147-2).
A-184-2
The upper section is a very precise triangle-to-sine converter (thank's to Tim Stinchcombe who recommended this circuit).
It can be used to convert any triangle waveform into a (nearly) perfect sine. 
The converter is much better than the simple diode converter used in the A-110-1, A-111-1, A-145 and A-147-2. 
Two trimming potentiometers are used to optimize the sine shape. 
The converter should be assigned to one VCO or LFO because the trimming potentiometers have to be re-adjusted if the input level or DC offset of the input signal changes. 
If the trimming potentiometers are deliberately mis-adjusted it can be used also as a waveshaper for non-sine waveforms (e.g. sine-shaped at the top of the signal and a peak at the bottom, even voltage controlled by applying an additional voltage to the waveshaping circuit, "circuit-bending" notes will be available).

The lower section is a Voltage Vontrolled Crossfader. 
It has two inputs A and B. The two signals are mixed together with variable percentage. When the manual control CF is fully CCW only signal A appears at the CF Out socket. When the manual control CF is fully CW only signal B appears at the CF Out socket. In the center position of the manual control both signal appear with the same level.
In addition a control voltage input CV with attenuator is available to enable voltage control of the crossfade.
Two LEDs display the crossfading shares of input A and B.
The crossfader uses two high quality VCAs (SSM2164). Inputs and outputs are DC coupled. Consequently it can be used for audio signals and slowly varying control voltages as well.

The sockets of the upper section (triangle and sine) are normalled to the inputs A and B of the crossfader section. That way the crossfader is used to fade between triangle and sine of the VCO or LFO connected to the waveshaper.
If other signals are plugged into the input sockets A and B these signals are used for crossfading.

The main application is to fade between two different waveforms of a VCO or LFO, but the module can be used for any other signals too as the waveshaper and crossfader sections are independent apart from the normalled sockets.

4 HP wide, Price: about Euro 80.00
Available around spring/early summer 2016 

This is a preliminary information about the planned module. The features are still subject to change and all specifications are still preliminary without any obligation !

New Doepfer High End VCOs A-111-2, A-111-3 and A-111-4 Thru-Zero Announced

Doepfer has announced two new High End VCO's at the Superbooth event in Berlin (March 31st - April 2nd, 2016)

The A-111-2 is based on the CEM3340 Rev G chip
There was a close cooperation between Doepfer and OnChip since 2015 regarding to the new re-issue of the CEM3340 and they received the first samples in January during NAMM for development.
The first production batch of the CEM3340 Rev G arrived 2 weeks ago and the production of the A-111-2 has started during the next few days (they are still waiting for the latest front panel and pcb samples). 
Doepfer expects the first modules to be finished around the end of July/August. 
The A-111-3 is also based on the CEM3340 Rev G ,and Doepfer is working on a Thru-Zero VCO based on the CEM3340 Rev G too (module A-111-4).

The Doepfer A-111-2High End Voltage Controlled Oscillator II is the successor of the obsolete High End VCO I A-111-1 and here are the most important features of the planned module:

Meet the Maker - Modular Synths panel with 6 Eurorack Manufacturers



At this year's Winter NAMM show, Vintage King Audio presented the TEC Tracks panel: "Meet the Maker -- Modular Synths".
This short (35 minutes) panel discussion, distributed by Sound On Sound, brought together 5 well-known modular synth makers to talk about the booming Eurorack format.

Panelists included: Dieter Doepfer (Doepfer), Dan Green (4MS), William Matthewson (WMD), Ryan McGuire (Vintage King moderator), Tony Rolando (Make Noise), Brandon Ryan (Roland) and Gene Stopp (Moog Music)

They talked a bit about the history of the Eurorack standard (with it's US-based Inch-metrics... lol), and the influence of live-Eurorack performers on new modules.
William Matthewson from WMD offered an interesting insight of what to expect in the future with new controls, like tactile things, body movement, gloves, the integration of virtual reality and other new futuristic techniques that can convert all kinds of signals into control voltages.

Interesting to hear was also the process behind the whole module-design and where Dieter shared his point of view about the pros and cons of the community-input, mentioning the importance of the Yahoo A-100 Usergroup (and his annoyance about it sometimes) and the creative input from live musicians like the icelandic band GusGus when it comes to developing new modules.
It reminded me of his work with the guys from Kraftwerk in the past, with the development of the Schaltwerk, the vocoder and other projects...

AQA ElektriX at Dancefair 2016

At Dancefair/Musicfair, I had the chance to talk with an engineer from AQA Elektrix, one of the more recent new brands in Eurorack, about their range of Eurorack modules.

Me and the AQA ElektriX engineer 
AQA Elektrix is a Eurorack Modular Synthesizer manufacturer that works closely with musicians. The modules by AQA Elektrix are inspired by classic circuits that get modified and developed further. They are also working on complete new designs with new functionality.
The modules are manufactured in Berlin, look very nice and the knobs feel solid as a rock.

AQA only released a few modules so far;
the TEG-1 / Triple Envelope Generator,
M/S-Matrix, a module that converts a Left/Right-Stereo-Signal into its Mid and Side Components
the QLFO / Quadrature Low Frequency Oscillator and the DUAL SVF / Dual 12 dB State Variable Voltage Controlled Filter

AQA ElektroniX modules
He also showed me their new 21 HP wide Dual VC Delay that produces some very cool and interesting 'dubby' soundeffects.
Used in parallel/stereo-mode it generates voltage controlled modulated spatial effects with it´s own special character.

Features:
- Delays can be routed in parallel or serial configuration (A => B or A II B)internal feedback with a 6dB HP and LP filter in series for each delay, feedback signals are attenuverted
using normalized feedback in and out jacks, the feedback loops can be opened to insert other stuff
feedback can be switched between parallel and cross routing between A and B
- Audio input attenuators for each Delay
each delay time can be independently controlled by knob
each delay time can be independently modulated by an attenuverted external control voltage
each delay time can be independently modulated by an attenuverted external control voltage
- Normalized audio signal Inputs
- Outputs for the delayed signals
- Outputs for the delayed signal and HP+LP filtered delayed signal (for feedback use)
- Normalized feedback-signal Inputs

Check out the video below for soundexamples.

DanceFair/Musicfair Pro Audio Summit Impression

Victor Coral
School of House
This weekend I attended the annual DanceFair/Musicfair Pro Audio Summit, the biggest in the Netherlands at the Jaarbeurs in Utrecht.
A gathering of more than 6000 music makers, industry professionals, 80 record labels and manufacturers of musical instruments, producer and dj gear.
It was the 5th time that Dancefair was held, and the first time that Musicfair joined in.
All together a great event for DJ's, producers and other fanatics for networking, learning and exploring, with inspiring workshops in different rooms and a nice Expo-floor.

We started off our Saturday quite relaxed with an interesting talk about the History of House, presented by Victor Coral from the Dutch School of House.
After that we learned a little more about audio-compression with some interesting views on side-chaining at a Pro Audio session.

DJ Magazine talk at the expo-floor
There was plenty of room for the younger audience and new talents with various production-sessions and workshops for the different styles of dancemusic by Hardwell and Chocolate Puma (amongst others) and a large demo-dropoff zone hosted by national and international record-labels.

The expo floor wasn't huge but filled with a wide variety of exhibitors.
It wasn't too busy on the Saturday, the people in the booths were very accessable for info and plenty of headphones were available for the public to listen to all the new synths and stuff...

Roland Eurorack Modules
Aira Modular, System 500
and Effectors
I had a lot of fun with (finally) playing around with the Moog Mother32, Korg Minilogue, the Novation MiniNova and BassStation 2, plus the modules from the Roland Boutique range JP-03, JX-08, and A-01.
Besides that, Roland showed the whole AIRA-range and a big rack with all their Eurorack modules including the  Aira Modular, System 500 and Effectors...

Arturia showed their Maxibrute for the first time in Europe.
The MatrixBrute is a programmable monophonic / duophonic analog synthesizer, outfitted with three ‘Brute’ oscillators, Steiner-Parker and ladder filters, three envelope generators, analogue effects and a matrix-style modulation matrix.

A short talk with Andy Mac from Akai learned me that they will shoot new MPC-Touch tutorials next week... I hope they will be online soon, as the last 4 Basic Workflow Tutorials that they released (a few weeks ago) were pretty useful for an MPC-noob like me, someone who is totally unfamiliar with the whole MPC-workflow.

One of the 2 Doepfer cases at the Alex4 booth
The most interesting booth (for me) was the one from European Eurorackdistibutor Alex4 that showed a diverse range of Eurorack modules from brands like Doepfer (with most of their new modules), AJH Synth, Verbos, Endorphin.es and Vermona
That last one als showed the prototype Vermona TwinCussion, a percussion module that is capable of very nice 'syncussion' sounds.
DJ/Producer Lucien Foort
The modules from the Austrian Birdkids brand were also on display at the Alex4 booth and the engineer from AQAElektrix showed me their full range of Eurorack modules. More on this in my next blogpost.
Allert from SonarTraffic, who also helped out at the booth  took the time to explain the interesting concept of their studio at Kytopia.

We spent the last hours of the day back at the workshop area from the Herman Brood Academy, where Lucien Foort (from Quadrophonia and more) presented a workshop. He first went through a short history about modular synths, up to the recent Eurorack-boom before he gave an intuitive tutorial on how to integrate modulars in your curent DAW setup.

Overall it was a great atmosphere at the whole event with almost everything you'd expect, including overexpensive drinks and food... and yesssss.... BoothBabes! :)

Doepfer A-106-5 12dB SEM Filter Special Edition

Temporarily a special edition of the Doepfer A-106-5 12dB SEM Filter is available. It is equipped with a stylish Oberheim-style cream-coloured anodized front panel and black knobs.

A-106-5 SEM
Filter
Special Edition
Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM
module.
The filter is equipped with a band pass output and a combined low/notch/high pass output. 
For this output a control knob defines the relation between low and high pass signal. 
If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. 
The module does not feature self oscillation in contrast to most of the other filters of the A-100 system. 
The module generates a distorted audio signal if the level control is set to about 50% (i.e. center position) or more with A-100 standard signals like VCOs.

Inputs: Audio In, CV1 In without attenuator, CV2 In with Polarizer
Outputs: Bandpass Out, Low/Highpass Mix-Out
Controls: Audio Attenuator, CV2 Polarizer, Frequency, Resonance, LP/HP Mix

You can find my review of the original A-106-5 module HERE

Doepfer A-184-1 Ring Modulator / S&H/T&H / Slew Limiter Combo

Another unexpected release from Doepfer

A-184-1
A-184-1 is the combination of 3 functions which are actually already available in other modules (e.g. A-114, A-148, A-170). In many systems it's not necessary to have two ring modulators (A-114) or two S&H units (A-148) or two slew limiters (A-170) available. That's why we have compiled these function in one small 4 HP module.
The upper section is nothing but half of an A-114, i.e. a ring modulator with the usual X/Y inputs and the X*Y output.

A-184-1V
The lower section is a Sample & Hold (S&H) / Track & Hold (T&H) unit followed by a slew limiter.
An internal jumper is used to set the mode to S&H or T&H. In S&H mode the unit picks out a sample from the voltage at the SH input at the rising edge of the trigger signal input. In T&H mode the output follows the input voltage as long as the level of the trigger signal is high.
As soon as the trigger signal turns low, the last voltage is stored.
The trigger input is internally normalled to high, i.e. the unit works as a slew limiter in T&H mode when no trigger signal is applied.

The module will be available in the new Vintage Black colour-scheme too :)

Price: ~ Euro 90.00
Date of delivery:  spring 2016

Downloadable Frontplate Templates for Doepfer Modules Announced

Doepfer A-168-1, A-110-6, A-110-3, A-121-2 and A-184-1
with custom frontpanel designs


You might have noticed the colorful new frontplates on the Doepfer website recently.
I had almost mistaken them for new Special Editions, but Doepfer clearly writes:

"The custom versions of a few modules featured on the Doepfer website are only a design study made with a self adhesive foil, printed by a color laser printer.

That way the customer will be able to design "his" personal module by printing his design on an self adhesive foil and stick the foil to the module (for this the module has to be dismantled).
There are no plans to offer these versions of the module, but they do plan to offer suitable templates for download."

Knobs in different colors are also still available so your only limit will be your imagination.

I wonder how Doepfer will further develop this idea... i.e. if there could be such a thing as an online Doepfer Template designer tool or such... Hmmm... Nice.

The first examples look very impressive IMO...
