Doepfer Superbooth 2019 Slim Line Announcements

This year Superbooth takes place again in Berlin from May 9-11th.
As promised in a recent interview with Dieter Doepfer, the company will be focussing on the public demand for smaller modules this year.
Especially the live Eurorack performers would love to see these new modules, which are basically smaller versions and re-designs of Doepfer's 'greatest hits'.

The first batch of Slim Line modules will include:
A-111-6, a miniature Synth Voice, quite similar to the A-111-5 and Dark Energy in just a 10 HP wide panel, and the following 4HP wide modules;

A-118-2 Noise Generator/Random/Sample and Hold module
A-121-3 12dB Multimode filter (a la A-121-2 but with smaller knobs))
A-130-2 Dual Liniar VCA
A-138i Interrupting mixer, a four channel mixer with an additional mute switch for each input
A-138n Nano Mixer, a simple four channel mixer, which can be used with either control voltages or audio signals.
A-145-4 Quad LFOs can be treated as a slimmed version of the quad LFO A-143-3 as it has similar features available
and the A-182-2 Quad Switch, a passive module that contains four changeover switches.

The History and Future of Eurorack Modular Synths with Doepfer by @DivKid and @Flixxx

Early contributors to this blog DivKid and Felix from the Tuesday Night Machine finally had the time to have a talk with Dieter Doepfer at a  recent Thomann event... 

" A rare moment of free time and having great people in the right place at the right time here's an interview with Felix of Tuesday Night Machines talking to Dieter Doepfer, THE CREATOR OF EURORACK at the Thomann Synth Reactor #TSR19 event. 

Felix and I wanted to chat to Doepfer about both his history (the history or Eurorack), his current polyphonic modules, future module sand ideas and a quick look at what the future of the Eurorack might be. 

We also talk about the Elektor Formant DIY synth, the new Frequency Shifter module coming later this year, CV controlled LED lighting, Dieter was also the EU distributor for Doug Curtis' Curtis chips/components, Raul's World of Synths, favourite Doepfer modules and plenty more. "

Doepfer Polyphonic Modules - a conversation with Dieter Doepfer #TSR19 by MoltenMusicTech

Robin Vincent of MoltenModular had the opportunity to sit down with Dieter Doepfer, the inventor of the Eurorack format, and chat about modular with a specific focus on his new polyphonic range of modules. 

" Thomann took a bunch of YouTubers to their shop and told us to go play and make videos. 

So we did. 

This is straight to camera, one take, off-the-cuff, honest and fabulous. 

Thanks to Thomann for the opportunity and thanks to Moog for the loan of the ONE (that I then had to give back). 

Search for #TSR19 for more fantastic videos from fabulous synthesizer YouTubers. "

The Doepfer - Kraftwerk Connection

German Krautrock legends Kraftwerk and Dieter Doepfer have worked together for a long time.
As the only one in its industry Dieter Doepfer even may use their name for advertising purposes.

Florian Schneider (Kraftwerk) and Dieter

Dieter: One day i got a call from a Mr. Schneider who wanted to know if we could rebuild a special keyboard into a MIDI keyboard.
The caller was Florian Schneider of Kraftwerk. Schneider experimented much with speech synthesis, and had found a keyboard that was triggering speech sounds (phonemes) in place of letters.

Doepfer's miniature MMK2 keyboard for Kraftwerk

After the modification by Doepfer, Schneider was able to send signals to a sampler in which the sounds were stored.
In the end, the Kraftwerk operator could connect the phonemes with a sequencer into sentences.
Until it worked, Schneider had come several times to Munich, where they got to know eachother better.
Around that time, Dieter installed a MIDI-retrofit on their old EMS vocoder.
Also in the construction of the MAQ 16/3 analog sequencer with MIDI output, the company worked with the musicians.

Florian Schneider was apparently quite involved with the development of the 16/3, being regularly sent updates to the operating system and giving his comments in return.

Dieter: "Since then, we are allowed to use the name Kraftwerk to the device. But we do not want to overdo things"
In 1996 Florian Schneider also wrote a review for a German music magazine 'Keys' about one of the Doepfer company's newest items, the A-100 vocoder module and even contributed a short demonstration of the units capabilities on the free CD that accompanied the magazine.

During 2001-2002 Morgan Karlsson asked Dieter Doepfer about his collaboration with KRAFTWERK:

" Our collaboration with Kraftwerk started many years ago as we made some special designs for them (e.g. the miniature keyboards they use on stage for Taschenrechner/Pocket Calculator and a special phonetic keyboard for voice synthesis).

"Designed in cooperation with the
German Band KRAFTWERK"

The first unit we built in cooperation with Florian Schneider was the MAQ16/3. We built some prototypes and Florian tested them and told us what we would improve and which features are not required.
So we went many times to the KlingKlang studio in Dusseldorf until the final version of the MAQ was complete.

A similar cooperation - but not as close as with MAQ - was made for the SCHALTWERK.
(Kraftwerk also used/tested with a Doepfer MOGLI on stage around that time *PP)

Rumors are that the Doepfer logo was (partly) inspired
 by this 1983 Kraftwerk album font

The next cooperation was the A-100 vocoder.
We tested all of the vocoders of Florian (and that's a lot) and compared them to our A-100 vocoder prototypes (the first versions with different filter designs in quantity and filter response types, e.g. 10 band passes, 8 band passes and high/low pass, 13 band passes and the final version with 13 band passes and high/low pass).
And so we found a very good compromise between price and sound.
Even the very high priced vocoders sounded not significant better than the final A-129.

We learned a lot about vocoders e.g. that a treble boost of the incoming speech signal is very
important for a good vocoder effect (is now included in the A-129-5).
All high priced vocoders imply such a treble boost but the customers is not aware of this detail as there is sometimes no remark in the user manuals.
We experimented together with Florian with a 32 band graphic equalizer to find the best treble boost for good speech recognition and implemented it into the A-129-5."

Video: The Secret Doepfer Files

I recently found these 2 older videos with Dieter Doepfer from video collective "Open Video Medien Labor", an open non commercial platform for video art.

As far as I know it is an open project - step by step - which could possibly finish with a Doepfer movie.
I like the way it is filmed anyway... but i have the feeling that it might become a looooong project.
I contacted the makers and hope to follow-up this blogpost with more info.

Dieter Doepfer Live at SchneidersLaden/ Berlin

On December 6th of last year, SchneidersLaden in Berlin had Dieter Doepfer as a special guest.

Dieter baked cookies (yes), gave a modular beginner workshop, did a presentation of his latest products and performed an interesting liveset. 

You can see the  A-197-3 VCO controlled RGB LED prototype in this video too (the dynamic LED control start about at 6:40)

Schneidersladen uploaded four videos of the evening - all worth checking out!

Doepfer A-197-3 Controller for RGB LED Stripes

Interesting that Doepfer's latest modules include some cool small, nifty non-musical utility modules.

Last time they announced the 4 x USB eurorack power supply, and now this one:

" Module A-197-3 is a control unit for RGB LED stripes. The LED stripe is glued e.g. to the inner edges of the cases A-100P6/P9/PMS6/PMS9/PMS12 to illuminate the modules and patching statically or dynamically. Especially during live events the dynamic illumination in sync with the sound is an eye-catcher. Each color (red, green, blue) has available a manual control for the background brightness and a CV input with attenuator that enables the dynamic brightness controlled by other control voltages of the modular system. For example 3 envelopes can be used which also control the loudness or filtering of sound processing modules. But even other control applications are possible, e.g. LFO, random voltages, clock/gate/trigger signals, sequencer, Midi-to-CV.

These are the most important features of the module:
Control module for static or dynamic control of RGB LED stripes with up to 1m length (so far only this length has been tested, with a sufficient external power supply even longer stripes should be no problem)
Manual controls for red, green and blue (small potentiometers without knobs)
CV inputs with attenuators for red, green and blue (small potentiometers without knobs)
Note: the CV inputs are planned for CV signals (e.g. envelope generators, LFOs), not for audio signals with frequency selective processing like lighting consoles
Control LED for each color
supply via the built-in power supply of the case or external (wall-art) supply to avoid the additional current consumption for the LED stripes
(the LED stripes do not require a high quality supply like those built into the A-100 cases)
the external +12V can be connected via a socket at the front panel (i.e. the additional supply is located outside the case) or inside to the pc board (i.e. the additional supply has to be installed inside the case by the customer)
required max. current with 1m RGB LED stripes: about 800 mA @ +12V (all three colors full brightness)
the top left edge of the front panel features a gap for the lead-trough of the LED stripe cable. Therefore the module has to be mounted at the left edge of the case: top left if only the top edge of the case is used to glue the LED stripe, middle left or bottom left if the LED stripe is glued like a reverse "U" to three edges of the case
The pc board is equipped with a pin header which is used to connect the standard LED stripe that comes with the module

In addition the pc board is equipped with a second pin header with 1/10" grid which can be used to connect other LED stripes than the standard type. A suitable female connector with 30 cm long cables with open ends for free wiring is included.
The module is suitable only for LED stripes with 12V power supply and common anode (+12V) with 4-wire cables (+12V/R/G/B).
A suitable 1m long RGB LED stripe is added for free. Due to possible problems during installation (e.g. improper glueing/removing or folding of the stripe) it is not covered by warranty but should be treated as a free add-on.
An external 12V supply has to be ordered separately if required (5.5/2.5 mm connector, plus = center)."

Release date: early in 2019

Doepfer 4 x USB Power Module A-183-9

USB Power module prototype

Without any preliminary information Doepfer had one small surprise at the Superbooth event in Berlin last weekend.

Their latest module is a 2HP wide USB Power module.
This module has 4 USB ports directly on the frontplate, and has a LED light at the bottom that shows if the module is active or not.

The module can be used for powering other equipment like a USB-keyboard or any other stuff that uses 5v USB power.
Charging your mobile phone or tablet or powering one of those USB-powered lights or small fans is also possible.

Okay, the idea is not new... but knowing Doepfer this will probably be very competitively priced again.

There's no release date on this module yet (...it doesn't even have a name or number too) , but I guess it will be in production soon.

Source: https://www.youtube.com/watch?v=3NTQuN-Gwhw by  JustMusic.de

Edit May 18th, 2018
A-183-9 Quad USB Power Supply will be the name and number.

Note: The module requires an A-100 case with built in power supply A-100PSU3 ! Only this A-100 supply has the required +5V available.
Doepfer does not recommend the usage of an older A-100 case with A-100PSU2 as this would require the +5V adapter A-100AD5 and the max. current would be limited to 100mA.

Doepfer A-157-4 Module, Trigger Sequencer Midi/USB/control outputs Announced for Superbooth 2018

A wide range of more than 200 exhibitors is now preparing for the upcoming Superbooth event (May 03 until 05, 2018,) in Berlin.
The program for the three days consists of exhibitions, concerts, workshops, DIY and more.
You can find all info at https://www.superbooth.com/

Doepfer will be there too, ofcourse... and besides the already announced 'new' modules, they will also show a new expansion-module for the A-157 Trigger Sequencer combo (or Mini Schaltwerk), the A-157-4 Midi/USB/control outputs.

They will have a working prototype available that will be shown at Superbooth.

It offers the control signals Start, Stop, Reset and Clock as outputs so that the A-157 module combo can be used as master for other devices (e.g. A-154/A-155, another A-157 or other sequencers).
It also connects the A-157 to Midi (in and out) and USB.

Doepfer will be demonstrating the A-157-4 at the Superbooth controlling the instruments of a Roland TR-8 via Midi or USB.

The Doepfer booth number is O212.

Doepfer NAMM 2018 A-100 Standard Module Announcements

A-123-2

My third and last post about the New Doepfer announcements for NAMM 2018... (January 25/28 2018, Anaheim, Hall A, booth 10706)
The other 2 blogposts are about the  Dark Energy III and their new Polyphonic Modules...
Among the newly announced "Standard Modules" there are these little gems

The A-123-2 6/12/18/24dB Highpass Filter is an interesting voltage controlled highpass filter with four filter outputs (6, 12, 18 and 24dB slope). It also features voltage control of the resonance. These controls and in/outputs are available:

• Audio In with attenuator (Lev)

• Manual Frequency control (Frq)

• FCV1: Frequency control input (~ 1V/oct)

• FCV2: Frequency control input with polarizer

• QCV: Resonance control input with attenuator

• Manual Resonance control (Q)

• 6dB Output

• 12dB Output

• 18dB Output

• 24dB Output

A-140-2

The new A-140-2 Dual Micro ADSR

contains double ADSR type envelope generators behind a front panel with 8 HP only. Each ADSR provides these controls and in/outputs:

• Attack (A), manual control

• Decay (D), manual control

• Sustain (S), manual control

• Release (R), manual control

• Gate Input

• Retrigger Input

• CVT Input with attenuator (CVT = CV Time)

• Envelope Output 1

• Envelope Output 2

• LED control

By means of internal jumpers one can select which parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question). By means of another jumpers output 2 can be set to normal or inverted envelope).

Two more jumpers are used for the optional bus

access to the gate signal of the bus for each ADSR.

A-142-3

A-142-3 Envelope Controlled VCA Module A-142-3 is the combination of a simple AD/AR envelope generator and a VCA behind a front panel with 4HP only.

The type of envelope can be selected by means of a toggle switch between A/D (Attack-Decay) and A/R (Attack/Release). Another toggle switch is used to choose envelope or (free running) LFO mode.

The envelope output controls a linear VCA.

These controls and in/outputs are available:

• Attack control

• Decay/Release control

• AD/off/AR switch

• Envelope/LFO switch

• LED (envelope display)

• Gate Input

• Manual gate (momentary switch)

• Envelope Output

• VCA CV Input (normalled to Envelope Output)

• Audio Input with Level control

• Audio Output (the outputs of several A-142-3 can

be internally mixed together)

Furthermore, the modules that were already announced at Superbooth 2017 like the A-138s Mini Stereo Mixer and A-150-8 Octal Voltage Controlled Switch will be available pretty soon now...  and the A-180-9 got a final facelift and got upgraded from 12 to 14 channels through standard network cables.

Doepfer NAMM 2018 A-100 Polyphonic Module Announcements

Right in time for the upcoming NAMM exhibition later this week (January 25/28 2018, Anaheim, Hall A, booth 10706), Doepfer announced a few more interesting A-100 modules (next to the Dark Energy III news). Too many new modules for one blogpost, so I had to split it up into multiple blogposts... The next one will contain their new 'standard' modules.

The magic word for Doepfer this year seems to be Polyphony, because most of the new products are perfect companions for the highly anticipated A-190-5 Polyphonic CV/Gate Interface, a module that has been in pre-production for a loooong while now. 

On the Doepfer website we can still read the message We cannot yet specify a definite release date but hope that it will be available in 2011, from the early prototype stages.

We already know most of its features, i have been blogging about it since 2011, but here are the details once more:

A-190-5 is a Midi/USB interface that generates 4 gate signals and 12 control voltages to control up to four synthesizer voices (i.e. VCOs and associated modules like envelope generators, VCFs and VCAs) for polyphonic sound generation. 

The A-190-5 will be equipped with different polyphonic, duophonic, paraphonic and monophonic modes which are selected by means of menu buttons and the display.
For each channel a gate, a note controlled CV (1V/Oct.) and two auxiliary CVs (e.g. for velocity or controlled by midi control change messages) are available. In play mode the states of the four gates are displayed by four LEDs integrated into the buttons 1-4.
Firmware updates are possible via USB.

The A-111-4 Quad Precision VCO will be available soon too... adding 4 wide-range precision-VCOs to complement the Polyphonic module and was already announced at Superbooth 2017. Read all about this at http://patchpierre.blogspot.nl/2017/04/superbooth-2017-new-doepfer-module.html

A-105-4

Brandnew is the A-105-4 Quad SSM VCF filtermodule, their first polyphonic filter and contains four identical 24dB Lowpass filters (SSM2044 type).
The special feature of the 4 pole low pass SSM2044 is the patented so-called "true open loop design that delivers a characteristic fat sound not available from other devices"

This chip was used e.g. in these synths: Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2.2 und 2.3, Emu SP-1200, Siel KIWI,  DK600, Siel Opera 6, and the Simmons SDS5.

The first Prophets 5s used the SSM2040 - the precedessor of the 2044 - that generates a very similar sound. (source)  Version 3 of the Prophet 5 switched to the thinner sounding Curtis CEM3320. The Pro One also used that chip.

It has available common manual controls and CV inputs with attenuators for these parameters:
• Frequency (F)
• Frequency Modulation Intensity (FM)
• Resonance (Q)
• Audio Input Level (L)

Each filter has available a separate FM input as well as an Audio Input and Output. The FM input is typically connected to the output of the associated envelope
generator (e.g. A-141-4). The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input.

A-132-8

This allows also voltage control of the envelope amounts. In addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used.
The range of the audio input level control (L) allows also clipping/distortion with typical A-100 audio levels (e.g. from A-111-4) at the filter inputs.
Even this parameter is voltage controllable as well as the resonance (Q).
Application: polyphonic patches (four VCFs with same parameters)

Another new Polyphonic module is the A-132-8 Octal VCA:
The A-132-8 contains four VCA pairs. Each pair includes two daisy-chained VCAs. One VCA has a linear control scale, for the second VCA linear or exponential control scale can be chosen by means of jumpers.
Doepfer decided to provide two VCAs for each voice because usually one VCA is required for loudness envelope and a second one for velocity (or another function).
For each VCA these in/outputs are available:

A-141-4

• CV Input VCA 1
• CV Input VCA 2
• Audio Input
• Audio Output
Audio Sum Output is also available.
The module features two Initial Gain controls, that enable the opening of the first (G1) and/or second VCA (G2). This is necessary when the VCA in question is not in use (i.e. no external CV available). Otherwise the VCA would close. They are also useful for testing polyphonic patches.
Application: Polyphonic patches with two VCAs per voice.

The A-141-4 Quad Poly VCADSR contains four ADSR type voltage controlled envelope generators with common manual controls and CV inputs with polarizers for the parameters Attack (A), Decay (D), Sustain (S) and Release (R).

Each of the four envelope generators has available a gate input, a control LED and an envelope output.
Application: Polyphonic patches (four envelope generators with the same envelope parameters to control four VCFs, VCAs or other modules)

New Podcast: Why We Bleep by Mylar Melodies

I've been a long-time fan of Mylar Melodies. and his (Eurorack) video-productions, and yesterday he released the first episode of a brand new monthly podcast interview-series.

The new show is called Why We Bleep, and in it he meets electronic music makers and the people who make their equipment.
He explores their experiences, their processes, and see what can we learn from them.
"The show is inspired by an eternal struggle to get better at making music. To better understand the mysterious, unique and amazing people behind the equipment and music that we love. And to better understand where music making might be going.", according to the creator.

The podcast is available on iTunes, YouTube, and HERE on his site, and takes the form of a conversation recorded in-person, and also captured on camera where possible.

The first episode starts with meeting @musicthing Tom Whitwell, from Music Thing Modular, open source electronic musical instruments: http://musicthing.co.uk/modular/

Next episode will be Justin Owen of Abstract Data, Abstract Data designs & manufactures electronic musical instruments & effects in Eurorack Modular and Desktop formats.

Doepfer Dark Energy III Announced

Doepfer announced some interesting new stuff for the upcoming NAMM  exhibition later this week.

(January 25/28 2018, Anaheim, Hall A, booth 10706)

I will post the new A-100 modules in another blogpost, but first the exciting Dark Energy III

Dark Energy III is the successor of the Dark Energy II, a monophonic stand-alone synthesizer with USB and Midi interface. Main differences between II and III are an

improved VCO (no warm-up period, additional triangle waveform, wider frequency range), resettable LFOs, improved ADSR and a lot of internal access points for DIYers.

This will make it easier for DIY-ers to create their own breakout boxes with extra functions, like Organzoner did a while ago... He posted a great video with a step-by-step tutorial on how to expand the capabilities of the Doepfer Dark Energy 2 by adding a breakout box...

The filter of the Dark Energy II has been unchanged.

The sound generation and all modulation sources are still 100% analog, only the USB/Midi interface contains digital components. 

􀂃 VCO:
o Triangle based, 10 octaves frequency range
o Tune control and Octave switch – 1 / 0 / +1 octave
o FM input with selectable source (ADSR / off / LFO1)
o Manual PW control and PWM with selectable source (ADSR / off / LFO2) for rectangle wave
o Waveform switch
o Additional external CV inputs for frequency and pulsewidth of the rectangle
􀂃 VCF:
o 12dB Multimode VCF with continuous mode control (lowpass – notch – highpass - bandpass)
o Manual Frequency control and FM with selectable source (ADSR / off / LFO2)
o Resonance control, up to self oscillation
o Additional external CV and external audio input
􀂃 VCA:
o Linear control scale
o Manual Amplitude control and AM with selectable source (ADSR / off / LFO1)
o Additional external CV input
􀂃 Envelope:
o Improved ADSR type with 3-position range switch
o Additional external gate input
o Control LED
􀂃 LFO:
o Two resettable LFOs (external Reset inputs)
o manual frequency control and 3-position range switches
o Waveform switches triangle/square
o LED controls

Superbooth 2017 New Doepfer Module Announcements

From April 20-22, 2017 the second Superbooth takes place in Berlin.

Doepfer announced the new modules that will be on display there... with some very exciting new toys.
Some of the new products were already presented as prototypes at NAMM and are now available (e.g. the voltage controller performance mixer series A-135-4). But they will also show some new gear in Berlin (e.g. the quad VCO A-111-4, the micro keyboard A-173-1/2, the miniature stereo mixer A-138s and the low cost versions of the monster cases).

A-111-4 Quad VCO

A-111-4 contains four precision VCOs with 10 octaves range and has individual controls, inputs and outputs for each VCO available as well as common controls.
After all the A-111-4 is very similar to four A-111-3 with built in output mixers for the three waveforms and a common control unit for all VCOs. Controls, inputs and outputs (individual for each and common for all VCOs): 1V/Octave CV input Octave switch (+1/0/-1 octave) Tune control (range internally adjustable by jumpers: 2 semitones / 1 octave / 4 octaves) Modulation CV input (common unit is fixed to FM) Modulation destination FM or PWM (only for the individual VCOs) Modulation intensity Triangle output Sawtooth output Rectangle output Sync input (only for the individual VCOs, internally selectable hard or soft sync, CEM3340 hard sync type)

Typical applications: fat sounding monophonic VCO with the possibility to adjust intervals paraphonic patches (all four VCOs processed by one VCF/VCA) full polyphonic patches in combination with the polyphonic CV interface A-190-5 Date of Delivery: summer 2017 Price: ~ Euro 400.00

A-138s Stereo Mixer

A-138s is a simple but useful 4-in-2 panning/mixing tool. It has four inputs available with level control knobs plus a stereo (L/R) output.

A-173-1/173-2 Micro Keyboard

A-173-1/2 is a module combo that is used to generate a manually controlled
1V/Octave CV signal and up to 15 manually controlled gate/trigger signals.
Typical applications are the transposition of a sequence by means of the CV output (without the need of an external keyboard and CV interface) and the manual generation of gate/trigger signals for start, stop, envelope generator triggering and other trigger tasks. A-173-1 is the transmitter module and is made of a 1 ½ octaves micro keyboard and an octave switch. A-173-2 is the receiver module and generates several gate/trigger signals and a 1V/Oct. CV signal.
The upper section of the module is used for the gates/triggers which are controlled by the corresponding buttons of the A-173-1.
Each output can be programmed as gate (pressing/releasing the corresponding key turns the gate on/off) or toggle (pressing the corresponding key changes the state) or trigger (pressing the corresponding key generates a short trigger signal).
The state of each output is displayed by an LED. The lower section of the module is used the generate a 1V/Oct. CV signal and gate signal in the usual way.

Prototype

By means of the learn feature of the A-173-2 (i.e. defining the key for 0V CV) a few buttons can be separated from the CV generation section so that these buttons only control gate/trigger outputs without affecting the CV.
That way e.g. start/stop or other triggers become independent from the CV section. The modules communicate via standard midi note on/off messages and are connected internally by means of a 2-wire cable. That way the modules can be mounted at different positions within the case. Date of Delivery: summer 2017 Price: ~ Euro 180.00 (both modules)

Also a prototype of a new Multicore was on display, but the module has been updated, so the info here is old... Find info about the definitive 2018 version HERE

A-180-9 is another simple but useful tool. It is used to connect up to 12 signals between two different
For operation two of the modules (male and female version) and a Sub-D cable with the required length are required.
Because only male/female Sub-D cables are common on the market also one male and one female version of the module is required for the connection.cases by means of one standard Sub-D cable only. That way it's possible to pre-patch e.g. two (monster) cases and connect all signals, that are required in both cases (e.g. clock, start/stop, master CV) by one cable only instead of 12 individual patches. The module is fully passive (no power supply required) and simply wires the 12 sockets to 12 pins of the Sub-D connector.

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.

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...

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 or have the HP space for all of them. 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!
