More Darkness: Doepfer MAQ16/3 Dark Edition
It seems that Doepfer is extending their successful 'Dark'-product-range even more with their latest announcement.
A new version of the MAQ16/3 MIDI Analog Sequencer will be black and feature Dark Energy-style knobs.
There's not much additional info, but i guess the inside of this fantastic sequencer will stay the same.
It looks great, and this is not the first time that a black MAQ will be available, but those models had the same style of knobs of the original MAQ, only in black...

New Doepfer A-157 Pictures / Dark Flow Announced
Doepfer posted their latest design and a bit more info on the upcoming A-157 (Mini Schaltwerk) Trigger Sequencer Subsystem modules on their website.
Hopefully the finished modules will be shown later at MusikMesse this year (10th-13th of May in Frankfurt, Germany)
The name 'Mini Schaltwerk' seems appropriate now, because it does look a lot like it's larger Schaltwerk brother.
" The LED/button matrix module A-157-1 is the core of the subsystem.
It is used to set or reset the trigger event on each of the 16 steps of each of the 8 rows.
The trigger output module A-157-2 outputs the 8 trigger signals and has an LED display for each trigger.
We will probably add a mute button or mute switch for each row that allows to turn the trigger output off/on independent for each row.
In the final version the modules A-157-1 and A-157-2 will be probably merged into one module only because both modules are essential for the subsystem.
The module A-157-1/2 (or the merged module that will contain both units) can be connected to a simple control module or a more sophisticated control module which is planned for the future (similar to the A-155 and A-154 conceptual design where the A-155 includes a simple control unit that can be replaced by the A-154 which offers a lot of additional functions).
At the beginning a simple control module A-157-3 similar to the A-155 control unit will be available.
It offers only the functions clock, start/stop and reset (both with manual controls and control inputs).
For this standard control unit the tempo (clock) is the same for all 8 rows, the direction is forward and the length of each row is 16.
We also plan a more complex control module A-157-4 that allows additional functions like 128 memories for trigger sequences, different clock/start/stop/reset for 2 or 4 groups of rows (e.g. common for rows 1-4 and 5-8, or in pairs), independent first/last step for each row, independent direction (forward/backward/pendulum/random) for each row, one-shot mode, LC display and so on.
But these ideas are very preliminary and we will have to find out which functions are essential."
Doepfer also mentions that there are also plans for an A-157 stand-alone version adapted to the design of Dark Energy and Dark Time with the same case dimensions and wooden side panels (provisional name "Dark Flow")
Release date: ~ fall 2013 (only A-157-1 ... 3, so far there is no release date available for the planned module A-157-4 and the stand-alone unit Dark Flow !)
Hopefully the finished modules will be shown later at MusikMesse this year (10th-13th of May in Frankfurt, Germany)

Blue LED Lights MIDI Controlled using a Doepfer MTC 64
James Bragg, member of the Doepfer Yahoo Usergroup recently shared his latest project.
He has just finished his 16-LED light-panel using a Doepfer MTC64 MIDI-to-Contact board.
The MTC64 is an universal MIDI interface that converts up to 64 succeeding MIDI note on/off or program change messages into 64 TTL voltages (0/+5V).
He has just finished his 16-LED light-panel using a Doepfer MTC64 MIDI-to-Contact board.
The MTC64 is an universal MIDI interface that converts up to 64 succeeding MIDI note on/off or program change messages into 64 TTL voltages (0/+5V).
The TTL outputs of the MTC64 can be used to control different switching functions.
With suitable drivers (e.g. switching transistors) relays, lamps, motors, electromagnets, even magnetic valves and so on can be controlled.
James only used 16 of the 64 switching contacts.
He explains: " When playing synth live I use an Akai MPC1000 sampler for backing beats and I wanted to synchronize lighting with it."
In the video he shows how it is all made.

Random Videos by Daniel Hofer
On a new YouTube channel by Daniel Hofer, a lot of interesting Doepfer-videos are popping up.
Mainly just wild audio-demonstrations without voice-over, but with very interesting sounds and great audio quality too.

MAQ16/3 FracRak Breakout Box

MAQ 16/3 FracRak breakout panels |
Especially when you change your setup a lot, you don't want to climb behind your 19"-rack to change patch-cables every time.
Of course there are always people who have figured out a solution for this.
This MAQ breakout panel that i found in an old Matrixsynth post came with a pair of custom made FracRak breakout panels to bring the MIDI jacks and the 1/8" Voltage Control and Gate jacks to the front of your FracRak panel for easy patching.
These would have fit perfectly next to your Paia modules for example.
It also had the necessary cables to connect to these panels from the back of the MAQ16/3.
![]() |
Sideview of theMAQ 16/3 FracRak breakout panels |
Theoretically it is possible to make such breakout panels for a Eurorack system.
The CV and Gate outputs would fit easily on one of those 8HP wide pre-drilled blank panels (A-180-style) that Doepfer sells as spare parts.
You can even put in a few extra switches for your own maximized customization experience. Your limit is your imagination.
Personally, I have long CV (red coded cables) and Gate (blue) wires coming out of my MAQ16/3 that come into my Eurorack system through multiple A-180 Multiples modules, but i can see the benefits of this module.
It might be worth investigating the possibilities of a Eurorack breakout panel a little more for a future blogpost.

Doepfer Pre-MusikMesse 2013 Announcements
Dieter Doepfer made a few announcements today about the upcoming new modules and about the MusikMesse 2013, that will be held from the 10th to the 13th of April 2013 in Frankfurt, Germany.
I'm looking most forward to the new A-157 Mini Schaltwerk prototypes, i cant wait until the are finished.:
Doepfer stated that they " ...will hopefully show the "large" version of the trigger sequencer A-157/miniature Schaltwerk (8 rows with 16 steps each).
The 8x16 button/LED board is ready but I cannot guarantee that the controller board will be also ready for the Musikmesse."
They will also show the prototype of the new version of the A-190-5 Polyphonic USB/Midi-to-CV/Gate Interface (with LCD) and the A-190-8 USB/Midi-to-Sync Interface at the Musikmesse in Frankfurt.
The other news:
The module A-171-2 (licensed copy of the Serge/CGS VCS) will be available about end of April or early in May 2013.
(It will be interesting to see how the Serge's new deal with TipTop works out - expect a surge of Serge for your Eurorack this year /PP)
The re-designed A-130 (linear VCA) is now delivered with a precision VCA circuit (SSM2164) instead of the CA3080).
The new A-130 is DC-coupled.
The re-designed A-131 (exponential VCA) is now delivered also with an improved VCA circuit (high end THAT VCA circuit instead of the CA3080).
The new A-131 is also DC-coupled.
The A-135 will be available from about May 2013 in a revised version with DC coupling of the signals and single outputs, i.e. it can be used also as 4 separate linear VCAs with manual gain, CV in with attenuator and signal in with attenuator.
Because of the DC coupling it can be used also for modulation signal processing (i.e. voltage controlled mixing of control signals).
So, a lot of updates, can't wait to see the first pictures of the A-157 combo coming from MusikMesse.
Are you going to MusikMesse this year and want to contribute pictures to PatchPierre.Net?
Feel free to contact me via the comments, email or Twitter, thanks in advance!

Alternative Controllers: Dmitry Shtatnov's Wob-Wob Fader
Dmitry Shtatnov uploaded a nice video from his latest DIY-project/invention.
He created a CV-source module that consists of an 8 HP front-panel with two faders, two separate mini-jack outputs and a switch.
The faders generate CV voltages, and each fader has its own output.
A switch is added to select between (regular) fader mode and so-called wob-wob mode with a 0V.-centre in the middle.
I must say it does create a nice effect, and IMO not only suitable for making Dub-Step...
Dmitry even shares the schemetics if you're interested in this project, contact him via his site or via YouTube.

R2 and R3 can be replaced with 4.7k to increase the sweep width. http://rpocc.ru/"

As an alternative you could also use the A-174-2 Modulation Wheels CV Source for this.
This module has 2 wheels, and comes standard as one spring loaded wheel with bipolar voltage output, and one wheel without spring with only positive voltage output as a standard.
For each wheel two jumpers are available: one for the voltage range (positive or bipolar) and one for the voltage plateau around 0 V.Another option to re-create this effect would be with an A-174(-1) Joystick module...

Using a Doepfer A-145 LFO as Swing Generator
I have decided to make a few short tutorials for the blog with relatively basic tips for your modular synthesizer.
The first video in this series shows how you can use an LFO as alternative 'Swing Generator'
I used a Doepfer A-145 LFO to show the principle.
The A-145 can do a great job as a (continuous) envelope generator, especially when using the reversed saw-tooth wave.
In the video the TB-303 is playing, the A-100 is playing the same pattern via the TB-303's CV Output.
The Gate from the TB-303 is fed into the Reset In on the A-145 so each time this module receives a Gate signal, it starts a new cycle.
Slow LFO cycles (Low mode) will result in longer envelopes and faster LFO's will result in interesting (swinging) rhythmical discoveries.
