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.

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 !

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...
