Animodule SOB Filter Videos by @DivKid

It's good to see that more and more people start making really interesting Eurorack tutorial videos lately.
DivKid started a new series last month but i kinda missed it back then.
Here's a nice set of videos with Animodule SOB Filter tutorials.

Video 1: EURORACK MODULE - Animodule - SOB Filter Part 1

" The Animodule SOB filter is a pretty amazing bit of kit, 2 inputs that can clip with a wavefolder, state variable filter and tonnes of personality and character. It can handle smooth well but for me excels at more driven and characterful filtering. It also passes CV acting as a slew limiter and self oscillates creating a crude oscillator, some heavy percussive thumps and hardcore kicks along with going really slow to make for a useful LFO should you run out mid patch.
Subscribe to the channel for more and always feel free to comment."
Video 2: EURORACK MODULE - Animodule - SOB Filter Part 2

" Here's part 2 of the SOB Filter overview video. The SOB is a great state variable filter (with built in wavefolder) for eurorack modular systems from AniModule.
Any questions or anything feel free to comment."

Video 3: EURORACK MODULE - AniModule - SOB Filter's Wavefolder
" Here's a more in depth look at the wavefolder built into the AniModule SOB filter. It's a great filter but (hopefully) as you'll see in the video the wavefolder is great too. Here's some oscilloscope action of analogue waveforms (static and amplitude modulated) going into the unit with external and internal mixing along with modulation to create some moving and morphing wavefolding.

The Rest: Alesis MMT-8 Sequencer

Alesis MMT-8 Multi Track MIDI Recorder
The Doepfer A-100 is not the only equipment in my studio.
Although I am not a collector, I do have some other quite interesting (classic) machines which I review in this section called 'The Rest'
This is the second installment, find part one (about my Waldorf Pulse HERE)

The Alesis MMT-8 Multi Track MIDI Recorder was released at the end of 1987, together with its 'brother', the HR-16 Drummachine.
It is a very reliable sequencer with 100 pattern and 100 song memories and almost as reliable as my old trusty Atari ST computer, which has been the most stable sequencer I ever had... :-(  ...may it rest in peace...

" The MMT-8 is a simple MIDI sequencer that is still used today by some of the biggest names in electronic music (Orbital, Moby, Jimmy Edgar, Autechre and Carl Craig.) because of its simplicity, durability and reliability.

It's a pattern and song based sequencer with 8 separate tracks and each of the tracks can carry 16 channels of Midi info which makes this more like 128 tracks.
Tracks can be muted during playback giving you a lot of performance control for a live situation."

I bought this sequencer second-hand about 15 years ago for around 100 Dutch Guilders (45 Euro), and tried it in my setup for half a year or so, in cooperation with Cubase on my PC with a 4x4 M-Audio MIDI breakout box.
My whole workflow was different then, I tried to get the most of my set by using most MIDI-channels of every synth I had, so i ended up using Cubase more than i did use the MMT-8.

Now that my setup has changed into some kind of minimal live-jam-setup i am really considering integrating this fun little sequencer back in my setup again as a main sequencer.
At the moment my small setup is MIDI-synced via my Roland R-8 drummachine, with my other synths/sequencers playing loops, but it's still pretty basic.
With an extra sequencer I will be able to put more (and longer) melody-lines in my music.
I haven't tried it yet in my current setup, but i think this will work...
My main concern is that the MMT-8 only has a single set of MIDI In/Out/Thru connectors, so i have to put all my machines in a chain-setup.
I just hope this doesn't cause too much lag in the synths that are last in the chain.

Alesis MMT-8 with a quick
manual under the hood
From my own experiences I already learned that the first in the chain to prevent an audible lag should be my Drummachines (R-8 and a Machinedrum), but after that i need to attach at least 5 more synths.
I hope this works out well... I might need to invest in a MIDI-splitter though.(mainly for synchronizing-reasons)
If it doesnt' work out the way I want might want to sell it.

A second-hand MPC-1000 (or newer) is on my wishlist for a long time, but i still don't have the funds yet. #priorities
Multiple MIDI-Outputs are better, and the MPC's have multiple MIDI-Inputs too, which means I can also attach more of my keyboards (JV-90, Prophecy and BassStation).
The built-in sampler will mean that don't need my current E-Mu ESI-32 sampler anymore and that i have to copy over all the samplebanks that i already built for that....

I hope to have my new setup configuration with the MMT-8 ready at the end of next month (depends on the weather too), and I'll let you know how it all turned out.
You will probably spot it in my next live-jam-videos...

First i still need to get my mixing-desk fixed. That's another thing that's gonna cost me a small fortune.
More soon...

Aesis HR-16/MMT-8 book
by Craig Anderton
I'm still looking for this book by Craig Anderton about the MMT-8/HR-16(B)
It seems to be the only printed book relating to the MMT-8.
It is split into four (2x2) sections and the section relating to the MMT-8 doesn't give any more information about the MMT-8 or how to use it than the manual does.
However, certain features are expanded upon and explained in greater detail than the manual.
Overall, the book makes a good introduction for beginners to MIDI and the MMT-8, and is a handy reference for more experienced users.

Random Video: Guitar Straight into the Doepfer Analog Synthesizer

Here's an older video (from August2010) that explains how you can simply play your synth with a guitar by only using a Doepfer A-160 Clock Divider.
This seems to work great and outputs a nice square wave, and logically, this works best with single notes (great for solos after some good practicing)
After the A-160 module you can route the sound to anywhere you like... just plug and play!

Video: Guitar Straight into the Doepfer Analog Synthesizer

" Ok Ok, this is crazy... This video shows you how to (without any 'special' modules whatsoever) play an analog mod synth with a regular ol guitar. I discovered a very common, but unusual module to convert the guitar signal into audio: the clock divider... insanity ensues...

More A-190-4 MIDI-CV/Gate/Sync Interface Specifications

Last year, quickly after the A-190-4 prototype suddenly appeared in the wild, i already contacted Dieter Doepfer about some of the specs of the module.

The Doepfer A-190-4 will be the new replacement for module A-190-1 which is no longer available.
The functions of A-190-1 and A-190-4 are nearly the same (Midi In, Midi Out, CV1, CV2, Gate, Clock, Reset), but the operation of the A-190-4 has been improved because a 3-digit LED display is available.

The current values of all parameters (like Midi channel, reference note, clock divider) can be read back and modified by means of up/down buttons.
In addition A-190-4 is equipped with an USB interface and the external +5V supply is no longer available.

A-190(-1)  MIDI-CV/Sync
The A-190-1 has 2  DACs (Digital-to-Analog Converters)
In the original A-190-1 DAC 1 is 'hard-wired' to receive MIDI note messages and convert them into control voltages available at CV output socket CV 1. This DAC has 12-bit resolution, which gives excellent tuning resolution (in steps of 1/4096th). As a rule, DAC 1 will be used to control VCO pitch.
DAC 2 can be assigned to your choice of MIDI controller. This DAC has 7-bit resolution (1/128th steps).

At the time (almost one year ago) Dieter couldn't tell much about the processing power and if any other functions would be available (arpeggiator? like the A-190-3), but this week I have managed to get a bit more info.
Christian Assall, software developer at Doepfer, was kind enough to explain a few more things about the A-190-4 via e-mail:

A-190-4 Prototype
- "The A-190-4 will have 2 new DACs... Because the development of the A-190-1 was now before more than 15 years, it makes sense to use modern pieces."

- "DAC2 will now also be 12 bit and will have a range of 0 ... 10 + volt ( but can also only use it for velocity/controller and things similar to the A190-1 , but not for pitch/tune controlling like the CV1 - so it's not possible to control two voices - because you also have only one gate ;-) - for polyphonic things we have the A190-5 in development"

About future firmware updates:
- "As the next development in schedule list is the A-190-5 - which is something like a 'great' brother of the A-190-4 - the A-190-4 has in most cases the possibility to inherit his features... it's more a question of what we and the users want and decide to include in a preferably easy to use CV-interface the A-190-4 should be... This also belongs to the topic arpeggiator."

The A-190-1 Arpeg. mode never got released 
About the somewhat hidden arpeggiator-function in the A-190-3:
- " It's more a cost-free present or an eastern-egg like thing than a real feature in my eyes, because it hasn't any dedicated switches or display for that - so I think it's for many users hard to use ...
But if you can - sure you can use it and you can do some arp. things without any additional devices/software ...."

- " We never released this feature in the A-190-1, mostly because of the not optimal user interface, that was not suited in our eyes for additional and such a complex features.
An arp. should have a dedicated/suitable user interface - otherwise it didn't make much sense in my experience/eyes.
Sure also the weak processor power was a reason, not to try with many tricks to get an arp. which is in timing and didn't interfere with the other functions of the module.
So, never to release, was more a matured consideration that came from practical experiences..."

The A-190-1 will be replaced by the A-190-4 from about April 2014.
As of April, the Doepfer BS basic systems will come with an A-190-4 installed...

Random Video: Epoch Modular 'Benjolin' with Doepfer A-143-9 and A-135-1 by isvisible

Another nice Eurorack video by isvisible popped up on Vimeo today:

Epoch Modular 'Benjolin' with Doepfer A-143-9 and A-135-1 from isvisible on Vimeo.
" I wanted to make a video showing off the many facets of the Benjolin, but got carried away with it and only covered a little bit.
There were only three modules used... an Epoch Modular version of the Benjolin (originally designed by Rob Hordijk), and two Doepfer modules, an A-143-9 Quadrature LFO which is modulating the VCA's in the A-135-1 Quad VCA / VC Mixer.
The A-143-9 is in turn being modulated by the Rungler out on the Benjolin.

Four audio channels were taken from the Benjolin and into the Quad VCA.
1 - LPF.
2 - XOR.
3 - HPF
4 - PWM
There was slight panning of the four channels in my mixer (Output 1 slight left, to output 4 slight right) then recorded with no external effects or any additional modulation."

Doepfer A-101-6 Six Stage VC Opto FET Filter/Phaser Announced

Another new module announcement from Doepfer.

" A-101-6 is a new filter module that uses so-called opto FETs to control the filter frequency.
A-101-6 Six Stage Opto FET VCF
Opto FETs are very similar to Vactrols but use light depending field effect transistors (FETs) instead of light depending resistors (LDRs).
A Opto FET is a combination of a light depending FET and a LED (light emitting diode) both put into a small light-proof case.

The advantage compared to vactrols is the much faster response of opto FETs compared to LDRs. 
This allows much faster attack/decay times and even FM effects. 
The disadvantage compared to vactrols is that the FET behaves as a normal Ohm resistor only for small levels. With higher levels the FET begins to distort.
Apart from this the notes mentioned on the Doepfer Vactrol Basics page are valid.

Module A-101-6 is made of six serial 6dB filter stages. The stages can be switched simultaneously to lowpass, highpass or one of two allpass types.
The following schematics show one of the six serial stages in the four possible modes:

A-101-6 Principle Schematics
The variable resistor shown in the schematics corresponds to the opto FET.
The type of filter is selected by two toggle switches or 2 control inputs.
The upper switch selects between lowpass and highpass provided that the lower switch is in the LP/HP position.
When the lower switch in the AP (allpass) position the upper switch is used to select between the two allpass types. Instead of the switches even external control voltages can be used (CV LP/HP, CV Allpass sockets).
For this the toggle switch in question has to be in the left position.

The brightness of the Opto FET LEDs and consequently the filter frequency can be adjusted manually (Frequ. control) and controlled by means of an external control voltage (CV) with attenuator.
The LED at the front panel reflects the LED brightness inside the opto FETs.

The resonance is controlled by the Feedback control up to self oscillation. By means of two trimming potentiometers the maximal feedback can be adjusted separately for LP/HP and allpass mode.
High feedback values can be used mainly in the allpass mode to obtain very extreme self oscillation sounds. Even an external feedback signal can be used instead of the internal feedback connection (FB In socket).

The Mix control is used to pan between the original signal (CCW position) and the effect signal (CW position).
In filter mode (LP/HP) this control is usually set fully CW.
In the allpass modes one obtains phasing sounds at center position or "pure" allpass sound in fully CW position."

Update May 6th 2014:
" thank you for your interest in the planned module.
Because of several suggestions by customers there will be probably some additions (like voltage
controlled dry/wet mix and maybe voltage controlled resonance/feedback).
So it will still take some time until the module is available.
An experienced A-100 user is currently about to try out the prototype (still without the additional voltage controlled features) and we wait for his assessment about the features of the module before we continue.
If the module is back I can do some demos." *source Dieter Doepfer

Release date and price for this module are not yet available.

The new Doepfer modules will be shown at #MusikMesse in the booth of their distributor Alex4 in hall 5.1, booth nr. C54

Doepfer A-127 BOM Filter Breakout Module Announced

Doepfer finally announced a few new modules for this year.
The first one is an expander-module for the A-127 Triple Voltage Controlled Resonance Filter, which has always been my favorite Doepfer filter...

Basically they took advantage of all the filter outputs that were already available in the original A-127 module, but not made available on the frontpanel.
I wrote about how i made my own A-127-expansion-board a few years ago in this blog, but this official board takes it to the next level, with even one more filter and separate audio outputs.

A-127 BOM Filter
Breakout Module
" For early summer 2014 the A-127 breakout module is planned.
This expansion module offers these new functions:
- additional notch filter for each sub-unit
- separate outputs for lowpass, highpass, bandpass and notch for each sub-unit
- separate audio input with attenuator for each sub-unit

The breakout module allows the separate use of each of the three A-127 filters.
In addition the filters can be patched parallel or serial.
Especially the serial connection of three notches generates very complex phasing-like structures.
For parallel filter connection the existing mixer of the main module may be used or an external mixer.
For serial connection the filters are patched in the desired sequence at the breakout module.
A jumper is used to define the filter type for each sub-unit for the mix unit of the main module.

The breakout module can be used without modification only in combination with the new version of the A-127 (pcb printing "Version 4").
Only the new version has the expansion connector available, that is required to connect the breakout module.
It's also possible to combine the breakout module with older versions of the A-127 (versions 1, 2 and 3) but in this case soldering is required to connect the breakout module to the main module (soldering 4 wires to each filter unit).

We will publish corresponding modification instructions as soon as the breakout module will be available."

You can still find my own A-127 DIY-expander blogposts via


The new Doepfer modules will be shown at #MusikMesse in the booth of their distributor Alex4 in hall 5.1, booth nr. C54

Update May 23 2014: " The A-127 BOM is already in production and should be available July 2014."

Doepfer Re-Designs Update

The 'old' A-166
Dual Logic Module
No exciting Doepfer announcements for the upcoming MusikMesse (The world's largest trade fair for musical instruments 12-15 March, Frankfurt/Germany) yet, but Dieter Doepfer did update the members of the Doepfer A-100 Usergroup today on a few upcoming module-plans and re-designs.

" So far there is no release date for the A-166-2 available the zero crossing comparator was also mentioned as part of the module.
The inquiries for such a module seem to be very poor.
But I will finish this module anyhow (just for myself) because I need such functions now and then (especially the flipflop)..."

The original
A-114 RingMod
Find more about the A-166-2 features in my blogpost from last November HERE

"...In addition we think about the redesign of some older modules.
Especially we think of new arrangements of some dual modules (Dual Ring Modulator A-114, Dual S&H A-148, Dual Trigger Delay A-162, Dual Slew Limiter A-170, Dual Trigger Modifier A-185 ...) as in many cases e.g. only a single ring modulator or a single Sample & Hold.

This will lead to some new combo modules (e.g. combination of S&H and VC slew limiter in one module) with a more value for money as you do not have to pay for unused second sub-units."

ADDAC210 Open Heart Surgery, Thoughts and FreqTalk Dreams

ADDAC210 Open Heart Surgery - Eurorack & Arduino Development Board
I'm still stoked about last weeks' ADDAC210 specifications announcement that i just had to write an extra blogpost about it.
At least 5 people already decided to pre-order this new Eurorack and Arduino Development Board, so the module will definitely be taken into production by ADDAC, a Portuguese company that has produced many more other innovative modules (100s Series!)over the last couple of years.

Although the idea is not completely new (see BeavisBoard), this is the first time that it is integrated in a 36HP wide Eurorack module with pre-mounted knobs, switches and mini-jacks.
Reading the comments about the ADDAC210 all over the web, the overall thought of most people seems to be "what can i do with it?"
The BeavisBoard-website has some nice examples that will also be interesting for synth-enthusiasts, but possibilities are almost limitless...

If you're a Eurorack fan, into synth DIY, and familiar with breadboards you instantly see this as an exciting and challenging module.
This must be the ultimate way to design, create and prototype your wildest synth ideas... and it will make bread-boarding so much easier!

The ADDAC210 comes with a 1 meter flat-cable and four 5.5cm. stands, so you can also keep it on your desk outside of your Eurorack while you are working on it.
The breadboards will be screwed to the front panel to allow "pre-patched" breadboards to be interchanged too. 

The knobs and the inputs on the bottom of the module will make designing new Eurorack synths/controllers feel very intuitive.
Now you can start experimenting, you will only have to get your hands on a (classic) cool (synth)-chips or other small electronics and then you can have so much fun with this... 
Expand your project on this breadboard by adding adding your favorite filter circuits and stuff... so exciting...
This module will bring Eurorack-patching to a micro-level with tiny jumper wires, resistors, diodes, microchips and more.
I'm already looking forward to the first creative online video examples...

A few random ideas:
Random spare parts
- experiment with your old chips that were always somewhere hidden on the bottom of your DIY-case
(maybe leftovers from other (old) synths, or old radio-parts)

- With an added Arduino shield/board there are multiple sequencing/ timing / mathemetical- related functions that would be possible... (and even sampling !)

- How cool would it be to install various sensors on it? Adding a light-sensor/photo-resistor can turn this into a theremin-like module... but also think of a pressure-, heat-, or... lets say a humidity-sensor or Anemometer (a device used for measuring wind speed (vid)? It might sound weird now, but who knows what voltages you can use and what effect it can have on sound...

- Try to build your own Brian May treble booster; a single medium-gain transistor with low-value caps on the input boost the treble part of the signal. The original used a BC182L transistor but the 2N5087 works just the same. This circuit is very close to the original Dallas Rangemaster. (via the BeavisAudio-site)

- My ultimate wet dream would be (re-)creating something like the FreqTalk (see below) or some kind of Flame Talking Synth-clone (and HERE) with the use of one or two Magnevation SpeakJet (or other) speech-chips.
The FreqTalk is based on an Arduino board and 2 SpeakJet chips and I have a feeling that the ADDAC210 will make a speech synthesis synth like this possible, and probably quite easy too IMO.

" Narrated introduction to the FreqTalk synthesizer."

Video 2: FreqTalk freestyle demo

" FreqTalk synth playing through AdrenaLinn effects.Cameo appearance by E-Mu PX-7 drum machine.
(c) 2010 Andy Hutson"

In the comments Andy writes:
"... the SpeakJets basically cover 3 octaves (B0 to B3), but since the tuning is integer-based, and musical tuning isn't, many of the notes are slightly sharp or flat, but it's close enough for techno, so to speak. The chips are worth getting...they're a lot of fun to play with in Arduino applications. Easy serial communications, minimal wiring required."
"... It took several weeks of evenings, but I didn't keep track of all the hours. Thankfully for the new model, most of the code was a direct cut-n-paste, and I just have to add code to drive the sequencers and LCD screen. Hope to have it done and new videos posted before the end of the year.
"... I don't see mass producing these anytime soon, but the thought has crossed my mind. If I find the time, I'll post news on this channel. Currently, I am working on a new model...same sounds, but better interface, with an LCD screen and built-in step sequencer... SpeakJet chips are basically triggered via serial messages, but in conjunction with an Arduino, you can wire them up to accept almost any kind of signal to trigger them."

Videos uploaded and comments by lamatronix

I understand that you do have to have a bit of knowledge about electronics and probably about Arduino programming, but this module is ideal for anyone who wants to start realizing their own Eurorack synth or controller.
Still a great module for enthusiastic beginners...
