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.

The Rest: Alesis MMT-8 Sequencer

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 …

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.

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 ste…

MusikMesse 2014 Alex4 Booth with Dieter Doepfer

Once again, SonicState has made a nice video from the MusikMesse booth of European Distributor of analog synths and Eurorack modules Alex4.

The Alex4 Distribution booth with the big tagline " like Synths?" included MFB, KOMA, Doepfer, and Meeblip anodes, amongst other smaller (European) brands.

The SonicState booth-tours are almost an annual ritual, often with owner Andreas Schneider (from SchneidersBuero /SchneidersLaden) showing the whole booth and some of the new goodies...
This time Dieter Doepfer shows the new stuff, focussing on the Dark Flow, the stand-alone version of the A-157 Trigger Sequencer (Mini Schaltwerk) and some of the OEM/DIY products.

SiteTip: Modular Sub-Reddit

In case you didn't know already:

The Modular Sub-Reddit is an extremely valuable source of all kinds of (Eurorack and other) modular news, videos, tips and tricks...
Besides that it is also a nice discussion platform that can always use more participants.

Find it at

The community doesn't seem very talkative so far (which is strange for modular lovers), so please subscribe, vote articles up or down, join the discussions and add your own links...

Thank you in advance for your help and input!

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:
Video: Epoch Modular 'Benjolin' with Doepfer A-143-9 and A-135-1
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.
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…

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.

" 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 t…

Doepfer Re-Designs Update

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)..."

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 modulato…

ADDAC210 Open Heart Surgery, Thoughts and FreqTalk Dreams

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 c…
