Big A-100 Book by Andreas Krebs Delayed

Sad news for some of the non-German-speaking A-100 fans;

The original German version
of the big A-100 book by Andreas Krebs
Das Grosse Buch zum Doepfer A-100 Modular-Synthesizer, the German A-100 by Andreas Krebs that was published half a year ago (also check my earlier BookTips) will probably not be available this year yet.
I recently contacted him about a possible release-date of the (pre-announced) English version, but he replied that the project is delayed.

He wrote: " There had been plans to release the book end of this year. However, there have been some big delays in this project due to personal reasons (currently we’re moving from Munich to the countryside).
I hope to be able to put some more efforts on the english version as soon as we have moved and everything is “in its place” again."

I hope his situation will improve soon...

The German version is still available;
Price: Euro 29,90 € plus shipping
Find more info and ordering details at: http://www.ideenhase.de/html/doepferbuch.html
German version is also available via Doepfer

Filters VII: A-106-1 Xtreme Lowpass/Highpass Filter

The Doepfer A-106-1 Xtreme Filter was built as a kind of Korg MS20 filter clone.
The famous original MS20 included two filters: a 12 dB lowpass and a 6dB high pass filter connected in series both with a very special design.
On the A-106 product page Doepfer writes: " The A-106-1 is definitely not the right choice for "moogish" and "civilized" sounds but for extreme, exceptional and experimental sounds - this is why we call the module "X-Filter"... "

Doepfer found a way to use the same circuit simultaneously as lowpass and highpass for 2 different audio signals (a bit similar to the A-101-1 Steiner Vactrol filter that has even different audio inputs available, but with the special MS20 circuit).
For this two separate audio inputs for lowpass(LP) and highpass (HP) with separate level controls are available.
The sockets are normalled, so the signal applied to the LP input is available for the HP input too provided that no plug is inserted into the HP input socket.

The level control of the HP input is realized as a polarized input. This means that the signal can be added with the same polarity (+ range) or opposite polarity (- range) compared to the LP input.
This feature enables notch (+) and bandpass (-) filter functions too.

A lot of audio-examples can be found HERE
and on Andreas Krebs' blog

As you will hear in the demo's this is a very nice sounding filter with a distinctive sound.
It can sound very squelchy and dirty, and still also quite smooth...
If you are looking for a do-it-all filter, this might be the one you are looking for.
It is not my favorite filter, but i still rate it at 7/10...

Booktip XI - Das grosse Buch zum A-100 Modular Synthesizer (in German Language)

A very interesting book by Andreas Krebs is almost out... although it is (still) only available in the German language.
The author has been working with analog (and other) synthesizers for around 30 years and has already written and maintained a pretty impressive blog.
His " Big Book to the Doepfer A-100 Modular-Synthesizer" will be available at the end of 2011/Now

In 320 pages he systematically goes through the most interesting modules in full detail and suggests unusual patches from his 'trick-book'
The book is illustrated with over 400 images, and a good read for not just Doepfer enthousiasts, it's a very nice book for analog synth enthousiasts too... 
It explains basic and some more difficult analog synth theory in a clear way.


Update 30/5.2025:

The book is out of print, but the author kindly offers it for free download:
