Doepfer A-106-5 12dB SEM Filter Special Edition

Temporarily a special edition of the Doepfer A-106-5 12dB SEM Filter is available. It is equipped with a stylish Oberheim-style cream-coloured anodized front panel and black knobs.

A-106-5 SEM
Filter
Special Edition
Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM
module.
The filter is equipped with a band pass output and a combined low/notch/high pass output. 
For this output a control knob defines the relation between low and high pass signal. 
If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. 
The module does not feature self oscillation in contrast to most of the other filters of the A-100 system. 
The module generates a distorted audio signal if the level control is set to about 50% (i.e. center position) or more with A-100 standard signals like VCOs.

Inputs: Audio In, CV1 In without attenuator, CV2 In with Polarizer
Outputs: Bandpass Out, Low/Highpass Mix-Out
Controls: Audio Attenuator, CV2 Polarizer, Frequency, Resonance, LP/HP Mix

Doepfer A-106-5 12dB SEM Filter Tutorial Videos by Raul Pena

While I was gone, Raul Pena kept on making new A-100 video tutorials.
Here's the next series (now presented here as a playlist instead of weekly updating a blogpost), showing you all the ins and outs of the A-106-5 SEM Filter.

Analogue Solutions Telemark Multimode Filter

Analogue Solutions just released their Telemark Multimode Filter module, a eurorack module based on the Telemark multimode filter.

The Telemark multimode filter module is based on the filter of the legendary Telemark semi-modular synthesizer.
It's routes lie in the original 1970s Oberheim SEM, though it has developed a character of its own.
The filter is a 12db/Octave multimode type. Multimode means there are more than one type of filter output.
There are in fact four: low pass, band pass, high pass and notch filter.
Additionally, notch filter can be varied for an even wider range of sounds.
Use of Gain and Q allow for even wider possibilities.
No special knowledge is required to use this filter. Just plug your audio in the left, and your audio out on the right.
Optionally (and recommended!) patch a control voltage in to give the sound movement.

KEY FEATURES OF TMF
- Pure analogue circuitry.
- Telemark filter
- 4 filter types- Low, High, Band, Notch
- Resonance (Q) boost feature
- Slim design
- Spun metal knob caps

DivKid made another great video demonstrating the module;

Doepfer A-106-5 Demo by Icaro Ferre

This one popped up on Vimeo a few weeks ago.

In a short video Icaro Ferre shows what the A-106-5 12db multimode SEM Filter module can do in multiple modes, and with different resonance settings...

I have this module too, and I like it a lot.
The only thing i miss in this filter module is an extra CV input to control the resonance, just like the A-121 Multimode Filter or the other Oberheim filter, the A-122 24 dB Lowpass filter VCF3 have.

Random Video: Noodling on the Doepfer A100 Modular

I found this nice experimental video on YouTube, that only uses a few A-100 modules.
Not very spectacular, but impressive-sounding nevertheless.
