Video: Modular Synth - An All Doepfer Orchestral (ish) Patch
" Here's a patch I filmed about two years ago. Made with all Doepfer modules. Some patch notes: The A-143-4 Quad VCLFO/VCO is triggering the gate/envelopes of the A-143-2 Quad ADSR, clocking the random voltages from the A-149-1, providing cv for the two filters (A-106-1 Xtreme and A124 Wasp) The A-143-4 is in turn being modulated by two LFO's, A-143-9 and A-146. The two voices are then passed through a channel each of a Tapco 4400 Dual Spring Reverb. www.isvisible.co.uk"
This next video was uploaded to YouTube yesterday by Swan Messiah, 'Creator of the Doom Drone Experimental Metal', who recently got into Eurorack modular synthesis.
Here's his first experiment... a spacey tribute to Yuri Gagarin.

" Here we have the Doepfer A-143-4 Quad VC/LFO/VCO triggering the A-149-1 Random Voltages. The A-143-4 is also triggering the A-143-2 Quad ADSR along with providing a little cv to the A-110 VCO's.
All in all with a little filtering courtesy of the A-106-1 Xtreme Filter (Korg MS-20 inspired) and the A-124 Wasp (erm... a Wasp clone) it sounds a bit orchestral, in an abstract kinda way anyway.
Both line outs from the modular (bassier / brassier low end and plucked / reedish higher end) are going directly into a lovely old Tapco 4400 Dual Reverberation System then to my mixing desk where the audio is taken from."
Raul Pena is back with a new video tutorial series, this time all about the A-106-1 Xtreme Filter.
Here are the first two, of four...
Video 1: Doepfer A106-1 Xtreme Filter Basics
" A brief description of the features and functions of the Doepfer A106-1 Xtreme filter.
This filter is similar to the filter in the Korg MS20 but has its own unique character. Sound and Video by Raul Pena."
Video 2: Doepfer A1061 Xtreme Lowpass/Highpass Filter Audio Demonstration
"A look at an audio demonstration of the basic features of the Doepfer A106-1 Xtreme Lowpass/Highpass Filter. Sound and Video by Raul Pena."
Video 3: Doepfer A106-1 Xtreme Lowpass/Highpass Filter Modulation and Resonance Part One
" Audio Demonstration of Modulation and using the resonance insert of the Doepfer A106-1 Xtreme Lowpass/Highpass Filter. Sound and Video by Raul Pena."
Video 4: Doepfer A106 Xtreme Lowpass/Highpass Filter Modulation and Resonance Part Two
" Part Two of an Audio Demonstration of Modulation and using the resonance insert of the Doepfer A106-1 Xtreme Lowpass/Highpass Filter. Sound and Video by Raul Pena."
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.
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...
