Modular Synth - An All Doepfer Orchestral(ish) Patch by IsVisible

IsVisible uploaded an interesting new video to YouTube... enjoy!

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.

Ginko Synthese Flightcases

Ginko Synthese portable flightcase frontside 
Ginko Synthese, known from their recent successfully funded SampleSlicer project and their TTLFO, has been making modular cases for quite a while...

Now this Dutch company is thinking about making a small batch of portable flightcases (the white one with aluminium corners), maybe 10 or 20 pcs.
The final size is up to you!
The pictures are an indication of what it will look like (a case he made earlier).

The busboards are connected directly to the back of the case in this one, but if enough people are interested he will make internal mounting rails for them so there will be nothing visible on the outside.

Ginko Synthese portable flightcase backside
Specifications:
- 114HP width (may be different if people like)
- includes PSU and Doepfer busboards
- case depth will be around 11cm
- keeps your patches inside while lid is closed
- detachable lid
- 220V connection on side for standard eurostyle power cable

The price will be around €500,- ex VAT. (single sided rails).

Doepfer A-105 SSM 24 dB Low Pass Filter Demo by LesIndes

LesIndes uploaded a long demonstration of the Doepfer A-105 SSM LowPass Filter.

The A-105 is very similar to the A-122 that is made with a CEM chip. But in contrast to the A-122 the A-105 is made with the legendary SSM filter chip SSM2044.
This chip was used e.g. in these synthesizers: Korg Polysix, Korg Mono/Poly, Fairlight II, PPG Wave 2.2 und 2.3, Emu SP-1200, Siel DK600, Siel Opera 6. 
The first Prophets used the SSM2040 - the precedessor of the 2044 - that generates a very similar sound. 

The special feature of the 4 pole low pass SSM2044 is the patented so-called "true open loop design that delivers a characteristic fat sound not available from other devices" (extract from SSM2044 data sheet). 

The module features voltage controlled resonance and a sensitive audio input to obtain distortion - if desired. 
Regarding to the functions, controls and in/outputs the module are identical to the 24dB low pass filter A-122 that is built around a CEM chip, but the sound, the resonance behavior and the distortion behavior are completely different for both modules.

As the special circuit SSM2044 used in this module is no longer available the module has to be discontinued. Sale while stocks last !

" SSM filter chips were used in many great vintage synths in the synthesizers' hall of fame. such as the original SEQUENTIEL CIRCUITS PROPHET V, EMU E2, PPG WAVE 2 / 3. the filter chip is 2044.

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;

SiteTip: Equipboard

These last few weeks i have been trying out a 'new' music start-up called Equipboard.
The site mainly focuses on the question: What gear do my favorite music artists use?


" Equipboard is a community-built database of artists and the gear they use.
Launched in late 2013, this growing community of gear-obsessed music fans have already made the connection between 13,147 products and 4,480 artists – everything from Jimi Hendrix’s guitars and amps to Aphex Twin’s arsenal of electronics.
In addition to contributing, users can create their own equipment boards to share the gear they have or want, and participate in authentic conversations about their favorite artists and brands.

Artists and brands can claim or create a profile to add additional content and participate in conversations with fans.
Some of the brands already using Equipboard include: AIAIAI, Intellijel, Fab Filter, Lennar Digital, Bohemian Guitars."

I have tried it out now for almost a month and i like the idea of it.
The site certainly looks great, you can find a lot of info on the kits of known (and unknown) producers/artists but the list of instruments is still far from complete...
Luckily it is easy to add your own instruments, so i have put my full studio-setup up at http://equipboard.com/patchpierre.

I did not spend any time on uploading all my Eurorack modules, because i did that already on  ModularGrid, which does almost the same (but only modular synthesizers), but also mainly with user-generated data.
There's a nice (but still small) community that can interact/like/follow together, but there's not a lot activity (with me) yet... it could use some more contributors/members.

Check it out for yourself at:  http://equipboard.com

Doepfer A-110-4 Thru Zero Quadrature VCO Announced

Doepfer's latest module-announcement is the A-110-4 Thru Zero Quadrature VCO.
I do have to dig a bit deeper into this module before i completely understand it, but here is the text from the Doepfer website, where they will soon have audio examples and oscilloscope views available...

Doepfer A-110-4
Thru Zero Quadrature VCO
" The term "quadrature" means in this connection that the oscillator outputs sine and cosine waveforms simultaneously. 
The term "Thru-Zero" means that even "negative" frequencies are generated. 
This can be a bit of a misleading term as negative frequencies do not really exist. 
"Negative" means in this connection simply that the sine/cosine waves will stop when the linear control voltage reaches 0V and continue with the opposite direction as the linear control voltage becomes negative and vice versa.

The module has two control sections: linear and a exponential. 
The exponential section consists of the XTune control, the 1V/Oct input and the XFM input with the corresponding attenuator XFM. 
The exponential control voltage is the sum of these three voltages. 
The linear section consists of the LTune control and the LFM input with the corresponding attenuator LFM. 
The linear control voltage is the sum of these two voltages. 
A dual color LED is used to display the polarity of the linear control voltage (green = positive, red = negative). 
The resultion pitch of the sine/cosine outputs is determined by the resulting control voltages of both sections. The linear section is used to control the pitch in a linear manner. 

When the LTune control (LTune means Linear Tune) is fully CW the module works like a normal Quadrature VCO (e.g. like the A-143-9) and the LED lights green. 
The pitch is then controlled by the exponential section with the manual Tune control and the exponential frequency control inputs 1V/Oct and XFM. 1V/Oct is used to control the pitch by a 1V/Oct CV source (e.g. sequencer or Midi/USB-to-CV interface). 
XFM is used to apply an exponential frequency modulation with adjustable depth (e.g. from an LFO or another VCO). 
As the LTune control is turned counterclockwise starting from the fully CW position the frequency is lowered in a linear manner until the sine/cosine waves stop near the center position of LTune (provided that no LFM signal is present). 
As the LTune control is moved from the center towards the CCW position the waves start again but into reverse direction and the LED turns red. 
When the fully CCW position of LTune is reached the module works again like a normal Quadrature VCO. 

But much more exciting is the usage of the LFM input to modify the linear control voltage by an external control voltage (typically another VCO). 
Linear modulation by another oscillator using the thru zero feature generates audio spectra than cannot be obtained from an oscillator without the thru zero function. 
The reason is that a "normal" VCO will simply stop as the linear control voltage becomes zero or negative. 
But a thru zero VCO will start again with "negative" frequencies as the the linear control voltage becomes negative.

The main advantage of the A-110-4 compared to other Thru Zero VCOs is that the design used a sine/cosine core. The sine/cosine waves are not derived from other waveforms (e.g. sawtooth or triangle) by means of waveshaping. 
Rather the sine and cosine waves are the core of the VCO which results in very pure waves with a minimum of distortion and overtones." 

The A-110-4 is planned for early 2015, price ~ Euro 120.00

Doepfer A-160-2 Clock Divider II Announced

Doepfer announced a few new modules modules this week.
Starting with this one:

The A-160-2 Clock Divider II is an enhanced version of the standard clock divider A-160.
The 4HP wide module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses.
Doepfer A-160-2
The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface.
At the outputs, you have access to three sets of seven different sub-divided clock signals, from half
the clock frequency down to 1/128.
The low/high levels of the output signals are 0V and about +10V.
The A-160-2 also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

These are the most important features of the module:

- Three different sets of dividing factors, selected by a three-position switch at the front panel: power of two: 2, 4, 8, 16, 32, 64, 128
prime numbers: 2, 3, 5, 7, 11, 13, 17
integer: 2, 3, 4, 5, 6, 7, 8
- Two output modes, selected by a two-position switch at the front panel:
- Gate mode: outputs act like the outputs of typical binary dividers
- Trigger mode: in this mode the outputs are AND-wired with the clock signal (i.e. the clock pulsewidth affects the pulsewidth of the outputs)
- Clock edge type selected by a jumper on the pc board:
positive: the rising edge of the clock signal triggers the state change of the outputs
negative: the falling edge of the clock signal triggers the state change of the outputs
- Reset behaviour by two jumpers on the pc board:
level triggered: the level at the Reset input triggers the Reset
edge triggered: the edge of the signal at the Reset input triggers the Reset
positive: a high level (> 2.5V) or the rising edge at the Reset input triggers the Reset
negative: a low level (< 1 V) or the falling edge at the Reset input triggers the Reset
- Output polarity selected by a jumper on the pc board:
positive: non-inverted outputs
negative: all seven outputs are inverted

The module is planned for early 2015, price ~ Euro 100.00

Steffcorp ARP2600 Eurorack modules

VCF 2612
Arplifier
Steffcorp from Sweden is the next new Eurorack manufacturer on my list.

After passionately working with synthesizers for over 20 years, doing both music and a lot of sound-design, Rickard Steffensen started a journey 2 years ago recreating his favorite synthesizer of all time – the legendary ARP 2600.
The result of this quest is the first batch of 4 Eurorack modules that Steffcorp released this month;

The Oscillarp is a eurorack-clone of the 4027-1 VCO used in the ARP 2600.
The VCF 2612 is a clone of the 4012 VCF used in the ARP 2600.
The Envelarp is a eurorack-clone of the 4020 ADSR/AR used in the ARP 2600.
,and the Arplifier VCA is a eurorack-clone of the 4019 VCA used in the ARP 2600.

Envelarp
Oscillarp
Rickard is now working hard on getting a full voice of 2600 modules out the door, followed by other even older designs that deserve to be revived.

I'm looking forward to the first sound-examples...

Animodule TikTok Clock Multiplier and Divider Overview by DivKid

Animodule
TikTok
DivKid uploaded an overview video about the Animodule TikTok.

The TikTok is a 4HP Clock Divider/Multiplier that calculates divisions and multiplications of:
*//2 , *//3 , *//4 , *//5 ,and *//6

There is a Clk Input and a Reset Input.
Both are buffered with an opamp based comparator circuit.
They are looking for approximately +1.1V on a rising edge.
This means that you are not constrained to gate (pulse) signals to trigger them.

The Reset input resets your divisions clock counter to 1
There is a switch to select Mathematical or Musical divisions.
The Multiplication Outputs 25MS Trigger pulses.
The Division Outputs are on as long as your Clock source.

- Avg Current draw:
40 mA / -9 mA
- Peak Current Draw:
80 mA / -17 mA
Width = 4HP
Depth = 38mm

Modular Wild Presents - Synthrotek Triple Response VCA

Raul Pena just released a new Modular Wild video about the Synthrotek Dual Triple Response VCA.

"The Synthrotek Triple Response Dual VCA uses high quality op amps to give you the sound quality you are looking for in affordable kits and completed units.
This VCA has three different response curves per channel: 2 Exponential and 1 Linear.
The amplitude of EX2 (switch at right position) can be slightly attenuated via 1 trimmer pot per channel on the PCB.
This allows for 3 different curves per channel. EX2 has a slightly more exponential curve than EX1. This VCA operates at 0-5V; a 5V CV input will give you 10V peak to peak audio output.
Use over 5V if you want a super ballsy, loud VCA!
The module is intended for AC and audio use only (DC coupling will not function properly).

Features include:
- ~10V peak to peak output with a +5 DC CV input
- 2 exponential and 1 linear response per channel
- Channel 2 is normalled to channel 1
- Compact 4HP sized module
- Kits, complete and PCB/panel combos
- High Quality Op Amps
- Module depth: 1 7/8 inches (4.7 cm)
- Max current draw: 1mA on -12V rail, 9mA on +12V rail "

Noodlebar 2-Year Anniversary: NoodleFest!

Last weekend,Saturday October 18th, i visited the 2-year anniversary of the Noodlebar NoodleFest in Roodkapje / Rotterdam / the Netherlands
On this special evening a selection of artists who have ever played at Noodlebar in the past 2 years, showed their modular skills in two different rooms.
The main key of Noodlebar remains that there is no computer involved...

" In 2012 Dennis Verschoor AKA Mono-Poly decided it was time for a monthly evening devoted to modular synthesizers.
Luckily he found in BAR the place who were open to the more experimental side of music where he along with Falafelbiels put down the first night.
In 2013 Noodlebar made the switch from BAR to Roodkapje where it got the space to grow to where it is today.

Falafel Biels
As the scene is so niche based, the name Noodlebar spread fairly quickly and there were plenty of artists who were only too eager to come and play.
Foreign artists who happen to
be in the neighborhood also added to the international allure."

Roodkapje is a very nice venue for these kinds of gatherings and i was surprised about how many people were attending this party, mainly men in their 40s ;-)
The party was well organised and each performer had about 20 minutes time to show off their various modular skills.
I spent a lot of time walking from room to room so i could get a short impression of most performing acts.
I sadly cannot review everything that i have seen, because there were around 15 acts(!) performing...

Falafelbiels kicked off in the small room with an exprimental set, followed by an impressive droneset by Kapi Kapnobatai...
A few other highlights in the small room (for me) were Geritz & Kafka, who brought their (heavily effected) guitar onto the stage, and Zen.Se from Belgium who only brought his EMS Synthi AKS and impressed everyone.
After KANG (the only female performer) finished in the small room with an extremely expressive noise-set at around 1AM everyone gathered in the big room to listen to the last acts in the main room until 4PM.

(Ji Youn) KANG
Acts worth mentioning from the big room were Dennis Verschoor AKA Mono-Poly on his large Serge modular, Colloid with Jan Willem from Ginko Synthese, and Sierra Romeo & Fraknoise who performed with a Theremin on stage and Osc1899.
The later it got, the more beats were heard too, allowing the audience to actually dance a little.
Das Ding, Ruistuin and Zenn did some more melodic and danceable sets, followed up by the closing performance from Rumatov.

Dennis Verschoor AKA Mono-Poly on his Serge Modular
Also 'performing' on the side throughout the whole night was the newest member of Noodlebar Harry Plotter, an 'artist' who shapes the sequences of a synthesizer and a plotter on paper.
More info on Facebook

The whole event in the big room was streamed live over the internet (powered by Grooveline) and different sets (from both rooms?) will be published in the near future via Vimeo and/or other channels.
Just keep an eye on my Twitterfeed, i will probably add some links to this blogpost at a later time...

Zenn
The Noodlebar parties at Roodkapje are organised once a month (although i did hear a rumour that
they might have to move to another location next year) and this was the first time I visited.
I can recommend this event to anyone who is interested in modular synthesis, noise and wants to meet the Dutch modular/Eurorack -scene.
The next Noodlebar party will be somewhere next month... (update will follow soon)

I will probably wear a PatchPierre nametag/badge a next time, so please take some time to talk to me whenever you see me there a next time... due to my slightly autistic limitations i am not the one who will easily start a conversation, but i'm always interested in hearing your stories and/or promoting your modular/Eurorack related stuff on my blog. (yes, that was me in my black smiley t-shirt...)

Random Video: Chaotic Harmony with the Intellijel µScale by Steve Castellano

Steve Castellano ‏uploaded a nice video showing a fun way to incorporate an Intellijel µScale into a modular patch with MakeNoise Maths and René...

Video: Chaotic harmony with the Intellijel µScale

"Here's a quick and easy way to to add quasi-chaotic harmonic accompaniment to a sequence with the Intellijel µScale and whatever spare oscillators you have lying around.
I've kept the patch pretty simple for the purposes of the demo:
Make Noise Rene → Intellijel Dixie II
Intellijel µScale → Intellijel Dixie II & Make Noise STO
Make Noise Maths → µScale CV in & shift (via Doepfer A-148 Dual S/H)
Dixies & STO → Intellijel Korgasmatron
Korgasmatron → Pittsburgh Dual Index
Intellijel Dual ADSR → Korgasmatron & Dual Index
A very basic subtractive setup, in other words."
