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 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
- 104 or 114HP width
- 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

Updated November 3, 2014
You can still order for this batch.
They are available in two sizes:
104HPx6U = €320,-
114HPx9U = €500,-
They come including PSU and busboards.
The color is white/grey and have a subtile gynkosynthese logo engraved in the lid.
The power connection is on the side so you can use it laying flat or standing vertical.
Check the Ginko Synthese Portable Cases product-page for more info on how to order:

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.

- 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

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:

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

Update Nov 27th 2014:
" we also think about a A-161-2 which is independent from the A-160 (i.e. own clock and reset). Details are not yet available, except one thing: switchable between gate and trigger mode, in trigger mode the outputs are "gated" with the incoming clock signal. 
And we are working also on a clock multiplier module (A-160-3 ?). 
But the release dates, prices and detailed features for these new modules are not yet available."

Steffcorp ARP2600 Eurorack modules

VCF 2612
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.

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...

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

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...

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."

Modular Theremin Explorations by Wellurban

I wrote earlier about the possibilities of the A-178 Theremin Control Voltage Source outside the 'recreating a Theremin sound' spectrum.

The voltages out of the A-178 can be used for controlling any voltage controlled parameter of your Eurorack, like pitch or pulsewidth, loudness, panning, filter frequency or resonance from all of the filter modules, phasing, frequency shifting, envelope parameters and tempo, to name just a few.

YouTube user Wellurban created a video with some great examples...

AJH Synth MiniMod Eurorack Modules

MiniMod vintage
transistor core VCO
Another new modular synth company, AJHSynth is headed up by Allan "J" Hall, who has been involved with synths, electronics and music for more years than he cares to remember.
He started by building a guitar fuzz box at the tender age of 12 and an interest in synthesisers and electronic music soon followed, fuelled by an unhealthy overexposure to early Tangerine Dream, Pink Floyd, Vangelis and Kitaro.

For the last 15 years he has been building and modding synth systems both for himself and other electronic musicians, as well as spending some time as a semi-pro musician playing keyboards in several rock and tribute bands.
Allan spent five years as a service technician repairing and modifying Moog, Arp, Korg, Roland and other analogue synthesisers along with some Pro Audio design work, previous to this he spent two years designing and building "boutique" valve (tube) guitar amplifiers.

MiniMod countour
generators (2 x ADS)
AJHSynth are based near Bournemouth on the South coast of England, where this small but enthusiastic bunch of synth. heads now indulge their passion for all things modular.

The MiniMOD Eurorack system aims to replicate the sound of the vintage Moog Model D as closely as possible, so they used exactly the same internal circuitry and every module runs at the same internal signal and control voltage levels as the original.

Their quest was to bring the unbeatable fatness and legendary sounds of this classic synthesizer to the 3U Modular world and have separated the synth into five modules, comprising:
MiniMod transistor ladder filter
VCOVCFVCADual Contour, and Glide + Noise, which can be easily integrated into an existing Eurorack system or, with the addition of a case and power supply, it becomes a self contained stand alone synthesizer.

Click here for an overview of the MiniMod.

glide + noise
The MiniMod is based on the circuitry of most desirable Model D of all, the very early R A Moog Mk1 model with its unique and sweet sounding VCO design, the core of which uses discrete transistors only, with no integrated circuits.
We have also based the transistor ladder VCF on the early design, which uses fully matched transistors throughout.
Less than 300 Mk1 Model D’s were built with this very early VCO design out of a total of around 17,000 which were produced between 1970 and 1981.

The Minimod has been more than 18 months in development, thousands of hours have been spent analysing the original Model D using both real world measurement and computer based Spice circuit simulation programs, they carefully selected components and built many prototypes before they were happy that we had done justice to the original sound and circuit behavior.
MiniMod discrete
cascaded VCA

MiniMod Eurorack modules comprise separate VCO, VCF, VCA, Dual Contour and Glide/Noise for maximum flexibility so that they can be easily integrated into a larger Eurorack format Modular synthesizer to tap into the endless control and expansion possibilities – they removed all of the control limitations of the “closed system” of the original Model D synthesizer so that the sounds that you can now create are limited only by your imagination and the other modules that you add to your system. All of the modules can be used independently in your existing Eurorack system.

 A full MiniMod system would comprise 3 x VCO, 1 x VCF, 1x VCA, 1 x Dual Contour, 1 x Glide-Noise and this will take up exactly 84hp of Eurorack space, so that it will fit into 3U of rack space with a suitable Eurorack frame and power supply (not supplied)
Just add a Midi/CV converter and keyboard for a fully functional BIG and FAT monophonic synthesizer.

offers 3 manual gates, and some kind of Gate-pattern recorder/looper.
This module with big arcade-style buttons looks pretty amazing, and will come in very handy if you want to program drum-patterns that are not quantized.

The Qu-Bit team recently explained in an episode of The Distilery Podcast that this is not the final Tri-ger version yet, and that there will be another prototype produced before a finished module will reach the markets.
A new version will probably include a few quantize options and other functions, the arcade-style buttons will probably stay...

More info will be added here when available

Entrospec Iungo CV-to-MIDI Eurorack Module

Another new Eurorack manufacturer, now from Bristol, introducing a CV-to-MIDI converter with a twist...

Entrospec Iungo
The Entrospec Iungo is designed to bridge the worlds of modular synthesizers and MIDI controlled instruments.
This module lets you create both monophonic and polyphonic sequences to play your MIDI gear, all controlled by your cv and gate generating modular system.

The Iungo is in essence a CV to MIDI converter, but instead of acting as a direct translator, this module gives you voltage control of the MIDI data stored in banks and patches.
It has the following features:

- Stored MIDI data accessed via cv and gate inputs.
- Banks will store up to 16 notes and rests. Each note can have an independent MIDI channel.
- Each bank can also store 1 program change message.
- 5 memory locations to store patches
- “Chord” mode outputs all notes in a bank simultaneously when triggered.
- “Seq” mode outputs each note in a bank consecutively upon receiving a gate s- ignal.
- “Poly Seq” mode runs all 5 banks in sequencer mode simultaneously.
- The length of each bank is independent, allowing for more complex sequences to be produced.
- Chords and sequences can be transposed via the MIDI input.
- Velocity of MIDI data is determined by the amplitude of the gate signal.
- MIDI input and output via 2.5mm stereo jack to 5 pin DIN cables. The same format adopted by iOS devices.
- Panel size 6HP
- Module depth 41mm
- Maximum current consumption 59mA on +12V "

Price: £139.99 + postage, included with each module are two 2.5mm stereo to 5 pin DIN MIDI cables.

A few demos highlight some of the functionality that Iungo provides:

Video 1: Iungo from Entrospec

" A short demo that highlights some of the functionality that Iungo provides. Integrating MIDI controlled instruments with modular synthesizers by allowing voltage control of MIDI data.
A little about the patches:
1 - CV and Gate inputs from Make Noise Rene
2 - Gate from Shuffling Clock Multiplier, voltage offset scrolls through the 5 sequences, then random CV input from noise/sample & hold through an offset generator.
3 - Gate from Shuffling Clock Multiplier "

Video 2: Entrospec Iungo and Hexinverter Midi2cv

" Iungo in polyphonic sequencer mode being used to sequence 3 vco's via a Hexinverter midi2cv.
The vco's are out of shot, the cv outputs of the midi2cv control the pitch of each vco, and the gates trigger envelopes, 2 from the Make Noise Maths and a third out of shot.
The envelopes and vco outputs are patched to 3 channels of a Make Noise QMMG.

Midi2cv is in Poly 4 mode, so each cv and gate pair is addressed with a different midi channel. Note sequences have been stored in the Iungo beforehand, and the parts are brought in by unmuting them in the mute menu.
Iungo is clocked from a 4ms SCM. The pulsewidth of the triggers are increased towards the end, increasing the width of the gates going to the envelopes."

Dave Smith Instruments DSM01 Curtis Filter

Known for their great in-depth reviews, SonicState/Soniclab has published another long video demonstrating Dave Smith Instruments' latest product, the Dave Smith Modular DSM01 Curtis Filter, that was released earlier this year.

Dave Smith Modular
" The module takes its name from the original filter chip designed by the late Doug Curtis and provides both a switchable 2/4-pole low-pass filter and a VCA.
The Curtis filter is an integral part of the sound of many synthesizers created by Dave Smith, including the classic Sequential Circuits Prophet-5 and Pro-One, and more recent instruments such as the Evolver, Mopho, Prophet ?08, and Prophet 12.

The “Curtis sound,” which is often described as saturated, brash, and powerful, was fundamental to not only Smith’s synthesizers, but also to such highly-regarded instruments as the Oberheim Xpander, Rhodes Chroma and Polaris, PPG Wave, Korg MonoPoly, Waldorf Wave, Elka Synthex, and many others.
“We wanted to make the classic Curtis filter sound, which I’ve always found very versatile and expressive, readily available to modular users,” said Smith. 
“Adding the DSM01 to a modular system is an easy way to give it the sonic edge that people typically associate with a vintage Sequential synth. 
But it’s also a big part of the sound of my current synths such as the Prophet 12.”

The module is a standard 8HP wide, Eurorack-format device with interconnections made using 3.5 mm phone jacks. 
A set of inputs and parameters allows voltage control of filter frequency and resonance. 
Filter slope is selectable between -12 dB and -24 dB. 
The module also provides its own VCA and features two separate outputs for the filter—one pre-VCA and the other, post-VCA. 
A unique feature of the filter is a Boost function that introduces harmonic distortion into the signal for more aggressive coloration."

" The first module from Dave Smith is the classic Curtis Filter. In 8HP it also has a VCA to further expand the features available in such a small module."

Dtronics Digidrum 80s Style Eurorack Drum Module

Dtronics uploaded a video of their latest Eurorack module, the Digidrum.
(NOT the most original name btw...)
Here shown are 8 identical modules, with each of them carrying with a different (Linn) drum sample.
I'm impressed of how authentic it sounds, i hope to add more info soon...

Video: Dtronics Digidrum, 80's style eurorack drum module

" Dtronics Digidrum, 80's style eurorack drum module.
With a 80's soundset ( 8 sounds ). the samples are recorded with an Oberheim Prommer to get the right sound.

The unit also accepts home made sounds ( you have to put them in an serial eeprom or you can buy complete soundsets)
or you can place one original 4K eprom with your Linndrum / DMX sound.

-accepts original LINN / DMX etc eproms (2732 / 4K)
-accepts serial eeprom with custom sounds
-Sound can be tuned to the extreme (to get thos dirty strange sounds)
-only 6HP wide

More info soon here and on the Dtronics website."

Random Video: Modular Carousel by diafragma365

I found this one on YouTube....

Video: Modular Carousel by diafragma365

" An unprocessed recording of a rather simple but musical patch on my eurorack.
It started as a test of the Scale Select Mode of the Intellijel μScale II, with the Make Noise Pressure Points & Brains used to step through a simple sequence of eight chords.

A Make Noise Maths in combination with a Doepfer S&H were used as a random arpeggiator for the organ-like sound from the Synthesis Technology Morphing Terrarium, going through the E440 VCF to the Make Noise Echophon and Erbe-Verb in order to create some room around the sound.

The rhythm for the “organ” arpeggios is somehow randomized by applying a randomized Ginkosynthese TTLFO multiplication function to a tempo from the ALM Pamela’s Workout, the basic tempo engine for this patch.

While the bass kick sound is a straight 4/4, the hi hat is triggered by a patch on the 4MS QCD, partially controlled per measure by the Make Noise Pressure Points and Brains.

This patch was a nice experiment for me to introduce some randomness in a limited musical framework of eight chords and the sound reminds me of the organ going mad with its short notes on the carousel on the fair where I used to go as a child."

Monome Meadowphysics

Monome just released the Meadowphysics rhizomatic cascading counter, a grid-enabled module for the eurorack platform.

Monome Meadowphysics
" Meadowphysics facilitates the exploration of polyrhythms and rule-based sequencing, producing a
wide range of emergent patterns.
A monome grid is plugged into the front panel of the module, serving as a complete interface.
Tthe procedure continues running when the grid is disconnected, facilitating both live performance and precomposed playback of generative systems.

As the second module in the grid-based eurorack series, this module highlights the ability to swap the grid between modules rapidly, patching the usb cable much like a 3.5mm cable.
This module can be used in conjunction with white whale using a single grid gracefully.
The foundation of meadowphysics is an incoming clock which can be internal or external.
Seven additional counters can be cross-assigned with this clock to count down an assignable number of counts, which is the primary interface on the grid. when a counter reaches zero, the corresponding output is triggered on the panel.
Given a flexible assignment method, very complicated long-form mutating polyrhythms can be created intuitively.

In addition a series of “rules” can be applied at the zero count of each counter.
The count length can be reassigned– incremented/decremented, randomized, reset to last value, etc. a counter can have a rule assigned to change another counter’s behavior. In this way long evolving patterns emerge.
Very simple falling rhythms can also be accomplished in a very straightforward manner.
A standard subdivided counter runs as a default behavior.
Configurations are preset-able and savable to flash for later recall and instant resume on power-up."

Medic Modules Cranial Saw - Advanced VCO / SUB Eurorack Module Demo by Rezfilter

Medic Modules Cranial Saw Eurorack Module
rezfilter made a nice video demonstrating the features of the 38HP wide Medic Modules Cranial Saw.
The Cranial Saw is a dual VCO
with Glide, Sync, Sub Oscillator, Pulse Width Modulation, Mixer and Cross Modulator.

" It features two discrete component VCOs based on early 1970s circuits so they sound very vintage and are full of character.

The dual VCO performs best in mid to low range, and combined with the Sub-Osc, produces huge, powerful sounds.
The main pitch CV input goes through a Glide / portamento circuit.
There are modulation CV inputs with attenuators. Also, VCO2 has its own CV Mod input.
Each VCO has a Pulse Width slider and PWM CV input sockets.
The VCOs also have Sync.
Cross modulation is possible by taking the output of say VCO1 and patching this to VCO2’s Mod CV input.
The built in mixer allows the two VCOs and the Sub-Osc to be mixed via their own attenuators.
The mixer has its own audio output of course, but the VCOs and Sub-Osc also have pre-mixer, fixed level individual outputs.
The two VCOs each can be switched between Saw or Square waveforms.

VCO1 can be set to ‘Freerun’.
This means it will not track the incoming pitch CV.
VCO1 can be disconnected from the Glide circuit.
Features such as Freerun, and the Glide disconnect of VCO1, as well as individual Mod CV for VCO2, allow a great range of sounds and weird effects to be produced when cross mod is patched, or Sync used.
A lot of thought has been put into all this. Please take a look at the videos on Analogue Solutions web site and YouTube channel for examples. The idea is to allow production of a wide range of VCO sound effects with the minimum amount of patched, though, of course, patching can be done.
All sliders incorporate a LED in their shafts. The Tune slider will flash in accordance to the pitch of VCO1."
