DIY Eurorack MIDI-to-CV Converter by Stereoping

Today i discovered Stereoping and its interesting line of products.

Stereoping was founded by Gregor Zoll.
Since his graduate to a graphics designer he is selfemployed in 3D-computeranimation, programming and development of computergames.
As a sideline he always made lots of music and repaired, altered and – in the end – developed lots of musical equipment like drumcomputers and synthesizers.
Stereoping MIDI-to-CV
As his ideas got more concrete and his developments got more professional through the years, he started a business in 2013 for the development and worldwide shipping of innovative diy-assembly kits for musical devices.

If this business will develop as he hopes, his goal will be to offer complete out-of-the-box products in some years...

Stereoping produces 'DIY assembly kits for making magical music' and will be opening a webshop in early 2014, where he will be selling some of the products shown on their site.
Some modules will also be available as a DIY-kit...
They also have a special Eurorack section on their site with interesting stuff.

The latest product is this Eurorack MIDI CV Interface, a basic MIDI-to-CV converter which is really not that innovative, but still a good piece of work IMO.
I like the plain and simple design of the panels, and I'm looking forward to seeing more modules coming from this new company.

Video: Demo for my DIY Eurorack Module 'Midi CV Interface'

" Short and musically quite boring demo of the features of my Eurorack diy Midi-CV-Interface. In case you dont know: such an interface lets you integrate the analogue module system into the digital midi production set. It has - besides Pitch-CV and Gate - simultaeneous outputs for velocity and 2 controllers. It can learn the midichannel (and remember it) and be set to single trigger (held notes will not send another gate) or multiple trigger. It also has a potentiometer to set the glidetime (portamento). A switch lets select if all notes should be glided or just held notes.The latter gives kind of temporary glide like on the tb303. It also has 5 Volt outputs for midiclock and sequencer-start/stop (both not features in this video). More technical info on my homepage. Sorry for the bad video quality, forgot to disable manual focus."

Intellijel Atlantis Dual Oscillator Subtractive Synth Voice Announced

Intellijel just keeps on surprising with cool new Eurorack modules
Today they announced the Atlantis, a Dual Oscillator Subtractive Synth Voice

" The Atlantis is heavily inspired by the architecture and sound of the classic Roland SH-101.
It has always been one of our favorite synths and we really liked how the seemingly limited architecture allowed for all sorts of creative and musically useful sounds to be easily generated.

Just like the 101 it is quick to dial in beautifully rich bass and lead sounds. 
However this module uses triangle core VCOs (based on the Dixie core) instead of Saw core which respond much more musically to FM. 
The modulation oscillator can be used as an LFO or VCO (audio rate) and both track very precisely over 8 or more octaves.

Intellijel Atlantis 

In the mixer section you can adjust the balance of the primary oscillators waveforms including a sinewave which is normalled to the EXT IN jack. 
You could also patch in one of the modulation oscillators waveforms into this channel and be able to operate the Atlantis as a proper two oscillator synth. 
There is a switch labelled “LINK” which enables the modulation vco pitch to be based as an offset of the primary VCO. 
This is useful when using it as a stacked dual vco or when you have the mod VCO acting as the linear FM source for the primary vco and wish to maintain the ratio.

The filter section is a Roland style cascaded 4 pole multimode filter with LP, BP and HP modes. 
The LP Boost switch engages a special mode useful for the LP that produces a much fatter and prominent sound that is not drowned out by resonance (unlike the original SH-101). 
The filter self-oscillates to produce a very clean sine wave which also tracks 1V/Oct. Between the Mod VCO, Primary VCO, Sub Oscillator and resonating filter it is possible to layer up to four different pitches at one time.

The envelope section is an ADSR with a dual range switch. 
It also can be set to a looping mode which can be gated on/off externally.
The output VCA feeds into a two level output clipping circuit that you can use to get a much ballsier/dirtier sound.

Main features:
Modulation VCO: triangle core with Hard Sync and Link switch to connect pitch to primary
Primary VCO: triangle core with Hard Sync, Octave switches, Linear/Exp FM and PWM
Global modulation bus with four VCO waveforms, noise and S&H options
Cascaded 4-Pole multimode filter
Looping ADSR with range switch, manual gate, and external level (velocity) control.
Three position output clipping circuit
27 jacks for creative and complex patching options
Header on back of pcb that allows it to be linked (normalled) to the Intellijel Metropolis sequencer
Skiff Friendly

Summary of enhancements over the SH-101 core:
Triangle core vcos (with far better tracking and Hard sync) instead of saw core
Primary vco has linear FM (not just exp)
MOD Vco can be linked to the primary VCO pitch CV.
Modulation oscillator switchable from LFO to VCO
Filter is multimode, 2/4pole switchable and has a special LP boost mode
Filter allows for selection of inverted ADSR mod source
Filter tracks 1V/oct
Mixer section includes and external source which is normalled to a sinewave
Filter has built in soft clipping
Envelope has looping option, re-trigger and selectable time range
Output VCA has two stage clipping circuit
External clock input for the S&H
Patch points for every synthesis section"

Doepfer A-190-8 Midi/USB to Sync Interface Now Available

At the end of the year, Doepfer finally announced that the A-190-8 Midi/USB to Sync Interface is available starting today.
A-190-8 Prototype

Basically this module divides the incoming MIDI or USB clock messages into smaller steps.
You could look at the A-190-8 as a modular version of the MSY2 MIDI-to-SYNC Converter.
It was already announced in December last year, and besides the normal MSY2 functions this module also features multiple simultaneous outputs and added USB support.

Here are the most important features of this version of the module:
- Midi input (recognizes only Midi realtime messages clock, start, stop and continue)

- USB input for Midi via USB

-Clock outputs:
96: outputs the Midi clock 1:1 (96 pulses per measure/ppm or 24 pulses per quarter note/ppq)
32: outputs the Midi clock divided by 3 (32 pulses per measure/ppm or 8 pulses per quarter note/ppq)
16: outputs the Midi clock divided by 6 (16 pulses per measure/ppm or 4 pulses per quarter note/ppq)
8: outputs the Midi clock divided by 12 (8 pulses per measure/ppm or 2 pulses per quarter note/ppq)
1: outputs a pulse at the start of each measure

- Other outputs:
Start: outputs a pulse at each Midi Start or Continue message or generates a gate signal that remains in the high state until a Midi Stop message occurs (selectable via jumper)
Stop: outputs a pulse at each Midi Stop message
Reset: outputs a pulse at each Midi Start message that follows a Midi Stop message

- Wait control input, can be selected by means of a jumper between Gate function or Switch function: in - Gate mode the positive edge of a gate signal is used to init the Wait state, in Switch mode an external switch that connects to GND is used to init the Wait state (equivalent to Switch-Trigger)

- Wait button / Wait control input: Whenever the Wait button is operated or a positive voltage is applied to the Wait input the module waits for the next measure start until the clock signals are generated.

- LED displays for clock, "1" and start (display of Start depends upon the chosen Start mode, see above)
output voltages can be selected between +5V and +12V by means of an internal jumper (for DIN Sync applications +5V has to be used !)
firmware updates via USB (provided that there will be updates available)

HackMe Vectr Open Source 3D Sensing Gesture Controller

Now here's a cool new Kickstarter project;
The Vectr Open Source 3D Sensing Gesture Controller is a nice new way of controlling your modular Eurorack synthesizer.

HackMe Vectr Gesture Controller prototype
It's like a cross between the Korg KaosPad and some kind of (Roland) D-Beam interface (or theremin) that can control sound and effects via hand movements interacting (measuring the distance) with an infrared beam of light.
They hope to fit it all on a 32 HP panel (the prototype size is 36 HP wide).

" The Hackme Vectr is an entirely new and unique way to interact with a modular synthesizer.
Vectr is a three dimensional control interface designed for Eurorack modular system.
It senses the location of a hand over its face and outputs a signal proportional to position for each axis: x (left and right), y (up and down), and z (in and out).
So, you can control three things at one time, like turning three knobs all at once by moving your hand through the air.

HackMe Vectr Gesture Controller prototype
The possibilities are truly infinite. You could control the amplitude of a sound with the x axis, the pitch with the y axis, and the modulation of that sound with the z axis.
By moving your hand slowly over the surface, you can create subtly evolving, changing and dramatic sounds. With quick movements, you can generate bursts of dynamic audio.

To provide feedback, Vectr has LEDs ringing its active sensing area.
These LEDs light up according to the location of your hand.
It lights red for the z axis and blue for the x and y axis.
As you get closer to the surface, the red LEDs get brighter.
As you move closer to a location on the x-y axis, the blue LEDs in that region get brighter and those farther away get dimmer.
This makes Vectr visually stunning, brilliant for live play and, excellent for dark spaces.

HackMe Vectr Gesture Controller pad
Vectr can also recognize a number of simple gestures.
It recognizes swiping gestures as well as circular motions over its surface.
These gestures can be used as trigger outputs and for interacting with the built-in looping feature.
Vectr provides a menu system that uses gestures to change the system behavior.
Vectr can record up to 30 seconds of position and gesture data for looping playback.
Simply press the large illuminated switch to start the loop and release it to end it.
The loop plays back immediately and can be retriggered with swipe gestures or by external signals from a module with trigger outputs.
Vectr records as long as the switch is held down, so long rhythmic sequences can be recorded by moving a hand in an out of the active area.

HackMe Vectr Gesture Controller prototype
The loop switch can also be used as a sample and hold control.
When pressed quickly, it freezes the hand position to lock in the output.
The loop playback can be sped up or slowed by using circular gestures, clockwise for faster, counter-clockwise for slower.
The loop recording can also be triggered externally.
One pulse starts the recording and the next pulse ends it. Using external triggers to start and stop recording as well as to synchronize the playback, you can make perfectly synchronized loops.

Vectr is entirely open source. All aspects of the design will be released under cc-nc-sa 2.0 license. There will be a USB connector on the back of the device. This will allow anyone to program and reprogram Vectr to suit their purposes. Want to use it to fly drones? Make a lighting controller? Make your robot dance? Go for it."

The HackMe Vectr is a Kickstarter project, with the controller available to early supporters for 299 USD

Cheap Eurorack HP Adding Solution by Patrick Egger

Materials used
Patrick Egger posted a very interesting idea in the Doepfer A-100 Facebook Group with a simple solution to give you just that extra little bit of extra HP width for only one Euro.

The pictures are self-explanatory...

Finished project, 8 HP extra
I think it's a really smart solution, and very usable in this case as audio/headphone/CV-splitter.
This option is only suitable for passive modules (safety first), but an A-182-1 Switched Multiple would also look great there...

Jomox Bassdrum and Percussion Eurorack Modules Announced

JoMoX ModBase 09 Bass Drum Module
Last weekend Jomox announced that their first set of Eurorack drum modules are shipping...

The ModBase 09 Bassdrum module is an impressive looking module with many knobs and buttons and plenty of CV modulation options.
They also have MIDI Inputs, what makes them even cooler...

" For regular modular use, analog routable CV inputs and an analog output are accessible via 3.5mm jacks. The Gate can be configured as 0-5V (0-15V is accepted too), inversed or s-trigger.

Everything is storeable and can be recalled via encoder klick from 100 presets. But for the analog feel of modular, eight potentiometers give you the fine and precise editing of the most important parameters without stepping through menus.

E-Drummers can create complete E-drum setups, because there is an internal Jomox analog connection bus with a fast digital link which can do a submix and an FX send mix from each module hooked up to the bus.
With this system bus you won't need to use the audio outputs but instead you have a programmable bus system that can link to future master, sequencer and mixing or effects modules - which can take control over the single modules.
This makes the whole modular setup recallable and storeable from a center module like a drum machine.

Also, to link the ModBase modules to our other products, they all have a Midi interface on the rear that can be wired within the rack case and being cascaded from one module to another.
The menu selection is paged by two-colored LEDs for both sides of the menu.
Two internal LFOs which both control the tuning of the kick drum VCO expand the sound spectrum once more.

All analog parameters are either storeable and controllable via Midi. The Midi notes control the pitch of the kick drum VCO.
The modules are controllable via CV/Gate and via trigger pads for live drummers. With the trigger input, the threshold and velocity dependend dynamics can be adjusted.
Four routable CV inputs let all internal sound parameters (incl. LFOs and metallic noise) be controlled by CV sequencers. Every CV input provides an own programmable amount which can be negative too (i.e. subtracting the CV value from the internal value). The range goes from 0..5V."

JoMoX Mod.Brane 11 Percussion Module 
The ModBrane 11 Percussion Module is dedicated to all kind of sounds from classic snare to insane metallic pickaxe sound.

" In the Mod.Brane 11 there are two 2-pole filters (F-OSCs) arranged in a way that dampen is like a limited range of resonance. They can interact between each other by two coupling parameters 1_2 coupling and 2_1 coupling. Coupling is a combination of addition (mixing) and frequency modulation. 2_1 coupling acts inversely with negative values and even with positive values. So every possible feedback and interference mode can be produced.

A dual noise generator which provides either white noise or a multitone metallic noise or a mixing of both, combined with a decay envelope, can produce percussion-like and cymbal-like tones which are mixed to the rest of the membrane signal. A part of the signal excites the F-OSCs, and the other part is mixed as a noise envelope to the signal.

Two internal LFOs which control the tuning of both F-OSCs expand the sound spectrum once more."

Video: JoMox goes modular ! Expect fat sounds

" JoMox was at Modularsquare november 30 to show his new eurorack modules dedicated to drums !
On the left side of this case you will find 2x ModBase 09 Bass Drum modules obviously dedicated to kick drum, and on the right side, 2x Mod.Brane 11 percussion module dedicated to all kind of sounds from classic snare to insane metallic pickaxe sound.
We are totally in love.
Nothing fancy in that video, just exploring presets to find good combinations. We will come back later with deeper videos.
(All these modules are controlled by a Doepfer A-155 sequencer, no FX nor compression added)"

Critter & Guitari Melody Mill Eurorack Note Generation Module

Critter & Guitari announced their first Eurorack module, the Melody Mill today.

" The Critter & Guitari Melody Mill is a note generation module for Eurorack modular synthesizers.
It contains a keyboard, CV outputs, CV clock input, built-in arpeggiators, a sequencer, and MIDI capabilities.

Critter & Guitari Melody Mill
With the Melody Mill you can:
- Use the CV output to control oscillators
- Connect your MIDI controller or computer into your modular setup using the MIDI input
- Play notes, record and playback sequences and arpeggios on your favorite modules
- Convert MIDI clock into CV pulses
- Clock the arpeggiator with an LFO for strange melodies
- 'Hold' notes for drones
- Connect the built-in square wave oscillator directly to a filter or an amp

The Melody Mill generates 1-Volt per octave, trigger, and gate control voltages.
These signals are used to trigger other synthesizer modules.
Notes may be played on the built-in keyboard or received via MIDI.
The notes may be used directly to generate the CV signals, or fed through one of the five arpeggiator modes first.
Adding to the fun is a hold button and a simple sequencer to record and playback notes.
In addition to the CV outputs, the Melody Mill also outputs MIDI of the note it is generating.

A ‘smart’ arpeggiator clock selects a clock source depending on what is connected to the Melody Mill: CV clock input, MIDI clock, or internal clock (controlled by the 'Rate' knob)."

I really like the idea of such a module and also the wooden look of the buttons. i hope we'll see some videos of it soon...
The module is shipping now and can be yours for 360 USD

Random Video: Cardio Bass & Respiration Synth by Ukrets

Mark Mennings (@sensien) brought this next video to my attention.
A nice example of biorythmic/posture control of a doepfer modular.

Video: Cardio Bass & Respiration Synth

" Ukrets uses the biomusic performance and authoring platform. Performed by the Holminid with synthesis by Sensien, using a modular analogue synth. Everything is generated from live biosignals and postures, except the obligatory 808 kick that was added for structural support. The track consists of two patches recorded in succession, mixed without any further editing or processing. Jaala, Finland, July 2013."
" ...we convert the signals from the wireless sensor belt to OSC, which is then used to create triggers and control ableton. This is converted to CV."

Quick SiteTip: CatSynth.Com

Funny how most of the modular synth-lovers that i know seem to be serious cat-lovers as well.

Because of this, you might also have heard of before...

The CatSynth blog started in July 2006 and covers Cats, Synthesizers, Music, Art, Opinion and more...
Besides that, CatSynth regularly features reviews of music and art.
The focus is on modern, contemporary or experimental work in a variety of media. 

Catsynth primarily covers the San Francisco Bay Area, but occasionally find themselves in New York or such far away locales as an electronic music show in Tokyo or an underground club in Shanghai.

2Egress Studio Furniture and Cases

After the recent wave of interesting new Eurorack-modules you might run out of rack-space pretty soon...
I recently stumbled upon a Canadian firm that builds and designs studio furniture and Eurorack cases.

A few of the 2Egress Eurorack case-designs
2Egress is a three year old small business located in Toronto, Canada that specializes in technical furniture for recording studios and film editing suites.

"Growing up with an avid woodworking father, Brock inherited a love for all things wooden, and developed a passion for restoring classic racing sailboats.
These experiences have been stepping stones to the high quality, detail oriented pieces that he designs and builds today.

As a schooled audio engineer and musician, it became clear to Brock that studio furniture had become stuck in the 60's and 70's - ugly and utilitarian to excess, the standard pressboard self-assembled furniture available was not recognizing the unique needs nor aesthetic discernment of the industry.
Some time ago they had been invited to build a Eurorack case and have decided to continue building them ever since."

12U 104HP wide custom case for Damian Taylor
Recently they designed and built a double wide 12U 104hp modular case for Grammy-nominated producer Damian Taylor (Bjork, The Killers, Unkle, Arcade Fire, The Prodigy).
It houses four Doepfer PSU2’s and 8 Bus Boards, has two IEC power connectors on the rear and even a matching rear panel to compliment his studio space.
They included 1/4” connectors on the rear with passthroughs to the front of the case. 
See the building-process HERE, and the finished product with modules installed HERE

I really like this sort of craftsmanship, that's why I think it is worth posting it here.
If you are looking for a new case or rack, contact them to find out what they can do for you.
They mention worldwide shipping on their website...
Based on the pictures they seem to make good quality products with an eye for detail.
Watch their site as they will be adding some very funky cool cases in the very near future.
Loads of drawings are already just waiting to be pumped into their CNC machine...

Make Noise Sub Timbral Oscillator (STO)

Make Noise released their Make Noise Sub Timbral Oscillator (STO) and it looks quite interesting.

Make Noise
Sub Timbal Oscillator
The STO is a "compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain. 
The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.

It features:
- Triangle Core with outputs for SINE, SUB and Variable SHAPE
- Unique Variable SHAPE circuit ripples Even and Odd harmonics for subtle timbral shifts
- Linear FM input with Depth control
- EXPOnential input for deep FM, SYNC sweeps or Transposition of sequences
- SUB-Oscillator yields max bass
- S-Gate input for gating or sync of SUB-Osc. independent of other outputs
- Hard SYNC circuit which combined with Linear FM and Variable SHAPE yields harmonically rich sounds
- Pairs well with the MMG or Optomix"

Random Video: Doepfer A100 vs Moog Modular by Kevin Farrow

Kevin Farrow posted a nice video, comparing his Doepfer A-120 Moog filter with an original Moog modular system...

Video: Doepfer A100 v Moog Modular by Kevin Farrow

" Spot the difference. This is a comparison of my new Doepfer Modular A100 System fitted with the A120 (Moog) 24db Filter compared to Tom's Mighty Moog Modular.
Not bad considering the Doepfer is about £30,000 cheaper !"

Doepfer A-166-2 Logic Module Announced

Via the Doepfer A-100 Usergroup on Yahoo we found out today that Dieter and his crew are working on an additional logic module (A-166-2).

Not the new, but the 'old'
A-166 Dual Logic Module
You probably remember the original A-166 Dual Logic Module, which is a double logic device that combines digital control / clock signals.
Read all about that module HERE.
A typical application of this module is the combination of digital signals of the A-100 gates, clocks and triggers to obtain "gated" clocks or rhythmic clock patterns.

The new A-166-2 "...will also include - among other functions - a flipflop.
( The output will turn high as soon as the first pulse of the "gate stream at audio rate" appears and stay high until the gate turns low.)
Sometimes I'd like to have a flipflop function in certain patches.
A simple zero-crossing comparator could be added to this module too. 
The A-166-2 will probably also include a rising edge detector (outputs a short pulse at the rising edge of a digital input signal) and a falling edge detector (outputs a short pulse at the falling edge of a digital input signal).
I think also about a pitch-change-detector (or more general CV-change-detector). 
It outputs a signal whenever a CV connected to it's input changes (probably with three outputs: positive/negative/both). 

So far there is no front panel layout available as I'm still fiddling about the arrangement of the sockets and controls, which features will be finally included and which front panel width (4/6/8 HP) is the best compromise."

Price and availability are still unknown...

Doepfer History: MVP1 MIDI Volume Pedal

The Doepfer MVP1 MIDI Volume Pedal was manufactured from 1991 until 1994 and was available as a kit, ready built pc board or complete pedal unit (i.e. built into a foot controller).

Doepfer MVP1 with external box and
the (Dutch) Elektuur Magazine of July 1994
The MVP1 was a programmable unit that could be used as volume (factory setting) or expression-pedal.
It featured MIDI In and Out so it could be placed between your keyboard and a sound module.

Via a learn button and internal DIPswitches you could change this module's functions.
Other parameters that could be controlled with this unit were volume, modulation, portamento, aftertouch, pitchbend, and velocity.

The MVP1 was also published as a DIY article in the July 1994 issue of electronic magazine ELEKTOR which was published in different languages (German, French, English, Dutch).

MVP1 DIY-kit
Elektor is a monthly magazine about all aspects of electronics, first published as "Elektuur" in the Netherlands in 1960, and was published worldwide in many languages including English, German, French, Greek, Spanish, Swedish, Portuguese (native and Brazilian) and Italian with distribution in over 50 countries.
The English language edition of Elektor was launched in 1975 and is read worldwide.

The advantage of Doepfer's original MVP1 board was that the board was so small that it could be mounted inside the pedal.
ELEKTOR modified Doepfer's original MVP1 pc board design a little bit because they did not like that a smaller circuit was located directly under the processor to keep the pcb board dimensions as small as possible, but the electronic circuits are exactly the same.

MVP1 pedal with internal electrnics
The ELEKTOR version of the pc board was much larger and that's why an external box was necessary (as seen in the top picture).

The last MVP1 units were sold somewhere between 1995 and 1996.

The kit costed between 40 Euros (PCB only) and 70 Euros (PCB and foot controller)
The ready built unit was available for 110 Euros.
Around 600 units were manufactured.

The user manual is still available on the Doepfer website HERE

Doepfer A-100LC3 Low-Cost Case Announced

Quite fast after they released their A-100BP case, Doepfer has now announced another new case to house your eurorack modules.
This time it is a low-cost case that will probably be available from the end of 2013.

Doepfer A-100LC3 low-cost case front view
The A-100LC3 is the "small brother" of the low cost case A-100LC6 (and A-100LC9).
It is very similar to the A-100LC6 but offers only one row with 84 HP for installation of modules. 
The A-100LC3 is equipped with one power supply (1200mA) and one bus board. 

Because of the limited space the power supply of the DIY-Kit #1 with an external transformer is used (same as for the DIY-Kit #1). 

Doepfer A-100LC3 low-cost case
On the left side of the case the connector for the external transformer is located.
The external transformer is not shown in the above pictures. 
The outside dimensions in mm are about 445 (width) x 160 (depth) x 150 (height). 

The price of the A-100LC3 will be around Euro 180-200 (including external power supply for 230 or 115V AC, without modules).

One of the benefits of having the connector on the side of the module IMO is that it can also be used on its back, as some kind of (high) skiff, but I wouldn't look up strange if Doepfer soon announces a skiff or another case...

Intellijel Metropolis Preliminary Info

One of the most interesting modules i have seen in a while has been sent out to various testers in the last few weeks.

The original:
RYK M-185 Sequencer
The Intellijel Metropolis is a 'complex multi stage pitch and gate Eurorack sequencer', based on the RYK M-185 sequencer from the early Roland M-100 series.
This RYK module has always intrigued me, and i was always hoping someone would bring this style of sequencing/programming to the Eurorack.
(Watch some of the original RYK M-185 demos HERE and HERE)

Intellijel worked out an agreement with RYK earlier this year to create this only official Eurorack adaptation of his brilliant sequencer design.
It has taken many months to procure all the special parts and the design has already gone through several hardware revisions. 

Looking at the prototype picture that i see floating all over the internet, i see it has a quite lot of extra features.
It's a big, space-consuming module (34HP wide) and it looks very impressive with its rows of sliders for pitch and pulse count, the switches for different gate modes, and buttons for slide on/off and skip step.
All the core original M-185 functions seem to be there...(Read more here)
On the left side of the module is a 5 digit LED screen, buttons for complex programming/editing and a few knobs for AUX-levels, Gate- and Slide-time plus one for data input.

Intellijel Metropolis Sequencer
Some of the features :
-Sequencer modes:
Forward, Forward-fixed, Reverse, Reverse-fixed, PingPong, PingPong-Fixed, Random, Random-fixed, Brownian, Brownian-fixed
-TB-303 style slide (constant time portamento) with adjustable time
-Stage skipping (double click slide buttons)
- Internal quantizing with selectable scales and keys
-Can act as a master clk with BPM control or slave to an external (using clk src function)
-Save/load panel settings
-Internal clock divider
-Sync output (sets output pulse on last clock step of a sequence, used to slave other sequencers via reset)
-Two assignable AUX inputs which can control: gate length, transpose, key shift, root shift, sequence length, and step divisor.
-config menu to set slider pitch range, clock div type, clock offset
-tap tempo when in internal clock mode and tempo lock with bpm detect in external mode.

-All menu actions are one level deep. i.e. press the menu button and spin the encoder.
There are no hidden levels or sub menus.

Video: Metropolis Scrutineering by Dudadius
Metropolis Scrutineering from dudadius on Vimeo.
" First go around with the Intelljel Metropolis. This is a pretty basic setup; I didn't get into using the aux inputs to modulate things within the Metropolis. I'll try that next! As you can see though, the Metropolis really lends itself to performing and improvising. Very hands-on and easy to go all sorts of crazy ways, melodically. Similar to the Rene, in that regard, but from a totally different point-of-view.Patch notes. Pamela is sending clock to Metropolis, Trigger Riot, Modcan Dual Delay, and Sound of Shadows.
Metropolis is sending the same note info to three different oscillators. The third one going through a uScale first to create intervals. All going into the Dubmix. The Trigger Riot is controlling Tiptop drums, mixed through a VCA Matrix then an M277 for a little grit. That's into channel 2 on the Dubmix, where I add a little Spring Reverb at one point.
The kick and snare are ultimately doubled with the Cwejman BLD and DPO. Lastly, I dialed into some sustained notes on the Pressure Points and a Modcan Triple OSC. The uStep is advancing the Pressure Points.
I had some troubles with the Trigger Riot losing sync when I would change presets.
I'll have to delve into that some more."

Random Video: Modular Synth - A-143-4 and A-149-1 Orchestral(ish) Sounds by IsVisible

Here's the latest modular synth video by IsVisible.
It's kind of orchestral-ish and features Doepfer's A-143-4 and A-149-1 modules.

Video: Modular Synth - A-143-4 and A-149-1 - Orchestral(ish) Sounds
Modular Synth - A-143-4 and A-149-1 - Orchestral(ish) Sounds from isvisible on Vimeo.

" 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."
