That 4x4 mixer doesn't seem worth the space. There's better ways to do most of that.
Add as many active multiples as you can stand to spread those expensive-to-generate signals around, accuratly.
I like the MST '07 Buffered Multiple and the Rides in the Storm QAM.

Another boring module is the lowly offset/attenuator.
The Doepfer A-183-2 is a simple, clean one channel 4hp one.
The Frap Tools 321 is a nicer 3 channel one in 6hp
The Frap Tools 333 Sum and Distribution lets you transpose and wobble 3 channels of note CVs, and more, in tune.

These utility modules are the glue that unifies everthing you have into a systemic whole.

I wish people were this passionate about using more active multiples.

Supporting the BDS movement's call for a cultural and economic boycott of Israel, is not biggotry my man, its the bare minimum in times of genocide, ethnic cleansing and apartheid. When you buy goods from Israel you support the Israeli army budget, West Bank apartheid and building of illegal settlements. If Israelis wish to do the right thing, they shouldt do business from withing Israel or pay tax to the Israeli apartheid state.

Bad and lazy comparison, i didnt express nationalist or patriotic sentiments like the ones Banksy criticizes, i called for a financial and cultural boycott like the one that ended apartheid in South Africa. Not aiming at individuals, I support BDS and any antiimperialist or decolonial movements globally.

PS. Cultural boycotts work, read "Assuming Boycott: Resistance, Agency, and Cultural Production" and try again.

hello, a lot of the time i see people putting modules on for free, but then demanding a high price over paypal, modules needing to be sold alongside others, or even needing a physical cash transfer. can we find some way to stop people gaming the marketplace sorting system in such an underhanded way? one thing i think we could do is add an option to sell multiple modules in one sale block, as a "bundle".

Hey everyone,
I just acquired an Easel Command. There is a sound when I lift/tilt the unit that sounds like something sliding about. It doesn't sound like something loose or free and sounds as if it's maybe a ribbon cable sliding an inch or two, back and forth.
Does anyone have one that they can grab and tilt for me to see if this is normal?
Thanks for your help!

Funny jam, taken as it is.

Design based on the ARP 2500 from Willem Twee studios in the Netherlands, but adapted to fit a Behringer Eurorack Go case.

ARP clones used:
* 4 1004 oscillators (all low or high range)
* 2 1047 Multimode filters
* 2 1006 Filtamps (serving as final output stages)
* 4 EG's (2 1003 ADSR, 2 1033 DADSR)
* 1 1005 ModAmp
* 1 1036 dual S&H,
* 1 1050 Mix Seq and 1 1027 Clocked Seq module

The noise clone module has been left out (too much real estate for what it is), and replaced by other modules I deem more useful, also providing me 2 different noise colors.

Via Tindie (https://www.tindie.com/stores/euroutilities/) I bought 5 add-on modules each 2 HP wide. They are represented here by 2HP blank panels:
- two of the 1004 oscillators will get individual outputs for all unmixed waveforms
- both 1003 and 1033 dual EG will have their own individual gate and trigger inputs
- the 1036 dual S&H will have individual clock and 2 (brownish) noise outputs.

Next to these I add some utilities, that esthetically should not 'kill' the ARP look.
- Ladik's quad quantizer (alumininium panel, not the black one as in the picture)
- MI Kinks clone , offering white noise and other stuff
- MI Links clone offering buffered mults and a precision adder and a simple mixer
- 2 DBZ 3 channels mixers, usually for mixing oscillators into the filters

It's a fairly standard set up, allowing me to create sounds with 4 oscillators + 4 filters, a full binaural 2 osc synth (separate stereo paths), a standard 2 voice synth with 2 LFO's , or creating two separate synths, one played via keyboard, the other one with the sequencer.

Btw, have you considered a drum machine? I'm all for drums in Eurorack, but three voices might be to limited.

Good point ! I didn't realized the depth of the A111 6 is 50mm ! And yes I will go step by step smoothly starting to use my other modules and gears meaning that I will prioritize the matrix with the effects along the pamela which I think is a must have

Maybe consider a multiple module somewhere? (E.g. replace the Vowel module with the 2hp Mult module.) Can be very useful to multiply some of the modulation signals.

Another important thing to keep in mind is that your case need to support the depth of the modules. E.g. the Behringer Go case is very shallow, so it won't fit deep modules (I think it's about 30-35mm deep).

EDITED May 14th, 09:10

Generally you want to spread out your buys, and start from a corner with the essentials. This way you can alter your plans as you learn more about your gear.

What you start with depends on what you already have, and the bare minimum to get something going. That probably means you need to start with power and one or more voice.

Do you have a sequencer available? If not, the Pam's probably a must. (You probably want the Pam anyway though, it's very useful.)

What other sources of sounds do you have? Can it be combined with eurorack? (Some synths provide CV points.) Maybe you could start with one Drum2 and either the A-111-6 or the Beehive, depending on which you like best, but it really depends on what you already have.

Do you have a mixer, and does it handle the level of audio coming from eurorack (it's high compared to most other synths)?

You probably want an effect module too, and the FX Aid should go a long way there. It's not essential, but gives you lot more options.

Hope this gives you some ideas ^_^

Thanks for the review and the sugestion for the filter, djing myself I often use (especially with ambient) the filter for transition even if I try to not over use it. Quite happy already to have placed a tiny filter in insert effect
Now the question is what should I purchase first haha ... it's so expensive

EDITED May 14th, 01:24

Oh yeah, another thing while we're planning modules and buying cases...
My hopes get dashed by this too often: module depth vs. case depth

I ended up recommending modules that might be too deep for the case you want.
It's always something.

Impressive how much you're able to get into 104hp! I don't own any of the modules myself (except Pams), but in terms of their functionality it should deliver what you want.

My only thought is that I would've liked a bigger knob for the filter; I'm thinking of a DJ-like filter where clockwise is high pass and anti-clockwise is low pass - it's a cheap and effective way of creating interesting transitions in your music.

That said, maybe that doesn't fit your style. Should be a interesting setup nevertheless (I think the Matrix mixer and the Mimeophon could be quite good) ^_^

If you want to tuck away power cables, you can consider a power supply that's inside the rack. It's a bit more hassle than just buying something like a uZeus though.

And remember to always double-check that the power consumption requirements (at the bottom of your rig) is supported by the power supply. I read somewhere that it's good to have 10-15% "free" capacity, but I'm no expert on this.

Have you considered an external sequencer? I have an Oxi One mk1 which I'm extremely happy with ^_^

Also, I think you should consider some modulation sources, like LFOs. Pam's Pro, which is part of @noodle_hut setup, is a great utility for this.

You might also be interested to look into low pass gates (I'm personally a fan of LxD here) to combine with the various audio outputs from your Mother-32 and Labyrinth, and might even a submixer to combine multiple audio signals together (I have the A-135-2 for my Mother-32).

That said, you're on a great start, starting with semi modular synths are a great way to get into Eurorack, and with the pedals as effects you should have a lot of options audio-wise ^_^

You have to power it from the front.
All of us here are haunted by wires.

What you've planned will do a lot already, it's lots of enough.
Just install a blank panel as a koan to disclipline.

This is a little cleaner and cheaper too.
The Behringer seq does more, costs way less, and can act as another system clock.
The nanorings is smaller. works the same, and is easier to find.
Finding a Beads, or any authentic MI module, is tough now. Do you already have them?

I put them in an order so they can often interconnect with those nice short yellow Doeper patch wires.

Nice set up, you've given me things to consider and some great ideas. My dad has made some wooden end cheeks so I'm good in that department.
Regarding the PS can it be powered at the back? I see the socket on the front panel but is there also a back connection? I'm OCD when it comes to hiding cables.
Do you have a modular grid list of your modules to share? If so that would help me in doing some research on other modules. Thanks for your feedback.

Hello, I try to assemble in a 104HP rack a techno/ambient techno live setup that I can carry, plug and play/jam on the console of different venues.
I'm living in Saigon where eurorack modules are not available apart behringer ... I take the opportunity to travel to Europe to sart getting these new modules.
Thank you for your help and advices, the idea was to get a little drum kit, 2 synth voices, insert effects that I can use with the matrix mixer to build up and modulate sounds during the performance, using the pamela and random8 for the sequences and modulations (or arturia keystep pro for the sequences ...) and a compressor at the end to glue everything nicely.

I built a three tier Moog like this. The red frame is from a guy on Etsy that 3D prints them and it wasn't expensive.
https://www.etsy.com/shop/Releas3DPrints?ref=shop-header-name&listing_id=1458591935&from_page=listing
Very sturdy and nicer than I had hoped. He prints them in colors other than red.
Really good work. Currently just $75. Can't beat that.

I kept the wood end cheeks but you don't have to. I thought they would end up lost in a drawer so I kept them on.
(To do that, I had to get 24 longer screws than what came with the frame.)

For the top row, I used the very nice empty Moog case that they used to sell.
They don't make them anymore, so you'll have to hunt around, but they're out there. A perfect match.
Unlike the other two, that empty case doesn't have it's own power so I used a Behringer PS,
running it all with one (big-enough) wall wart with a 3-way splitter wire to power the whole thing.

I did end up swapping rows 1 and 3 to keep the wires out of the way of those nice Subharmonicon knobs.
Worked way better on top. Here's how it ended up, as "The Squealer" (that really needs some mults).

For me, patch cable spaghetti never gets that bad.
I get lost on discovery road and forget what I'm doing, way before I run out of jacks and the wires to connect them :)

EDITED May 12th, 17:59

Thanks for the feedback I will look into the A-185. I have had the two Moogs for a while and pretty familiar with the subharmonicon. I really like it and have used it as the basis for a couple tracks, using one sequence for a bass line and seq 2 to form a pluck sequence over the top. From watching some videos it seems the Spectravox and Labyrinth are even more experimental so not for me. I thought about a second M-32 but decided to go for more variety.
Yeh the reason I ask about the ribbon cable is to consider how I am going to connect them all together, as the Moogs are in cases. I will take them out and mount into the rack so I can take advantage of the power supplied by ribbon cable. Looks like it's going to be cable spaghetti for the audio tho.

6hp left?
Doepfer A-185-2v Precision Adder.
You can then have one sequencer transpose the other, in tune, up or down,
and then share those new notes to that nice top row.

The power supply is fine.
The modular ribbon cable never carries audio. Just power and ground,
and sometimes, one gate for event on/off, and one cv, usually for notes.

Those two Moog sequencers are very different animals and can play nice together,
but the Subharmonicon is a demanding instrument to tame and integrate into a mix.
It's harmonic based, and always brings it's own special notes.
Spectravox is even weirder. For me, both of them are more for seasoning than a main course.

If you like that three-tier Moog format, consider maybe two Mother32s might take you further.
That'd be fun.

Hi new here and to the world of Eurorack, and I know my life will never be the same. I don't plan on going down the rabbit hole completely (famous last words haha), as it is more an addition to my current set up and I am a guitarist producing ambient music. I just want to have something to generate textures, sequences and happy accidents. What I have in mind is very basic. I already have a Moog Mother-32 and Subharmonicon. My dad is making me a nice timber three tier rack and I want to fill the third (top) tier with some modules and connect them all together no wider than 60hp (thanks for the idea Loopop).

So I am guessing some euro channel, a power supply and a mixer are the essentials, but thinking a couple of MI clones like plaids, marbles, rings ya know - the standards which are probably pretty cliche for hard core users but I really like the sounds. I have a board of full pedals so no needs for effects, plus I have some synths, drumlogue etc. Would be great to get the opinons of some much wiser in this space any advice is really appreciated, this looks like a great community.

• image below is what I have in mind so far
• is the power supply a good choice? Current should be more than enough.
• this may be a dumb question but does the ribbon cable carry audio?
• The sequencer module is probably overkill given both Moogs have one but I'm not sure what else would compliment this little rig any suggestions?

User Benwah
It´s not a bad seller, but I would like to give an important hint, since he lives in Island. Be aware, that you need to pay a reasonable about of taxes, since he naturally declares shippings with full module worth and Island is in this matter NONE-EU. A hint from Benwah or even better a info in his ad would have clarified this upfront.
There are other options to ship from Island, which doesn´t cause such high taxes, since I got already in the past other stuff from there without any additional costs.
So, just be aware of this. Otherwise Benwah is a nice seller!
Best!

I had ericas dual fxs, wasnt happy with it
I went with Ghost and its banger

You're totally right; I was being stubborn about the need to include percussion in the rack. Offloading to a drum machine like an Elektron Syntakt seems like a more cost effective and playable option. And I hadn't even considered how much of a PITA it would be to dink with the drum modules as they were situated, let alone mix or modulate.

Based on your feedback, I've taken another stab:

In focusing on four voices (Oneiroi, Vhikk X, Pluck, and Vowel), the priority should be in accomodating sufficient sequencing, modulation, and mixing. It seems viable, but I just want to confirm the following:

• Too many filters?
• Too few envelope generators?
• (Catch-all) Suboptimal use of rack space?

Thank you again for all your advice and help!

EDITED May 9th, 18:50

You're welcome, I'm glad that you found the thoughts helpful!

There are two main things I would address with the latest iteration of your rack, and they are both related to the percussion modules, some of which you already mentioned in your last paragraph:

1. There is still a deficiency of mixing capacity present for the percussion modules if you intend to use all of them at the same time as the Vhikk X and Oneiroi. In order to use all four percussion modules simultaneously, you would be occupying all four channels of your stereo mixer, leaving no room to use the other voices. You could use the four channels of the Quad VCA as a mixer, but then you miss out on having the VCAs there for creative modulation purposes. You will probably want to add a four-channel mono audio mixer in there, at the least. Or more VCAs.
2. Those percussion modules are so small and tightly packed that it's going to be a struggle to enjoy using them. And trying to use them in any sort of live application is likely going to be frustrating, unless you intend to never make any adjustments to their knobs. Notice how the other modules are designed with more space between the knobs and jacks, and even some of those are tight and not the most ergonomic.

My recommendation could go two ways:

1. If you are set on having a kit-worth of percussion modules in your rack, I would recommend going back to the original WMD ones and adding at least 50% more rack space. But really I think you would be better off doubling it, either as a case that is twice as big or a second one of equal size.
2. Take the percussion duties out of this rack and go with an external drum machine. For the same cost as the trigger sequencer and miniature percussion modules in the latest rack iteration, you could get someting much more practical, user-friendly, and capable for percussion duties.

I hope those critiques don't come off as too harsh, but I think they are valuable things to consider.

I hope some of that is helpful again!

Tunç Çakır Introduces New Project Groovesizer with “Yes, Sir Right!”
Electronic music producer, musician, and sound engineer Tunç Çakır releases his first single “Yes, Sir Right!” under his new project Groovesizer. The track is available on all digital platforms as of April 10 via the Netherlands-based Wic Recordings.

Groovesizer is positioned as a project in which Çakır reinterprets his long-standing musical background in a new form, bringing together the improvisational language of jazz with the sonic world of electronic music in an organic unity. The project is built on a performance and recording practice where acoustic and analog instruments coexist, with real-time interaction and generative structures at its core.

About the Artist
Tunç Çakır stands out as a versatile musician, producer, and sound engineer, working across electronic music production, jazz, and Latin music, both in Turkey and internationally.

Throughout his career, he has been involved in hundreds of recordings and live performances, developing a distinctive position in contemporary music production through his interdisciplinary approach. As a co-founder of VAEMI—one of the pioneering initiatives in analog synthesizer manufacturing in Turkey—he also maintains an active practice in electronic music technology.

At Volt.Age Studio in Istanbul, he continues to produce, record, mix, and master projects for a wide range of artists, drawing attention with his hybrid approach that combines analog and digital techniques.

On stage, he has shared performances with notable figures from the jazz and pop music scenes, further refining a musical language centered around improvisation and rhythmic expression. This approach intersects with his contemporary electronic productions, forming a unique artistic identity.

About the Track
“Yes, Sir Right!” is an instrumental and experimental piece positioned at the intersection of hip-hop and jazz aesthetics. With its groove-oriented structure, improvisation-based approach, and layered sound design, the track deliberately blurs the boundaries between composition and real-time creation.

The piece highlights a balanced interaction between distinct musical identities. Gökhan Sürer’s Wurlitzer and synthesizer layers shape the harmonic texture through both classical and contemporary perspectives, while Barış Öztürk’s electric bass performance provides a strong and fluid foundation for the groove. Efe Çakır’s scratch contributions introduce a rhythmic and textural layer that directly references hip-hop aesthetics.

Tunç Çakır, through drums, synthesizers, and overall sonic direction, establishes the main axis of both the rhythmic and structural integrity of the piece. This multi-layered construction emerges not only from individual performances but as a result of a collective musical reflex.

The recording process was primarily carried out at Volt.Age Studio, following a production approach where analog equipment played an active role. Drums, bass, synthesizers, and scratch recordings were largely captured here, preserving the feel of live performance. Additional synthesizer recordings were completed at Gökhan Sürer’s studio.

During the production process, sound design and programming were developed through a hybrid system combining analog signal processing, performative recording techniques, and digital editing methods. This approach enabled the track to achieve both an organic and highly detailed sonic character.

As the first release of the Groovesizer project, this piece also represents the starting point of a broader musical language that will continue to evolve in live performances.

@Chace, thank you so much for your feedback on the first version of the rack. Both thorough and instructive. The lack of modulation was entirely the kind of rookie mistake that would have rendered many of the voices as too rigidly defined.

I like the idea of sequencing on Metropolix, as its very jammable and lends itself well to multiple styles. After some more thought, I think I can ditch Desmodus Versio and go with the reverb on Sealegs and Oneiroi.

If I were to keep the percussion in the rack and not have it be solely for drone, I'm thinking the Tubbutec Drummertime might be a better fit in this case than the Metron, and although I love the sound of the WMD perc modules, I can't justify the combined space of the Metron + those modules. A refactor might look something like this:

Of course, there's too little in the way of mixing for this rack, but it's a step in the right direction. Scrapping the percussion all together would free up space for mixing + modulation. If you have a minute, let me know what you think.

EDITED May 8th, 01:00

Exploring the new Clock Bender module from ADDAC. Three patches, each with explanations.

Like @PragmaticusMax says having an outboard mixer is a good idea and you can pick up second hand or new mixers pretty cheap online, though its also good to place sub-mixers around your modular to bring some of the parts together. So adding a Matrix Mixer is good as a way to swap and change singal routing before hitting the effects, then post-effects grab a stereo mixer (having the ability to Pan your signals is nice), then the Befaco Output Buss is great to bring all the signals together whether you got for an expernal mixer or not.
