And yes, I do have this many Maths...

Wow, that's impressive. Are you gonna be keeping Maths in your main racks while you do this, or are you covering the functionality in different ways? Just curious 'cuz I'm always interested in how people replace Maths.

I might do a writeup or a video or so of the results (me getting all tangled up in a mess of wires).

I think I speak for us all here when I say, yes, please do!


Thanks for the response Jukeshoe and HG synth.

The idea came to me after watching a youtube video where they explain 20 or so different ways to use Maths. It's kind of an attempt to build something of an analog computer in eurorack format perhaps. I do have other cases with all kinds of modules but this feels like a nice experiment / challenge. And yes, I do have this many Maths...

I might do a writeup or a video or so of the results (me getting all tangled up in a mess of wires).


Very nice! I also love the bass! Your setup is actually vaguely similar to mine in the general concept, instead of a Rhodes and an Osmose I have a Casio Privia Px-870 and a Nord Wave which I use in conjunction with the modular. Anyway you got yourself another YT subscriber. I really like your "Silver Towers" jam as well.


It's been already a couple years since I started my YT... I started recording with only 3 or 4 modules and now I'm starting to get to a point where I feel the setup is starting to feel complete, I will probably switch a couple modules around still and I want an analog polysynth but the case is capable of making a full song on its own...

I love how the bass came up on this one, the GStorm SH-5 dual filter has an amazing sound, to my ears it really feels like a Roland filter... I'm running through it a couple waveforms plus some sub from a nano On, then adding some multi band distortion from the Cosmotronic Cosmix to get that crunch.

Hermod is the brain sequencing all the melodic voices and a clank chaos is triggering the percussion.

Let me know what you think!


I would like to be able to search between a minimum and maximum HP width.


I have no reason to post a public rack.


Agree with Jukeshoe. However, if you DO have that many Maths and go through with this, please, please film the results!


ModularGrid Rack

Ok, this was a neat challenge. But to be honest, I think my solution might need some work. I like where Sweelinck was headed (particularly with the Morphagene), as well. Maybe one of the real power users will come along and give some suggestions. But let me show you where my thinking is leading, and you can do with that as you will.

For starters, I kept almost all the modules you've already gotten, only switching out your passive mult for a buffered mult. A passive mult does not do as good a job as a buffered when multing signals; if you want to mult 1v/oct signals, you'll want a buffered mult so there is no drop in voltage. Also, I'd get a multi-cable rather than a passive mult, to save space. The other thing to consider is that the Rene, as badass as it is, takes up 32hp. That's pretty dear for a sequencer, even one as powerful as Rene. You have 104 hp to use (if the above case is accurate), don't waste nearly a third of it on a sequencer. Get something off rack like a BSP, or go for a bigger case so you don't have to sacrifice other modules for Rene.

Keeping in mind that you are interested in dark ambient with a hint of generative, I did the following (listed by function).

Top Row: Random voltages, VCOs (3 v/oct ins), multimode filter (2 inputs), mults, Maths (so many functions, but at most basic, a mixer/attenuverter/function generator), audio manipulation in the form of uClouds and uRings, function/envelopes/quad cascading VCA.
Bottom Row: Clocking, modulators, attenuverters, S/H and T/H, sequencer, precision adder, sequential switch, uO_C (so many functions, only two levels of menu diving), and end of chain VCAs, effects, and mixers.

My thought is that you could use the bottom row to supply motion, modulation, attenuation, triggers, gates, and sequences. These can be manipulated or quantized (which Rene can already do, but what if you use you S/H for a melody?) or so many other things using uO_C. After that you have another VCA and then end of chain processing. I give you for effects the Happy Nerding FX Aid XL, which sounds great, though you will want to have a printout of the different settings at hand. There's a new version out with a screen, but you don't have the hp for it at the moment.

The top row has sound sources, giving you 3 digital voices that come out of the VCOs ready to go. However, if you wanted to filter further, the Filter 8 gives you plenty to play with. And Joranalogue always throws extra functionality into their modules. Then Maths, which is so handy it needs its own post. Then sound processing in uClouds and uRings. I generally prefer the real article to clones, but it makes sense with MI's situation and your hp. Finally, function/envelope generation and VCAs to craft the shape of the sound.

My typical approach to building a rack is to try to think through the signal path as I plan. From beginning to end, where might I need to send voltages, or what parameters will I want to mangle? That way I can start thinking about the system as an instrument rather than a collection of modules.

Finally, there are utilities. These are hard to figure out without trying them, unless you're already blessed with electrical engineering experience. I mean, how are you supposed to know that sequential switches can be your best friend when building longer sequences, or that precision adders rock, or that comparators are game changers for generative music? The uO_C, particularly with Hemispheres loaded, gives you a chance to test them all out and decide what you actually need. In general (adapting something Sweelinck said in another thread), if you think of your system as a building, the oscillators, filters, and fancy modules are rooms, but you need the utilities to act as hallways and corridors (and sometimes fun-house mirrors) to get from room to room. I highly recommend looking up some videos about different utilities to get a better sense of what they do. Loopop, Mylarmelodies, and DivKid were sources I went to when I was figuring this out, and I found them invaluable.

Anyways, maybe one of the really experienced folks will tell you something different. But it looks like you're on a good path, you just need to think more about the architecture and connecting pieces of your system.

Good luck!


Looking for a bit of tips and feedback

I am building a Matyhs only rack. I want to see how far I can get with a case with only (mostly?) Maths in it.

Looking for:
* creative ways to patch Maths(es)
* your experience (or things you have seen) in using Maths creatively
* how far you think a system like this can go (and whether only Maths is feasible)

Thx people!
-- cassek

First of all, interesting idea, and I wish you luck in your attempts at a Maths only rack.

That said, just because Maths can do many different things, doesn't mean the way it does those things are ideal, or even workable. Take Maths as a 'VCA'...it's possible, but only as the crudest version, and not very workable.

If you happen to have this many Maths, more power to you and I hope to see some of your results!

If you're thinking of shelling out for this setup, I'd consider long and hard if other modules, actually geared toward a particular functionality (such as VCA, VCF, etc.) might not get you farther.

Otherwise, the approach kind of reminds me of zero-input mixing setups a bit. Which might be fun. :)

Hi,
Thanks for the picture! I couldn't post it like that.
Yes indeed more ambient than dark…
Thank you very much for your recommendation sweelinck! It looks great and very complete!
I will go and find out about each module and watch videos, thank you very much 🙂
I will come back to you if I have a question about one of the functions of this rack

Thank you dub007 it reassures me to tell myself that I made the right choices and I agree sweelinck did a great job 🙂

If anyone else has another rack recommendation / idea to open my mind, I'll take it 🙂


Spend time with what you have... It's a good selection. Sweelinck does a great job of finishing out the case with some nice options based on what you mentioned and I agree... Filter, mixer, fxaid xl or pro and outs would be my next steps as well. All very personal choices... Put your research hat on and happy wiggling


Yes. Even with the jumper removed though, it looks like you are probably pushing the -12V rail close to it's limits. So definitely remove the jumper, but pay close attention to the lights on the UZeus when it powers on. If they blink when you power on then that means you're probably pushing it too hard. All the lights should turn on immediately. Also feel the faceplate of the UZeus after you've had it on for awhile. If it feels like you're going to burn your finger then again, you're probably pushing it too hard.

You need to get in the habit of looking at the power consumption numbers listed in Modular Grid to give you an idea of how much power your rack is using. Yeah it's just a rough estimate, but in this instance it's 478 mA on the -12V rail, that tells you right away that you definitely need to remove the jumper. Given all the space you have left in the rack, you're definitely going to need more power for that rail when you add more modules. A 4MS Row Power module might be a better idea for the remainder of the rack (it provides more power on the -12V rail).

I built another Case :
ModularGrid Rack

and wanted to use the uZeus with a 3000 mA PSU Adapter. When i turned it on the -12v led didnt light up, but the other ones did. Some modules powered on, too but I quickly turned the PSU down because I feared of destroying anthing.
I also found something in the manual of the uZeus regarding the -12v rail:

"The –12V rail uses a switching regulator. This switching regulator needs to
have a minimum load of 100mA (out of 500mA) at any given time. The
uZeus has a factory setting to self consume this current. If your uZeus is
powering more than four (4) analog modules you can then disable this
setting if desired to make this 100mA available for use by your modules.
With the uZeus powered off, look for header J7 (located below the blue
resistor) and remove the jumper. Re-insert the jumper such that it comes in
contact with only one pin. Once reinstalled in the system, the uZeus will
provide the full 500mA of –12V power for your modules"

Do I just need to remove the jumper? If not, what are the best steps to debugging?

Thanks in advance!


Since I don't hear anyone coming, here is a proposal on the basis of your indications. But beware, others are much better at this than I am. I hope for your sake that they will come to our rescue.

I’ve given up browsing racks as there are too many useless public random wannabes and duplicates.

Maybe those people who have all the private racks only use this page as a place to organize their racks
-- ferranadsr

That’s exactly why all my racks are private - why would anybody be interested if I swapped two modules, or added something new?

If I thought my rack was good enough to contribute then I’d be happy to share, so lose the private/public terminology and just have an option to share your rack - if it’s worthy ;)


Bravo, Champagne! We are free. And 'Private' is a clear enough term. Well, one could also imagine 'Just married, do not disturb', but I'm afraid that would arouse more curiosity :(

Because it's technically no one else's business regardless of their reasons for wanting to look. I even sometimes get paranoid that MG staff take liberties by being able to look at any old private racks they like "just cuz".

It's not that I'm hiding anything in most cases (no pun intended), though I have uploaded some non-existent, hidden "concept" modules on here which may or may not ever be realized. And I'm also not here to impress people. I use the grid for planning my racks, both real and theoretical, sometimes in multiple, messy iterations. Why does anyone need to see that? More practically, why might I want to tip people off to what unobtanioum modules I'm scoping out at any given moment? >:3

If I want opinions, I'll ask. I'm not spending 6 hours obsessively moving squares around for any of you, though!

Hi all !
I come to ask for your help to help me continue filling my case :)
I would like with my modular to be able to do ambient / dark ambient (and to be able to play it live if I can do it).
But I would also like to be able to create dark atmospheres and fx for my techno tracks.
I am also very attracted to generative music.
I already have all the modules indicated in my rack.
For now I use an analog four to clock the rené
I looking for If possible modules with not too much diving in the menus but I accept anyway.
I also specify that I had an Erica synth black polivoks filter that I sold, because i would like a more complex filter.
Could you help me to find somes ideas of a rack that would work well ?

I don't know all the modules on the market and their functionality so it's hard to get an idea of my "perfect synthesizer"
So I bought these modules because they attracted me or were recommended by friends but I don't have an exact idea yet of how I want to work with my modular apart from what I have said above.
So everything is not very well thought out upstream even if I think that I have not made a bad choice so far and that I like each of my modules.

I haven't fully grasped the eurorack world yet, and I don't have a sharp enough mind to think through a complex patch and get exactly where I want it.
But staying only with the modules I currently have does not help me move forward because I quickly have limitations in all my ideas.
that's why i need you

For now I can use effects with ableton to save money and space.
Except if you advise me rather to have eurorack effects?
I wouldn't mind being able to play it without a computer.

I think I'm not bad modulation for now.
I think I would need a new filter, several other vcos, I had the Honda piston in my sights.
In utility I don't know yet what I might need apart from a mixer and an output module (because I currently take the stereo output from the cloud) and a clock to be autonomous.
and maybe effects?
I'm waiting for your recommendation .

If you can advise me on what I need to achieve my goals that would be great
see you soon 🙂


I'm brutal with my tidying, racks never private.

Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.

Oh thanks a lot for the topic! It reminds me I should set everything to private because I really have to clean up my racks, it's such a mess. But you know how it is, tidying up, we keep putting it off... Yet I can almost feel the dust between the pixels. Fortunately, the cat is there to keep the mice away :)

Exactly, what else ? Do you want to see people your finance plan or shopping list ?
I just discovered that a few of my racks accidently were not on private, i wonder if anything was changed here with that checkbox being off on default if you make a new rack.


Yes I know. Maybe those people who have all the private racks only use this page as a place to organize their racks and make the shopping list without wasting paper. His intention may not be collaboration and sharing. Perhaps they only use it as an office tool, like Word or Excel.


...they don't want to share the secret sauce.
-- Sedalus

thank you for that one :D

...I normally have my current rack and some variation of it as public...
-- ferranadsr

that sounds pretty normal to me.
as stated in my initial post - i am curious why people set all of their racks to private. without judging anything...
(i have added ALL to the topic title)


I still have the WE Transfer link, if y0u PM me you can have it - if that was adressed to me.


Hi,
I normally have my current rack and some variation of it as public, but I have drafts, lists and power draws as private. I don't see the interest that a consumption calculation of the modules may have for the rest of the users, especially when they are the same modules that I have in the public racks.


It's because their mix depends on that super secret module combination you don't know about yet, and they don't want to share the secret sauce.


Don't support a company that does shit like this:

"A further 20 anonymous forum users were added as defendants in the $250,000 suit for making “false, defamatory, and libelous” statements, ranging from general complaints about Behringer ‘copying’ other products or using business practices described by one poster as 'underhanded.'"

If you have to use your corporate lawyers to shut up random forum users about your intellectual property theft... there's a good chance you're doing something wrong.


Combined the two into one module, total HP from 13 up to 14 but reduced the depth from 45mm to 33mm, I'm guessing that's where/why the additional power draw manifested. I'm a little annoyed at my Batumi+Poti combo because the 3HP expander could easily be 2hp and so you end up with an odd-HP module to find a place for, but they aren't leaving my rack anytime soon. This looks like a skiff-friendlier alternative if you really love Batumi, but I'd probably reach for an Ochd (4HP, 32mm) for skiff duties at twice the price for twice the outputs in a third of the space.

Efficiency on the wallet is compelling but I got mine, I'm down the hole, I don't need cheap modules to tempt or help me to get up and running. However the suite of cheap euro clones that don't fit into one of the big 3 systems is starting to look like a great gateway drug to the big boy modular companies where innovation happens. Brains, Abacus, 4LFO, 4Play, Mix, and Space FX total a little over $600. Add a filter like their 121 Dual VCF and you have substantial power under your fingers for USD$724. That level of buy-in could inspire a lot more artists to give modular a shot, anecdotally I sure wouldn't have plopped down $2000 for a Moog if not for the B2600, and here I am balls-deep in even more expensive synths because of that Gray Meanie.
ModularGrid Rack

I don't think this counts as IP theft either unless Behringer decompiled XAOC's code which wouldn't be necessary for something of this complexity. This is a quad LFO module, pretty far removed from some unique and magical DSP-based products, and just knowing the basic functionality of Batumi you could replicate it with some textbooks and time. What is the element of Batumi that makes this an infringement - what is their intellectual property at risk here? How many VCOs or EGs are functionally identical with a different coat of paint? It's sad how quickly I see people run to "the law" in an effort to enforce their personal moral or ethical perspective when it's one German in particular. This is no counterfeit product wrt trademark theft: different looks, name, decorative symbols, logo. No one is confusing this for the XAOC original by mistake; the Four LFO is derivative but not counterfeit, or is it time to re-litigate the "your guitar body shape looks like my guitar body shape" issue? It seems like Behringer is operating within the bounds of "the law" that you want to use as a cudgel to beat them with, shucks, maybe grievances at this company are misdirected. If you find it morally repugnant then please lobby for the law to change rather than bleat onto the internet, it's a very sad "man shakes fist at cloud" situation to observe. Just FYI - anyone can report IP theft to the appropriate agencies and you don't need to be the owner of said IP to do so, just seeing it occur is enough. Go for it and post the results please, I'm not being facetious, we wanna know the outcome!

I'd much rather get some unique modules out of them and at this point I wonder if they're aping "tried and true" products to test the waters to see whether modular development is worth the full-time investment after the Roland100/Model 55/ARP2500 stuff. Behringer seems to have started slow and built up steam once the sales rolled in with their desktop/keyboard synth offerings, makes me wonder, but then again we're seeing more clones rather than releases in the same vein as DeepMind in that arena (and to be fair, originals will take longer than eyeing a template). This current batch could also be products that largely function for the company as advertisements for open positions, I think they've been seeking devs and designers for awhile now. It's not like euro fever is slowing down (though a depression may force it) so imo it's time to shit or get off the pot. Rehashes bore the fuck out of me from any company. Behringer's unique weapon as a company is extreme efficiency of margins, I'm seriously waiting for the "look at everything we could afford to slap together" Frankenstein's Monster that's too ugly, strange, and crazy to resist. Popular Module #69 doesn't tingle the peepee much to someone already entrenched.

I recently bought a Batumi but will definitely get one of those, maybe two, could never afford that at 360 instead of 99
Also never was interested in Maths but will probably give it a try at this price. Also own a couple of expensive Make Noise modules.


Also note: the original Batumi takes +45mA from +12V and only 15mA from -12V. This ripoff takes more than twice of that.


should be named in this way: "FOUL LFO"....


HGsynth thanks for the reply. This already helps a lot. Worth of mentioning is that i'm using a beatstep pro as wel to clock everything and as a sequencer. I was thinking about Pamela's new workout, or a extra vca from intelijel. What kind of multi-fuction tool do i have to think of?

My pleasure. Putting together a system without having tried all the modules is tough, particularly if you're new to this. Glad to help.

Ok, BSP is a fine choice. I love both my Pam's (I have "New Workout," haven't tried the "Pro") and my Intellijel quad VCA; both massively changed how I used my system. Also, the Pam's brings us back to utilities, because you should consider what you want to do with the clock from Pam's. How will you mult the boring regular pulses from one output so you can make use of Pam's more interesting features in the others, like euclidean rhythms, logic, quantization, or smooth random? Do you want to be able to multiply or divide the clock to send different speeds of the signal around your system? Do you want to use the gates as envelopes?
Clock dividers or multipliers (e.g, 4ms QCD), buffered mults (e.g., Joranalogue Link2), VCAs (so many different ones), attenuators/attenuverters/inverters (e.g., Happy Nerding 3xMIA, Frap 321, etc.), and slew (e.g., Joranalogue Contour 1, Doepfer A-171, etc.) all seem to make more sense when you think about it that way.

Other utilities, like window comparators, logic, precision adders, S/H or T/H, gate-trigger converters, etc. all are harder to conceptualize until you need one while patching. For example, what if I wanted to pick gates off of two related LFOs whenever their voltages reach a certain range? Or I want to make a step sequence from a complex LFO or smooth random voltages? Or what if one of my modules is not reacting properly to a gate because it only like triggers or the voltage is not high enough? All situations I've come across, leading to getting the utilities above.

For a multi-tool, I think Ornament and Crime is a complete game-changer. It's menu-diving is only 2 steps deep, and it has so many tools on it (personally, I prefer the Hemispheres option). Play around with that for a while and you'll get to know what utilities you need. People also love the Disting EX and MK4, but I haven't tried those personally. The EX is on my to get list, though. I recommend watching some videos about the different utilities to figure them out. There are a lot of good ones: Divkid, loopop, mylarmelodies, red means recordings, etc... so many great folks in the community explaining how modules work and giving patching ideas. I always watch a ton of those before making a purchase.

Good luck!

Forgetting utilities, modulation sources, etc. is a very common mistake at the beginning. When we think about our dream house, we are mainly focused on the living room, the bedrooms, the kitchen, the bathroom... Corridors, doors, staircases and closets are less of a dream.

@Sweelinck, I love this analogy. Definitely using it in the future. Thanks!

I can only recommend here modules that I use and appreciate:
Buff Mult (buffered multiple), A-180-2 (passive multiple), Sinc Defero (buffered quad attenuator), A-160-2 (clock/trigger divider), A-151 (sequential switch), CalTrans (calibrator and transposer), Booster Stage (amplifier to eurorack systems), Mutes (multi channel mute), Disting mk4 (multifunction module), Listen IO (input/output interface)...

Two thoughts.

1) You have a lot of nice modules here, and I wouldn't necessarily drop anything that you already have. But I would say that you're missing the architecture necessary to actually use a lot of the modules: utilities. You should be thinking about how to actually get signals to the modules and how you'll morph the signals along the way. For example, you have Batumi for LFOs. Awesome choice, but how are you gonna tame the signal without wasting Maths? Maybe an attenuator (or better yet, attenuverter) or two would help. Or, of course, you could have more VCAs. A sample and hold or track and hold might be worth considering for turning those random voltages into step sequences. A quantizer would be cool, too. What if you want to route a signal to multiple locations? Buffered mults will allow that without any drop in voltage. I particularly like the Doepfer Switched Multiples and Sequential switch for these purposes. There are many utilities that will allow you to mangle, tame, move, or manipulate the signal; don't forget about them! Maybe check out a multi-function tool or VCV rack to get a sense of which utilities you'll need.

2) How are you connecting to the outside world? Are you working with a computer or DAW, or just the standalone modular synth?

Best of luck!

Hi all,

As a fun challenge, I wanted to see if I could build a semi-generative system in small rack. So, using a Rackbrute 6U and modules I already own, I present the results. I explain my thinking below. But what about you? What's the tightest/most complete instrument you could build in a Rackbrute using only modules you already own? Any style, but please explain your rack.

So, here's my thinking:
Row 1: power, clocking, routing/mults, uO_C, voices, envelopes, VCAs
Row 2: modulators, gates, s/h, routing, triggers, VCA, effects, and end of chain processing.

Pam's runs the show with the master clock, with some utilitarian architecture afterwards to get the signals around. My main modulators are Batumi and Ochd, but there are other LFOs and modulators around, as well. Random gates, triggers, and sequences can come from several sources: uO_C, Pam's, or a combo of utilities. These get quantized by uO_C, which then feeds Plaits and Rings. Zadar helps shape it all alongside Veils. Then, the signals make their way to the end of the chain with some effects and sound shaping along the way. Finally, to cheat, there is the ES-9, making the exercise kind of irrelevant, but fun nonetheless.

So, let's see your racks.
