Hi Lugia and Ronin,

Thanks for your help and for all the information. I looked at replacing the 8 HP mixer with the Happy Nerding 6 HP one, but there still wasn't quite enough room for the Nebulae on the bottom. I was racking my brain, so to speak, and had a very unoriginal idea: adding more space. With a third, separate rack in front (Pittsburgh Cell DC with +12V 900mA), I'd have plenty of power for the ER-301 and the Catalyst, and could also play it separately from the rest of the rack: on the couch or at a cafe, or possibly even on a couch at a cafe.

With the top two rows, I added the Magneto and two Xaoc modules. The total +12V consumption for those two rows, (with the Nebulae on 5V) is 727mA, which seems to be sufficiently safe.

But is it too safe? I mean, from a sampling/sound design perspective? I realize this is much more subjective territory, but the Magneto is taking up a lot of real estate, relatively. And while I love the look of the two Xaoc modules together, and the potential for slow and evolving modulation, maybe I could replace one of them with something more wild and/or crazy? As for digital vs. analog modules, this rack seems to be on the extreme digital end, which I don't mind if it's not distractingly noisy.

I had planned on just getting the ER-301 and the ES-8 to play around with Mutable stuff on VCV Rack, but now I'm in full modular avarice mode. Realistically, there are going to be gaps on the rack while I try to make up my mind and get good deals. The ER-301 is the one module I'm married to, and which will hopefully arrive next month. The Catalyst and Expert Sleepers stuff has been ordered. The rest, except for the headphone out, is still mostly up in the air.

Thanks again for your help.



Thanks for your insight Lugia..
Really appreciate your constructive criticism and I'm not that proud to admit that I really liked how all these black and gold panels look together; but was often frustrated when patching as there was always something missing..

On to your points:

1) More VCAs (I have the 132-3s I could use and maybe get another Veils down the road as I like how clean it is)
2) Ditch Shelves and Rings; use Ripples and Wasp VCF for EQing/shaping sounds (gain some space for properly expanding)
Maybe ditch Edges too and build its 10hp version or just see if I'm missing anything.
3)I actually do have attenuverters from Blinds so I could maybe get some more (maths?!)
4) I like A-171-2 and plan to mod it for it to be more usable; maybe incorporate it to my main rack
5) no idea about the expert sleepers stuff; never used any of their modules but may need to take a closer look.
This may help to incorporate the modular in a hybrid setup more easily.
Could you please be more specific about utilities that you like/use ?
CV processing utilities, trigger generators etc?

Well, first off...it's really...ah...BLACK. But that's not good. Invariably, if you're creating a Eurorack along a certain look, then all you'll wind up with is a decorative prop. You've done a little bit better than that, but at the same time there's weird flaws here. A 4 x 84 rig with only four VCAs is definitely a flaw...especially if you're trying to do lots of percussive work, because you need LOTS of VCAs for that sort of thing unless you're using percussion-specific modules (Tiptop et al).

The MIDI implementation is frankly lousy. You're running two of these mBranes to get 8 channels; why not dump BOTH and go with something from Expert Sleepers that fits in a similar space but which can be expanded AND provide a return channel for timing, digital audio return, etc?

There's an Elements...and a Rings? OK with the Department of Redundancy Department, perhaps, but a waste of space otherwise. Lose one or the other.

I could go on, but really, I think you've poured waaaaay too much effort into creating the synth version of the 2001 Monolith here and not enough in basic, practical modular design. All of these Mutable and clone modules might look awesome, but by ignoring very basic, boring-as-hell utilities and basic practicalities in favor of optics, well, it's a nice prop, and you'll continue to be frustrated. For example, your modulation source issue...you actually DO have ample modulation here, but because you've omitted utility stuff such as attenuverters or CV/mod VCAs, it seems like there's not enough when the real fact is you've just not got ways to implement what you have already. And having some of these huge, sexy modules means you're ignoring much better options in your "junk" rack; for example, I would think that using the Doepfer Wasp and Yusynth Synthacon VCFs would provide way more timbral character than the two resonant filters on the Shelves. And so on.

Musical instruments might seem like a fashion statement, but consider: is it important that Ornette Coleman plays a plastic sax, or is it more important that it's Ornette playing said plastic sax? Don't worry about looks...but be a lot more concerned about the music.

Unusable. This contains no VCAs whatsoever. No proper envelope gens, either. Lots of snarrrrrrrzy modules there...but none of the ones needed to make this work. Small builds require smaller modules, and this one's got only one (Manhattan's CP3 clone). And if you've gone to the trouble of cramming 4ms's STS in there, why isn't the final mixer stereo? Or at least, why no stereo output?

Two options, both beginning with scrapping this build and starting over...

1) Start with a larger cab. If you want to use these honkin' big modules, well, bigger = more hp needed. Plus, if you want to use these honkin' big modules (notice I keep dinging on that point where this smaller build is concerned), you will need more space (as in twice as much, most likely) for the necessary modules you've omitted as well as other modules that will make this much easier to use. Seriously. Try assembling something like your original in VCV Rack and see how UNsatisfying it is to use a synth with next to zero control capabilities.

2) Start with a larger cab (again...yes, there's a pattern there), but only somewhat larger. Then scrap ALL of these big modules and try and reduce your panel sizes to something that makes more sense in a smaller build.

Actually, your best bet is to do both. But before that, get a copy of VCV Rack and examine why all of these "boring" modules are actually 100% necessary, and then spend some time studying other experienced builders' MG rigs. From both exercises, you'll notice a pattern that emerges regarding necessary modules, module combinations, setup and signal flow, and so on. But at the very least, do not drop a pile of $$$ on the above build. I can guarantee that you'll be extremely disappointed if you do.

I'm about to finish my current 12U setup but often feel that I need more modulation and that I have more noise sources that I can use effectively.
This is a general duty rack but mostly oriented to drum duties maybe a synth line too and is supposed to be used along a machinedrum and a laptop running Ableton Live..
I was hoping to get into generative drum/percussion style patches to make things more interesting but probably need more probability modules and trigger generators so for now I'm just focusing on extra modulation.
I frequently patch it on its own and I seem to exhaust the modulators and VCAs pretty quickly so was thinking the following:
Get rid of Braids and Edges and replace them with NLC sloths, a second micro O&C and maybe a second Veils.
Another plan is to get the second O&C and a Pam's workout and start from there..
I could probably put aside Rings too since I'm not using it that much although it's nice for some additional bleeps.
Without Rings, Braids and Edges I think I could have a lot of space for extra modulation and maybe some more triggering options..
Any suggestions are welcome since I think I'm a bit stuck at this point.!
ModularGrid Rack

I also have a second rack in the making which temporarily serves as a storage rack for the modules I don't currently use a lot.
ModularGrid Rack
I could probably mix and match some modules between these 2racks if anyone has any ideas..Obvious choice would be the terminal tedium but I haven't finished it yet:P

Just received the TiNRS Wobbler module from @nosp. Communication was friendly, shipping fast and the condition of the module is very good. Thanks!

Hello everyone,

Thinking of my first Eurorack. I'm looking for a little system composed by long life and good sounding modules (that's why I chose Synthesis Technology). I want to experiment with clock sources/melodies and see whats goin on.

What do you think? Am I missing something?

Looking for your suggestions, thanks in advance!

Hi Lugia, Ronin, All,

Coming back to this post regarding above mentioned Behringer & Arp Odyssey, the Behringer K-2 and a little on ASM Hydrysynth (desktop model).

Beginning of this week I had the opportunity to get to my local dealer and voila! There it was the Behringer Odyssey and the K-2, ready to test. I didn't had too much time but I had some quick looks and a short test on each of them. Here are my impressions:

Behringer Odyssey, well let's start again with the Arp Odyssey, personally I wasn't too impressed by it (scroll above to my post of the 1st of September). This time I tested the just new Behringer Odyssey. What a difference with the (new) Arp Odyssey! In a good way this time!

Let me start with the touch and feel of it, which is good, the switches are good to use and the (LED) sliders are quite nice to use too. The housing is made like a tank, there is pretty thick sheet- or plate-metal used and that's rock solid. I tried to lift up the Odyssey. The good news is that is possible but you can feel the heavy weight. For people who want to take it under their arm with them, it might be not so ideal but I actually like that kind of "build like a tank" feeling :-)

Then the sound, wow yes, that's some serious old, "fat" synthesizer sound, personally I like that. When I compare this one with the lately Arp Odyssey, I would definitely go for the Behringer edition and not Arp; sorry Arp. Here in Europe at Euro 449 it isn't too cheap (however compared to Arp it is) but for the fact that you get a "solid tank" with a good sound and switches and sliders that are nice to use, it might be worth it. Personally, the Odyssey is too deep for the space I have available left, so I have to let it go for the moment but will keep an eye on it. If there is ever a good special offer for it, I still might decide to get one.

Then the K-2... I got already the Neutron from Behringer and I am actually very positive about the Neutron. So when I tested the K-2 I just couldn't believe it... in my opinion the K-2 is beating the Neutron, it's beating it with ease! My goodness, what a lovely little synthesizer that is. Now I don't know the original Korg MS-20 (because that's what the K-2 is, a kind of replica of it) sound but this K-2 has a sound that's beyond believing (for that price) and that puts the Neutron easily in its shadow.

If the Behringer Odyssey sound was kind of old fashion, nice, fat, sound, the K-2 doesn't sound "as fat" as the Odyssey but it has its own characteristic of sound that's, at least for me, close to unbeatable, what a lovely sound.

Then the touch & feel, for the housing that's very similar to the Neutron (and the Model D), however the knobs of the K-2, somehow I feel they are even better than the Neutron, or at least very similar/good as the Neutron.

So I definitely will consider the K-2, most likely I am going for that one. The only issue is... what would be a good and available(!) Eurorack convertor module to be used with the K-2 to make it Eurorack compatible? I think we started that discussion about the convertor module already earlier in this thread (somewhere up here) but if I remember well we didn't found an available module yet that would be suitable. Or is there an available convertor module that does?

Then I spoke with my contact at my local dealer about the ASM Hydrasynth, not sure when that becomes available, let's hope in December but that seems not to be sure; at least not here in Europe. This guy I spoke with had tested for just a very short while the ASM Hydrasynth desktop variant and he was very impressed about it. It seemed to be build good, the synthesizer seems to offer a good deal. The only con he could find in the limited time he had was the limited number of available preset sounds. So I can't wait for the Hydrasynth to arrive in Europe and to have it tested.

Wish you all a good weekend and kind regards, Garfield.

Hi Ronin,

Skiff? I don't have that, at least not yet, my desk is pretty full with some Doepfer A-100 casings. I might consider a double Intellijel 7U case because I am recently a lot away from home and don't have much time left to play with my modular system (when I am back home) but I put that "traveling case" on hold till next year and then will check if I want really a traveling case or not. Let's see.

Oh that's good, that the Rubicon 2 got an LFO that can go quite slow, sounds good too :-)

Kind regards, Garfield.

Hi Danjas,

Regarding point 1, not sure but maybe the ACL Sinfonion can do this, you might want to check that module out. The con is the price.

About point 2 not too sure what you want, do you mean something like a random generator or something like that? If yes, there are several random generator modules, just go in this forum at modules and look there for what you might need.

Kind regards, Garfield Modular.

Thread: MyCase

Reading glasses. I've given in to my age and I use them when I need them. It's best to just leave a pair of readers next to your set-up. I found a pair of fold-up glasses that fit into a case the size of an oversized cigarette lighter. I keep them in my pocket.

The next issue for older eyes would be proper lighting. I love a dimly lit room when I'm being creative. But dim light makes seeing tiny print even harder. For this, I have tree solutions. I placed a large lamp in my music room. I also have a desktop lamp with a gooseneck. The third thing is having a USB charging port connected to the 5v rails in each of my 3 cases (Intellijel). I can then use USB gooseneck reading lamps in my case. But you'll want to check if they inject noise into your signal and pull them before recording.

For rhythmic complexity... I like Euclidean generators. I won't explain them here, but you can find several modules capable of generating them either as dedicated modules or a function within... like the Temps Utile module. I'm also considering buying a second hand Trigger Riot after watching a few videos on it. I really like the idea of creating rhythms by indirectly influencing a parameter than simply just programming them by hand. You can get pretty wild by patching from one Euclidean generator to another, throw in a logic module, and possibly triggering a reset periodically. You can also use/misuse clock dividers to great effect in the chain somewhere. You can also literally mix gates/triggers together at low volume and where they align you'll get a legit trigger (devices like logic modules want to see a minimum voltage to count a signal as being true, so they are great to add to the end of the analog summing to make sure you get clean gates/triggers).

ha. didn't even know this was a forum, thought it was like "notes". lol. deleted

Hi Lugia,

Thanks for your detailed reply. Unfortunately, it's not what I wanted to hear, so I demand a retraction. How dare you lecture me about some made up "rules" after I put my heart and soul into that theoretical rack?

No, seriously, thank you. Is there a downside to powering the Nebulae with 5V other than needing to keep a separate tally of the power usage? According the the ER-301's website, its peak current is 250 12V+ rather than the 300 listed on MG, which would bring the 12V+ total down to 772. I understand that the consumption listings in MG shouldn't be taken as gospel, but it seems I'm painfully close to being able to safely power this little rack with the supplied power. And I admit, just aesthetically, I'd rather not have two separate "on" switches, even if - especially if - one isn't being used.

But I'm prepared to hear what I don't want to hear.

Thank you,

Hi Tyson,

I'm going to include some info that's loosely related to your posts and some that's more on target.

Some modules offer alternative powering solutions and set-ups. For example, modules with vacuum tubes in them may require additional power supplies because of the huge draw from tubes at start-up. Erica has a vacuum tube series that requires a separate "tube warmer" power supply for start-up. I believe they may have solved the issue for later models in the series. But if you see a tube in your gear... you really want to focus on start-up voltage draws. What Lugia said is important.

Digital modules are noisy. It's just a fact of life; especially with modules with display screens. Digital modules are also built to different specifications depending on the builder. You might find people putting digital modules in a separate case or in a corner of their case away from modules that might be more sensitive. Some modules, like those from Noise Engineering, have a toggle switch on the back that allows them to be powered from the 5v bus in order to improve interference.

If you hear the term "passive" it means the module requires no power. A passive mult or a simple attenuator would be examples. Some will work passively, but have "active" portions. The Noise Engineering "Mutis Jovis" is passive four channel mute module, for example. It works passively. But if you plug it in, the LEDs indicating signal level will work.

Hope the information is helpful in some part.

Hey. My advice:

Delete this post and reformulate it towards your end goal. Post a link to the proposed rack. I realize that this rack will evolve and change as your building it. But there might be some advice that spurs you to make additional tweaks or changes along the way.

Also, take a look at some of the feedback on others racks and take not of the criticisms and why they may or may not be valid.

Looks like a nice list of modules cherry-picked into a rack.

If you wanted to change the polarity of a CV signal... how would you do that with THIS rack?
If you wanted to scale a CV signal, mix two CV signals... again... how would you?

I don't see any traditional ADSRs. Why not?
The Batumi can always use the Poti expander. In a large set-up, it's very much worth the 3HP.
The only dedicated effect is a Chronoblob... if you're doing ambient, where is your reverb?

All in all, this looks like a fantasy build that has very little study behind it. Sorry to be so harsh. But if someone else putting together a rack sees this they should take these comments to heart.

The Rubicon 2 makes sense for a mature rig. For a skiff... I wouldn't think so as getting a nice palette of modulation sources out of skiff would be a bit difficult (sources, attenuation, attenuverting, etc.).

I've managed to get some sounds out of it that put it in league with some of the coarser sounding Noise Engineering stuff. ALSO... it has an LFO mode that can go pretty slow. So you can use it as a source for complex modulation of other oscillators/filters etc.

For me, the value is there due to its usefulness. But the cost rises proportionally. :)

Thank you! It works perfectly for me, let's see what others say. I understand that it's useful to be able to have 1U/3U/all option as a drop-down, but it got a bit frustrating to have to change that part back to full size every time.

Many thanks!

All rights reserved, all wrongs reversed.

I liked how 1U was hidden unless you turned on that radio button

1U manufacturers hated that function.

but now whenever I hit Reset I get to see all the 1U modules in there. Would it be possible that the Reset also retains/remembers the last Height selected?

It breaks the expected behaviour of what a reset does but in this case it seems like a good idea, so now it works like you suggested.

Or am I just being weird?

That is a complete unrelated question!

Currently it's not possible to add the power consumption of Series 500 modules like we do it with Eurorack systems.
That should be improved. The goal is, that it should be possible to calculate the power requirements of all modules that are added to an enclosing/rack so it would be easy to verify that a power supply is sufficient.
We missed to collect power data for Series 500 modules so that must be added at first.
I am not so deep into electronics so I need some help:

I have read in the 500 Module Series Spec that a bus connector delivers +16, -16 and +48V.

That matches with the API lunchbox that has three LEDs, labeled with +16, -16 and +48V.

I guess these basic assumptions are correct:

  • Every 500 Series compatible enclosing has a power supply that delivers +16V, -16V and +48V.
  • To calculate the power consumption of the system, all three values of all modules must be summed separately.

But I am not quite sure how that matches with the spec of e.g. the API 512c module.

512C has a switch for 48v phantom power but the spec only says:
Power Consumption: ±12/18 Volts/DC, @40 ma.

That mismatches with the 16V spec.
1. How should user enter this data into the database?
2. Can those values be converted to 16V?
3. Do we need additional fields in the database?


  1. I need a module that could change the incoming cv sequence. For example, i have the sequencer playing some notes, and i want to play with this sequence - change this notes to a different order, to the another speed or another speed between each note.
    So maybe does such module exist?

  2. And another one i need to generate bleeps and glitches from the incoming signal. From example, i have a patch of pad and i want some module to generate bleeps, glitches, some effects based on that incoming pad.
    Can you guess any eurorack module for this purposes?


Hm, am I the only one that gets irritated that the default search function has All Sizes included? I liked how 1U was hidden unless you turned on that radio button but now whenever I hit Reset I get to see all the 1U modules in there. Would it be possible that the Reset also retains/remembers the last Height selected? It does remember the radio button statutes.

Or am I just being weird?

All rights reserved, all wrongs reversed.

Hi Nniikkoo (Niko? :-) ) and Ronin,

Nniikkoo/Niko, thanks a lot, I definitely will consider the E330, though I don't have a dealer where I can test it, but it's on my list :-)

Ronin, thanks a lot for your information. Yes I thought already it would be something like that but it's good you had confirmed that in details. So looks like I have to go for the Rubicon 2 then, instead of the Dixie 2+ :-) I will change in my wish list the priority of Dixie 2+ (lower the prio) and prefer in my list the Rubicon 2 (higher prio).

I got the Doepfer A-110-4, it's a more simple VCO but also has this "through zero" capabilities, fantastic what you can do with that, so since the Rubicon 2 got that capability as well, I am really thinking of that Rubicon 2 now (instead of Dixie 2+); it's just the budget ;-) But yes, you are right, it's worth it to go that extra mile (i.e. extend the budget) and go for the Rubicon 2 instead.

Thanks a lot and kind regards, Garfield.

Hi Ikke1996,

To be honest, I do think you need to get more experience with the Neutron. The more experience you get with it, you will start to feel what you might miss on the Neutron and that might translate into what you might want to consider to look at it in modular. If I may say it like this: "I don't think you are "ripe" (i.e. ready) yet for modular" ;-)

So build up more experience, while doing that you can check things like check your budget, what are you willing to spend on modular (do realise that it can costs several thousands and that's just for the beginning of it). Check the size of your planned modular case, choose a size that can hold for the future too, not that after a few months or something you need another case. So think in terms of at least 2x104 HP (Intellijel 7U case for example) or 3x84 HP cases (Doepfer A-100 for example) as a real minimum, better is to think bigger. Meanwhile still building up experience with the Neutron.

You also can check for yourself how happy are you with components of Neutron like:

Oscillators (VCOs)
Envelopes (EGs)
Filters (VCFs)
Audio input/output interfaces for modular

Check component by component what's important for you? How should it work, what should it give you? You can check the basics with the Neutron, try to create an opinion for yourself with that for each component. Once you got that, you can answer easier your above questions by yourself. Don't get me wrong, it's not that I don't want to help you but the best learning curve is if you are going to figure that out for yourself. That requires experience and with that you can easier build an opinion for yourself what you want from each component and from modular in general.

This might sound dull but it really helps is to read the posts in the Racks part of the forum. Don't read the first few lines but read the entire posts to understand why people give certain advices. Start to read with the post that's called "Why your 6U x 84 generative rig won't work" post, that covers most of the starting issues, after that some other posts in the same section (Racks) of this forum.

Modular is not only about making music with it, it's in the beginning a hell of a job to start reading into it, learning about its components and its basic understandings, then the planning, investigations that are required for that planning. And then, and only then, perhaps then start think about buying a modular case. Not straight away fill it up fully, no keep it about half empty. Start with getting experience with the basic components, build up again more experience, adjust your opinion again on the gained experience and then check again what you might require. It's a long road to go (if you don't want to waste money like hell), but a very nice way to go if you are really into modular.

Oh by the way, and also be prepared to learn from mistakes, that's pretty common in modular too ;-) I mean to make mistakes, as long as you see that positively and take that as a lesson learnt, then that's fine.

I hope this helps a bit for starters and kind regards, Garfield Modular.

Thread: MyCase

OK...after checking the edit above and the PM, some suggestions...

First up, given your sight issues, I wouldn't lose the Elements. That's a very useful device, inasmuch as you have the modelling generator and the resonator (aka Rings) in one package here, and it's bigger and clearer to use than the 3rd party builds. The Contour should definitely stay as well...not only does it have the ability to work as four AD envelopes, you can loop these and use each section as an LFO with CV-controllable rise and fall. And the Penrose quantizer + dual S&H actually give you the rudiments of an analog shift register, so those need to be there. Basically, the module compliment (aside of the DATA) is fine...you just need to fill the hole with the right toys.

If you need the larger panel space (yeah...my near vision is totally shot, too) for VCAs, your best bet is probably Intellijel's Quad VCA. Basically the same thing as the Mutable Veils, $10 cheaper. Then you can use the Blinds as a quad CVable attenuverter, which should really help that OTA VCF sing as you can then feed it inverse envelopes and/or complex mixed modulation. As for a second filter, try something more exotic; the OTA VCF has your basics covered. Maybe Dave Rossum's Linnaeus would be a good fit there.

As for the next 104 hp you're thinking about, consider dedicating that largely to sequencing and timing. The quant setup there could make use of a good sequencer, which also means a decent clock and clock-mod setup. Definitely consider adding some logic gates at that point; logic + things like comparators, skippers, divide/multipliers, etc add lots of potential rhythmic complexity. As for which sequencer, that depends more on the sort of music you tend to create, as some sequencers do certain things better than others.

Did some checking, and the VRL cab's 5V line has 1A available. My concern was that the Nebulae v2 would draw too much for that, but Qu-bit's own data shows it as having a draw of 47 mA on +12, 7 mA on -12, and 271 mA on the 5V bus. If you can get your +12V bus draw down to 700 mA-ish, you should be in the right current ballpark. But again, check the manufacturer websites for the data here, since everything's getting close to those P/S limits.

The other thing I'd consider changing would be the mixer. A better choice would actually be the Happy Nerding 3x Stereo Mixer, I think...while it draws more than the JPSynth one and has one less stereo input, it's also 2 hp smaller and because it has an onboard TRS out that can be used for headphones, it eliminates the need for the HPO, and that opens up another 2 hp. The Nebulae should then fit into the space occupied by the Catalyst (move that to the other row), and this puts your free 4 hp in the other row for use by another module.

Hi Lugia,

Thanks for your detailed reply. Unfortunately, it's not what I wanted to hear, so I demand a retraction. How dare you lecture me about some made up "rules" after I put my heart and soul into that theoretical rack?

Thread: MyCase

First up, unless you have a Clouds onhand, you can delete that module as it's been discontinued for quite some time now. Not a bad thing, actually, as you could go with a 3rd-party build that'll be a lot smaller.

Mordax's DATA...hm...I sort of think it's more of a toy, eye-candy. Consider: how much do you need the o-scope and FFT analyzer functions? The other things it does, you either have already (Octocontroller, which handles all of the DATA's timing tricks and then some) or would do better getting in individual modules (the VCO capabilities). Remember: this is a very space-limited build, and the smaller you can make everything (within reason) the more functionality you can cram in. So that would also preclude losing the Elements and Blinds as well and also going with 3rd-party builds of those in order to save panel space.

VCAs? Yeah...this thing desperately needs them. Codex Modulex's version of the Mutable Veils would be a good pick. Right now, this doesn't have any proper VCAs at all, and that's a pretty serious problem as it leaves you incapable of controlling audio and/or CV/mod levels with your modulation sources.

As for the rest...get the initial build here reconfigured with smaller versions of the Mutable stuff, lose the Clouds and probably the DATA, then it'll be easier to see where to take things.

Thanks @Powlow for the great Winter Modular Eloquencer. Quick delivery and well packed!
I recommend him as a seller.

Is the data sheet summary available for pedal board and 500 series effects?

no, it's not available.
For reasons I cannot remember we did not collect the power data for 500 series modules.
We have power data for pedals, but the data sheet has to work different because of the different possible voltages and the fact that the pedalboards don't have the concept of rows.
Both issues can be addressed, though.

Thank you again for all the work, I plan to support site for a long time.

I would be grateful to get some advice on my rack. This rack is for real though, and not a plan. What should I get next. Utilities probably, but what to prioritize?
A slew limiter, another mixer, (like the Endoprhin.es Cockpit that I can get rather cheap), a mixer for CV, another filter and or a LPG, a "proper" VCA, mults, (yes definitely mults), a sequential switch? What do you think?

I got two Mother 32's and a Dreadbox Nyx + a Zoma Lyra 8 and pedals that I use with this rack.


Rule #1: never assume that the MG amperage figures are correct. ALWAYS overestimate your current needs.

Rule #2: Since there's a spike in current draws when you turn a device on, even if your operating current is 822 mA, that doesn't mean your inrush current is also 822 mA. And it only takes a fraction of a second for certain components in an overtaxed power supply to go "pop!".

Rule #3: When speccing power supply current figures, take your MG module amperage sum, then add 1/3rd as much more to that figure. Then add more besides that. You DO NOT want to push a power supply; instead, you want that power supply to loaf along like its not got much to do. This adds up as lower operating temps in the case, more stability across the system, and less component stress.

So, given the 1140 mA figure (I don't recommend using 5V unless necessary...keep things simple), you really need something with about 1.5A to get bulletproof operation. 1A with that = BOOM! or something similarly unpleasant along those lines. And if you do go the 5V route, you're still not 100% guaranteed that that'll work...1.25A for 822 mA is more sensible.


I'm looking to build my first rack, mainly for sample manipulation and integration with VCV Rack. The ER-301 would be the main sound source along with the Nebulae. The Catalyst looks fun for Octatrack-style crossfading between parameters. I have a Pyramid and Bitwig for sequencing and additional modulation, and a MIDI controller via the FH-2 for more knobs.

Any glaring omissions or missteps? More subtle problems? I know more VCAs is kind of a mantra, but I'm hoping that the ER-301, VCV Rack, and even Disting could fill that role - along with filters and everything else - while I'm getting my feet wet.

My main concern is power: I have the Pittsburgh Lifeforms Research Console, which has 1 Amp +12V, -12V, and +5V. The MG planner shows a power consumption of 1140 mA +12V / 183 mA -12V, but the Nebulae can run on 5V, which brings it down to 822 mA +12V / 176 mA -12V. Am I calculating that correctly and being conservative enough?

I'm not entirely sure I know what I'm doing, but am reading up, trying the put together something modest with lots of learning potential, and hoping not to electrocute myself. Any advice would be greatly appreciated.

Thank you,



The Dixie II+ is a basic VCO. It really doesn't do much more than any other basic oscillator. It has a sub oscillator, which is a nice feature if you make a lot of bass sounds or a sub factors into the sound of your patch (not always bass).

The Rubicon 2 is more of a complex oscillator due to its "through zero" capabilities among other features. You'll also see that reflected in the price. You can substitute the Rubicon for a Dixie... but not the other way around if you start diving deep into features.

I have the Rubicon 2 and I'm considering the Dixie as an additional VCO... I have a Z3000 but prefer the workflow of the Intellijel stuff.

Obviously #1 is doing nothing

Thanks to @netr for a nice transaction.

Admittedly I'm impressed you are all so willing to put the effort. I won't get into the nitty gritty of the matter, but I do feel impressed about how strongly some people feel about helping newcomers to the format of modular.

There's a lot that can go wrong with modular. Not the hardware, mind you, but the user. It is ridiculously easy to get all bug-eyed when viewing MG and then conceive of a Deadmau5-level wall of blinkenlichts und tvistenknobs that appears like it might be a badass synth rig...until you blow $20k on it and realize that what you've created is an unworkable mess.

And a lot of us just don't like seeing that happen. Modular synthesizers have loads of possibilities as long as they're not thwarted by bad planning. But given that there's not really any decent books on modular synth architecture, and the Internet has a lot of really crappy info foisted off by people who know how to make a good presentation but who ultimately don't know jack-shit about the subject, about 80-90% of the info I at least run across (other than that by manufacturers and/or most retailers) is utter rubbish. And that doesn't help at all...in fact, it more or less UNhelps, leading to systems sitting in closets and so forth when they should be out making wonderful noises.

Ultimately, I think those of us trying to put this effort forward are simply wanting people to make music, and to make it with instruments that work and that are a joy to play.

A switch isn't a mult.

-- Ronin1973

Yes, you are correct. If you are seeing what I am seeing, there are switches all up in there. That's why I asked. I didnt say a switch was a mult.

This rig won't work. Period. You only have a VC8 as a mixer, which it can do but which isn't necessarily its best suit. Plus, the VC8 contains linear VCAs...not the best for audio, especially in the output mix stage, and you've got it way overtaxed with all of the signal sources in this. I see NO intermediate/submixers, NO attenuverters, NO adders, NO logic, NO buffered mults...there's "sexy module syndrome" all over the place here. If you've already bought all of this, congrats...you've built a Money Pit! I hope you haven't, though, because this is one hellaciously expensive fail if you did.

Utility modules are NOT an option. They're a necessity. Without them, you'll have a costly box of modules that really won't work well...or at all, tbh. Spend some time with VCV Rack, or checking out experienced builders' rigs here on MG, or studying "classic" modular systems from the past to see why they're "classics". You'll wind up saving a lot of time and, potentially, a lot of money that way.

Hi, thank you for the hard work into such a great site!
I am now using the site to organize my pedal board and 500 series effects, and I do not see the datasheet summary option like for Eurorack.
Is the data sheet summary available for pedal board and 500 series effects?
This feature would help with power capacity planning for new racks. Right now I am making a spreadsheet version separately to capture this information.
Thank you again for all the work, I plan to support site for a long time.

when I click on the link I get a different rack!!!

noob mistakes abound

these small cases are very expensive for each HP - get something 6u/104hp - a mantis for example (really good value) and space to grow into - without this you will just buy another case within a couple of months - or at least want to!!

and then go slowly - minimum viable synth - a sound source, a sound modifier, a modulation source (missing) and something to play it with and something to enable you to listen to it - add a disting mk4 - just so you can learn what different modules can do - if you constantly use the same algo, then buy that module and use disting for something else

and buy a quad cascading vca (veils or intellijel, for example) you will not regret it ever

after that only buy a module once you have learnt each module well and the rack as a whole well

BUT my advice is if you think that this is what you want from modular - get a mom32 or crave or something similar instead

there's no plumbing

by that I mean there's not enough utilities for half the modules there, let alone for the 23 modules that are there - matrix mixers/sequential switches/vcas/unity mixers/mults/lpgs/attenuators/attenuverters etc etc etc

they'll be much more useful in terms of getting the rack to gel as an instrument than adding an extra sequencer - and way cheaper too!

maybe show us what you've actually got...

Can we get the silver panel version added for this module?

Hi, so i recently bought a Behringer Neutron and now i’m looking into what to buy next.

My goal is to eventually create a dawless setup for (mostly) techno music. Something like the music of Momec: https://www.instagram.com/momecmusic/.

So my question is: what could/should be my next steps? What synths/modules can/should i definitely buy to eventually achieve my goal. I’m not necessarily looking for names of modules, but rather for what kind of modules, so i can do some research and look for the ones that fit me the most. Thanks

Admittedly I'm impressed you are all so willing to put the effort. I won't get into the nitty gritty of the matter, but I do feel impressed about how strongly some people feel about helping newcomers to the format of modular. I guess cleaning up MG isn't that dissimilar - so we're all a bit weird after all :)

I'd be happy to do some proofreading (it's part of my profession) if you need it.

Bought MN Tempi from @restlessboy. Quick delivery and well packed. Good seller. Recommended!

Hello Guys, just let me know what you think... This is a new setup with many new modules, under my discovery yet :!
