Oh my goodness. I've never heard of these but oh wow they seem useful. Thanks for teaching me something new today!

-- HGsynth

Essentially, these NKPs are just a collection of capacitors. Many bus boards already have similar components built in. I can’t say for sure if this is an effective solution for eliminating noise, but I assume it could help in certain configurations.

If you have any idea what it could be, I'd love to hear from you.
-- Hoggres

I don’t have a definitive solution, but I do have a few suggestions to consider:

Approach 1:

Unplug all modules from the power bus. Reconnect the modules one by one. This might help identify if a specific module is causing the noise. If you find the source, consider using a "Noise Killer Plug" on the problematic module: https://www.midi-hardware.com/?section=prod_info&product=NKP

Approach 2:

Take a loose wire and connect one end to the rail of your Eurorack and the other end to the casing of your other equipment (e.g., audio interface, amplifier) or any component involved in your audio signal chain.

Approach 3:

Start by simplifying your audio path to isolate the issue.

Begin with the simplest setup: Eurorack -> amplifier.
Gradually add components: Eurorack -> audio interface -> amplifier. Adapt this sequence based on your actual setup.

Approach 4:

Try using a different sound system. Take your rack to a friend’s place and test it there. If the noise is absent, there might be a device in your home setup (e.g., a refrigerator) causing interference. Rotating power plugs by 180 degrees might help (if your country uses reversible power plugs).

Personal Experience:

I have a "WMD Performance Mixer Mk1" that produced significant noise through my speakers. After connecting this module to a different power supply in my rack (I have eight Meanwell RT-65B units), the noise disappeared. Replacing the Meanwell RT-65B made no difference. This suggests that certain module combinations within the same power supply can create noise issues.

Good luck!

Finally circling back around here... This doesn't seem to be returning all of my modules. Are their other parameters for paging through, or a flag to dump everything?

As an ugly workaround you can open the javascript console of your browser and execute this snippet:

Hide modules that are not in the rack

$('.box-module').show(); $('.box-module:not(.in-rack)').hide();  

But be aware that this only applies to already displayed modules! So you may have to scroll down after clicking My modules

EDITED Aug 14th, 05:29

Does it make sense to lock module editing even when there is no information about module depth or 5V power consumption?
for example: https://modulargrid.net/e/winter-modular-eme-black

@modulargrid: consider to make those fields required before beeing able to set it to "Approved by manufacturer"

Power Supply (uZeus 4HP) specs:
+12V: 2000 mA
-12V: 500 mA
+5V: 170 mA

Doepfer basic VCO A-110-1 needs:
+12V: 90 mA
-12V: 20 mA
+5V: 0 mA

Moog Mavis needs:
+12V: 112 mA
-12V: 0 mA
+5V: 0 mA

you can simply sum up those numbers for each power line (+12V, -12V, +5V) and compare it with the numbers of your power supply. as a recommendation you should not exceed 75-80% of the given power supply

If those numbers are correct (please verify yourself) it is totally safe to use it for your 2 modules. Further you have a lot of headroom for more power hungry modules left...

When dealing with multiple browser windows for rearrangements all windows are doomed to use the same zoom level.
This is a bit tedious when dealing with one huge and one small rack.
As far as i know the browser zoom level is always the same for each (sub)domain.

@modulargrid can you try to add a 2nd subdomain which serves the same site (like www2.modulargrid.net ) to allow different zoom levels?
Or will this break the copy paste functionality?
In case you give it a try dont forget to set canonical meta tags and disable site indexing.

...I would apreciate a healthy discussion on this topic, do you have sync problems or is your system working...
-- GunnarWaage

Maybe a bit off topic because i dont use "sample accurate sync" but here is my synchronisation experience:
We have a lot of jam sessions with all kind of electronic music equipment (dozens or close to 100 different syncable devices within the last years).
Everything is synced via MIDI clock and in some subsystems this MIDI clock gets converted to CV-clock/reset via Arturia devices (Keystep PRO, Beatstep PRO) or PAMs.
In those hardware based setups sync accuracy has never been an issue.

As soon as a laptop or tablet (windows, mac, ios, android) needs to be synced as slave things start to get inaccurate.
But every better software has the possibility to adjust the clock-sync-offset in milliseconds.
Strange thing i experienced is that the needed offset value is often very different compared to former jam sessions with the same equipment.

There are indeed a few syncable eurorack modules that are always a single CV-clock-tick ahead.
To solve this issue i have built an arduino that holds back the very first clock tick after start.
Now i have 2 different master clocks in my eurorack to get everything in perfect sync

in case you have 2HP left it shouldn't be that hard to turn a blank panel into a non-destructive breakout module with a few small switches.
with long jumper cables it also would be possible to place this breakout module in the row above or below...

...patch cables go from input to output hence an optimised system should ideally have the same number of these, no matter which modules are included...
-- Dan_ogq

I disagree. for me an optimized system is defined by other aspects than than the relation of I/O's
- most important: can i achieve the audible results that i want?
- is it ergonomic or is there room to optimise by rearranging some modules?
- is it performable the way that i want?
- is it easy to get every module perfectly in sync without struggling with missing clock ticks?
- do i have enough headroom with my power supplies?
- is my lightning ok regardless where my rack is located?
- is there any audible result i want to achieve but not possible with modules i have?
- is it easy for me to find/grab the right patch cables?
- etc.

those are a few of my thoughts to optimize my personal rack...

using the "search similar racks" function i found a nearly identical rack:
maybe it includes the blurry modules that cant be recognized in the video...

Yesterday i wondered if its time to rearrange the (~160) modules in my rack from scratch
As its not possible to place modules to a specific position within the rack this is horrible monkeywork on huge racks
so much scrolling, so much zooming in and out, so much searching in the my modules list, so much fiddling around with the buggy hard to use module placement that requires pixel perfect movements...

so i had another idea to start with this task:
it would be great to work with module dummies in the real world before starting to persist the arrangement in modulargrid.
smaller versions (maybe 1:2) of each module printed on paper or cardboard which can be arranged & moved around on a desk.

using AI it shouldnt be that hard to convert existing images of the modules to printable blueprints/pictograms that can be printed to paper and cutted with a scissor.

So my huge feature request (or at least placing the idea for this feature) is an "export all my modules or a specific rack to printable A4 sheets"

I have to admit thats especially for users with huge racks because small racks are handleable completely digital within modular grid...
Maybe the idea is totally crap because some aspects are much more tedious than on modulagrid (like searching modules or to get a feeling for the arrangement with only a black/white mess of tiny pieces of paper/cardboard)
Any thoughts?

i have to remove those two M5 screws on each side. then i can lift the upper case:

maybe its more clear on my (unfinished) top case

of course this is not exactly applyable with your cases - but i think a similar solution would be possible. do you have pictures?

recently i built a custom case that consist of multiple stackable sub cases:
https://modwiggler.com/forum/viewtopic.php?p=3993355#p3993355

first i tried to use 8mm x 80mm metal bolts between the cases but i was not successful.
I was hoping to be able to stack & unstack the cases without the need for any tool.

after i realised that its totally ok for me using a tool in favour of a good connection between the cases i finally mounted a 3mm metal plate with 2 M5 holes on top of each sub case
it looks like a strong connection with nothing to worry about.

perfect - thanks a lot for your advice and explanation!

Hi,
Currently i am building a "modular" modular case. It consists of several cases that can be stacked to an unlimited height.
the very top (case-) module will have a 1 meter LED bar that emits to the ceiling.
This Led bar has a height of ~ 70mm so i will have space for a 1U row at the front.
I have no idea if i ever will use this 1U row for modules. for now i will create a huge blank panel for this
but i wonder in which distance i should drill the holes for the rails.

Researching the different 1U front panel heights brought me:
Intellijel: 39,65 mm
Pulp Logic: 1,7 inch which should be 43,18 mm

Is one of the formats more future proof than the other?
thanks for any advice or opinion!

further you can try to narrow down the cause by unplugging all modules in both cases and replug+check them one by one.

-- Loersatz

Hi,
I dont know the specific modules you are using. But maybe my (pretty short) experience with modular is helpful:

The trigger inputs on my modules mainly reacts when there is a voltage rise within a very short time in the input signal (RISE).
I can imagine that there are also trigger inputs that reacts to fast voltage drops as well (FALL).

All my sequencers that produces gate & pitch/CV have one thing in common:
The voltage of the pitch/CV output stays at the last sent value until the next gate with a different value is fired.
So the pitch/CV does not go back to zero volts after the step!
But the voltage of the gate-out goes always back to zero (time depends on gate length).

With that in mind you can try the following to produce gates that has different voltages and also jump back to zero volts after trigger.

route the pitch/CV signal of your sequencer through a VCA
use the the gate signal of your sequencer to control the VCA
plug the output of the VCA into the "dynamic trigger input" of your module.
pretty sure it will work!?
