I made this little performance a few weeks ago.. quite happy how it turns out!
please tell me what you think !

A small patch with Marbles, Rings and some piano playing. Comments welcome…:-)

I’ve been a eurorack user for 10 years and I finally ran out of my trusty M3x8mm socket head hex screws (with nylon washers of course). This comes right as I’m building a new rack for DIY modules.

I ordered a pack on Amazon and was surprised to find their diameter is ever so slightly too big for these synthrotek rails with sliding nuts. I’ve never had this problem and I’m not sure if it’s the rails or screws, since my other systems use Z rails and whatever tip top uses. The screws from my other racks fit these just fine, so I would think it was the screws except for the fact that I’ve ordered 3 different sets of these on Amazon from different sellers and the only ones that fit come exclusively in an assortment of lengths (to use in separate projects), so I’ll be back to square one once I use up my 32 M3x8 0.05 pitch screws.

What’s going on? I’ve never had this problem and I can’t find much online.

Hello,

That Happy Nerding 3xVCA should be a 3xMIA

I’m very new to Eurorack and accept that I expanded too quickly! I’m sure this isn’t uncommon. I greatly enjoy thee little boxes.

Everything except the Bruxa and Iroi are currently on my rails. End goal is to produce a cross creepy / psychedelic material with intermittent vocals. 

I'm looking for suggestions of things to switch out, adding/removing. I’ve been toying with the idea of starting a 2nd rack for the Bruxa, Iroi, and complimenting modules. I am far from knowledgeable right now, so let me have it!

Thank you in advance.

Hey everyone 👋

I released a new EP last friday.

"Empyral Emittance" is a dive into a cosmic pantheon of dying gods. Dark, drone-y, epic, and at times disturbing, it was completely made with my eurorack synth - only mastering was done in a DAW.

Hope you enjoy!

Here's another update to the unofficial, community-driven firmware patch for the Bitbox Micro that puts more of the module on MIDI, and **2.3.10-mod** is ready for release.

It's the massive jungle toolkit your Bitbox has been waiting for! Three new Clip modes: an early-'90s time-stretch, vinyl pitch, and a transient-preserving Key Lock. Combine them with the new Live Flip modes, 24 re-sequencing patterns for your loops, and 7 hold buttons to mash things up with some turntablism.

Three new Clip modes, synced to your clock or on their own tempo:

• Vinyl: Speeds up and slows down like a turntable, so the pitch rises and falls with the tempo.
• Jungle - Stretch like an early-'90s sampler with Modern or Old Skool flavas with pitched sequence support.
• Key Lock - Stretches smoothly, keeping transients intact, with pitched sequence support.

Clip aware settings for each of the three clip modes:

• Manual - Sets a pad's tempo, for slow junglist stretches.
• Cycles - plus a Modern or Old Skool flava.

And there's more:

• Live Flip modes: 24 ways to re-sequence your loop live from an encoder, always in time: repeats, reshuffles, chops, reverse swells and harmonies. Intelligent, material aware re-chopping of your clips on the fly.
• Trigger buttons: Pull Up, Power Down, Brake, Baby Scratch, Roll, Pitch Roll and Freeze. Let go and the loop drops in time.
• Three Airwindows compressors beside the stock one: Logical4, VariMu and Thunder. Auto makeup gain is improved, with a new Hot setting.
• Themes: pick one of five, or roll your own in the theme maker.
• The Character chain and compressor settings survive a power-off.
• Preset BPM runs from 1 to 255, up from 40 to 250.
• Lighter on the CPU, same sound.

You asked for Airwindows compressors, time-stretch you can pitch, and screen colours you can change when they're hard to read. Here they are, rude boys and girls. Big up everyone who sent ideas, and keep them coming, here or in Discussions on the GitHub page.

This isn't from 1010music, can't brick your module, but bring your own stock firmware, don't pass the patched firmware around.

Full guide, including what each control does and how to set your presets:

Hi

So I don’t have a mixer with send return, just a regular 4channnel with eq and main out. Any suggestions how I can create a send return to my fx without breaking the bank on a mixer with send ?

Cheers

Hello, good people. I've been trying to identify these modules one of my favorite musicians used on stage since January. The only one I've been able to figure out is Gieskes Klok on the right. I was hoping the middle left one would be easy based on the distinct blue color, the control layout, and its size, but still no luck. I guess the middle right one could only by identified by the control layout. And I'm pretty sure the narrow one on the left is just a utility module like volume or something like that.

I know the quality of the pictures is really bad. The case with the gear was positioned away from the crowd, so these are the only kind of decent pitctures there are. The musician is also not known for Eurorack gear and there's no info on it.

This has been bothering me for so long, so thanks in advance for any efforts

Hi

Just wanted to bring something up I don’t see a lot about but I think it could be a problem / challenge for many. I got a mild tinitus probably from going clubbing and concerts in my younger years when I was more careless. I now use earplugs when going out.
Besides from (obviously) keeping volume low any advises to have our hobby and same time protecting our ears in these long sessions and if you play live events where to volume is sometimes dangerously high. Can you actually sustain making music with ears that have been damaged. Any recommendations on earplugs or other good equipment very welcome . My concert earplugs are not really good for this purpose.
Cheers

I feel like Maths, Disting, Mutable modules and some others are the standard "intro to modular" modules, but I've been wondering if I've just outgrown it and want something more complex that does everything Maths does and more, or a more complex approach overall. (Or maybe Maths has vastly more hidden secrets and uses I haven't found nor use)

For example, Thorn Audio just came out with Splines, which lets you create quite a wild array of envelopes, and modulate them. It of course doesn't have mixing capabilities, but if you just want to make an evolving complex CV shape, Splines does that in spades. I don't mean it's a direct replacement, but this is an example of one Maths use that another module does far better, IMHO.

So on the one hand, there are basic utility modules (mults, vcas) that are essential even when you advance. On the other hand are there modules we just keep around out of habit or a general sense that we just sort of "should" have them, even though other approaches exist?

How do you all feel about your modular evolution in this respect?

Hey everyone! Cuisine has come a long way since the original launch, so I wanted to pull everything together into one comprehensive video manual.

Whether you're getting started for the first time or just catching up on recent updates, it's fully timestamped so you can jump straight to what you need:

Happy to answer any questions!

He estado trabajando en la creación de un sistema modular de bajo consumo que funcione en cualquier ordenador. Estos son los módulos funcionales; puedes enviar y recibir señales mediante potenciómetros. Tienes opciones para cambiar los colores de la interfaz, seleccionar los colores de los cables, cambiar el fondo, y este también modifica la interfaz según los colores de la imagen que subas.

El modo clásico de cuadrícula Eurorack también está disponible; el modo libre, que se muestra en la imagen, permite minimizar los módulos, ocultar los cables y cambiar la opacidad de los cables y el fondo.

Puedes grabar tus sonidos y exportarlos a WAV, guardar proyectos y temas, y abrirlos. Es un proyecto que diseñé específicamente para ordenadores de gama baja, ya que Cardinal consume muchos recursos y VCV no funciona en ellos. No existe una versión de Eurorack para Android como tal, por lo que las opciones para disfrutarlo son algo limitadas; por eso creé este proyecto para todos aquellos que aún no lo han hecho público.

No es que la IA lo haya hecho todo por mí, ya que antes me dedicaba a escribir código para los módulos Cherry Audio Modular Voltage y a corregir algunos errores en ciertas aplicaciones; todo lo que se muestra está en desarrollo. Y básicamente está construido desde cero.

Probablemente haré un tutorial en español para que los nuevos usuarios aprendan a usar este sistema.

Hi! I'm trying to decide between the Moog Subharmonicon and the MachineRoom Trilobite, and I'd really appreciate your advice.

My current setup includes a Moog DFAM and a Westlicht Performer. I'm also considering adding Mutable Instruments Plaits with the alternative Plaits Palette firmware, using its chord tables for microtonal harmonies inspired by Ivan Wyschnegradsky.

I'm aiming for dark, industrial, dissonant techno inspired by Stanislav Tolkachev. In particular, I want to create thick, tense analog chords by detuning and combining multiple oscillators, similar to using three Befaco Even VCOs.

Would you recommend the Trilobite for its three analog VCOs and independent pitch control, or the Subharmonicon for its subharmonic chords and polyrhythmic possibilities?

Considering that I already have the DFAM and the Westlicht Performer, which would complement my setup better and give me the sound I'm looking for?

Thanks for your help!

Modular, one take — 18 October 2026

Six voices played from one string controller, chords by hand, no computer.

Drums, bass, chord swells, stabs and granular textures come from a small sequencer I wrote for the Ornate Criminal (a Eurorack module on a Teensy, Phazerville firmware). Each voice has a bank of patterns and three levels of intensity. The string sets how busy the drums and bass are and sweeps the effects. Chords are played by hand and harmonised in the case.

Drizzlet is free, open-source firmware for Beads, built on the source Mutable Instruments released. Beta 1 is out, and I'm looking for people to try it on their own modules. Every new option defaults to stock behavior, so Beads works as before until you change something.

New, in order of how often they were requested: - Clouds-style reverb - Buffer trim (Mutable Instruments' own unreleased gesture) - Stereo width for grains - Delay mode: keep SIZE fully clockwise granular, or a wider neutral zone for the delay filter - Pitch scales from Marbles - Wavetable synth on demand, so it no longer starts by itself after 10 s - Monophonic grains (another unreleased MI gesture). As Mutable Instruments noted, it works well only with the first two SHAPE settings, square and decay. - Output limiter options (Stock, Fast release or Off) for the volume drops after loud, dense passages, which Mutable Instruments traced to the limiter's slow recovery

Fixes: - A modulated FREEZE no longer wears out the flash by starting a new save every cycle. - Safer frozen-buffer saves. - Two delay-mode bugs.

It's also a bit faster, with the same sound.

Tested on one module so far: about 13 hours of automated runs and 48 flashes, and it has never failed to boot. Install at your own risk, and please don't contact Mutable Instruments about it.

Release, install steps and options guide: https://github.com/insolentconstruct/eurorack/releases/tag/drizzlet-2026.10.18

Bug reports and feedback are welcome in the GitHub issues.

I'm looking to dust off my iron and refresh my long dormant electronics knowledge and I'm looking for good collections of DIY build guides.

I'm aware of Hagiwo, but I'm looking for more - bonus points if they have more detail than just a circuit diagram.

I'd also love any insight on Hagiwo's builds from people who've made them - are they any good?

Here's another update to the unofficial, community-driven firmware patch for the Bitbox Micro that puts more of the module on MIDI, and 2.3.9-mod is ready for release, now including sixteen Airwindows effects on the master bus, and an on-screen display for controller parameters.

In this release:

• The Character chain: Four effect slots across the master bus, each with an Amount, a Tone. Thanks to Chris Johnson for making this possible with his awesome Airwindows plugins, for full details checkout the Airwindows site.

  • Destruction, lo-fi and breakage: Pockey2, DeRez3, Ring Mod, Fracture2.
  • Overdrive, warm tube to dirty harmonics: Tube2, Drive, Mackity, Huge.
  • Colour, consoles, tape and a transformer: Channel9, IronOxide5, ToTape8, Coils2.
  • Saturation, smooth weight and density: PurestDrive, Spiral2, Density3, Mojo.

• OSD pop-ups: every patch CC shows what it changed, in real units. The clock gets them too.

• A CPU bar along the bottom of the screen.

• Preset BPM: Adjust a preset's tempo directly on the module and save the preset. With Clk Loss on HOLD, it also captures a clock's tempo.

• Auto makeup gain for the compressor

• Keep CC's option that restores your controller parameters when you load a new preset.

Fixed: MIDI notes could change compressor, EQ or delay settings.

Fixed in the guide: the EQ comes before the compressor, not after it.

This isn't from 1010music, can't brick it, but bring your own stock firmware, don't pass the patched firmware around.

Drizzlet is a community firmware for Beads, built on the source Mutable Instruments released this month. Alpha 2 is out.

New in alpha 2: - Self-play on request: a new option stops Beads starting self-play by itself; with no inputs patched and FREEZE off, hold MEDIA for 1.5 s to start or stop it. - Monophonic grains: Mutable Instruments' previously unreleased mode, toggled with MEDIA+SEED; as Mutable Instruments noted, it works well only with the first two SHAPE envelopes (square and decay). - Bug fixes in the released source: less flash wear when an LFO or long gates drive FREEZE, a delay clock glitch, and a frozen-delay slice bug.

From alpha 1: - Output limiter option: Stock, Fast release or Off, set on a new options page (hold ASSIGN for 3 s). - Safer frozen-buffer saves: checked when loaded, and a save that was cut short is never restored. - Bug fixes in the released source: out-of-bounds and uninitialized reads (frozen delay, synth mode, CPU padding), and buffer saves that could fail or be marked complete when they weren't.

Crackle: at the settings people reported, our test module clicked on the 2021 and 2024 firmware but not on Drizzlet; the fix is in Mutable Instruments' released source.

Download and install notes: https://github.com/insolentconstruct/eurorack/releases/tag/drizzlet-2026.10.16

It's an alpha: read the README first and install at your own risk. Not a Mutable Instruments product.

Testing: 125 tests in 11 host test programs (693 assertions) covering 110 of 117 manual behaviours (3 only in part), 112 deliberate-fault mutations, 531 injected power-loss and flash-error points, byte-reproducible builds, emulator comparisons, and checks on a real module. Details: https://github.com/insolentconstruct/eurorack/blob/drizzlet/beads/build/TESTING.md

Next (Beta 1, tentative): buffer trim (Mutable Instruments' own disabled feature, made to survive a save), pitch quantization, Clouds-style diffusion and reverb if CPU allows, and, if headroom remains, Arbhar-style grain starts on recorded attacks.

I used a brand new Eurorack version BlueBox Mixer in my Behringer Eurorack Go where the Mixer was Blinking. I then upgraded to a Doepfer A-100 PSU3 because I thought power was the problem. 20 Minutes in, started blinking. Both were trialed at 100% Brightness.

When I turned the brightness down, it stopped blinking. Thing is, I want to use it at 100% without it blinking.

I'm going to return it for a new one, but wanted to ask if anyone else's blinked? I'm worried about waiting for a whole new one only to have it blink again :T..
