Doepfer A-118 Noise and Random Voltage Generator
A-118 Noise/Random · Doepfer
11 for sale on Reverb2 finishes at Thomann
This is a noise and random voltage module. It gives you white noise and coloured noise, which you can use as audio, and random voltage, which is mostly used to control other parts of your setup. It suits you if you want a small 8HP module with knobs to set how fast and how strong the random voltage changes, and LEDs that show what it is doing.
Pros
- Generates white noise, coloured noise, and random voltage from one module
- Noise works as an audio signal or as a control voltage
- Knobs set the rate of change and amplitude of the random voltage
Cons
- Random voltage is mainly used as a control voltage, given its low frequency content

Behringer 903A Random Signal Generator Eurorack Synthesizer Module
903A Random Signal Generator · Behringer
4 for sale on Reverb1 finish at Thomann
This is a small analogue noise module with two outputs, one for white noise and one for pink noise. At 4 HP wide, it takes up little space in a Eurorack case. It suits you if you want a simple, budget-friendly noise source for your modular setup.
Pros
- Analogue noise generator, so the noise is made by analogue circuitry
- Two separate outputs, one for white noise and one for pink noise
- Compact 4 HP width fits easily into a small Eurorack case
Cons
- Generates only white and pink noise, with no other noise types listed
-
You get a noise and random voltage module that takes up just 4 HP. It gives you white noise, coloured noise that you can mix in, and a random voltage output with its own level control. You can switch it between Track & Hold and Sample & Hold, so it suits anyone building Eurorack patches who wants random sources to play with.
Pros
- Outputs white noise, giving you a hiss source to start patches
- Coloured noise output can be mixed with white noise in your chosen proportions
- Continuous random voltage output comes with its own level control
Cons
- Needs +12 V and -12 V power, drawing 20 mA on each rail
-
The A-117-2 is a workhorse noise module – simple, reliable, and sounds great. It’s a fantastic starting point for anyone exploring noise generation in Eurorack, or a useful utility for experienced users needing a compact, flexible noise source. Its clean digital character is surprisingly versatile.
Pros
- Excellent noise quality, surprisingly rich and textured for a digital module.
- Wide frequency range (50-40kHz) allows for subtle to harsh noise.
- Compact 4HP footprint makes it ideal for dense modular setups.
Cons
- Limited output options; bipolar/unipolar can restrict certain patching scenarios.
- Relatively basic functionality compared to more complex noise generators.
-
You get two noise sources that switch between white and pink, plus two random voltage generators, all in one 14 HP Eurorack module. This suits you if you build a modular rig and want sources for random voltages or noise signals. Check that your case can supply +12 V at 45 mA and -12 V at 15 mA before you buy.
Pros
- Two independent noise generators, each with a selector for white or pink noise
- Each noise generator has its own level control with a maximum of plus or minus 5 V
- Two random voltage generators, each with its own attenuator and on/off switch
-
If you build a Eurorack modular system, you will like this module because it packs several useful tools into one panel. You get pink and white noise, a clock and random pulse source, a sample and track and hold block, and a slew block. It suits anyone who wants random and sample-and-hold ideas in their patch without using up a lot of rack space.
Pros
- Analogue pink and white noise sources give you two noise colours to work with
- Clock and random pulse source has an adjustable rate for changing patterns
- Sample/Track and Hold block lets you capture and freeze voltages
Cons
- Only 22 HP wide, so it takes up a good share of a small rack

The VCNO is a seriously characterful noise module; it's not a general-purpose solution, but if you're into granular textures and experimental sound design, especially glitchy percussion and evolving drones, it's a fantastic addition to your rack. It's perfect for sound designers and noise-focused modular enthusiasts seeking a unique sonic palette.
Pros
- Unique 'Sizzle' output adds complex harmonic textures.
- DC-coupled gate output enables intricate rhythmic possibilities.
- Compact 6U width maximizes modular space efficiency.
Cons
- Limited noise type variety compared to dedicated noise generators.
- Power draw, while not excessive, can strain smaller power supplies.

Noise Modules by the numbers

How to choose the best noise modules
Noise Types
Does it offer a variety of noise types - white, pink, brown, filtered, granular? A wider palette means more sonic possibilities, crucial for evolving textures.
Modulation Options
Can you modulate the noise's pitch, density, or filtering? Static noise gets boring fast; modulation breathes life into it.
Signal-to-Noise Ratio
This is critical. A noisy noise module is just...noise. A good one will have a decent S/N ratio so you can hear the subtleties.
Filtering Capabilities
A resonant low-pass filter can turn white noise into a screaming drone. A high-pass can add crispness. Versatility is key.
Build Quality
At this price point, expect some compromises. We're looking for something that won't fall apart if you bump it in your rack, even if the case isn't the fanciest.
Buying guide
Alright, so you're diving into the modular world and need some noise? Smart move - a little controlled chaos goes a long way. Finding good noise modules under $200 can be tricky, though; you're not gonna get the boutique, ultra-refined textures of the top-tier stuff. But there are some seriously usable options out there that'll add grit, texture, and unpredictable movement to your patches without breaking the bank. Let's get into it.
Real talk: under $200, you're making trade-offs. Don't expect ultra-low noise floors or exotic noise generation techniques. Often, you'll find simpler designs with fewer modulation options, but that's not always a bad thing.
Focus on modules that offer a good range of noise types and, crucially, decent filtering - that's where you'll get the most mileage. A cheap module with a good filter is worth more than a 'complex' module that just makes generic hiss.

Questions
What's the difference between white, pink, and brown noise?
White noise is that classic hiss, like static. Pink noise has more low-end, sounding 'fuller' or 'warmer'. Brown noise is even more bass-heavy, almost a rumbling texture. They all have different feels and applications.
Can I use these modules for percussion sounds?
Absolutely! With some clever gating and filtering, you can create surprisingly realistic drum sounds or glitchy percussion textures. Think of brown noise as a good starting point for a gritty kick drum.
What does 'modulation' mean in this context?
It means using other signals - LFOs, envelopes, sequencers - to change the noise's characteristics in real-time. It's what transforms static noise into something dynamic and interesting.
Are these modules suitable for recording?
They can be, but be mindful of the noise floor. A noisy module can muddy a clean recording. Experiment with filtering and gating to tame the noise and make it work for your track.
Is there a 'best' module at this price?
Nah, it's all about what you need. Some excel at raw noise generation, others at filtering and modulation. Research a few, watch some demos, and choose the one that best fits your patching style.
