Behringer 112 Dual VCO Analog Eurorack Module Review: Authentic Vintage Power or Tuning Trouble?
For many of us who have fallen down the modular rabbit hole, there is a specific, almost mythical tone we chase: the Roland System 100M. Back in the 1980s, these units were the gold standard for compact, modular synthesis, offering a punchy, warm, and distinctly Japanese analog flavor that defined a generation of electronic music. However, finding an original unit today usually involves scouring auction sites and being prepared to part with several thousand dollars for a module that might need immediate servicing. I’ve spent years trying to replicate that specific oscillator drift and harmonic richness using software, but there’s always something missing in the tactile feedback and the raw voltage interaction.
This is where the Behringer 112 Dual VCO Analog Eurorack Module enters the frame. It promises to bring that exact circuitry—the dual-oscillator heart of the System 100M—into a modern Eurorack format at a price that seems almost too good to be true. When we first integrated this module into our test rig, we were looking for more than just a “cheap” alternative; we were looking for a primary sound source that could hold its own against boutique competitors. Solving the problem of high-entry costs for authentic analog synthesis is crucial, as many producers are currently forced to choose between thin-sounding digital clones or breaking the bank on vintage hardware. Failing to find a middle ground often leads to “gear paralysis,” where the lack of an inspiring sound source halts the creative process entirely.

What to Consider Before Buying Tabletop Synthesizers and Eurorack Modules
A Tabletop Synthesizers or Eurorack module is more than just an item; it’s a key solution for sonic identity and workflow efficiency. In the modern studio, the choice of a sound generator dictates the entire texture of your production. Whether you are building a custom rack or looking for a standalone desktop unit, you are essentially investing in the “engine” of your music. These devices solve the problem of generic, “in-the-box” sounds by providing unique harmonic distortion, organic pitch fluctuations, and a hands-on interface that encourages happy accidents.
The ideal customer for this type of product is someone facing a stale creative routine or someone who wants to understand the fundamentals of subtractive synthesis through a physical medium. It’s perfect for the “tinkerer” who enjoys patching and signal flow. On the other hand, it might not be suitable for those who require instant total recall (saving presets) or those who need a portable, battery-powered solution without the hassle of power supplies and mounting rails. For those users, a digital groovebox or a software-based system might be a more practical alternative.
Before investing, consider these crucial points in detail:
- Dimensions & Space: In the Eurorack world, space is measured in Horizontal Pitch (HP). The Behringer 112 Dual VCO Analog Eurorack Module takes up 16HP, which is quite substantial for a dual oscillator. You need to ensure your case has the room and, more importantly, the depth to accommodate the module’s PCB and power ribbon.
- Capacity & Performance: Look specifically at the tracking stability (Volts per Octave) and the power draw. This module requires 130 mA from the +12 V rail and 70 mA from the -12 V rail. We found that checking your power supply’s overhead is vital before adding multiple analog oscillators.
- Materials & Durability: Not all modules are built equally. A metal faceplate and sturdy, chassis-mounted potentiometers are essential for longevity, especially if you plan on performing live. The “feel” of the knobs—whether they are “wiggly” or firm—significantly impacts your fine-tuning capability.
- Ease of Use & Maintenance: Analog gear requires a warm-up period to reach pitch stability. You should consider whether you are comfortable with “fine-tuning” and occasional calibration. Some modules have trim pots on the back that may need adjustment over the years to keep the tracking accurate across multiple octaves.

First Impressions and the Anatomy of the Behringer 112 Dual VCO
When we first pulled the Behringer 112 Dual VCO Analog Eurorack Module out of its box, the immediate impression was one of surprising solidity. Despite the affordable price point, the module features an alloy steel body and a clean, multicolor faceplate that screams 1980s industrial design. It feels heavy in the hand—roughly 500 grams—which gives it a sense of “real instrument” status rather than a cheap peripheral. We were pleased to see its full feature set and user reviews reflected accurately in the physical build, with all 18 controls feeling responsive and logically laid out.
Compared to previous Behringer clones or even some high-end boutique oscillators, the 112 doesn’t try to reinvent the wheel. It is a faithful reproduction of the System 100M circuitry. Each of the two VCOs is independent, featuring a range knob (octave select), a pitch knob for fine-tuning, and a dedicated waveform selector. You get Triangle, Sawtooth, and Square waves—the bread and butter of classic synthesis. One thing that stood out during our initial test was the inclusion of both “Strong” and “Weak” sync modes, a feature often omitted in budget modules but crucial for creating those aggressive, tearing lead sounds that sync-modulation is known for.
What We Like
- Incredible value, providing two independent, high-quality analog oscillators in one 16HP unit.
- Authentic “Roland” sound profile: warm, harmonically rich, and slightly “woolly” in the best way possible.
- Extensive CV connectivity with 3 CV inputs per VCO, allowing for complex modulation of pitch and pulse width.
- The octave range switch is a massive workflow booster for quick sound design and performance.
What We Didn’t Like
- The labeling at the top of the module can be quite small, making it difficult to read in dimly lit studios or behind a forest of patch cables.
- Analog stability issues: like many vintage designs, it requires a significant warm-up time (15-20 minutes) to hold a stable tune.
Deep Dive: Performance and Sonic Character of the Behringer 112
Oscillator Stability and the Analog “Warm-Up” Ritual
In our extensive testing of the Behringer 112 Dual VCO Analog Eurorack Module, we discovered that this module is a “true” analog beast. What does that mean in practice? It means that if you flip the power switch and expect it to be perfectly in tune with your digital piano immediately, you will be disappointed. We found that the module needs about 15 to 20 minutes to reach internal thermal equilibrium. Before this, the pitch can drift significantly. However, once it reaches that “sweet spot,” it becomes remarkably stable. For those who have been working with modular for decades, this is standard behavior, but for newcomers, it’s a vital detail to understand.
We tracked the 1V/Octave input across five octaves. In the middle three octaves (C1 to C4), the tracking was nearly flawless. At the extreme ends, we noticed some minor deviation, but nothing that couldn’t be fixed with a quick nudge of the fine-tuning knob. One user in our community noted they had trouble tuning the unit at all, but in our experience, this often comes down to the quality of the power supply or the calibration of the CV source. When fed a clean signal from a high-quality sequencer, the 112 sang beautifully. If you are looking for that organic, slightly “breathing” pitch character, you can check the latest price and availability to see if it fits your current rack budget.
Waveform Sculpting and Pulse Width Modulation
The core of any VCO is its waveforms, and the 112 delivers the “System 100M sound” with precision. The Sawtooth is buzzy and rich, perfect for those classic 80s basslines. The Triangle wave is surprisingly clean, providing a solid foundation for sub-bass duties or FM (Frequency Modulation) carrier signals. However, the standout for us was the Square wave with its Pulse Width Modulation (PWM) capabilities. Each VCO has a dedicated PWM slider and a CV input for external modulation.
We spent hours modulating the PWM with a slow LFO while simultaneously sweeping the pitch. The result was a thick, chorus-like texture that sounded incredibly wide, even before adding any external effects. Because there are two oscillators on one board, you can slightly detune them against each other and modulate their pulse widths at different rates. This creates a “wall of sound” that digital oscillators often struggle to emulate. The ability to control PWM manually and via CV simultaneously is a feature that really sets it apart in this price bracket, giving you more real-time control than many “single” VCO modules that cost twice as much.
The Power of “Strong” and “Weak” Sync
Oscillator sync is a technique where one VCO (the master) resets the phase of another (the slave), creating complex, harmonically dense waveforms. The Behringer 112 Dual VCO Analog Eurorack Module provides two flavors of this: Strong and Weak. Strong sync is the classic “hard sync” sound—aggressive, nasal, and perfect for industrial leads. Weak sync is more subtle, allowing for interesting phase-locking effects that don’t completely mangle the slave oscillator’s fundamental frequency.
In our studio sessions, we used VCO 1 as a master to sync VCO 2. By sweeping the pitch of VCO 2 while sync was engaged, we achieved those iconic “tearing” sounds found on many classic synth-pop records. The fact that Behringer included two sync modes allows for a much broader palette of aggressive tones. We found the Weak sync particularly useful for “thickening” a sound without losing the melodic clarity of the notes being played. It’s a level of nuance that we didn’t expect to find on a module in this category.
Ergonomics and Integration: The 16HP Reality
Integrating the Behringer 112 Dual VCO Analog Eurorack Module into a workflow requires some planning. At 16HP, it’s a “wide” module. While this takes up more real estate in your case, it also means the controls are not cramped. We appreciated the large sliders and the distinct “click” of the range switches. However, we must echo a sentiment found in many user reviews: the labels at the top of the module are tiny. If you have your rack at eye level, it’s fine, but if it’s sitting on a desk below you, you might find yourself squinting to see which jack is which.
That being said, the connectivity is excellent. With two audio outputs per VCO, you can send one wave to a filter and another to a wavefolder, or use them to create a stereo image. Having three CV inputs per VCO means you can modulate pitch, PWM, and FM all at once without needing a separate mult module. For anyone building their first rack, we believe this is a fantastic module that will get you going and provide years of utility before you ever feel the need to “upgrade.”
What Other Users Are Saying
The general consensus among the modular community regarding the Behringer 112 Dual VCO Analog Eurorack Module is overwhelmingly positive, centered mainly on its “bang-for-buck” ratio. One enthusiast described it as “stable as a rock” after the necessary warm-up period, highlighting that the octave switch is a game-changer for live performance. Another user praised the build quality, noting that Behringer is delivering “quality products at a cheaper price,” making the hobby more accessible to everyone. We agree that for the vast majority of users, the sonic performance far outweighs the minor ergonomic complaints.
However, the feedback isn’t without its warnings. A few seasoned modular users—some with over 50 years of experience—reported difficulties in getting the oscillators to tune or track together. While this could indicate quality control variances, it also highlights the “fussy” nature of 100% analog circuitry. As one user aptly put it, “After the fine adjustment, it is perfect.” This suggests that a bit of patience and perhaps some internal calibration might be required for the most demanding technical applications. If you’re willing to put in that small amount of effort, the reward is a truly legendary sound profile at your fingertips.
Comparing the Behringer 112 to Top Alternatives
While we are impressed with the 112, the “tabletop synthesizer” world is vast. Depending on your needs—whether you want a full groovebox, a standalone bass synth, or just something fun—there are other options to consider.
1. Novation Circuit Tracks Electronic Music Groovebox Sequencer
- Unleash your creativity and make limitless music with two synth tracks, two MIDI tracks and four drum tracks. Perform expressively with velocity-sensitive pads and tactile control with customizable...
- Create 32-step patterns, chainable for up to 256 steps sequences per track. Go off-grid with microtiming. Keep your music evolving with probability and pattern mutate
The Novation Circuit Tracks is a completely different beast. While the Behringer 112 is a single component in a larger system, the Circuit Tracks is a self-contained production station. It features two digital synth engines, four drum tracks, and two MIDI tracks to control external gear. If you are looking for a “brain” for your studio rather than an analog building block, the Circuit Tracks is the better choice. It offers portability and presets that the 112 simply cannot match. However, it lacks the raw, unadulterated analog “soul” and the modular patching flexibility of the 112.
2. KORG Volca Bass Analog Synthesizer
- Powerful analog bass sound creation with three oscillators for a variety of bass sounds
- Electribe-inspired sequencer for generating ultimate bass lines and grooves
If you love the analog sound but aren’t ready to commit to the Eurorack format, the Korg Volca Bass is a formidable alternative. Like the 112, it is a true analog synthesizer, but it comes with its own built-in sequencer and three oscillators that can be played in unison or independently. It’s much more portable and fits easily on any desk. However, the Volca Bass is limited in its modulation routing compared to the 112’s multiple CV inputs. For those who want to “patch” and grow a larger system, the Behringer 112 is a better long-term investment, whereas the Volca is perfect for immediate, standalone fun.
3. Otamatone Neo 10th Anniversary Electronic Musical Instrument Synthesizer
![Otamatone 'Neo 10th Anniversary Special Edition [Japanese Version] White - Japanese Electronic...](https://m.media-amazon.com/images/I/21YTfcxjhuL.jpg)
- : W 2.6 x H 11.2 x D 5.4 inches (6.7 x 28.5 x 13.7 cm)
- : 3 ()
The Otamatone Neo is included here as a wildcard. It is a “synthesizer” in the broadest sense, but it is more of a performance toy than a studio tool. It uses a unique “slide” interface to create vocal-like synth tones. While it’s incredibly fun and a great gift for musicians, it doesn’t offer the precision, harmonic depth, or connectivity of the Behringer 112. If you are serious about sound design and building a professional-grade modular rack, the 112 is the obvious choice. If you want something to make people laugh at a party, go with the Otamatone.
