Behringer System 100m
At nearly half the size of the Roland originals, these Eurorack modules pack a vintage analog soul into a modern format — if you've got the rack space.
Overview
The Behringer System 100m isn't a single synth, but a full suite of Eurorack-format modules designed to replicate the functionality and character of the Roland System-100M, a semi-modular analog powerhouse from the late 1970s. Announced in 2020 at the NAMM show, the System 100m series marked Behringer’s latest move into the vintage modular clone market, following a strategy of reissuing classic architectures in accessible formats. These modules are not mere inspirations — they’re direct, pin-for-pin interpretations of Roland’s original designs, adapted for Eurorack power and mounting standards.
While the original Roland System-100M lived in 19-inch rack frames with large, spaced-out modules, Behringer’s take condenses that layout significantly. The modules are reportedly "nearly half the size" of the Roland originals, yet still manage to retain the same core signal path architecture. Owners report the build quality of the controls is solid for the price: sliders and pots feel smooth and substantial, avoiding the scratchy or loose behavior common in budget gear. A complete System 100m setup comprises 13 individual modules, forming a self-contained analog system with three oscillators, three filters, three VCAs, two envelopes, mixers, modulation sources, and gate utilities — essentially everything needed for standalone modular synthesis.
Despite the compacting, one recurring user observation stands out: these modules are still big. On Modular Grid, one user emphasized, “The immediate issue with using the Behringer System 100M modules is that they're HUUUUGE.” In Eurorack terms, “huge” means deep panel real estate and wide module widths, which can quickly eat up rack space. Still, for those chasing the Roland 100M’s gritty, warm oscillators and characterful 2-pole filters, this clone series offers a rare chance to build that system without selling a kidney — the original Roland units now command steep prices on the vintage market.

Key Features
Clone of Roland System-100M Architecture
The Behringer System 100m series directly emulates the circuitry of the Roland System-100M, a revered semi-modular analog system from the late 1970s. This includes faithful reproductions of core modules like the 110 VCO, 121 filter, 140 envelope generator, and 150 mixer, among others. Module model numbers such as 110, 112, 121, 130, 131, 140, 150, and 173 have surfaced in user discussions and documentation, indicating a comprehensive replication of the original lineup. By staying true to the original designs, Behringer enables users to recreate the distinctive sonic character of the Roland system — from its rich, slightly unstable oscillators to its smooth yet assertive filter response.
Sliders and Pots with Tactile Feedback
According to user reports, particularly from ModWiggler forum posts, the physical interface of the System 100m modules stands out for its quality. Sliders and potentiometers feel robust and responsive, a notable improvement over cheaper Behringer offerings. This tactile precision matters in a modular environment where constant tweaking is part of the workflow. While not matching the heft of vintage Roland components, the controls avoid the flimsy feel that often plagues budget clones, making them suitable for live performance and studio patching.
High-Quality Envelope Generators
One standout component is the envelope section. Multiple users have highlighted that “the envelopes are of excellent quality,” suggesting that Behringer nailed the response and stability of the 140-style envelope generators. These are critical for shaping the dynamics of sounds, and their reliability and smooth decay curves contribute significantly to the overall musicality of the system. In a modular setup where envelopes drive filters and amplifiers, having trustworthy ADSR circuits is essential — and early user sentiment indicates these deliver.
Historical Context
Behringer announced the System 100m series in 2020, positioning it as part of a broader strategy to clone classic analog synthesizers in Eurorack format. The announcement came during the NAMM show, a traditional launchpad for major music tech releases. This series followed other Behringer clone projects, including the System 55, itself a Eurorack adaptation of the legendary Moog System 55. The System 100m filled a niche for users seeking the specific sonic palette of the Roland System-100M — a system known for its portability, integrated design, and use by artists in the early days of electronic music. By releasing all the necessary modules, Behringer enabled users to assemble a complete, functionally identical version of the original system within a modern Eurorack case.
Collectibility & Value
While the Behringer System 100m is a modern reissue and not a vintage collectible in the traditional sense, its value proposition lies in its affordability relative to the original Roland hardware. The rising prices of the original Roland System-100M, driven by its cult status and scarcity, make the Behringer clone an attractive alternative. A used complete set of Behringer System 100m modules with a case was listed for $1,180.95 in “Mint” condition, a fraction of what even a single original Roland 100M module can fetch today. There is no documented data on common failures or long-term maintenance issues, but given the modular nature and standard Eurorack power requirements, reliability is expected to align with typical Behringer product longevity.
