Behringer System 100m

The modules are nearly half the size of the Roland originals. You still need the rack space.

Overview

The Behringer System 100m is not a single synth. It is a full set of Eurorack modules that replicate the Roland System-100M, a semi-modular analog system from the late 1970s. Behringer announced the series in 2020 at the NAMM show, as its latest move into vintage modular clones. The modules are direct, pin-for-pin interpretations of Roland's original designs, adapted for Eurorack power and mounting standards.

The original Roland System-100M lived in 19-inch rack frames with large, spaced-out modules. Behringer's version condenses that layout a lot. The modules are reportedly "nearly half the size" of the Roland originals, and they keep the same core signal path. Owners report the controls are solid for the price. Sliders and pots feel smooth and substantial, without the scratchy or loose behavior common in budget gear. A complete System 100m setup is 13 individual modules: three oscillators, three filters, three VCAs, two envelopes, mixers, modulation sources, and gate utilities. That is everything needed for standalone modular synthesis.

Even after the shrink, users keep saying the same thing: these modules are still big. On Modular Grid, one user wrote, “The immediate issue with using the Behringer System 100M modules is that they're HUUUUGE.” In Eurorack terms, that means deep panels and wide modules, and they eat rack space quickly. Still, for anyone chasing the Roland 100M's gritty, warm oscillators and 2-pole filters, the clone series builds 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 emulates the circuitry of the Roland System-100M, a semi-modular analog system from the late 1970s. That includes reproductions of core modules like the 110 VCO, 121 filter, 140 envelope generator, and 150 mixer, among others. Module numbers 110, 112, 121, 130, 131, 140, 150, and 173 have surfaced in user discussions and documentation, which points to a replication of the whole original lineup. Because Behringer stayed with the original designs, users can get the Roland sound, from its slightly unstable oscillators to its smooth but assertive filter response.

Sliders and Pots with Tactile Feedback

User reports, particularly ModWiggler forum posts, single out the physical interface of the System 100m modules for its quality. Sliders and potentiometers feel solid and responsive, a notable improvement over cheaper Behringer offerings. That matters in a modular setup, where constant tweaking is part of the workflow. The controls don't match the heft of vintage Roland components, but they avoid the flimsy feel that often plagues budget clones. They are suitable for live performance and studio patching.

High-Quality Envelope Generators

The envelope section gets particular praise. Multiple users say “the envelopes are of excellent quality,” which suggests Behringer got the response and stability of the 140-style envelope generators right. Envelopes shape the dynamics of sounds, and these have reliable, smooth decay curves. In a modular setup where envelopes drive filters and amplifiers, you need trustworthy ADSR circuits, and early user sentiment says these deliver.

Historical Context

Behringer announced the System 100m series in 2020, as part of a broader strategy to clone classic analog synthesizers in Eurorack format. The announcement came during the NAMM show. The series followed other Behringer clone projects, including the System 55, a Eurorack adaptation of the Moog System 55. The System 100m served users who wanted the sound of the Roland System-100M, a system known for its portability, integrated design, and use by artists in the early days of electronic music. With all the necessary modules released, users can assemble a complete, functionally identical version of the original system in a modern Eurorack case.

Collectibility & Value

The Behringer System 100m is a modern reissue, not a vintage collectible in the traditional sense. Its value is price relative to the original Roland hardware. The original Roland System-100M has climbed in price, driven by its cult status and scarcity, which makes the Behringer clone an attractive alternative. A used complete set of 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. Given the modular design and standard Eurorack power requirements, reliability is expected to match typical Behringer product longevity.
