Behringer 1050 Mix-Sequencer
A 24HP Eurorack module that works as an 8-channel mixer and a step sequencer, drawing on a 1970s modular system
Overview
The Behringer 1050 Mix-Sequencer is not a standalone brain for your rack. It patches, blends and sequences inside a modular system. Behringer markets it as part of its "Legendary 2500 Series," and it recreates a component from the original ARP System 2500, a modular synth line built between 1970 and 1981. There is no screen and no MIDI-over-USB. It is an analog-style module that gets wired into a Eurorack case and responds to control voltages and gate signals. It is 24HP wide and draws 110mA on the +12V rail, which is a moderate footprint and power draw by modern Eurorack standards.
The 1050 does two jobs: an 8-input analog mixer and a step sequencer with eight playback modes. You can route eight separate audio or CV signals through the mixer section. Two adjustable outputs allow dual submixing, or you can treat it as two independent 4-input mixers. That makes it useful beyond sequencing, especially in complex patches with several signal blends. The sequencer doesn't run on its own. Owners report needing to mult a steady clock signal to start step progression. It has two manual gate buttons for triggering by hand, but only one 1/8" TS input for external clock or gate control, which some users find limiting.
The 1050 doesn't copy the ARP 2500's patching approach exactly. It is adapted for modern Eurorack norms, with 3.5mm jacks and normalized power distribution. It was confirmed to be in production by late 2021, and early forum chatter suggested users were looking forward to it. Some builders welcomed it as a budget-conscious take on classic modular design. Others found its logic non-intuitive. One owner connected it to the Behringer 1028 envelope follower but ended up selling it because of awkward operation. Others praised the general functionality and price point across the 2500 Series.

Key Features
8-Channel Mixer with Dual Output Modes
The Behringer 1050 lets you combine eight separate signals - audio, CV or gate - into one mix. According to Modern Musician, it can run as a single 8-input mixer with two independently adjustable outputs, which allows stereo routing or parallel processing. It can also be split into two isolated 4-input mixers, which helps in dense patches that need several mix points. That makes it more versatile than a fixed-configuration mixer, especially in systems without spare mixing modules.
Step Sequencer with Eight Playback Modes
As a sequencer, the 1050 offers eight playback modes, though documentation on their exact behavior is sparse. It does not run autonomously. You have to supply a clock signal through the single 1/8" TS gate/clock input to advance steps. Because of that external clock dependency, it can't serve as a standalone rhythmic core without other modules. The two manual gate buttons allow live triggering or step skipping. With only one clock input, complex synchronization setups are limited.
Single Gate/Clock Input
The module has only one 1/8" TS input for gate or clock signals. That simplifies the front panel but restricts integration. In systems where multiple clock sources or reset triggers are common, this single input may need passive multing or buffering to distribute signals from a master clock. Forum users have noted that the sequencer function demands a steady clock mult, which indicates it has no internal timing circuitry or tap-tempo function.
Historical Context
The Behringer 1050 Mix-Sequencer is a modern reinterpretation of a module from the ARP System 2500, an analog modular synthesizer produced from 1970 to 1981. The System 2500 was known for its flexible matrix-based patching and distinctive sound, and was used by artists ranging from Devo to Giorgio Moroder. Behringer's version is part of its 2500 Series Eurorack line and aims to bring that architecture to contemporary modular users at accessible prices. Production of the 1050 was confirmed to be underway by late 2021, following earlier announcements of "production soon" in user forums.
Collectibility & Value
Retail pricing for the Behringer 1050 was listed at $88.90 (USD) by Altomusic, with forum speculation suggesting an expected MSRP range between $49 and $99 at launch. It is a recent production item based on vintage designs, so it has not entered the vintage collector market in any significant way. Its value stays close to retail, with no notable premium or depreciation reported. User experiences vary. Some appreciate the functionality and price, while one Mod Wiggler user found the operation non-intuitive and sold it after pairing it with the 1028 module. No common failures or maintenance issues have been documented in available sources.
