Behringer HALOS: Unlocking Hidden Dimensions in Modular FX

HALOS is introduced here not just as another effects processor, but as a module that opens up fresh territory for sound design. The presenter wastes no time in highlighting that, despite its straightforward exterior, HALOS conceals a wealth of features just beneath the surface. This isn’t simply about slapping reverb or delay onto your signal chain; it’s about unlocking new dimensions of timbre and modulation that can reshape how you approach your rack.

The video sets the tone by promising a journey into hidden modes and extra features, suggesting that HALOS rewards those willing to dig deeper. For modular enthusiasts, this is a familiar thrill: the joy of discovering what happens when you push past the obvious and start patching in unexpected ways. Behringer’s approach here is to make these discoveries accessible, with clear demonstrations and a focus on creative exploration.

Diving into the specifics, the video showcases HALOS’ polyphonic capabilities, including a newly revealed three-voice mode. This sits neatly between the more conventional dual and four-voice settings, offering a unique blend of overlapping voices for richer harmonic content. The activation is straightforward—hold the poly select button and watch for the LED to flash between amber and red, indicating you’re in the elusive three-voice territory. The resulting sound is described as lush, with the sympathetic strings engine producing harmonics and overtones that go well beyond the sum of their parts.

But HALOS isn’t content to stop at polyphony. The presenter uncovers a built-in two-operator FM synth engine, accessible via the modal synthesis mode. This engine, reminiscent of those found in other Behringer and Mutable Instruments modules, adds a whole new layer of timbral complexity. The FM mode is activated by a simple button hold, and the video demonstrates its ability to generate everything from metallic clangs to evolving textures. For those who like to push their modular setups into unexpected territory, this synthesis engine opens up a host of creative possibilities.

HALOS continues to reveal its secrets with the introduction of western chord modes for the sympathetic strings engine. By holding the engine selector, users can switch from the default tuning of perfect fifths and octaves to a mode where the structure control sweeps through various chord voicings. This feature is particularly handy for those looking to add harmonic movement or instant chordal textures without the need for external sequencing or complex patching.

The module also flexes its muscles with built-in effects, notably a reverb that can be added to the non-linear string engine. Engaging this effect is as simple as holding the select button, after which the reverb size is controlled by the dampening knob. This integration of effects directly into the synthesis engines means HALOS can serve as both a sound source and a processor, streamlining patch cables and opening up new creative workflows for modular users.

Performance examples throughout the video highlight how HALOS can slot into a modular setup, with the presenter using modules like Radar to trigger and modulate parameters for expressive results. The hands-on demonstrations show HALOS responding dynamically to everything from envelope triggers to rhythmic accents, underscoring its versatility as both an effect and a sound generator.

The pièce de résistance is the reveal of a hidden string machine engine, loosely inspired by the Roland RS09. Unlocking this Easter egg requires a specific combination of control settings, after which HALOS delivers lush, vintage string textures complete with three built-in special effects. The video closes by emphasizing HALOS’ value for both seasoned modular users and newcomers, positioning it as a module that rewards curiosity and experimentation in any Eurorack environment.
