Description

The Behringer Kobol Expander is a nod to the iconic sounds of the 1970s, offering a modern twist on vintage analog synthesis. With its all-analog circuitry, this semi-modular synthesizer is designed to deliver a rich, duophonic experience. At its core are two highly adaptable VCOs, each capable of morphing between seven distinct waveforms, giving you the creative freedom to craft your ideal sonic landscape. Whether you're aiming for smooth sine waves or gritty sawtooth tones, the Kobol Expander has you covered.

For sound sculpting, the Kobol Expander features a 4-pole low-pass VCF that imbues your tones with natural warmth and saturation. The onboard LFO, offering triangle and square wave options, extends your modulation capabilities beyond the internal circuitry, allowing you to invigorate external synths and modules with rhythmic or gradual effects.

Connectivity is a breeze with the Kobol Expander's comprehensive I/O suite, which includes MIDI in and thru, USB-B, and multiple audio outputs. Its Eurorack-compatible design with 32 patch points takes modular integration to new heights, allowing seamless incorporation into larger setups. The Poly Chain capability enables you to link up to 16 units, unlocking massive 16-voice polyphony for those who crave expansive soundscapes.

Whether you're a seasoned synth enthusiast or a newcomer to modular systems, the Behringer Kobol Expander offers a universe of sonic possibilities in a compact, user-friendly package.

Sonic LAB: Behringer Kobol Expander Review

sonicstate.com

The Behringer Kobol Expander offers a delightful nod to vintage synthesis with its charming character and robust sound, particularly its impressive oscillators and resonant filter. While the budget build quality—featuring plastic knobs and a basic MIDI interface—might deter some purists, the flexibility with patch points and the overall fun factor make it a compelling choice for synth enthusiasts. At around £175/$199, it’s a worthy addition for those seeking a unique, modulate-able instrument without breaking the bank. Just don’t expect top-tier materials; instead, embrace its quirky charm and impressive low-end.

Behringer Kobol Expander – AMSynths

amsynths.co.uk

A solid homage to the original RSF Kobol Expander, the Behringer version boasts impressive sound quality and a range of features at a budget-friendly price. The unique variable wave shape VCOs and a smooth-sounding filter inspired by the SSM2040 chip are standout elements. However, the product's idiosyncratic control voltage standards and some inaccuracies in the user manual can be frustrating for users, making integration into standard Eurorack setups challenging. While it excels in performance, potential buyers should be aware of these quirks that might require some extra adaptation. Overall, it's a worthwhile addition for those seeking vintage sounds on a budget, but perhaps not the most user-friendly option out there.

Behringer KOBOL Expander Test: Klein, aber mächtig! • Wine & Synths

wineandsynths.de

The Behringer Kobol Expander showcases solid analog sound and impressive versatility with its semi-modular design, offering fat bass tones reminiscent of classic synths. Quick envelopes and a fun FM modulation feature add to its appeal, especially for those looking to explore sound design. However, for users already equipped with multiple modules, there may be some redundancy in sound, which is a slight drawback. Despite this, at a price under 200 Euros, it presents a compelling option for newcomers to hardware synthesis. Overall, it’s a worthwhile addition to any synth lineup, especially if you're eager to start twisting knobs and patching sounds.
