Description

Unleash the sonic power of a bygone era with the Behringer Cat Duophonic Synthesizer, an homage to a cult classic that captivated musicians in the mid-1970s. This agile beast purrs with analog warmth, boasting dual VCOs that deliver a versatile palette of sounds from rich, warm basslines to searing leads. Whether you're a seasoned synth aficionado or a budding sound designer, the CAT promises a journey of discovery with its four mixable waveforms—sawtooth, triangle, modulated pulse, and sub-octave square—that provide endless sonic possibilities.

Critic Reviews

Behringer Cat review | Juno Daily

juno.co.uk

Behringer’s Cat synthesizer stands out with its quirky design and rich sound, channeling a nostalgic vibe while offering modern enhancements. The dual-oscillator setup delivers thick, warm tones, and the extensive modulation options allow for a broad sonic palette, making it a versatile tool for any musician. However, its less recognizable sound compared to iconic synths might leave some users wanting more familiarity. While the quirky features and flexible connectivity are refreshing, they may feel unconventional to those accustomed to mainstream models. Overall, the Cat is a unique offering that rewards exploration—just don’t expect it to steal the spotlight from its more famous counterparts.

Wonderful Sound!

This thing sounds smooth as warm butter. Creamy, bold, and has a great mouthfeel. Wait, don't eat it. Not that I'm in a position to tell you what to do with your life. But if you like analog synthesizers you should get this one.

It's analog so it can and will go out of tune. It has no patch memory.

That's all of the positives I can think of. As for the negatives, there are none.

Excellent clone

Can do clean, can do dirty, sample and hold functions are great. Mixing waveforms is really good, 3 different sync modes, can modulate VCO1 with VCO2 and/or vice versa, nice little patch bay, and dedicated noise mixer as well. The original Octave CAT is not in production anywhere else.

Glad you're digging this. I remember reading an article in SOS (or similar) years and years ago where someone reported hearing an Octave CAT make a sound just like shattering glass... which has always had me curious about owning one someday.

fun little synth, weirdly flexable but an unstandard layout

basically what i said in the title, overall great, fun new addition to the collection. as well as the multiple outputs for patchign is great
