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.
Explore its duophonic and paraphonic modes to breathe new life into your compositions, allowing you to play two notes simultaneously or stack oscillators for a fuller sound. The CAT's gritty white noise generator and sample-and-hold unit add layers of texture, perfect for crafting those dystopian soundscapes. The self-oscillating resonant filter ensures you can shape your tones with precision, while the attack/release transient generator adds a unique character to each note.
For the modular enthusiasts, the CAT fits seamlessly into any Eurorack setup and offers extensive connectivity options, including USB-MIDI and 5-pin DIN, making it a versatile addition to any studio or live rig. With Behringer's Poly Chain capability, expand your soundscapes by linking up to 16 synths for monumental polyphony. Dive into the CAT's world and let its vintage charm and modern features inspire your next masterpiece.

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.
