Back in the 1970s, the Octave CAT SRM II was a cult favorite for its raw, duophonic growl, inspiring everyone from prog rockers to experimentalists with its fat analog tones. This faithful recreation brings that same beast back at a fraction of the vintage price, ready to roar in your setup today.
At its heart are two voltage-controlled oscillators pumping out mixable waveforms—sawtooth, triangle, modulated pulse, and sub-octave square—for seriously thick, complex sounds you can blend on the fly. A classic SSM 2044 low-pass filter with resonance handles the sculpting, modulated from multiple sources including a versatile LFO with sine, square, and sample-and-hold options, plus two analog envelope generators for VCF and VCA duties. You'll love the 47 hands-on knobs and switches for real-time tweaking, white noise generator, and audio input to process external signals, all packed into a sturdy desktop module that slides right into a 70HP Eurorack case. MIDI in/thru via USB and DIN, CV/gate ports, velocity sensitivity, and Poly Chain for up to 16-voice polyphony make it a modular powerhouse.
Players dig its immediate, no-menu accessibility and that authentic '70s bite—leads snarl, basses thump, and pads shimmer—though some note the build feels more budget than boutique. It's a steal for diving into paraphonic analog without breaking the bank.
