Knobula Poly Cinematic – 8‑Voice, 56‑Oscillator Polyphony in 12 HP

Knobula’s Poly Cinematic packs incredible polyphonic depth into a single 12HP module—bringing full synth voice functionality (oscillators, filter, envelope, reverb) into compact form.

🔧 Core Specs

• Polyphony: 8 voices, each with 7‑oscillator supersaw, 3‑osc square/pulse, and 3‑osc tonewheel organ engines = 56 oscillators total reddit.com+14knobula.com+14synthanatomy.com+14

• Filters: Single multimode filter per voice (low‑pass, high‑pass, notch) with cutoff, resonance, and envelope modulation controls controlvoltage.net+2perfectcircuit.com+2perfectcircuit.com+2

• Envelope: Dedicated ADSR panel—with a combined decay/sustain knob—to shape each voice

• Reverb: Built-in high-quality stereo 24-bit/96 kHz reverb perfectcircuit.com+4knobula.com+4controlvoltage.net+4

• Patch I/O: MIDI TRS, CV/Gate inputs for pitch, filter, and chord select (with eight chord memory slots)en.wikipedia.org+7knobula.com+7knobula.com+7

• Size & Power: Compact 12HP, draws ~70mA on both +12V and −12V railsperfectcircuit.com+4vintageking.com+4knobula.com+4

✅ Key Advantages

• Full polyphonic voice in one module—no need for multiple OSCs, VCAs, envelopes, or mixersreddit.com+14controlvoltage.net+14perfectcircuit.com+14

• Immediate tactile control—all parameters have dedicated knobs; minimal menu divingvintageking.com+3elevatorsound.com+3controlvoltage.net+3

• Chord memory & CV control—play layered chords mono‑phonically or sequence chords over CVvintageking.com+4knobula.com+4elevatorsound.com+4

• Compact yet powerful—12HP houses a full 8‑voice synth, ideal for space-constrained casescontrolvoltage.net+8knobula.com+8knobula.com+8

⚠️ Considerations

• Digital core, analog-style feel—oscillators and filters are digital emulations, though touted for rich analog character

• No velocity or aftertouch—CV/Gate only; dynamic expression depends on external sources

• Reverb included—great for pads/stabs, but lacks onboard modulation FX; external effects may enhance versatility

• Menu-free interface—mostly user-friendly, though some reported “menu-divy” controls for deeper functionsen.wikipedia.org+5en.wikipedia.org+5controlvoltage.net+5controlvoltage.net+1knobula.com+1

🌐 Community Feedback

Modular users praise its ease and sonic power:

“It’s a polyphonic wavetable VCO/synth that is quite powerful. I have it and love it, only downsides I ran into is that it’s quite menu divy.” en.wikipedia.org+10reddit.com+10modularsquare.com+10

The Poly Cinematic is a rare gem in the Eurorack world—an 8‑voice polysynth with full voice architecture (56 oscillators, filters, envelope, reverb), tight CV control, chord memory, and an uncluttered interface, all in just 12HP. For producers and performers craving rich pads, cinematic textures, and powerful chordal play, it’s a surprisingly compact powerhouse—assuming you’re comfortable with its digital engine and mono expressiveness.
