The Essentials to Know About the Neural DSP Quad Cortex Multi-Effects Processor
- Ultra-powerful stage processor (4 SHARC+ + 2 ARM) for chaining multiple amps, stereo effects, and IRs without compromise.
- "Neural Capture" technology to learn and faithfully reproduce real amps, overdrives, and cabinets.
- Compact and robust format with 11 footswitches/encoders and a 7-inch touchscreen for immediate workflow.
- Comprehensive connectivity (XLR, TRS, effects loops, MIDI, USB) and Cortex Cloud integration for presets and IRs.
From Studio to Tour: Neural DSP's Flagship
Designed as the pinnacle of the range, the Quad Cortex combines amp modeling, impulse responses, and neural capture in a touring pedalboard. Its philosophy is rooted in the history of amp profiling, while pushing further the precision and playing feel thanks to massively parallel processing and biomimetic algorithms.
For Whom and For What Uses?
Ideal for demanding guitarists and bassists, from rock to metal, including modern blues, pop, ambient, or fusion. On stage, it integrates directly with a PA system or FRFR cabinet to preserve your amp and cabinet simulations. In the studio, it functions as an audio interface/USB device and effects hub, while effortlessly fitting on a pedalboard.
Key Features and Modern Workflow
The 7-inch touchscreen allows you to create, organize, and edit your scenes with a single gesture. The 11 footswitches also act as rotary encoders for quick foot adjustments. Two effects loops facilitate the integration of your favorite pedals. MIDI In/Out/Thru automates scenes, and the two expression pedal inputs control wah, volume, or pitch. Ultra-low latency USB audio handles re-amping and recording, while Cortex Cloud simplifies sharing presets, neural captures, and managing IRs. The unibody aluminum chassis guarantees reliability and compactness (29 x 19 x 4.9 cm, 1.95 kg).
Sound Quality
The Quad Cortex stands out with very natural dynamics, precise attack response, and wide stereo imaging. Neural capture reproduces the grain, compression, and speaker/mic interaction of your rigs, while the algorithm library (50+ amps, 50+ effects, 50+ IRs) covers textures from crystalline cleans to modern saturations, including immersive delays and reverbs. Transparent when needed, colored when desired, it reacts like a real amp under your fingers.
