Existing plugin license holders can load these virtual blocks straight onto the Quad Cortex grid, seamlessly blending them with native CorOS processors and Neural Captures. Every X-updated plugin in the Neural DSP catalog is now fully compatible with hardware units.

Workflow Breakthrough: Device Presets

Device Presets revolutionize how guitarists construct signal chains on Quad Cortex and Quad Cortex mini. While a traditional Preset saves an entire signal chain, a Device Preset stores individual virtual block configurations. Guitarists can now dial in a favorite drive, amplifier, cabinet, or spatial effect and instantly recall those exact settings inside any rig.

CorOS 4.1.0 includes over 2,000 Factory Device Presets crafted by the Neural DSP sound design team. Users can also store up to 32 customized User Device Presets per virtual block. These presets preserve parameter values, toggle states, and expression assignments while maintaining existing Scene settings.

Presets for I/O Settings and Global EQ

The Device Preset management system now extends directly to I/O Settings and Global EQ menus. Players can store and recall customized input/output routing profiles for studio recording, stage performances, and rehearsals without adjusting individual parameters manually.

Eight Brand New Virtual Devices

CorOS 4.1.0 introduces eight versatile processing blocks for Quad Cortex and Quad Cortex mini:

  1. Multivoicer (Pitch) — Advanced pitch-shifting engine adding up to four harmony voices with scale and MIDI pitch control. Ported from Archetype: Tim Henson X.

  2. Glitch (Morph) — Granular delay processor built for rhythmic stutter effects and experimental electronic textures. Ported from Archetype: Misha Mansoor X.

  3. Ring Modulator (Morph) — Metallic ring modulation designed for bell-like tones and aggressive metallic textures.

  4. Arpeggio Delay (Delay) — Multi-tap delay where individual repeats feature independent pitch shift and stereo pan positioning.

  5. Crystal Delay (Delay) — High-fidelity pitch-shifted delay creating pristine, shimmering ambient tails.

  6. Vintage Digital (Reverb) — Detailed physical modeling of the iconic OTO Machines® BAM Space Generator™ processor, complete with a dedicated Freeze control for infinite sustain.

  7. Douglas Shining Comp (M) (Compressor) — Studio-grade dynamic compression modeled after the renowned Darkglass Electronics® Hyper Luminal™ pedal.

  8. Plugin Parametric-4 — Precision four-band parametric equalizer featuring adjustable High-Pass and Low-Pass filters.

Dual Footswitch Assignments

Stomp Mode now supports Dual Footswitch Assignments, enabling secondary block parameters to be controlled independently of primary bypass states. For example, players can assign the Vintage Digital reverb bypass to one footswitch and assign its Freeze feature to another. Dual assignments are currently supported on Vintage Digital, Aeons Reverb (Rabea Massaad), and Laser (Misha Mansoor).
