Cortex Control features

Fully integrated desktop controller for Quad Cortex. Cortex Control lets you manage every feature and setting of your Quad Cortex effortlessly in a sleek and intuitive desktop interface.

Boots in seconds. Cortex Control boots in seconds and instantaneously syncs your Quad Cortex’s current state. Pick up where you left off without any interruptions in your workflow.

Optimized workflow. Intuitive mouse actions and keyboard shortcuts ensure that tweaking parameters, managing files, carrying out tasks, and navigating through Cortex Control is smooth and efficient.

Bulk actions. Copy, like, upload, download, or delete multiple Presets with a few clicks. Similarly, you can edit, upload, download, or delete multiple Neural Captures and IRs at once.

Local backups. Cortex Control lets you create and manage local backups of your Quad Cortex directly on your computer. You can create as many local backups as you need. Quick actions for renaming, updating, deleting, and recalling backups makes managing them quick and easy.

Internet via USB. Quad Cortex can access the internet using the USB cable it’s connected to your computer with. This ensures uninterrupted internet access for your Quad Cortex regardless of Wi-Fi availability. Quad Cortex will prioritize internet via USB when Cortex Control is open.

Import IRs. Adding IRs to your Quad Cortex or Cortex Cloud profile is streamlined with Cortex Control. Simply open your IR library and drag-and-drop your IRs into it. The IRs will be immediately available on your Quad Cortex or Cortex Cloud account, depending on which library you upload them to.

Live tuner. Stay in tune without having to open the tuner. Toggle the live tuner by holding CMD/CTRL and clicking the tuner button in the Utility Bar.

Audition devices. Click a device on The Grid and then click on another device in the Device List to audition it. Click the auditioned device again to add it to The Grid and replace the loaded device or press ESC to cancel the change.

Create Neural Captures. The full process for creating Neural Captures can also be completed on Cortex Control.

Cortex Control known issues

Directory folder structure and all local Presets, Captures, and IRs are not updated correctly on Cortex Control after downloading a backup. Restarting Cortex Control is required.

A device that has been copied while in the "Mute" state will be pasted in the "Bypass" state when pasting that device to an empty slot on The Grid.

A device that has been copied while in the "Bypassed" state will be pasted in the 'Enabled' state after pasting the device to an empty slot on The Grid.

A UI crash occurs when changing a Preset using the Up/Down arrows during a Cloud Backup.

Cortex Control will not re-sync with the Quad Cortex after both Control and the Quad Cortex are idle for a period of time.

Renaming a user-created Setlist on the Quad Cortex while the Preset Explorer menu is open and a Preset from that Setlist is active will cause Cortex Control and the Quad Cortex to crash.

New footswitch and EXP MIDI assignments made in Cortex Control’s Preset MIDI Out menu cannot be previewed while the Preset MIDI Out menu is open on Cortex Control.

Searching for an item located in Downloads could lead to a crash.

The 'Swap' option is displayed in the contextual menu for any copied Preset after the Preset has already been pasted or swapped to a different slot in the Directory.

The Preset MIDI Out 'Preset load message' sub-menu is not in sync on either Cortex Control or Quad Cortex.

In Gig View, while in Hybrid (Scene + Stomp Mode) Mode, assigning a device to a new footswitch is not immediately updated on the Quad Cortex.

'Prev Row' indicator is not removed in Cortex Control when modifying an Output that was previously routed to another row.

Changes to the Tuner input drop-down menu aren't reflected on the Quad Cortex while the Tuner is open on the Quad Cortex.

There is no way to tell when a Neural Capture has been queued for download within the Neural Captures downloads folder in the Directory.

There is no way to tell when a Preset has been queued for download within the Presets downloads folder in the Directory.

The yellow missing Impulse Response indicator will be displayed on any device icon after changing the type of an existing device on The Grid in a certain way.

If a device is copied/pasted on the Quad Cortex, the device will not show that it has Scenes assigned to its parameters when viewing The Grid on Cortex Control.

When copying and pasting a device with parameters assigned to Scenes, the pasted device will not initially show the correct parameter values.

When creating a Neural Capture, the Cabsim doesn't recall its previous state when closing and reopening the “New Neural Capture” menu unless it's also open on the Quad Cortex.
