CorOS 2.0.0 is now available

CorOS 2.0.0 is now available. Download it via Settings > Device Options > Device Updates on your Quad Cortex once connected to Wi-Fi. We recommend that you create a backup before updating your firmware. The user manual has also been updated, as has the Windows driver.

Added

Hybrid Mode

You can configure a Hybrid Mode via the new “Modes configuration” option on the Main Menu. It allows you to assign a separate mode to each row of footswitches. Hybrid Mode is ideal for people who want to quickly access new Presets while having granular control within their active Preset by incorporating Stomp Mode or Scene Mode. You can create a Hybrid Mode out of any of the three available modes. Additionally, you can remove modes you don't use to toggle between 3, 2, or even just 1 active mode. 

Cab/IR Global Bypass

It is now possible to globally bypass Cabs, IR Loaders, or Neural Captures of cabs on any rows. Globally bypassed devices will be indicated with a bypass icon on The Grid but will not be greyed out.

Global EQ

A global EQ has been added to Out 1/2 and Out 3/4, and is available via the I/O Settings screen. Tap the EQ button on the I/O Settings screen to open a 5-band parametric EQ that you can assign to either Out 1/2, Out 3/4, or both pairs of outputs.

Master Volume Knob Assignment

It is now possible to configure which outputs the Master Volume Knob controls via the Device Options screen. The level of Send 1/2 is only controlled by the Master Volume Knob when they are being used as outputs and not when they are being used in an FX Loop block on The Grid.

Gain Reduction Meter

A gain reduction meter has been added to the parameter editor of all Compressor devices except the Jewel and Chief CS3.

Device Versioning

Device Versioning has been added to allow users to select the version of a device they want to use. This allows us to non-destructively provide new versions of devices where their performance has changed or sound has been improved.

If an update for a device you are using is available, a green icon will display in the top-right corner of its icon on The Grid. In addition, the first time you open the parameter for a device with an update available, the contextual menu button will change to a green arrow. 

You can switch between updated and legacy versions of a device via the contextual menu in the parameter editor.

Tap Tempo Scene Change

A Scene change button has been added to the Tap Tempo screen allowing you to configure the tempo of each Scene without having to exit the Tap Tempo screen.

Scene Bypass State Behavior

It is now possible to control whether the bypass state of blocks in Scenes is saved when changing its bypass state in Stomp Mode, Hybrid Stomp Mode, via MIDI, or via the touchscreen. This setting is accessed via the Device Options screen.

IR Loader

An IR Loader block has been added. With an IR Loader block added to The Grid, you can tap the Impulse Response section of the block to browse the IRs on your QC. Once an IR is loaded, you can use the parameters at the bottom to modify its sound. 

Four different types of the IR block are available: Single (M), Single (ST), Double (M), and Double (ST). The Double IR Loader blocks allow you to load two IRs and control them independently. You can also add an IR Loader block by tapping an IR in the Directory. This will load Single (M)ono block by default.

Changed

Directory

The Directory has been completely redesigned. We’ve implemented several changes to help search, filter, and categorize items to make it quicker and easier to find what you’re looking for.

Presets, Neural Captures, and IRs are now broken into separate categories in the Directory, and each category can easily be collapsed or expanded on the left-hand side. The banks column has been shrunk to allow the right column to be bigger to accommodate new buttons for uploading and to make longer filenames easier to read.

The number of Captures you are able to store in the My Captures folder has been increased from 1024 to 2048. The number of user-storable Impulse Responses remains at 1024. The number of user-creatable Setlists remains at 11, in addition to the “My Presets” Setlist, for a total of 3,072 user Presets.

The swipe left to edit functionality has been removed from items in the Directory and replaced with a contextual menu button that reveals editing functionality. A contextual menu has also been added to Setlists allowing you to edit or delete them.

When saving an item, the editor UI has changed to make use of more of the screen. A bigger and more responsive keyboard has been added. The blue button at the top-right takes you to the next step where it is possible to add additional metadata. You can also tap the file location box to change the save location, or tap the metadata icon next to the name to move forward to the metadata page. 

Tags have been removed from the save UI on Quad Cortex, but can still be added to items on Cortex Cloud/Mobile.

When scrolling to the top or bottom of a bank of Presets, the next bank shows above/below so you can continue scrolling, and the bank automatically changes in the middle column.

Scrolling performance has been improved, providing a smoother and faster response. 

A scroll jump section has been added on the right-hand side, allowing you to jump to sections of your filtered results.

Banks have been removed from Neural Captures and replaced with a more robust sorting & filtering system, as well as the brand new Search.

Sorting options have been added to the Directory as well. Neural Captures can be sorted by Name, Date added, Author, Preferred instrument, Capture type, and Gain. You can tap an option a second time to change between ascending and descending order.

When sorting, the Reference box allows you to change the information displayed in the list of sorted results.

Tapping a Capture in the Directory immediately displays The Grid and shows all of the available spaces where the Capture can be added.

Furthermore, two arrows will display above any block that you can switch with the selected Neural Capture. The arrows will only display above blocks where there is enough CPU available to switch the devices.

Like with Captures, Presets can be sorted. “Banks” is now a sort option, so if you sort by anything else, your Presets will display in a list rather than in banks.

Banks have also been removed from Impulse Responses, and instead they are displayed in a long list with sorting options.

IRs with long names have the middle of their names truncated so that the beginning and end of the filename is visible, making them easier to read.

The interactions with Cortex Cloud have undergone some significant changes, and several quality-of-life improvements have been made.

When uploading Presets or Neural Captures, instead of dragging-and-dropping each item to the top of the screen, you now toggle Upload Mode with the button at the top-left.

With Upload Mode toggled, simply tap the Upload button next to each item and it will upload in the background. Press the Upload Mode button again to exit. Items will continue to upload in the background even when you’ve exited Upload Mode.

We’ve removed the Starring system completely, and instead items can just be downloaded.

Once you have added items to your download queue on Cortex Cloud/Mobile, when you open a Downloads folder and your Quad Cortex is connected to Wi-Fi, the items will begin downloading immediately.

Once Presets have downloaded, they live in your Downloads folder until they are either moved to a Setlist or deleted.

If you would like to move a Preset from your Downloads folder to a Setlist, tap the Save & Move button. From here you can browse your Setlists (or create a new one) and choose where you would like to save the Preset. Once saved, you will be taken back to the Downloads folder.

Presets can be auditioned directly from the Downloads folder; just tap a Preset to load it onto The Grid.

Downloading and managing Neural Captures works very similarly to Presets, however tapping the Save & Move button will simply move the Neural Capture to the My Captures folder, since there are no banks or Setlists to manage for Neural Captures. 

When saving a Preset that has Bundled Captures, the Captures will be moved to the My Captures folder when a Preset is moved to a Setlist.

Preferred Instrument

You can now specify a preferred instrument for your Preset or Neural Capture. This metadata can be used when searching/sorting on Quad Cortex and on Cortex Cloud/Mobile.

Capture Types

When creating/editing a Neural Capture, you can now specify a Capture Type. The complete list of Capture types includes Default, Amp Head, Amp + Cab, Combo Amp, Cab, and Pedal. Each Capture type has its own icon, and this icon will display on The Grid when the Capture type has been set.

It is also possible to add this metadata when editing a Preset on Cortex Cloud/Mobile.

Captures can be filtered by the range of Capture types in the Directory and on Cortex Cloud/Mobile.

Capture Gain

Gain is a metadata automatically calculated by Quad Cortex when creating a Neural Capture. Quad Cortex analyzes the sound produced by a Neural Capture and determines how saturated it is, giving it a ranking of 1-10; 1 being a clean tone and 10 being the most saturated/highest distortion.

All existing Neural Captures on Cortex Cloud have been automatically updated to have this metadata calculated.

Search

Search has been completely overhauled. Search now spans the entire screen. Recently searched terms are displayed beneath the text entry.

Search displays suggestions beneath the text entry as you type.

Search results are separated into categories & tabs for Presets, Neural Captures, and IRs. There are also subcategories for each of the locations where files can be found, and these can be collapsed or expanded by tapping the arrows on the right-hand side.

Tapping an item will take you to the file’s location in the Directory and highlight it. From there you can interact with the item, continue browsing the Directory, or tap the Search button to return to the search results.

Search results can be sorted & filtered (depending on the category selected), and all the relevant metadata is available to reference as required.

Cloud Backups

It is now possible to create up to 5 Cloud backups. You are also able to edit, update, or delete each backup.

Mute/Bypass

It is now possible to change the functionality of the bypass parameter to mute in a device’s parameter editor via the contextual menu. A muted device is indicated by a red line in the device’s icon on The Grid.

Capture Inputs

The inputs used to make a Neural Capture have changed from Return 1 & Input 1 to Input 1 & Input 2. When making a Neural Capture, you now connect your guitar to Input 1 and the target device to Input 2.

Factory Presets

All Factory Presets have been updated to incorporate new metadata and to use the new versions of updated devices. Furthermore, any Presets utilizing the Utility Gate block have been updated to use the Input Gate instead. A Looper has also been added to Presets that showcase amplifier models, and all Wah & Volume pedals have been mapped to EXP1 or EXP2 where appropriate.

WiFi MAC Address

The MAC address now shows on the Hardware Information screen.
