Added

Stomp Mode Bypass

You can now assign the bypass status of multiple devices to one footswitch in Stomp Mode. There is no limit to the number of devices’ bypass status that can be assigned to a single footswitch.

Input Gate

An Input Gate is available on all Input Blocks. It is bypassed by default when creating a new Preset and on all existing Presets.

Boot Splash Screen

A new boot splash screen has been added.

Recovery Mode

Press and hold the A and H footswitches within the first 6 seconds of the splash screen displaying to initiate Recovery Mode, where you can reset the settings or perform a factory reset.

Swap Scenes

You can now swap one Scene’s footswitch with another via the Main Menu on The Grid. This action can be performed in any Mode.

Text Cursor

You can now change the position of the caret in any text field by rotating the UP ARROW footswitch.

Numeric Keyboard

A numeric keyboard has been added.

USB Dry/Wet Signal

It is now possible to change which USB ins/outs send the dry or wet signal when using the Quad Cortex as an audio interface.

Minivoicer

Our intelligent Minivoicer algorithm allows you to add 2 pitch shifted voices on top of your signal.

The voicing library provides absolute control over the root note, modes, and chords for harmonizing as well as arpeggiating. Activate MIDI to receive MIDI chords or notes which will harmonize your DI signal to the MIDI-instructed pitch.

The Minivoicer is available within Pitch devices.

An issue where new default parameters could not be saved after previously changing and saving new default parameters for a device.

An issue where the Tempo value would be slow to adjust when the Tempo was set to Global.

An issue where there would be a noticeable lag when assigning a Wham block to an expression pedal and pivoting the expression pedal from toe to heel then back again quickly.

An issue where Scene data was not retained for parameters assigned to Scenes after assigning and then unassigning those parameters to an expression pedal.

An issue where all footswitch LEDs would be illuminated within all Settings sub-menus after navigating away from the Brightness menu.
