Neural Capture is a powerful tool that can learn and replicate the sonic characteristics of any amplifier, cabinet, or overdrive pedal with unprecedented accuracy and realism.

Creating a new Neural Capture is a procedure that can be completed on Nano Cortex without using the Cortex Cloud app.

To create a Neural Capture, you need to be able to connect an overdrive pedal, mic up a cabinet, or connect an amplifier via a reactive load box.

Neural Capture is a snapshot of a real device setup including the microphone, therefore the placement of the microphone with respect to the cabinet is also something you need to consider.

Nano Cortex's CAPTURE INPUT supports dynamic microphones. Condenser microphones will need an external preamp to be powered.

Press CAPTURE to access Capture Mode. In this mode, the CAPTURE LED ring will stay on.

Press EXIT to return to Performance Mode.

OVERDRIVE PEDAL

If you are capturing an overdrive pedal, connect its output directly to the Nano Cortex's CAPTURE INPUT.

AMP+CAB / COMBO AMP

Position a microphone in front of the speaker cabinet and connect it to Nano Cortex's CAPTURE INPUT. Nano Cortex's CAPTURE INPUT supports dynamic microphones. Condenser microphones need an external preamp to be powered.

AMP HEAD (NO SPEAKER)

If you are capturing an amplifier without built-in speakers or just an amp head, connect the amp's 'Speaker Output' to a Reactive Load Box. Then, connect the Load Box's balanced output to the Nano Cortex's CAPTURE INPUT.

05 SETUP REVIEW

Once everything is connected correctly, you can proceed with the calibration settings.

Capture Mode will give you access to the calibration settings.

Ensure the microphone position (if you are using a microphone in front of a speaker cabinet) and the target device's settings are set as desired, and the GAIN knob on the Nano Cortex is at the minimum position (0%).

• GND SWITCH: Toggles ON/OFF the ground lift on OUTPUTS 1L and 2R. This feature helps to reduce unwanted noise by interrupting the ground loops coming from external sources.

• BOOST SWITCH: Toggles ON/OFF the analog boost circuit. When enabled, it boosts the CAPTURE INPUT +26dB.

• • •

GAIN KNOB BEHAVIOR

In Capture Mode, the GAIN LED ring is a meter that measures the CAPTURE INPUT.

• The GAIN LED ring will turn green when the CAPTURE INPUT level is healthy.

• The GAIN LED ring will turn blue when the CAPTURE INPUT level is too low. Increase the GAIN or turn on the BOOST switch to compensate for the low level.

• The GAIN LED ring will turn red and blink when the CAPTURE INPUT level is clipping. Turn off the BOOST switch or reduce the output level of the target device until the signal level is correct (Green LEDs).

Press-and-hold CAPTURE for 3 seconds to begin the Capture process. Alternatively, press EXIT to return to Performance Mode.

The CAPTURE LED ring will light up progressively as soon as the process begins. The Capture process takes around 5 minutes.

The Nano Cortex will measure the latency of the target device and deliver recorded signals that will be used for modeling. After the sanity check, Nano Cortex will train a neural network to emulate the tone and dynamic response of the target device.

Once the training process is complete, you will be able to test and save your Neural Capture.

Once the Capture is completed, you can A/B compare the Capture and the target device.

EXPRESSION PEDAL SUPPORT

Nano Cortex is compatible with any expression pedal that meets the following requirements:

• TRS CONNECTOR: Single TRS expression output. Wah or Volume outputs are not supported.

• CURVE: Pedals with linear and logarithmic curves will work properly after being calibrated during the first use.

• TOE-SWITCHES: Optional feature. Latching and Momentary switches are supported. Momentary switches will work only when the Nano Cortex Latching Emulation feature is active.

• ADDITIONAL CONTROLS: Optional feature. Range control knobs and polarity switches are also supported.

Nano Cortex's operating system is called NanOS. Keeping NanOS up to date improves the functionality, security, and overall user experience of your Nano Cortex.

Ensure that the Nano Cortex is properly paired with your smartphone and that your Internet connection is stable.

UPDATE PROCESS

A banner will appear at the top of the app screen whenever a NanOS update is available.

1. Tap Update at the right side of the banner.

2. Follow the instructions on screen. Tap UPDATE to start the download process.

Nano Cortex's BANK and CAPTURE LEDs will reflect the download progress. Once the download completes, please wait a few minutes for your Nano Cortex to finish the installation.

After the setup, Nano Cortex will reboot and automatically reconnect to your smartphone.

The Settings screen allows you to control most aspects of your Nano Cortex.

Tap the contextual menu button at the app's upper-right corner and tap 'Settings' to access the Nano Cortex Settings screen.

NANO CORTEX SETTINGS SCREEN

• DEVICE NAME

Assign a custom name for your Nano Cortex (up to 22 characters).

• STORAGE

Available storage on your Nano Cortex.

• LED BRIGHTNESS

Drag the slider to set the LED brightness of your Nano Cortex (60% by default).

• PRESET OPERATION MODE

Enable 4-Preset Mode to assign Presets to both Footswitches I and II (IA, IB, IIA, and IIB).

If this setting is disabled, Nano Cortex will operate in 2-Preset Mode, allowing only Footswitch I to recall Presets (A and B) while Footswitch II will function as a global bypass switch.

• KNOB OPERATION MODE

By default, the Nano Cortex knobs adjust parameters immediately when turned. If this setting is disabled, Nano Cortex will operate in Latching Mode, where the knobs' position must match the values indicated by the LED rings before they start adjusting parameters.

• EXP/MIDI INPUT BEHAVIOR

Tap to toggle the EXP/MIDI Input functionality between MIDI and Expression Pedal.

• ABOUT

Current NanOS version and device serial number. The Nano Cortex serial number is also engraved on the bottom of the device.

• FACTORY RESET

Performing a factory reset will remove all user content from the device.

Nano Cortex can be utilized as a USB 2.0, 24-bit, 48kHz (Fixed), low-latency audio interface for Windows® and Mac® computers.

Connect your Nano Cortex to your computer via the USB-C cable included in the box.

MACOS® SETUP

1. Connect your Nano Cortex to your computer.

2. Go to 'System Preferences', 'Sound', and set Nano Cortex as the main Input and Output device of your computer.

3. Set the monitoring volume via the computer audio controls.

WINDOWS® SETUP

1. Download the driver installer from our website (Downloads).

2. Run the installer. Reboot your computer after the setup.

3. Connect your Nano Cortex to your computer.

4. Go to 'Control Panel', 'Hardware and Sound', 'Sound', and ensure your Nano Cortex is set as the default Playback and Recording device of your computer.

5. Set the monitoring volume via the computer audio controls.

The Nano Cortex driver will be installed in the following path location: C:\Program Files\NeuralDSP\Nano Cortex Driver

Nano Cortex features 7 USB Channels (4IN/3OUT).

D.I. and processed signal recording

Nano Cortex allows you to record dry and processed signals simultaneously. Connect your instrument to INPUT and ensure Nano Cortex is selected as the default audio interface on your computer.

1. Open your DAW, create a mono audio track, and set its input as Input 1 (Dry input signal).

2. Create a stereo audio track and set its input as Input 3/4 (Processed signal from analog OUTPUT 1L and 2R).

3. Arm both tracks for recording.

4. To reamp a recorded D.I. track, set its output as Output 3 (To Nano Cortex's INPUT), create a new stereo track (Input 3/4), and arm it for recording.

Connecting Nano Cortex to an iPhone® or iPad®

You can use any class-compliant USB audio device with an iPhone® or iPad®. Nano Cortex can be connected to those devices via a USB-C cable (iPhone 15 or later).

iPhone 14 and older generations will need the Apple® Lightning to USB-C Camera Adapter to recognize Nano Cortex as an external microphone device.

This feature allows you to use Nano Cortex with audio apps like GarageBand® for recording purposes.
