AIRSTEP Cortex Edition

"The Ultimate Wireless Foot Controller for Nano Cortex"

AIRSTEP Cortex Edition is the ultimate wireless foot controller for the Neural DSP Nano Cortex—delivering hands-free control of all 64 presets, effect and tuner toggles, tap tempo, Capture slot changes, and more, all at once.

No setup required—just plug and play. Ultra-stable and far more powerful than any MIDI footswitch, with real-time LED feedback showing your current preset, bank, and effect states, plus dual expression pedal support.

It transforms your Nano Cortex into a fully portable, performance-ready rig.

AIRSTEP Cortex gives you full hands-free control of the Nano Cortex—with instant, latency-free switching of all 64 presets, toggle all five effect slots and the tuner, tap tempo, and Capture slots entirely from your feet.

No configuration or MIDI knowledge required. Simply power it on and it connects wirelessly to your Nano Cortex with rock-solid stability. It offers deeper, more intuitive control than any MIDI foot controller, with real-time LED feedback showing your current preset, bank, effect states, and tempo at a glance—something MIDI controllers simply cannot provide.

It offers two Control Schemes to match your workflow. Both include Preset Mode for switching presets, changing banks, tap tempo, and tuning. Control Scheme A pairs Preset Mode with Effect Mode for direct effect on/off control, while Control Scheme B pairs Preset Mode with Scene Mode to switch between predefined effect on/off combinations—all instantly from your feet. Control Schemes and Scene Mode effect on/off settings are configurable in the dedicated "AIRSTEP Cortex" app.

With AIRSTEP, your Nano Cortex becomes truly live-ready—like its big brother, the Quad Cortex, but far more compact and portable.

Review

AIRSTEP and the Nano Cortex create a fully wireless rig. With Nano Cortex powered by a power bank and AIRSTEP delivering up to 300 hours on its built-in battery, you can play anywhere without a single cable.

Both devices stay linked through industrial-grade wireless stability, giving you a fully portable, cable-free setup that's exceptionally convenient for practice, recording, and live performance.

The Cortex Cloud App also remains fully usable while AIRSTEP is connected, allowing real-time editing and adjustments at any moment.

AIRSTEP Cortex features two expression pedal inputs that can control any parameter on your Nano Cortex in real time—volume, gain, wah, pitch, FX parameters, and more. Simply assign your preferred function in our dedicated app and shape your tone freely with your feet. Search for "AIRSTEP Cortex" in the App Store to learn more about expression pedal parameter assignments.
