XSONIC AIRSTEP CTX Edition - The Ultimate Foot Controller for Nano Cortex

The XSONIC AIRSTEP CTX Edition is a dedicated wireless foot controller for the Nano Cortex, giving you complete hands-free command of all 64 presets, effect slots, tap tempo, tuner and more. With zero setup, rock-solid wireless performance and up to 300 hours of battery life, it turns your Nano Cortex into a fully portable, live-ready rig that feels as immediate and flexible as a full-size Quad Cortex.

Designed specifically for Nano Cortex users, AIRSTEP CTX removes the usual MIDI headaches. Just power it on and it auto-connects, with ultra-stable wireless communication and no noticeable latency. Real-time LED feedback mirrors your current preset, bank, effect states and tempo, so you always know exactly what your rig is doing, even on a dark stage.

Two flexible Control Schemes let you tailor the workflow to how you play. Switch presets and banks, toggle individual effects, call up scenes with predefined combinations, tap tempo and access the tuner, all from your feet. Dual expression inputs unlock continuous control of volume, gain, wah, pitch or any assignable parameter, letting you shape your sound in real time without ever touching the Nano Cortex itself.

With its rugged extruded aluminium housing, rechargeable long-life battery and full compatibility with the Cortex Cloud App, AIRSTEP CTX is built for serious players who want compact, cable-free control without sacrificing professional flexibility.

Zero Setup, Total Control

AIRSTEP CTX gives you instant, latency-free control of all 64 Nano Cortex presets, all five effect slots, tap tempo, tuner and Drive and Mod type changes directly from your feet. There is no configuration or MIDI knowledge required; simply power it on and it connects wirelessly to your Nano Cortex with rock-solid stability, delivering deeper, more intuitive control than a traditional MIDI footswitch.

Flexible Control Schemes and Scenes

To suit different playing styles, AIRSTEP CTX offers two Control Schemes. Both include a Preset Mode for switching presets, changing banks, tapping tempo and accessing the tuner. Control Scheme A pairs Preset Mode with Effect Mode for direct on or off control of each effect slot, while Control Scheme B pairs Preset Mode with Scene Mode so you can recall predefined combinations of effect states in an instant. Control Schemes and Scene Mode settings are configured via the dedicated AIRSTEP Cortex app.

Fully Wireless, Fully Portable Rig

Used together, AIRSTEP CTX and the Nano Cortex can form a completely wireless setup. With the Nano Cortex powered by a suitable power bank and AIRSTEP running on its built-in rechargeable battery for up to 300 hours, you can rehearse, record or perform without a single control cable. Industrial-grade wireless stability keeps both units locked together, while the Cortex Cloud App remains fully usable for real-time editing even when AIRSTEP is connected.

Dual Expression Pedal Inputs

Two expression pedal inputs give you continuous, real-time control over virtually any Nano Cortex parameter. Assign volume, gain, wah, pitch or specific effect parameters in the AIRSTEP Cortex app, then shape your tone dynamically with your feet. Whether you need subtle swells, expressive filter sweeps or precise pitch shifts, the dual expression support makes your compact rig feel like a full-featured pedalboard.

• Hands-free Wireless Control for Nano Cortex - Operate all 64 presets, all five effect slots, tap tempo, tuner and Drive and Mod type changes entirely from your feet, with no noticeable latency. This frees your hands for playing and makes the Nano Cortex feel like a true performance hub rather than a desktop unit.
• Zero Configuration, Deep Integration - Simply power on AIRSTEP CTX and it connects wirelessly to your Nano Cortex, with no MIDI setup or programming required. Real-time, auto-synchronised LED feedback shows your current preset, bank, effect states, scene and tempo, giving you clear visual confirmation that standard MIDI controllers cannot offer.
• Two Control Schemes with Scene Mode - Choose between a workflow focused on individual effect toggling or one built around scenes with predefined effect combinations. This flexibility lets you adapt AIRSTEP CTX to anything from simple preset stepping to complex live sets with multiple sounds per song.
• Dual Expression Pedal Inputs - Connect up to two expression pedals and assign them to volume, gain, wah, pitch or other parameters via the AIRSTEP Cortex app. This adds a powerful, expressive layer of control to your Nano Cortex, turning compact rigs into highly responsive performance setups.
