From Now On, You Only Need One Controller

Comprehensive MIDI functions

AIRSTEP has comprehensive and powerful MIDI control functions. It has 2 5-PIN MIDI output interfaces, 1 Bluetooth MIDI interface and 1 USB MIDI interface. Together, they can control all the MIDI-related devices and effects apps at the same time. AIRSTEP can be placed on a pedalboard, next to a synthesizer stand, or under computer desk, and can easily be carried with a mobile phone or tablet.


AIRSTEP can send all types of MIDI messages, Control Change, Program Change, Note On/Off, SysEx, Real Time, etc. You can send up to 8 different MIDI messages at a time when you press each switch, which means that each switch can control up to 8 different MIDI devices, all at the same time. All the required MIDI messages can be easily edited through the AIRSTEP APP, and stored as presets. You can edit and store countless presets in the companion APP, and load AIRSTEP with one click whenever you want. There are a large number of factory presets already in the APP, which can meet the control needs of most of your gear.


AIRSTEP also has a powerful MIDI forwarding function. It has a traditional MIDI input interface, Bluetooth and USB can also be used as MIDI input. All MIDI input messages can be forwarded to any MIDI output interface, which means connecting your traditional MIDI keyboard or controller to AIRSTEP, they immediately become a wireless MIDI device, AIRSTEP can also forward a MIDI message sent from your computer or mobile phone to your hardware effector to switch presets.



What is AIRSTEP?


AIRSTEP is a universal foot controller that offers unprecedented flexibility and control of your music related devices and effects app ecosystem.


AIRSTEP can control hardware effects and amplifiers with MIDI input, and can also be used as traditional relay footswitches to control amps and effects without MIDI interface. AIRSTEP can control DAW and effect apps in a mobile phone, tablet or computer through Bluetooth, and even turn your traditional MIDI controller into a wireless controller.


AIRSTEP can be used as ”a computer keyboard placed on the ground”, it can control the page turning of tabs or music scores on the computer, tablet or mobile phone. When you watch video guitar lessons on a website, it can also control the pause, playback speed, and the transport controls of the video. Free your hands completely!


AIRSTEP has 5 footswitches, and can wirelessly expand 5 more footswitches. Each step on the footswitch can send up to 8 different control messages at one time. All control messages can be easily edited through the free AIRSTEP APP. Programming and editing isn’t your thing? Just load any of the massive library of built-in app presets with just one click. You can find the controller presets of your favorite gear right inside the APP, truly plug and play!


AIRSTEP is powered by a built-in rechargeable battery, no external power supply is required. Its compact footprint and sturdy metal casing is built to meet the most stringent environments faced by working professional musicians.







Smart Multi Controller

Computer keyboard on the ground

AIRSTEP can send HID messages via Bluetooth. HID messages are actually messages sent by a computer keyboard, so you can use AIRSTEP as a wireless keyboard placed on the ground. You can map any key value on the keyboard to the AIRSTEP's footswitches. Pressing the footswitch your foot is equivalent to pressing the key on the keyboard. When you are playing guitar while watching video lessons, practicing, covering, or recording, you always need to stop playing and use your hands to control the pause, playback, fast forward, rewind, or page turning of the music. Now, all of these can be controlled with your feet, and you can finally concentrate on your performance!


​​​​​​​All the key values on the computer keyboard can be mapped to any step on the AIRSTEP through the APP. As with MIDI messages, up to 8 different HID messages can be sent by one footswitch.



Traditional Relay Footswitch

AIRSTEP can be used as traditional relay footswitches to control amps or stompboxes with traditional relay footswitch interface. As long as your device can be connected to an ordinary foot switch, it can be connected to 4 RELAY interfaces of AIRSTEP to achieve the functions of amp channel switching, toggle effects, tap tempo, and even can be used as the sustain pedal of keyboard instruments. Similarly, you can use the mobile phone APP to edit RELAY control parameters for footswitches.



5 Footswitches and 5 wireless Footswitches

AIRSTEP has 5 footswitches, each footswitch can send up to 8 different messages to the specified output interfaces at a time, and the output message type can be any combination of MIDI, HID, and RELAY messages. AIRSTEP has three trigger modes: press, long press, and release. Each trigger mode can be assigned different message outputs to achieve the most flexible control. You can short press the footswitch to toggle effects, long press the same footswitch to switch presets, or you can press to open and hold on boost until the pedal is released. Footswitches can also be set to toggle mode. In the same trigger mode, the first trigger and the second trigger can send different messages. All these functions can be easily edited and stored through the mobile APP.


If 5 footswitches are not enough, you can also connect AIRSTEP Lite wirelessly and expand to a total of 10 footswitches. The extended 5 footswitches have the same assignable functionality and they are connected wirelessly! The wireless footswitches can control all devices connected to AIRSTEP!



APP Editing

All the parameters may be edited using AIRSTEP APP. There is no editing method that is more intuitive and convenient than the mobile APP! AIRSTEP APP connects to AIRSTEP via Bluetooth and displays its working status in real time. All parameters are stored in presets. The APP can store a limitless number presets as you want and you can load them into AIRSTEP with only one click. AIRSTEP can store the 5 most commonly used presets locally, and can also be used when no APP is connected. The AIRSTEP APP supports iOS/Android and may be downloaded from the Apple App Store or XSONIC official website. (To explore this free APP in advance, you can search “AIRSTEP”in App Store or Google Play)



USB HOST is a unique feature of AIRSTEP. It is equivalent to the USB interface on the computer. Devices that can be connected to the computer USB around you can also be connected to AIRSTEP. For example, AIRSTEP can connect and control multi-effect processor such as ZOOM MS Series with only the USB interface, or you can connect a USB MIDI keyboard to directly supply power to it, and upgrade it to a wireless Bluetooth MIDI Keyboard through AIRSTEP's powerful MIDI forwarding function.




MIDI Trigger

MIDI trigger is another feature of AIRSTEP. AIRSTEP's MIDI inputs can receive up to 8 specific MIDI messages, which are triggered when these specific messages are received. MIDI trigger can realize the same message output functionality as an AIRSTEP footswitch, and can output up to 8 different assignable MIDI, HID, and RELAY messages at a time. As an example, you can connect a traditional MIDI pedal to AIRSTEP and turn it into a wireless computer keyboard to send HID messages.




AIRSTEP Lite is a simplified version of AIRSTEP, with only wireless functionality. No USB and traditional MIDI interface, no RELAY interface, and no expression pedal interface. Other than that, all other functions and applications are exactly the same as AIRSTEP. AIRSTEP Lite is mainly suggested for wireless control, connecting a computer, tablet or a mobile phone to send Bluetooth MIDI and HID messages. When you only need to control a computer or a mobile phone, you can consider choosing AIRSTEP Lite.


But more importantly, Lite can not only be used independently but can also be used as an AIRSTEP’s wireless extension footswitches. It can wirelessly control all wired devices connected to AIRSTEP! So you can have both AIRSTEP and AIRSTEP Lite at the same time without worrying about the duplication of functions.
