software around you.
AIRSTEP can control all devices with the MIDI interface. It can also control devices with a footswitch(TRS)
interface, like some pedals and amps without the MIDI interface.

and HID. Like effect software, Plugin, DAW, etc. It can even control the play/pause, backward and forward
of YouTube guitar lessons, page-turning of the music score, completely freeing your hands!
AIRSTEP has 5 footswitches, and can wirelessly expand 5 more footswitches by AIRSTEP Lite. It is capable
of sending up to 8 different messages per switch.
All functions can be easily set by the AIRSTEP APP. Programming and editing isn't your thing? Just load
any of the massive online presets with just one click, 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 are built to meet the most stringent environments faced by musicians.
