AIRSTEP Lite is the simplified version of AIRSTEP, it has removed all hardware control interfaces and only kept the Bluetooth to send MIDI and HID messages. This means that Lite can only connect to mobile phones, tablets, and computers to control software, but cannot control hardware devices. In addition to this, the other functions of Lite are the same as AIRSTEP. And, can be re-programmed (Lite Advanced firmware) to function as an Airstep Play: Foot control the playback, loop, speed and pitch of video & audio on iOS, Android, Mac and PC.
