X Air Axis is an iOS App for iPhone and iPad which allows surround-sound control using the Behringer X Air series of consoles. Control of up to 8 speakers (for xyz control) is permitted, with 3D control of eight channels of audio. Several 'mind-blowing' trajectories are incorporated into the App, allowing for stunning spatial effects in a true 3D sound space. Remaining non-3D channels can be routed to the 'normal' L-R sound system for more routine PA applications.
