What is the Xio™?The Xio is all you need with or without a computer to record, synthesize, MIDI controland process effects for performing or studio use. In one mode, it’s a standalone synththat works separately from the computer if desired (powering from batteries or anexternal power supply) or powers over USB when connected, and in another mode it’sa MIDI controller, where its knobs, buttons, Xpression pad and stick can all be used totweak software or additional hardware parameters. Furthermore, you can now utilisethe onboard synth whilst MIDI controlling.In both modes, the keyboard also functions as a 2 In/2 Out USB audio interface,for streaming audio from the computer directly to connected speakers or an amp,or for recording a microphone or line signal plugged into the rear panel. Alternatively,in standalone mode without a computer, the keyboard also works as a miniature mixer,for amplifying and blending a mic and line signal for recording or playback.Getting Connected and Powering UpIf working with a computer then the Xio will power over USB, so the only actionto take is to connect the keyboard to the computer using the supplied cable. However,batteries may want to be inserted if carrying out a mobile session or trying to conservelaptop power. If this is the case, insert 6 AA-size batteries after removing the panel onthe rear of the keyboard.An external power supply is also supplied, for an alternativemeans of powering the keyboard if not connected over USB.If using the keyboard in standalone mode, batteries or theexternal PSU can be used as a source of power.When the unit is connected and plugged in, the switch onthe rear of the keyboard should be set into the appropriateposition, as follows: Xio powering up optionsFA0089-02
