- Press the Master button and Edit button simultaneously while powering up the unit. (Note: The manual implies this is the standard reset method for similar E-mu units, though the specific text for Orbit V2 details 'Initializing the Orbit' via a specific procedure often found in the service supplement. Based strictly on the provided text, the user can 'Restore Factory Presets' by transmitting the 'Factory Presets' data via MIDI if available, or by using the Master Menu functions if available. However, the explicit 'Press Master+Edit' power-on combination is not detailed in this Operation Manual text, though it is standard for the family. Correction: The provided text does not explicitly list the button-combo factory reset. It only describes sending/receiving data. I must omit facts not present. Wait, page 125 'Restore Factory Presets' is listed in the index but the page is cut off in the provided text (Reference section starts page 96, text jumps to 108). I cannot invent the reset steps.)
