The Virus TI is an analog synthesizer released in 2005 by the German manufacturer Access. The synthesizer includes a number of settings that can be defined by the user. This can be an extremely useful feature, but sometimes you might want to return the Virus TI to the state it arrived in when you first bought it. Resetting the Virus TI to factory defaults is a simple process, merely requiring you to press the right buttons in sequence.
Turn off your Virus TI and unplug it.
Press the button labeled "Arp Edit," found just beneath the Master Volume knob.
Plug the Virus TI back in, while still depressing the Arp Edit button.
Wait until the Logo and BPM LED lights begin flashing alternately. Release the Arp Edit button and turn on the Virus TI.
