Also make sure you:
• Switch off Bluetooth.
• Disable any Anti-Virus software.
• Switch off wireless network and unplug any wired network connections.
• Switch off screen saver and set sleep mode to 'never'.
• Make sure your hard drive doesn't have a sleep mode selected.
• Ensure you have ample room left on your hard drive (this is approximately a minimum of 10% of your hard drive capacity - both internal and external).
• Close down any other software, including antivirus software or the like.
• Calibrate your USB buffer setting. Start with the USB buffer slider at the hard right position, and slowly move it as far to the left as you can before you notice any audio interruptions or loss of performance. Ideally you will want the lowest buffer setting possible.
