I am posting this in JV to again remind all users of digital consoles how important a good uninterruptable power supply is for your digital devices. EVERY software related glitch or gremlin I have ever had with any digital device has been caused by a power spike or brownout. Since I began using a UPS many years ago I have never had any software or operating system related problems since. I even use one at FOH on my analog systems to send stable power to my digital effects and processing. Never a single problem in the last 10 years related to power. It is a cheap insurance policy. You don't need a very powerful unit, just enough to keep the voltage fluctuations from reaching your gear.
