I dont know if you are refering to me, but to answer your question in case you are. I am a professional sound engineer, and Im getting into recording in a digital system. So I got me a nice little interface, and a few other stuff. Will be working my way up to a Motu 896HD, Avalon VT747, Neve 1272, and a Digimax FS with other little stuff. Anyways, thats besides the point; I would like to inform everybody reading this thread, THE EDIROL IS A GOOD SOUNDCARD, and today I ran by Pro Sound and I pick up a Monster Power Pro 800 surge protector/power cleaner.....AND IT DOES MAGIC, not the kind where ferries come out of nowhere, but I mean it fixed my interface problem. I cam home at 6PM and its 1:40 AM, and no problems still. The greater test was that I set my buffer size to 256 WHICH IS UN-FRIKEN-BELIEVABLE. That was impossible for me before, even when the thing wasnt throwing a fit. I figured it prolly was some programs trying to fight for priority, but since i plugged this Monster in, no problems at all...actually I noticed my DS-7's sounded allot fuller and cleaner, and my sub had WAYYY nicer low end. My PC is a bit more stable, although I never really had any problems with it since I built it, and so im happy with it. If ur interested in what Im running, I posted an earlier thread with my system specs on the first page. So, in conclusion, I want to save anybody having the same problem as I did, to go out a buy a good Monster surge protector, dont go cheap, invest to take full advantage of your gear.
BTW, defragging helps, I knew that a while ago. Im not running immense amounts of VST's I monitor my CPU performance. What I noticed is that my CPU was spiking from 50% to 100% and then back again in about 200 Ms time, then my interface would crackle and pop and reset. AND!!! DO NOT, UNDER ANY CIRCUMSTANCES PUT YOUR PROJECT FILES ON 2 DIFF HDDS, GAVE ME BIG PROBLEMS WITH CUBASE SX3. Run all ur studio stuff on a secondary HDD. Anyays, just some basics you should stick to, and i had to learn the hard way. Its maily a bad Firewire chipset that will give you problems, un-maintained PC (or too low of a performance) and definately or, the absence of a good surge protector and power cleaner or conditioner.
