Hi Sjaak, I'm using a PC and running xp sp3. The local store loaned me an 896 HD and I also tried out the ultralight and would get this occasional dropout proceeded by a micro second high frequency squeal and pop. I've tried every firewire card I could get my hands on, made sure that they had the Texas Instruments chipset, not running anything else on the computer, optimized the operating system. I've spent hours talking with the store technicians and on the phone with Motu and tried every solution they could think of except changing over to a mac. This has all been with an Intel motherboard, Intel duo core cpu and 4 gig ram. I have a focusrite saphire pro 26I/O that works with it no issues, but was wanting to run a second computer to process midi synth sounds into my present setup. I am also hoping to use this to interface my Yamaha O3D via Adat into the computer. Paul At 04:40 AM 6/17/2009, you wrote: > > Hi, > > I've been looking for a half rack size interface.
