It seems to want to cause a lot of gliching noises, some dropping out, and sometimes a little stop and start studdering action. Quite a bit more than I had with my motu. I have a new chip fire wire card with a texas instrument chip set, and on the FW control pannel, my latency is set to 50 percent. Anything else and it really gets funny. I've tried the buffers at, 256 and 512, and that doesn't seem to make a difference. Anything else I might try before doing a clean install of windows XP? Most of the time it'll play through a song, not hang up, but still make a few of those poping or glitching sounds. Then again when I use even a couple big sounds from dimension, it wants to bog down. Once I freeze the synth it's better at least in the bogging down department but we still get the noisey behavior. Took a lot more than that to make the MOTU go fuzzy. I know aew of you are using this board with no trouble, and if a re install is what I need to do, that's what will happen, but if there's anything I might try first, I'd like to hear about it. Thanks for any thoughts. http://www.gbrayton.com http://www.myspace.com/gbrayton http://www.sonicbids.com/GregBrayton
