Hi
I have several questions about possible audio latency settings for a unique combination of devices being drivin by windows xp pro.
brief hardware info:

Soyo Dragon KT400 Ultra "black edition"
Amd 2500+ Barton core 333
512 megs corsair PC2700 DDR
seagate 80 gig 7200rpm ata 100
Ati 7000 radeon 64 meg dual head
No Modem (system not used online)
CMI8738 onboard audio
M-Audio radium61 usb keyboard/device controller This One
Roland Digital recorder This One
Alesis Amplified Monitor/speakers Here

Software:
Windows XP Pro SP1 w/all patches
Stienberg Cubase SX

OK Now The Fun Part,, Questions we cant find answers for on any of the recording forums,Nor in the manuals for these devices.
Sync up of all the devices went ok,They all see and control each other, BUT
Latency is terrible.
We Hit a note on the keyboard,to playback live, or record,And theres a huge delay before the actual note deploys.
We saw this setup in a trade demo, And latency was only .3ms,
BUT ours is running at about 1 Full second+.
We were told by a rep, that its a windows setting, But,We are unable to locate any actual information about these settings,Or possible registry edit/settings that apply.
All of these componets are SUPPOSED to be Compatable with XP Pro,And its a very popular recording software,BUT,Actual settings and Good hints are very hard to locate.
Any info leading to the whereabouts of latency adjustments will be applauded~!!
Thanks
