Troubles recording 24-bus w/3 MOTU 2408mkIIs

I am attempting to enable 24-bus playback/capture within Vegas Video 3.0b via 3 MOTU 2408 mkII interfaces. All 3 2408s are stacked on 1 MOTU PCI324 card. The problem I am running into is that the last 3 stereo busses on the 3rd 2408 are not showing up within Vegas Video 3.0b. For example, I see the following selections when I attempt to assign a bus to a particular routing option (namely 2408mkII channels):

Master
SoundMAX Digital Audio
PCI-324 2408-1:Analog-A 1-2
PCI-324 2408-1:Analog-A 3-4
PCI-324 2408-1:Analog-A 5-6
PCI-324 2408-1:Analog-A 7-8
PCI-324 2408-2:Analog-A 1-2
PCI-324 2408-2:Analog-A 3-4
PCI-324 2408-2:Analog-A 5-6
PCI-324 2408-2:Analog-A 7-8
PCI-324 2408-3:Analog-A 1-2

However, the following selections, which should be appearing, are not:

PCI-324 2408-3:Analog-A 3-4
PCI-324 2408-3:Analog-A 5-6
PCI-324 2408-3:Analog-A 7-8

Note that, within the MOTU Audio PCI-324 Console, I have implemented the following settings:

Sample Rate: 48000
Clock Source: PCI-324: Internal
Buffer Size: 1024
Monitor Outputs: 2408-3:Analog-A 7-8

Both 'Enable Routing' and 'Mono Routing' are checked. And all 3 interfaces have 'Analog' selected for Bank A with all inputs enabled and all Output Sources set to 'From Computer'. If anyone could shed some light on how I can get the missing three Input/Outputs (2408-3:Analog-A 3 through 8) to show up in the Vegas Video 3.0b routing selection lists, I would greatly appreciate it. Please reply to this message if you can help!!!

George, any suggestions on where to start? What type of Windows problem do you think would be causing the issue? Let me know if you can.

Thanks for the input....

Hi LTrain,

I'll bet you're using Windows 2000. I believe SoFo answered in previous topics (somewhere), if I remember correctly, that Windows 2000 has a documented limitation -- namely, that it can only expose 10 digital audio channels at once. (Thus, your SoundMAX and then 9 MOTU stereo channels.) I think this was upped in Windows XP to some huge number. You might want to consider upgrading to Windows XP. If you are using this at work or somewhere you need Windows NT Domain functionality, you may need Windows XP Professional. If not, say a home studio, XP Home will work fine for you and is in no way crippled, it simply doesn't have some of the functions included that are more pertinent to business and enterprise locations. Good luck.

Stickstr, thanks for the valuable input. I am running Windows 2000 Pro. I guess I'll have to try switching OS's. At least it's not a hardware problem with the 3rd MOTU. Either way, thanks for the help................

This is correct. Windows 2000 has a hard limit of 10 audio "ports" through WDM base audio drivers. WinXP improves this, but to only 32. There is no work around in either case.
