Using MOTU 828 ASIO drivers with Vegas 6

How do I get Vegas to use the ASIO drivers with my MOTU 828 hardware instead of the WDM drivers? Windows XP Pro running on a Dell Latitude D800 laptop.

I'm having playback stutter problems while using Acoustic Mirror and changing the MOTU Samples Per Buffer or "Enalbe full Wave support for legacy (MME) software (less efficient) seems to have no effect on the problem. Task Manager shows only 25% to 40% processor utilization. If I use Microsoft Sound Mapper to run the 828, the stutter goes away, but that obviously brings me back to only two inputs or outputs.

Hoping the ASIO drivers may be more efficient.

Tools | Preferences | Audio Device | Audio Device Type | MOTU ASIO (or whatever is is).

Not seeing an ASIO driver listed. Hears what I show:

Microsoft Sound Mapper
Direct Sound Surround Mapper
Windows Classic Wave Driver
MOTU FireWire Audio

Playing around some more shows that I can use the Windows Classic Wave Driver without problem and get access to all my MOTO inputs and outputs, but I was wanting to try an ASIO driver to see if that would increase my plug-in or track counts.

Acoustic Mirror is extremely processor intensive. Even if your task manager only shows 40%, this could still be a problem if you have several tracks running. If you haven't done so already, mute AC and see if this effects the stuttering. Also try soloing one specifc track with AC to see if this has any effect. Personally I never even bother with AC in Vegas and only use it in Sound Forge. I know that my comments don't speak to your driver question, but they are something to consider if you haven't done so.

"MOTU FireWire Audio" is what MOTU calls their ASIO drivers.

Select this entry and you will be using the ASIO drivers.

drbam,

Muting Acoustic Mirror does stop the stuttering. I run the final tracks through Sound Forge to do the final fade in's and fade-out's. I guess I could do the AC there and not have it while I'm doing the initial editing. Shuck's; thought I could have it all :)

Okay, that's what I was afraid of. Thought the ASIO drivers were suppose to be more processor efficient than the WDM drivers, but I guess at least in the case of MOTU with the 828, they aren't :( I guess I'll just have to run Accoustic Mirror in the final stage within Sound Forge.

I've tried for a year now to get Vegas to recognize the ASIO driver for my 828mkII. It does, for audio playback and recording, but will not recognize the time code functions of the MOTU box. Sony says 'that's just the way it is". sad. It's actually an ASIO2 driver that the MOTU wants to see.

We don't support the external sync/timecode mode of ASIO.

>>It's actually an ASIO2 driver that the MOTU wants to see.

I don't know what you mean by this.

We support ASIO2. Specifcally the more efficient streaming mechanisms provided by ASIO 2.

We don't support Direct Monitoring or external hardware time code sync.

It's a shame that Vegas doesn't support the Time Code functions of external hardware devices. It woul make Vegas, which already a very good tool...even better.

Someday, the cool thing would be: have Vegas use BWAVE files to record with (instead of WAV files), thereby being time stamped with incoming time code (i.e. the timeline time) . Would make Vegas a great tool for doing ADR sessions.
