I try to use DP 4.6 with MAS and Digidesign HD 2 Accel, with a 192 i/o interface. And the hardware does not appear in the hardware options. Everything works with DP and DAE. Or with the hardware I have and the audio prefs in the System Preferences. But not MAS and the hardware. I never heard it was impossible. Anyone has a clue?
Dual 1.8 G5 RevA, 2 GB RAM, 10.4.1, DP 4.6, Digidesign CoreAudio 6.9.2

You can only run any version of DP under "MAS only" or under "DAE only" modes, not both at the same time. It has always been one or the other. So if you want to run Protools hardware using DP as your interface...you will not have the ability to run anything MAS...

I know that is impossible! I don't want to run MAS and DAE at the same time. I just want to have the option to run DP, with MAS as the only audio system, and my Pro Tools HD hardware as an interface. A few plugins seems to work better as a MAS or AU version than as RTAS. I can do that with a Digi 002. But not with HD2 and 192 i/o. I don't know why. I can choose to process iTunes or Quicktime yhrough this interface, but not DP...

Hmm-I've gotten this to work before. It is supposed to work. I have protools HD1 system with the 192Digital interface.

Have you downloaded and installed Digidesign's "CoreAudio Driver"? It is available at their site if you click through support--> downloads. I think this may be necessary for MAS to see your hardware.

Also, you may try toggling from DAE to "MIDI Only" mode before switching to MAS. Then restart, then try going to MAS. My experience from trying this, which is probably with DP 4.5 or 4.4 and Protools Software 6.2 or 6.4, is that switching directly between DAE and MAS is buggy. I haven't investigated how to make this process flawless and I've had very little luck getting insightful help from Digidesign and Motu when it comes to the details of their stuff working together.

That said, post a little more about what's happening and I may have some more advice.

Hi MisterMarr,
I already had the newest CoreAudio driver, but I desinstalled and reinstalled evrything, then ran DP under MIDI only, trashed the MAS prefs. Rebooted. Now it's a little better: DP accepts MAS and sees the 192. It still can't use the ins and out in the real life, but it encouraging.
I go on, and let you know.
And thank you.

And it's better and better!!!
DP works and finds 8 channels or analog audio ins and outs.
It still can't find any ADAT or other digital channels, but it's quite usable.

Guy-
I can only access 8 of my 16 digital ins/outs with the 192-Digital interface in MAS, and I've been told by Digidesign and Motu that there's nothing that can be done about it. I've written them and asked them to fix it but they haven't said they would. I'm not sure if this applies to the full 192 interface, but I wouldn't be surprised if they tell you that 8 ins/outs is the limit when using the hardware in MAS with the coreaudio driver.

glad it's working for you.

I was also told by motu that you can only use the first 8 (analog) channels of the digi hd192. No access to the digital i/o.

The story as I was told is that it is a limitation of Digi's Core Audio Driver. Who knows.

If you have an HD system, you might as well run under DAE. You paid for that power, might as well use it. That is my plan as well. If you need to use a MAS plugin, or pitch automation, switch back to MAS, do the job, and then switch back. On my system, I can switch without so much as even having to close the song.

I have stayed in DAE mode also. The real drag for me is no rewire. I'd love to run reason alongside DP on certain projects.

4.5 was a big improvement in other areas, like quickpunch and plugin automation. It's too bad they can't bridge DAE and MAS...

so one can't use any native mas or au plugins when in dae mode? I was hoping to have the best of both worlds:(

No. When is DAE mode, you are using whatever plugins you have installed in Pro Tools instead. That's a tradeoff I am willing to make! Plus, CPU power for plugins is potentially way higher due to the presence of the TDM cards. If you have HD 2 or HD 3, it's a no brainer to run under DAE. DP runs many times faster and with many times more plugins under DAE with HD hardware. You get what you pay for....
