Pro Tools Aggregate I/O

[GTBannah]

Hello, folk,

I have the DIGI 002 connected and, in the play back engine menu, I have four options:- DIGI 0002, built in output, built in input and Pro Tools Aggregate I/O.

I understand all but number four. There seems to be no operational difference between number one and number four.

Any ideas?

your "fourth" option refers to PT9's ability to allow the user to set up an aggregate device (made up of any the available core audio devices you choose.) Your digi rack cannot be used in the aggregate device set up, so unless you have a 3rd party core audio interface, you pt aggregate I/O would be made up of any of the built in mac I/O.

Sorry, you lost me there...sounds like this allows me to set up a group out somehow and output to multiple places at once with the aggregate I/O. How far off am I?

Thanks

.... but using third party CoreAudio interfaces, you're saying ....

Interesting! DIGI-AVID is opening the options up!

Not just a group out, but allows you to combine interfaces up to the allotted 32 I/O. This is an OSX feature that PT9 takes advantage of.

As mentioned before, it is not supported with the 002/003 family, or any HD hardware.

My problem is that my prior 003 I/O settings have defaulted to the Aggregate I/O and I can't seem to change them back. I hit default but it doesn't give me active 003 I/O (ie 4 x stereo analoge INs, etc).

Ant suggestions?

Try the first group of instructions in Kbase 381131 and choose the 003 as your playback engine.

So does this mean with PT9 HD that connecting 3rd party FireWire/USB interfaces won't work?

Not what it means.

It's not the software, it's the hardware. if you are using TDM hardware, (i.e. core cards) you cannot aggregate it with another device (i.e. USB device). However, there is no reason you could not use the HD software with other hardware. You could aggregate multiple devices and use them with the HD software... you just can't use TDM devices.

Hey guys I'm new to this forum and couldn't find the way to start a new thread cause I dont know if people still reads this one, I'm having trouble creating an agregate device on my mac, I have an M-audio Fast track pro and a yamaha mg-166cxUSB mixer, and I would like to get the ins from the mixer and from the ftp all at once, but it doesnt seem to work, I cant even create an agregate with the inputs and the outputs of the mg166.
I'm able to create the aggegate with the mixer and the ftp, then I go to playback engine into pro tools 10 and select this aggregate device, but I heard I have to do something in the I/O section and I couldn'f figure out whats that, I just clicked default on both the ins and the outputs but it doesn't work.. does anybody know whats the problem here? thank you!
