Topic: Using 2 Firefaces 800 simoultaneously
I really need an help!
I need to use two soundcards at the same time, precisely two identical fireface 800.
They will be connected to the same computer (mac OsX 10.6.4), running Max/Msp 5 software.
I created an aggregate audio device, following these instructions:
Now I have two problems.
The first is how can I understand how to use the two soundcards input and output from max/msp.
Where can I tell to the Mac that the output from 1 to 8 are those of the first soundcard and
from 9 to 16 are the output of the second soundcard? Where can I set such information?
The second problem concerns the RME drivers. Indeed, when I connect both the two soundcards
to the computer I only see the driver settings and mixer corresponding to the first soundcard.
How can I see also the driver settings and mixer corresponding to the second soundcard? I need
to set in the mixer of the second soundcard a particular preset of outputs, while in the first
soundcard it is ok the default one.
Furthermore on the link http://support.apple.com/kb/HT3956 where it is explained how to create
an aggregate audio device, I noticed the following two points:
"6) If your audio devices all work with word clock, connect them together using a word clock cable. Connect the cable from the device you designated as Clock Source in step 5 to the input of each other device. Refer to your audio device product documentation for specific details.
7) If any of your devices do not work with word clock, enable the Resample checkbox for the devices that are not designated clock master."
I don?t know what "word clock" means. What do you suggest me to do concerning these issues?
Moreover, when creating the aggregate, I don?t understand why Mac sees on each soundcard 28 input and 28 output.
There should be only 8 input and 8 output on each soundcard right?
Finally, maybe this can help, I don?t know, I use a 800 to 400 firewire 9-6 pin cable from Mac to Fireface,
as you suggested me in this previous topic http://www.rme-audio.de/forum/viewtopic.php?id=5234
Thanks in advance
