aggregate devices in OS X

aggregate devices in OS X

a friend is working on an installation project created in Max/MSP
where she wants to derive 12 channels of audio output from two
separate firewire audio devices

the devices are:
M-Audio Firewire Audiophile
M-Audio Firewire 410

she has physically daisy-chained these two devices together then
created an aggregate device in the audio/midi setup

but apparently this hosed one of her drivers and still had no luck
getting the aggregate device to work after re-installing the drivers
for both M-Audio I/O’s

any tips on how to set up an aggregate device using two M-Audio
firewire audio I/O’s in Max/MSP?

we’ve searched the list and found some info but it didn’t really help

thanks in advance,
KIM

I done this, with different hardware, and it worked great.

Maybe don’t daisy chain them?

Hey Kim,
Is she only interested in the Audio Out channels?
While not acquainted with the M-Audio models, we managed to extend an 8
channel Metric Halo with additional ADAT channels. IMAC/4.6/OSX.
Worked like a charm – got 16 speakers for the price of 8 and a bit…

M-Audio probably is hosed by Digidesign. Its the only interface family I
know which requires a driver, and the installer even requires a restart
after installing for such a basic thing. I bet using more than one
interface on a single machine is far beyond the imaginable for Digi
developers…

If they would do it like all others, they would not have to deal with
bugs, mostly design bugs (like using the interface as copy protection…)

Did you consider to make an agregate device with the internal sound of
the Mac? Might need additional converters for the spdif outputs to get
12 channels…
