[Openal] Question about Motu 828mkIII hardware

[Serge Lages]

Hi Dan and Jason,

Thanks for your replies. I am a real newbie about sound development so
please excuse me if my questions are a little dumb... :/

If I understand it well, having a single 12.2 system managed with 2 cards
will be difficult (but possible).
And what about having a single application managing two 6.1 systems ? Or
even two applications, one for each card, then I can make them communicate
to know where to play the sounds.

Let's say I put 6 speakers on the left of my room (managed with my first
card) and 6 on the right (managed by the other one), if my sound is well
spacialized and that each speakers know its position, if my sound move from
the left to the right, in theory it will not make any difference with a real
12.2 system ? Or am I completely missing something ?

Best regards,
