hey
i programmed 4 different sounds in puredata. now i want them to play on 4 different speakers simultaneously, meaning each speaker is supposed to play a different sound.
is it right that i just add a number to the "dac" object to split the sound in different channels? right now i have "dac" four times, so do i just put "dac1", "dac2", "dac3", "dac4"?
and then, apart from that problem, i don't know how to connect the speakers. i have a macbook. what do i need to connect the 4 speakers to it playing 4 different sounds?
thanks for any help!

4 audio channels

Well that's my way to output 4 channels (in attachment)
But you've got a macbook right? I don't thik you can do this with it's defauld soundcard as it has only 2 channels! You have to get a multichannel soundcard.
Then , the connections will be ok if you change the Preferences>Audio Settings and it depends how your soundcard works with routing the outputs.I still wait my new Terratec x24 to arrive , from day to day
and test it with my MacbookPro in such projects. -
the macbook has optical out.. so you need one of these:

and then a surround system that accepts optical input.THIS article might be helpful
http://creativemac.digitalmedianet.com/articles/viewarticle.jsp?id=56671past that.. have a look at the [dac~] help file. you can make an object that has 4 inputs [dac~ 1 2 3 4] to which you can connect all 4 sources.
I don't know how complex it will be to make sure all four of them get to the right spots.. but there are hints in the dac~ help file about setting up multiple audio channels. I don't have the set-up to test it.
good luck

You don't necessarily need to go the optical out route. You could get an audio interface that has at least four outputs that connects via USB or, depending on which MacBook you have, Firewire. It doesn't specifically have to be surround, just multiple outs. M-Audio has some affordable ones that aren't bad for the price.
