Hi pd coomunity
I am looking for a way to build a multichannel playback array, the idea is to control the movement of sound in a array of speakers in a wall. there is a way to do it without a super soundcard with many many outputs? a way to implement in pd?
thanks
Hey Fernando,
I was thinking about posting something like this to the list today too! I'm interested in doing this too. I currently have a Sapphire Pro 24 external soundcard connected to my Macbook Pro, running OSX 10.6.
I haven't been able to get the Sapphire to output more than two channels through Pd (though it is supposed to be capable of 8).
I have tried making a multichannel patch, for eg [dac~ 1 2 3 4]. All that happens is I get a reduced signal from my 1 and 2 channels coming through my 3 and 4 channels.
So I'm wondering too
if there is an easy(ish) way to do mulitchannel?
If anyone is using a Sapphire with Pd and has come across similar issues
and
- Recommendations for multichannel output hardware that works well with Pd
(and preferable OSX)
thanks

don't know this card but have you set the number of output channels to 4?

you'll need as many independent channels as independent speakers in your array....

i second that. Pd is definitely made for multi- and manychannel setups. (the first publicly shown project i did in Pd was 1999, when we used 16 channels; in the meantime, we regularily use Pd with 64 channels output; this is of course with some "super soundcard", but it's just to tell you, that Pd can and will do it's part of the multichannel setup; for information on whether your OS and soundcard are up to it, please refer to the manuals :-)

this sound mainly like an internal mixer setting of your soundcard.

"...playing at the same time".
e.g. you could do a 70 speaker installation with just a stereo output and a lot of routing logic, e.g. use relays to properly dispatch the audio signals to 2-of-70 speakers; obviously you won't be able to do WFS with a system like that, but you can make a sound wander around between speakers. bear in mind, that relays also have a nice aesthetics on their own...the computer we used for driving such an installation was named "Klapotetz" [1]

whats the hardware for this?

64 channels.... I am drooling with the possibilities.
