how do i use multiple channels out of pd -- i am planning to use 2 or 3 soundcards and wanted to know if it is possible to use the different dsps out of pd ... (linux) any other ideas of using multichannel?
thankyou

Hi,
Sorry, this is not exactly an answer to your question: in fact it's another related question.
I seem to remember there is some experience among members of this list of the RME soundcards under Linux, and using them with PD.
Has anyone successfully achieved multichannel i/o using an RME card and PD (Linux)? It seems to me one of the RME cards is probably the best way to go, in terms of h/ware spec and driver support, but if anyone has other ideas....
At the University of Glasgow here we are interested in setting up a Pd box to do some sound spatialisation stuff. If anyone has any info or experience in this area, I'd be interested to share ideas/problems as we'd really like to get this going quickly.
cheers,
Nick
i have never tried RME or other multichannel cards with pd but i used 4 sb-128pci soundcards for a cheap 8-channel (dac~ 1 , dac~ 2 ... dac~ 8) solution in an exhibition(different interviews[mono-soundfiles] triggered by external midi events). this solution worked fine, but i didn't (have to) care for sync. DIETER
that was exactly what was on my mind but i wanted the outputs to be synchronized...
what about using one midi input that triggers each one of the dsps -- this would also give some hardware latency between the cards?
i suppose you were using OSS for this setup?
thanks

Hi all, and sorry not to have offered something earlier about this...
If you have several soundcards (at least under OSS0 Pd will willingly open them; each 2 channels you ask for on either input or output will cause Pd to try to open another "device". HOWEVER, if you don't have some way to sync the cards together you'll have occasional clicks in the input and output as Pd re-syncs them. Most soundcards aren't syncable; however, you might be able to get somewhere with a soldering iron.
The RME cards do work with Pd; I've had very good results from mine. I've only used 8 channels so far but theoretically you can go to 26, both in and out. You have to use a special driver by Winfried Ritsch; the Pd web page contains my re-packaging of this. As far as I know the RME is the ONLY tested multichannel solution for Pd.
