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.
