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 :-) > >> I have tried making a multichannel patch, for eg [dac~ 1 2 3 4].

"...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] ghmsdft IOhannes [1] http://en.wikipedia.org/wiki/Klopotec -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5V+vEACgkQkX2Xpv6ydvQazgCdG4Y1bFjEqaQeGvtasQD6Fcfo 8SAAn0Gj5KIfawM5WgRiZLIfj4FBoGgQ =saf5 -----END PGP SIGNATURE-----
