This is great news! I am going to give it a shot as soon as I can, hopefully before the end of the year.
As for Jack in Pd, there are a couple of things. Pd by default uses Jack as an audio device, so it should be able to see those ports. But I don't think that is very controllable from within Pd. There are some objects that exist but aren't widely used that are for connecting Pd and jack channels in a more dynamic manner. Here are the sources: http://pure-data.cvs.sourceforge.net/pure-data/externals/jackx/ http://pure-data.cvs.sourceforge.net/pure-data/externals/k_jack~/ http://pure-data.cvs.sourceforge.net/pure-data/externals/tb/ jack_transport/ And thanks for the bug fixes for Pd. Pd could use a good security audit, especially since it is becoming more and more network aware. .hc On Dec 16, 2007, at 8:48 PM, Russell Bryant wrote: > Greetings, > > I have been working on Jack support in Asterisk this weekend and I > have it > working, as far as I can tell.
