Hi,
I just discovered, that the Portaudio team is working on a Jack backend for its library. A preliminary version seems to be in the devel branch on portaudio-CVS.
As Pd already uses PA for its OS-X and ASIO support, it seems only natural to me, if Pd could use PA for Jack on Linux as well. This would remove the need to have different Jack patches around.
So, did anyone here try Pd with Portaudio-Jack already?
ciao
Would it be possible to have Jack In and Out objects in PD? This is maybe not possible with Portaudio Jack and I don't know if it's possible at all, but it would enable other applications to send or receive audio to/from PD.
sorry,i sent the previous mail to pd-list insetad of -dev

my expirience when fiddling around with pd(-jack-fifo)+jack+ardour, was that the dac~s of pd appeared as pd-outputs in ardour. i didn't try it the other way (ardour->pd) but i think the signal would just appear at the adc~. of course it would be nice to have named inputs or at least a possibility to dump the mapping of jack-names to adc~/dac~

Normally I do this with qjackconnect, where you can just "patch" the outputs and inputs of the jack enabled applications together.

"jack_lsp" lists the available jack-ports, "jack_connect" and "jack_disconnect" (dis)connect these. I only used the fifo-pd-patch yet, and with this the PD-ports are connected to the alsa_pcm:in_? and alsa_pcm:out_? automatically.
As I couldn't get alsaplayer-jack to work, Pd now also is my preferred mp3 and ogg player, when running jackd :)
ciao,

but it would be much more flexible, if you could have several jack-in and jack-out objects.

We have been discussing this at the ICMC with Miller, and he said that this would be a great solution (the new portaudio supports almost everything that exists).
There are changes to PD necessary though, because there are changes in the portaudio API.
I think it is better to wait until Portaudio V19 is officially released.
