@wtay Is there any way to put MIDI ports on separate nodes? I currently have a single big block with Midi Through & friends.

I don't think so.. I'll check it out..

Does anyone know if pipewire supports jack_session? This is now marked as deprecated, yet I know of several people who use it precisely because it is very simple and lightweight. It's not supported. if I am not mistaken, jack_session is a prerogative of jack clients that adopt and support it. altho...

Well none of that sounds too great. I'm wondering if it's even worth it to try to switch to FFADO. What is the advantage exactly over just sticking with Alsa? I haven't done a whole lot yet with Ardour, but so far I haven't run into any problems. Also, I think if I downgrade my Audiofire firmware t...

It's not supported.

...just for my understanding: pw sets latency on a client base? If a client asks 64 sample buffers and another 1024, the graph is using 64 sample buffers and the one asking for 1024 gets woken up every 64 samples as well. If it can't produce 64 samples, it can do its own buffering (like what the AL...

...just for my understanding: pw sets latency on a client base? The PipeWire buffer size in the graph is the same for all clients. Client can each make a suggestion about their preferred latency and PipeWire will configure the minimum latency of those suggestions. PipeWire does not attempt to have ...

@matyas That's just a case of old documentation still floating around. Install QPWGraph instead of Qjackctl. Problem solved. Ardour works great with PW-Jack. qpwgraph doesn't handle all the usecases that qjackctl does: it only provides the patchbay bits. I don't think there is a widely-accepted PW ...

Just one question at this stage of pipewire development, and in particular, for midi playback and recording. Is it sample accurate, like JACK? I see that wtay has said yes. I don't know if sample accurate makes a whole lot of sense for MIDI. At 120bpm, yes, every beat lines up with a sample. There ...

How about netjack?

netjack2 is fully supported with opus codec and all. netjack1 is not supported.

How fully does pipewire support software that normally talks direct to both audio and MIDI ALSA?

There is a dbus audio device reservation protocol that should be used (jack and ardour use it). PipeWire (actually wireplumber) will release the audio device when those apps request it to.

Yes.

If Pipewire allows us to connect alsa-midi ports with jack-midi ports on the fly without first creating jack equivalents of all alsa ports, that would be a definite improvement. All of the ALSA midi ports automatically become PipeWire/JACK midi ports and you are supposed to connect them at the Pipe...

<PulseAudio> didn't work out so well. On the contrary, it has been extremely successful in terms of adoption. Even music production apps have implemented PulseAudio support (which I think is utterly pointless). It's almost ubiquitous at this point. It's just that PulseAudio wasn't meant to be a gst...

I think the million dollar question is: Why does Pipewire attempt to replace JACK at all? It didn't need to do that. And I don't know of any jack users who were even wanting that. Sure, people wanted an easier way to configure jack, but no one was saying "replace it with something else which p...
