getting started with qJackCtl on macos

hi,

you rather use "Connections" (or "Graph") to explore around... the "Pathbay" is mainly to keep active persistent connections...
you can also read this to get acquainted with the distinct functions of either ;)

hth.
cheers

you have to have those apps up and running though, to have them show up in the patchbay sockets and plugs listings... right?

IDK :(

Let me tell ya that I have zero knowledge on how this all is supposed to behave on macosx and coreaudio, because i just don't care.
But anyway, qjackctl is a UI interface to JACK, and JACK as an infrastructure only deals with JACK-aware devices and applications, period.
That said, I'm afraid I just can't help you on whether macosx/coreaudio have this or that facility for you to share or "mux" some sound, in and out, to and from the JACK sub-system--maybe there's something, maybe not, I really don't know, sorry. Perhaps, you'll need to go into another forum, one that is dedicated to the bitten-fruit corp. at least :)

Is Jamulus configured to run as JACK client application? if yes, then it should appear on the qjackctl Connections and/or Graph windows, showing that it have a couple of input ports and, on the other side, another couple of output ports. It's is at this point that you shall connect each one of the Jamulus input ports to system/capture_N, and its output-ports to system/playback_N, respectively. Only after that you can play, hear and be heard, through the sound device you are using for JACK, a Focusrite Scarlett Solo USB, right? And only after that you can go to the qjackctl Patchbay and setup a persistent connections profile, as to save you all the trouble to re-connect all this stuff again tomorrow or after... but remember, you'll always need to start JACK and launch Jamulus on your own: the Patchbay only makes the intended connections, it doesn't run ther apps for you, ever.

hth.
cheers

Yes, video is rather old, but the same methods of linking different programs, ins and outs apply.
Some versions of osx have issues with jack, here it is mentioned and a version that does work
is linked, https://ccrma.stanford.edu/software/jacktrip/osx/index.html
jackctl is whats used in Linux, the name is unimportant, and it was not me who said I did not care.
It is a relatively easy program to use, the video I linked shows the way around it.
First you tell osx to use it as the sound device instead of core audio.
And in the jackctl settings, you can tell it to use 15 chanells, or more if they are available,
these channels can then be used by the programs, so each program uses a different one or two
and not conflict with another program.
Then in every program you want to use with jackctl you find the settings in the program and tell it to use
jackctl.

Most audio programs work with stereo, so channel 1 will be left and 2 will be right on the master,
if you input only on channel 1 you might see only one side of the DAW master meter light up, if so and
you want stereo input the same source to chanel 2, that should solve that problem.
Its just a matter of playing around and building up on how it comes together.

Looking at the image in your first post, it doesn't seem jack is installed, though am not familiar with mac,
the images in the link I posted in this replay are very different.
You also need to install jack first, then whatever jackCtl you are advised to use.

yes, I don't care a bit to macosx, nor even close to anything that comes from cupertino, sorry again.

but that doesn't mean I don't care about you or your problem. even though it seems deeply related to the idiosyncrasies of the platform, which is NOT GNU/Linux (the only one in careful support here:)).

now, about two other things which I think you misunderstand about JACK and qjackctl:
1. QjackCtl does not come with JACK bundled, although the opposite is often true, especially on non GNU/Linux platforms;
2. As far as I know of Jamulus architecture: a standalone Jamulus server only deals with network exchange--it is entirely useless for you to install JACK on the server, or even run it there, no matter if you use QjackCtl or else to start and interfere with it.

as @Musicalme said, you have to install JACK (jackd) on the very machine that you have your physical sound device plugged in--this is your macbook and the focusrite usb for sure--you have to install, setup and start JACK over that very sound device exactly, possibly under the "coreaudio" driver, and you can use QjackCtl for just that (or you can start jackd from the command line, giving it the right arguments, your choice). And finally, when JACK (jackd) is all set up and running, you launch the Jamulus client and connect its JACK ports to the system:capture_N (mic, guitar, etc.) and system:playback_N ports (speakers). You may use QjackCtl Connections or Graph to do the connections (but not the Patchbay yet) or you can go full command line with jack_connect et al.

hyu.
