Well I had a play with qpwgraph and pipwire, and the some of the Ubuntu 
Studio audio tools with 23.04 (Lunar) on Gnome - and you can do stuff!

But I see what everyone means about pro-studios. It is all a bit clunky. 
and latency is a problem without an easy way to get in and fiddle with 
the settings. At least - one that I know of.

Apparently you can use some pipewire command line tools. But the manpage 
is light on information. I suppose your Ubuntu Studio Audio Config tool 
will help here - now I understand better what you were saying about the 
PIPEWIRE_QUANTUM variable.

With qpwgraph, I could make all of the connections that I used to make 
with The patch section of Carla. But everytime I clicked on another 
window, and then clicked back to qpwgraph, its window was un-maximised.

Hydrogen works.

I recorded an extra track into a previous Ardour project. Latency!

I recorded my electric guitar into an extra track via Guitarix. Same 
problem - naturally.

I played FluidSynth via the Virtual Keyboard without going into Ardour - 
there wasn't much point recording my virtual keyboard playing skills :-) 
No problems.

I didn't bother with any other effect/EQ plugins.

So. I didn't confirm what sample rate settings were being used. But if 
you can deal with the latency issue, you can do some rough/basic audio 
work on pipewire. For a true amateur like me - it would be OK after the 
latency is fixed.

Cheers,

Ross
