I just wanted to gush a bit about this amazing tool for pipewire ive come across. Its in the repos if you wish to use it
This patchbay is so far in my experience better than Helvum in every way. You can easy setup pipewire graphs for different effects, routing,etc. with ease and save them to a file for applying easily later.
All the pipewire nodes are easily identifiable with proper naming, labeled as alsa,pulse, or pipewire nodes, along with identifying the used ports and the human readable interface/node name used in the settings.
Unless you have a specific need this patchbay doesnt cover i would absolutely say this should be the go to patchbay for pipewire folks looking for a good and easy to use patchbay.
