Hi!
Using jack a long time, now. I never activated "monitoring" on my RME
HDSP 9652 because I did not know how to make use of it. In qjackctl the
big block of additional 26 ports was always in the way…
Now, with pipewire, monitoring is activated by default. Surely, I can
deactivate it through some configuration I have to investigate further.
(Or a neat person here tells me how… :) ) But before I do this I want
to make sure not cancelling a handy feature I would have definitely
used if I was smart enough…
So: What are these "monitor" ports and what can I do with them?
And sorry for the newbie question although I'm not a newbie, at all…
Greets!

Generally speaking, this is a good explanation:

IMHO "Foldback" here is synonymous with "Monitor".

No, it isn't.
IIRC [1], a 'monitor port' in the Jack world is a readable
port that provides a copy of the signal(s) arriving at the
corresponding writeable port.
Suppose you want two (or more) apps to receive the same
signal(s), for example
A->X, B->X, C->X
A->Y, B->Y, C->Y
Without monitor ports, if the set A,B,C changes, you
have to modify the connections to both X and Y.
With monitor ports, you can do
A->X, B->X, C->X
XM->Y
where XM is the monitor port for X, and you need only
to change the connections to X.
The classical example is a recording or metering app
on your playback ports.
[1] Jack used to provide optional monitor ports until
they were removed some years ago (a bad idea IMHO).
It's difficult to find documentation on them these days.
Ciao,
