Not really. And I forgot to mention jackmix which looks like another
quick hack.
This is because it was not much of an experiment to start with but
rather an observation derived from finding a way to record the song
without so many xruns.
As such, the observation was quite clear: kernel real-time
capabilities, although they might play a role somewhere, had nothing
to do in producing xruns since switching applications resolved the
problem. From that observation then a question arose: there must be a
bad way and a good way of writing a Linux audio/jack application: what
is it ?

Indeed. That's the possibility I haven't explored since I think the
result of the observation was to see that there's a bad and good way of
writing such applications. Now, that the bad way lies with jackmix
and/or Qarecord is a second point that has more to do with technical
performance in the context of writing such an audio/jack application.
Which is not the case at the moment. I'm currently working on a project
that has nothing to do with such matters but I consider for a next
project to make a Linux jack application that would ease my music
making as I find there are some things that could make it easier to
make music.

Hmmm.. I'd disagree with this insofar as debugging these apps is
certainly not the matter.
Tschüß.
