I see. Well, imho this can cause unneeded problems.
For example, this student of mine didn't yet setup jack.conf, etc.. to get
real time priority, and therefore Pd kept complaining.
It's good that Pd complains, but we had to find out by ourselves that was
because it started with rt automatically.
And yes, it can be easy as launching Pd from the terminal, but I believe
most of Pd userbase starts Pd with a launcher.

Besides, rt without rt kernel is working better, but I don't think it's
stable enough.
And this could also be the cause of bad performance.

If ppl really wants this feature, at least Pd should clearly state at the
startup, in the console "look! I'm about to ask for real time priorities,
if you don't want it <do something>..."

Oh I see, I thought Cyrille was still on Nusmuk.

mm, shame I didn't check that yesterday, that machine is gone now.
Anyway, the Xth Sense is already out there.
It's not ready for the public,
but you're welcome to download and try out what about this issue. It would
be appreciated! :)

Just download the Xth Sense lib, rename the unzipped folder to xthsense,
put it in pd-externals, download the XS software and launch it.
At the bottom left of the bigger window there's the Analysis module with
graph and the slider I'm talking about.
you need an audio input, or just place an [osc~] somewhere there.
