This sounds highly unlikely. Maybe your "delay" setting is too low? Or
Pd is not actually running with realtime priority?
I also bump the sound-generation process up to realtime priority.
Pd itself already tries to raise the thread priority; if
For what it's worth, I actually get fewer xruns in callback mode, but I am
running computation-heavy externals for much of my sound design so YMMV. I
also bump the sound-generation process up to realtime priority.

Ah, I thought you were talking about the "polling mode vs callback mode"
thing. Yes, the API docs should mention in which context a function may
or may not be called.
For example, functions that can be safely called in perform routines may
be annotated with something like "\qualifier
Well, I don't mean documentation all internal mechanisms but, in this case, it
might have been helpful to at least note *which* functions should or shouldn't
be called in which situations. For instance, I note which libpd functions *not*
call when DSP is running.

Yeah, all API functions in "m_pd.h" should really have minimal
documentation (preferrably doxygen).
However, I'm not sure that "m_pd.h" is the place for documenting the
inner workings of Pd... I think the official manual would be a more
natural place,
Joseph: Do not be embarrassed. Understanding the engine is relatively opaque
IMO and info is scattered in different places.
Christof: IMO these kinds of important details should really by in m_pd.h. The
API is pretty stable at this point, so it would pay to fill out the header.
This was my
Glad that I could help! Very little of this is really documented
(accurately). Personally, I figured this out by reading the source code.
Ideally, we should improve the official documentation in
http://msp.ucsd.edu/Pd_documentation/x3.htm#s1.0. Some things are
outdated, misleading or just
Wow, thanks again Christof, this greatly improves my understanding of
Pd's engine.
Indeed, I never use callback mode because everytime I did in the past I
got some xruns, but had no clue about what was happening behind the scene.
I feel a bit ashamed, I'm pretty sure I could have figured this
