Android latency is often a fact of life, even by that much. one question is
whether you're getting that latency playing it in the Editor. if not, that
may be a libpd question that would need answering. you might also reach out
to Sebastian(hagish) to ask him, though he might be no longer working with
libpd since Kalmiba wasn't updated in a while. he did in fact say that
Android latency was an issue in the Read Me. however you might have more
luck with this fork which has a latency fix in Android. not sure how good
it is, but it's been updated about a year ago:


if you are getting latency in the Editor, i'm not sure what to say. i
haven't tested latency yet (midterm grading wiped my weekend out).

@ali - as i understand it, creating instances of PD/libpd has been
discussed for a while as a positive step. i haven't had a need for it yet
but others on this list have discussed benefits, mostly in terms of both
power and resource management. there are drawbacks as well, but
unfortunately i don't know the particulars. one instance is enough for me
for the moment though. but i think the strength is dynamically spawning and
killing resources as needed.
