This is great to know; i will try that.
To answer your question, I do not have this latency issue in the editor.
Even more importantly, I don't have this issue when i build the same Pd
patch for android, using the libpd4unity approach, as i've done here:
https://github.com/cmuartfab/libpd4unity-starter

Good to know; thanks scott.

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:

https://github.com/marcinkaszynski/kalimba

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.

best,
scott

Hello all,
This is wonderful, thank you for contributing to this thread. Glad to see
that Unity + PureData is active:

@wing: I also put together a unity+pd integration example; it has a
bouncing ball withs sonification done in Pd; works on Android!
https://github.com/cmuartfab/libpd4unity-starter  I will take a look at
your work also, thank you for sharing that.

@scott: I also tried Kalimba, but i have massive latency on Android, on the
order of 300-500ms.  Did you have this experience?

@scott+@wing: can you give me an example or two of when you may need
multiple instances of LibPd in one's unity project? Couldnt you just make a
more complex Pd patch that has all the things you want happening in it?

Re: [PD] libpd for Unity still alive?

Hi Scott,

The way I handle multiple instances is to open new patches via C# and store
the dollar zero variable in a game object.

The PdAudioSource component can be attached to a prefab and you can
instantiated the prefab via C#. PdAudioSource also stores the dollar zero
variable of the associated patch, so you can directly send messages to a
particular instance by calling methods in PdAudioSource. However, all send
and receive objects in your patches need to start with a dollar zero (e.g.
[send $0-Frequency], [receive $0-isPlaying]).

For audio signals, all patches need to have appropriate [throw~ ] objects
(e.g. [throw~ out5] [throw~ out6]) in order to be heard. Audio signals from
all instances will go through the [catch~ ] object in pdManager.pd, which
is mapped to the Unity audio mixer. Getting audio input from Unity to libpd
is a little bit tricky in this case. If someone need audio input from
Unity, one might modify the OnAudioFilterRead method in PdStereo.cs.

My project isn't complete and I always welcome for suggestions or comments.

Best,
Wing
