Re: [PD] OpenFrameworks + ofxPd in android: can't modify patch

[Jose Luis Diez Antich]

Hi Dan,

Thank you for your answer.

What do you mean by “modify it”? Modify the patch? The ofApp? You mean you
> send messages to the patch or?


I mean modify the pd patch, sorry if I was not clear. At the moment, in the
patch noisepanning.pd, there is an [osc~] connected to the second inlet of
[headShadow].
Then, I modify the patch so the input to this second inlet is a constant
and I build the app again (running: make AndroidDebug and ./gradlew
assembleDebug). When I install the new version of the app in my phone, the
behaviour of the app is exactly the same as before, as when there was an
[osc~] object.

I hope my problem is more clear now :)

Does the sound work in the example if you build and run it on Android? I

I have not tested an example, but the application I built runs on android.


I am not sending anything from ofApp.cpp at the moment, but that is the
next step, once I sort out how to modify pd patches.


Thank you for your time,
jl

[PD] OpenFrameworks + ofxPd in android: can't modify patch

[Jose Luis Diez Antich]

Hi,
I have a problem with openframeworks ofxPd, maybe you can help me:

I have built an android application that uses ofxPd to interface with pd.
The code can be found here .

At the moment, I am loading a pd file called "noisepanning.pd", I load it
in the ofApp.cpp
 source code
file. The problem arises when I try to modify it, because the app behaviour
does not change, it is like I have not done anything. Moreover, when I try
to load another pd patch, the android app does not sound at all.

I am not building again with Xcode when I perform these changes, since I am
only interested in the android application. I only use the commands:

make AndroidDebug
./gradlew assembleDebug

Is there something more I should do when I change the pd patch?

Thank you very much,

jl

[PD] Building and packaging externals for android

[Jose Luis Diez Antich]

Hi all,
I need help building and packaging externals for android.

I am following [1]. So far, I have:
- added my external code "IIDgains.c" in the folder PdCore/jni.
- modified the android.mk in the same folder, and it looks like this:

include $(call all-subdir-makefiles)

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := IIDgains
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../PdCore/jni/libpd/pure-data/src
LOCAL_CFLAGS := -DPD
LOCAL_SRC_FILES := IIDgains.c
LOCAL_LDLIBS := -L$(LOCAL_PATH)/../../PdCore/libs/$(TARGET_ARCH_ABI) -lpd
include $(BUILD_SHARED_LIBRARY)

Doing that does not work, but I have not found any other information about
it. What can I do to solve it?

I do not know what they mean in "The only additional step that's needed is
to add the location of the binaries to Pd's search path, but if your
project uses PdService, you already get that for free."

What do they mean with that? What should I add more to my app in order to
make an external work in it?

Thank you

Re: [PD] About extending the Universal Polyphonic Player

[Jose Luis Diez Antich]

Hi Thomas,

Thank you for your answer, it's been helpful!

Now I'd like to figure out how to modify the message in order to be able to
select from it with a [route] object.

Thanks!

[PD] About extending the Universal Polyphonic Player

[Jose Luis Diez Antich]

Hi,

I found the Polyphonic Universal Player [1], I really liked it, and I would
like to ask you about it.

- I would like to build a simple classic synthesizer, that you can change
its waveform, filter and envelope parameters. How could I send these
parameters to my voice? In the patch '4-noteoff.pd', I understand that you
send the ADSR parameters with a list that you call tag, is it possible to
create a tag thus I can use the object [route] to get each different
parameter from it? Do you have an example of a similar simple synthesizer?

- I do not understand how the subpatch [spat mono] works, could you explain
it?

Thank you very much for your attention,
jl
