looks very impressive!

When I try to start the application in OSX, I get this error:

Available Sketches in:

Oh yes, it's true!

I see the problem. is when loading data inside of jar file.
In eclipse all is OK, the problem is exporting sketch.

I uploaded a new version, with extracted files from jar file.
http://code.google.com/p/p4live/downloads/detail?name=P4live-osx-withbugs.zip
(Runs with bugs, you can not load sketchs.)

What is the best way for load xml files for GLTextureFilter in exported sketch?
I need to manually unzip each filter from jar file?

Thanks!

lot.

Ok, it works for me on OSX Lion. On Snow Leopard I get this error:

As for your question, my own approach is to put all the app resources in a data subfolder next to the app package:

app_folder

| p4live.app

\---> data

filter.xml

shader.glsl

blah blah

Hi giorgio,

I use midibus.
The library provides 3 methods, noteOn, noteOff and controllerChange.

You can use the method:
controllerChange(int channel, int number, int value)

and inside the method call:

yourVariable = map(value,0,127,minVariable,maxVariable)

Interested, but can't run the app in osx and the svn checkout doesn't contain real source files.

Hi,

I'd love to test your application in Windows 7 - 64bit.

However, when I click the .exe nothing happens. I've tried running in compatibility mode.

Cheers
