Hi there,

I made a patch for the reactable that plays samples and allows to tune pitch and playback speed.

It's great fun to play with this patch on a reactable, but if you don't have one, you can try it with the reactivision TUIO Simulator.

It's over here :
http://git.tetalab.org/index.php/p/puredatareactable/
in "Source"
The latest version is in 0_lamixette_current_latest or in lamixette_06. There is a zip file that will download everything you need.
Have a look at the readme files.

There is a screenshot at the Source root directory.
There are some videos on lucas' channel on vimeo :

I am quite new to pd so you might find the code not that smart.
If you have good ideas to improve this patch, please tell me.
I'd like to thank the people who share patches here as I have reused parts of some.

hi there,

I've got pd running fine for sounds but I'ld like Gem (for a reactable); but I've got this error at pd startup :
Gem: can't load library

I am with Fedora 10,

kernel :
$ uname -a

Description: Pd gives you a canvas for patching together modules that analyze,
: process, and synthesize sounds, together with a rich palette of
: real-time control and I/O possibilities. Similar to Max
: (Cycling74) and JMAX (IRCAM). A related software package named Gem
: extends Pd's capabilities to include graphical rendering.

Here is what pd tells when started with "pd" :

I can't locate files like Gem-meta.pd or Gem.pd_linux on the computer;
I keep investigating, but any hint is welcome, thanks

# yum install pd-*
seems to have solved the problem, sorry for the noise :
