You need to have Pd (0.43+), Pure (0.18+) and the pd-pure plugin
(0.4+) installed to run these examples. The waveplay patch also requires
libsndfile, the bounce patch needs Gem.
Pd and libsndfile are readily available on most Linux systems. Gem you may have to compile from source, but it's also included in some distributions of Pd, such as Pd-l2ork and Purr Data. Arch and Ubuntu packages for Pure and pd-pure can be found on the Pure website, but are also easy to install from source.
A simple soundfile player. The accompanying Pure script is in wavefile.pure.
Run this is as pd -lib pure waveplay.pd and push the toggle button to
play. You might have to adjust the window size to get rid of dropouts.
A bouncing ball animation. Run as pd -noaudio -lib pure -lib Gem bounce.pd.
First push the "Graphics window" toggle to start rendering, then the "Bouncing
ball animation" toggle to start the animation.
The second patch adds some sound effects. Run this as pd bounce-sound.pd and
push the toggle above the pd sound subpatch in the main patch to connect the
two patches. (These are in two separate patches connected via netsend/
netreceive to prevent audio dropouts, see the Gem FAQ for details.)
Try the different acceleration values (corresponding to the gravity of the Moon, Earth and Jupiter). You can also click inside the Gem window to restart the animation at different positions.
The Pure script implementing the motion of the ball is in ball.pure.
