<p>Readers of this book should have Pd installed on their computer
so they are able to try out the processes described. Without this
simultaneous practical experience, this tutorial will be difficult to
understand.</p>
<p>First you need a computer with at least 128 MB main memory, a
500 MHz processor and ca. 500 MB hard disk space (these are the
absolute minimum requirements!). Pd works with the following
operating systems: Linux, OS X, and Windows.</p>
<p>Then you need to download the newest version of Pd-extended
from the Internet. Enter "Pd-extended" into an Internet search
engine. Since the address for the download portal may change in the
future, no link to the site will be provided here. Pd-extended is a
version of the original software (also called "Pd vanilla") that has
been expanded with numerous libraries. Most of the exercises
described here work with the original version of Pd, but not all of
them. The extra objects in Pd-extended make the program much more
practical in general. This tutorial assumes Pd-extended version 0.39
or higher.</p>
<p>
Once Pd has been installed, we open it from the directory Pd/bin/. A
window appears. This is the main control center, so to speak. Here
you can test whether Pd is functioning properly: In the main menu,
click on <span class="strong"><strong>Media</strong></span> <span
class="strong"><strong>Test Audio and MIDI</strong></span>. Under
"TEST SIGNAL", click first on the box next to "–40", then on
the box next to "–20". You should hear a sine tone coming out
of the computer's loudspeaker (A4). If you do not, then you need to
adjust your hardware settings (under <span class="strong"><strong>Media</strong></span>
<span class="strong"><strong>Audio settings</strong></span>). More
information regarding problems that arise at this stage cannot be
given here. For help resolving any problems, please consult the
"Pd-list", a forum of Pd users on the Internet. If a microphone is
connected, the digits in at least the leftmost two boxes under "AUDIO
INPUT" should change in response to sound picked up by the
microphone. As long as the test tone is working, you can work with
the program without a microphone. (By Chapter 3 at the latest,
however, you will sometimes need a microphone.)
