;
#X text 4 294 USING [SPIGOT] TO CREATE A GATE.;
#X text 14 312 Unlike its closest cousin MAX \, Pd does not have a
native [gate] object. There are other Pd libraries which include gates
for both audio and numerical data \, but similar routines can be built
in Pd using [spigot]. The example below shows a two-way gate using
two [spigots] and the [expr] object.;
#X obj 87 505 spigot;
#X floatatom 88 459 1 0 0 0 - - -;
#X text 105 458 controls: open and close the gates.;

#X obj 118 484 expr 1-$f1;
#X text 24 398 Click to start sending info through the gates.;
#X obj 88 439 loadbang;
#X text 8 38 [spigot] passes messages from its left inlet to its outlet
\, as long as a nonzero number is sent to its right inlet. When its
right inlet gets zero \, incoming messages are "blocked" (i.e. ignored).
;
#X text 6 231 [spigot] works essentially like a doorway. When the door
is open \, messages can pass through. When the door is closed \, messages
are ignored. By default \, the door is always closed!;
#X obj 23 505 spigot;
#X text 5 547 In the example above \, the magic is created by the [expr]
object which performs a simple calculation using the incoming number
(1 or 0). Note that the figure "$f1" is a variable which assumes the
value of the incoming number.;

#X obj 567 98 spigot 0;
#X text 434 216 [SPIGOT] FOR AUDIO SIGNALS?;
#X text 447 233 [spigot] does not work with audio signals. The data
types which are accepted by this object are floats \, symbols \, lists
\, bangs \, anythings and pointers. However \, audio signals require
a completely different treatment.;
#X text 444 285 Pd does not have a [spigot] for audio signals \, but
the same effect can be created using the following structure:;
#X obj 458 332 osc~ 800;

#X text 487 406 is effectively blocked.;

#X text 18 86 These objects are offered in Pd only if you have downloaded
and properly installed the appropriate library. These objects may or
may not exist in a single library.;
#X text 17 135 The best places to find information about Pd's libraries
is:;
#X text 14 157 www.puredata.org and click on "Downloads" then "Software"
;
#X text 15 173 or;
#X text 16 187 iem.kug.ac.at/pdb/;
#X restore 459 539 pd related_objects_from_other_libraries;
#X obj 456 188 spigot cat;
#X obj 534 188 spigot dog;
#X text 454 33 [spigot] only accepts one numerical creation argument:
a one or a zero. At creation time the [spigot] is "closed". With a
one \, its defaults to open.;

#X text 451 576 This document was updated for Pd version 0.38-4. It
was edited by Dave Sabine and Hans-Christoph Steiner as part of a project
called pddp proposed by Krzysztof Czaja to build comprehensive documentation
for Pd.;
#X text 455 143 [spigot] used to accept any symbol \, but all of these
are meaningless and have no effect on the operation of the object.
This was removed in Pd 0.38-3;
