#X text 33 501 Here's how you produce a sine wave out of Bela's stereo
output:;
#X text 33 611 Similarly \, Bela's stereo input can be addressed as
follows:;
#X obj 100 642 adc~;
#X obj 100 664 dac~;
#X text 177 653 Audio pass-through;
#X text 33 1581 Supported objects;
#X text 33 1591 -----------------;
#X text 33 1625 All native pd (vanilla) objects can be used.;
#X text 33 1611 By default Bela uses libpd to run puredata patches.
;
#X text 33 1645 It is also possible to compile pd objects to optimised
;
#X text 33 1658 C code using the Heavy Cloud Compiler \, in which case
;
#X text 33 1671 a different set of objects is supported (see below).
;
#X text 33 701 Analog I/O;
#X text 33 711 ----------;
#X text 33 731 Analog inputs and outputs are treated as audio signals
and;
#X text 33 745 are addressed using the next 8 channels of the [adc~]
and;
#X text 33 759 [dac~] objects:;

#X text 99 921 and;
#X obj 36 920 notein;
#X obj 125 920 ctlin;
#X text 183 921 objects can be used to interface MIDI devices;
#X text 33 939 with the patch.;
#X text 33 954 Most MIDI devices can be plugged into the Beaglebone's
USB;
#X text 33 968 port and can be used with these objects.;
#X text 33 839 See the 'BasicAnalogIn' and 'BasicAnalogOut' projects
for;
#X text 33 983 See the 'hello-midi' and 'midi-poly-synth' projects
for more;
#X text 33 997 for examples.;
#X obj 57 1058 print;
#X text 33 1058 The;
#X text 115 1058 object can be used to log messages directly to Bela's
;
#X text 33 1076 terminal output (e.g. as viewable in the browser IDE).

#X text 33 1208 Any signal can be visualised using Bela's browser-based
;
#X text 33 1222 scope. DAC channels 27 \, 28 \, 29 \, 30 address four
separate;
#X text 33 1236 scope channels.;

#X text 33 1710 Compiling Puredata patches with Heavy;
#X text 33 1720 -------------------------------------;
#X text 33 1740 As an alternative to libpd \, Puredata patches can
be;
#X text 33 1754 converted into optimised C code using the Heavy Cloud
;
#X text 33 1768 Compiler by Enzien Audio. The resulting code can result
;
#X text 33 1782 in large increases in performance and is therefore
well;
#X text 33 1796 suited for complex patches and final stages of development.
;
#X text 33 1810 We recommend to use libpd for prototyping and less
CPU;
#X text 33 1824 intensive patches.;
#X text 33 1838 See our documentation to learn more about compiling
patches;
#X text 33 1852 using Heavy \, and visit enzienaudio.com for more info
and;
#X text 33 1866 a list of currently supported objects.;
#X text 33 1401 Combining Pd and C++;
#X text 33 1411 --------------------;
#X text 33 1428 There are many cases where it is useful to combine
Pd;
#X text 33 1442 patches with C++ code \, for example when needing to
;
#X text 33 1456 incorporate system calls (e.g. networking) or for;
#X text 33 1470 sample-accurate dsp processes that are inconvenient
;
#X text 33 1484 to program in Puredata.;
#X text 33 1517 is used \, which functions as a libpd wrapper. It is
;
#X text 33 1504 When running Puredata patches a template render.cpp
file;
#X text 33 1531 possible to modify this file when starting a new pd
project.;
#X text 33 1545 See the 'CustomRenderFile' example project for more
info.;

#X text 33 1336 If you're viewing this patch using the Bela IDE you
can;
#X text 33 221 Patches can be drag-and-dropped into the browser IDE
;
#X text 33 235 and will be added to the current project that is open.
;
#X text 33 249 In order for the patch to run you need to fulfill the
;
#X text 33 263 following two requirements:;
#X text 59 285 a) The top-level patch needs to be named '_main.pd'
;
#X text 77 298 (you can still use abstractions);
#X text 59 315 b) Make sure there is no 'render.cpp' file inside;
#X text 77 328 the project. A template file will be used instead;
#X text 77 342 which acts as a wrapper for libpd.;
#X text 77 355 Alternatively you can modify this wrapper and place
;
#X text 77 368 it inside the project. See below for more information.
;
#X text 33 61 Puredata patches can easily be run on Bela. There are
two;
#X text 33 75 ways of doing this: using libpd (which is compatible
with;
#X text 33 89 the browser-based IDE) or using the Heavy cloud compiler
;
#X text 33 103 by Enzien Audio.;
#X text 33 123 This guide focuses mainly on using libpd via the browser
\,;
#X text 33 137 however most of the functionality is compatible across
both;
#X text 33 151 solutions.;

#X text 33 392 If you're viewing this inside the Bela IDE \, then you've
;
#X text 33 406 noticed by now that all pd patches can be previewed
within;
#X text 33 420 the browser. Note \, however \, that patches cannot
currently;
#X text 33 434 be edited or interacted with inside this preview.;
