Here is some documentation that covers internal pd messages.
(pd-msg_05)
1) Internal msgs are sent directly to pd (pd selector) or to a loaded patch (pd-patch.pd selector).
all these msgs have to end with a semicolon ";"
you can test them using :
the pd menu under "File : Message..." or with the shortcut <ctrl-m>
pdsend
the tclsend2pd in the 4.msg_from_tcl folder.
These messages allow you to:
control pd without the gui :
make use of the no-gui option
open a patch via socket... (tcl, python, sh, c++,...)
modify or create a new patch
create a patch that will create some other patch
dynamically create objects to create polyphony (e.g., 100 osc~ or more...)
load patches from within another patch
construct generative patches
create a new gui
and much more...
2) Here's a list of pd's internal msgs (* are documented somewhere in this doc):

3) Here's an overview of the documentation :
1.msg_and_patch
description of msgs that can be sent to patches.
(contains pd files)
2.msg_and_pd
description of msgs that can be sent to pd.
(contains pd files)
3.pdscript
an example sh scrip using pdsend to create a patch in pd.
pdscript was authored by Guenter Geiger
(contains it's own readme + files)
4.msg_from_tcl/tk
decription of how to use tcl/tk to create a patch, open a patch, etc...
5.Examples
examples of how an "obj x y myOsc~" message can be used
to deal with "massive polyphony"
4) Releases :
release 0.5 : pd-msg_05.tar.gz
added some more msg.
Thanks to Krzysztof Czaja
all msgs are listed for pd0.34
release 0.4 : pd-msg_04.tar.gz
added many messages :
the events messages
the menu messages
the cut&paste msg, etc...
complete the polyphonie example
release 0.3 : pd-msg
Rearrange patch & examples in different directory.
add polyphonie examples
add tcl scripts...
release 0.2 : self-generation
added messages to open and close patch.
release 0.1 : self-construction
first release
5) To do list :
some msgs are not well explained or not explained at all.
6) Reference :
Look @ the end of code of g_canvas.c in the source directory.
