+#X text 27 57 The pd~ object starts and manages a Pd sub-process that
+can communicate with the super-process (this one) via audio channels
+and/or Pd messages. In this way you can take advantage of multi-core
+CPUs \, and/or use Pd features from within Max (if you're using the
+Max version of pd~).;
+#X text 24 251 Sending a new "start" message will stop the sub-process
+and start a new one. If you just want to stop the sub-process \, send
+"stop".;
+#X text 33 353 Any message besides "pd~" is sent to the sub-process.
+For instance \, the message below sends "bar baz" to any object in
+the sub-process named "foo" \, such as a "receive" object.;
+#X text 43 430 Audio signals appear in adc~ objects in the sub-process.
+The sub-process doesn't open real audio devices.;
+#X text 281 473 Creation args:;
+#X text 265 490 -insig <n> sets input audio channels;
+#X text 266 508 -outsig <n> sets output channels;
+#X text 269 542 -fifo <n> sets round-trip delay in blocks;
+#X text 272 559 -pddir <s> sets Pd directory \, e.g. \,;
+#X text 299 574 .../Pd-0.42.app/Contents/Resources;
+#X text 272 590 -scheddir <s> sets scheduler dir \, e.g. \,;
+#X text 297 607 .../.../Resources/extra/pd~;
+#X text 267 524 -sr <n> sets sample rate;
+#X text 20 716 The first outlet reports messages the sub-process sends
+us via "stdout" objects. Any other outlets are signals corresponding
+to "dac~" objects in the sub-process.;
+#X text 10 784 ATTENTION: DSP must be running in this process for the
+sub-process to run. This is because its clock is slaved to audio I/O
+it gets from us!;
+#X text 359 849 Updated for Pd version 0.42.;
+#X text 24 138 Messages with "pd~" selector control the sub-process.
+"pd~ start" takes as arguments any startup arguments you wish to send
+the sub-process. For example \, specify "-nogui" to stop the sub-process's
+GUI from appearing. You don't have to specify the number of channels
+in and out \, since that's set by creation arguments below. Audio config
+arguments arguments (-audiobuf \, -audiodev \, etc.) are ignored.;
