#X text 14 271 To see whether the DSP is on or off , look at the checkbox
on the main Pd window. You can also turn the DSP on and off using that
checkbox.;
#X text 13 106 You can turn the processing of audio data on and off.
In order for your patch to run , you need to make sure that "compute
audio" is turned on. This is also known as the "DSP". There are a couple
ways of turning the "DSP" on and off.;
#X text 14 68 In Pd message processing is always running , but audio
processing can be turned on and off.;

#X text 7 373 You can make a triangle wave by setting each harmonic
to an amplitude that is the inverse of the harmonic number. That means
for harmonic 2 , set the slider to an amplitude of 1/2 , or halfway
in the middle. For harmonic 3 , set it at 1/3 , harmonic 4 , set
to 1/4 , and so on...;
