#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.;

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
