[PD] To pack or not to be packed that is the question ! (?)

[Derek Holzer]

Hello Meino,

please read the Generating Waveforms chapter again:

http://en.flossmanuals.net/PureData/GeneratingWaveforms

specifically the section titled "Using Sinesum".

You'll see that the third element of the "sinesum" message, where you 
have your $1 now, is the length of the table (which is set ahead of time).

The fourth element, your $2, is normally a value of "1". That is because 
the first harmonic is usually "1" when generating a bandlimited 
waveform. Of course, you don't have to fix it at "1".

But you do need to have the table length! So insert the number "2051" 
after the word "sinesum" in your patch, and you'll be set.

Best,
Derek
