Hey I'm going through the literature and fell in a gap. I can't get this patch to output. It's included with pd-extended and is filed under Browser/Manuals/1.Sound/sixteen_harmonics.pd.

the console is saying either ": no such object" or "$1: symbol needed as message destination:"

It looks like the message box trigger and array are assigning $1. but I don't quite understand how they are supposed to interact.

Googling/searching was fruitless

thanks~

@trumpetfish1 Hello and welcome to the forum.
Indeed, the $1 is the problem.
[sixteen_harmonics] is what we call an abstraction...... a patch that can be used many times inside another patch.
So that it can be used many times without conflicts between each copy it has been given a variable for the name of the array....... $1
It was designed to be used by the patch (in the same folder) building_waveforms_with_sines.pd
If you open that patch you will see that [sixteen_harmonics] has been given what we call an "argument".
In this case the argument is "wavetable" and as the patch is opened the $1 within [sixteen_harmonics wavetable] has been replaced with wavetable.
You don't see that change but if you open [sixteen_harmonics wavetable] you will see the patch you had trouble with working...... and if you put a [print] after [symbol $1] it will print "wavetable" to the terminal as you move a fader. The $1 in the following message will then also be replaced by "wavetable".
BEWARE $1 in an object and $1 in a message have different purposes...... see the link below...!!
It is a very powerful feature that you should know about and will let you build much faster and more easily once you understand it...... https://forum.pdpatchrepo.info/topic/9774/pure-data-noob/4

OK I got it now, was hung up on 0$ but the FLOSS manual cleared it up. Thanks!
