Hi,
I'm trying to find a convenient way to fill up the partials in a sinesum message. My intention is to create several more complex waveforms.
I wrote the following patch which I attach, for generating a sawtooth (1/n). It doesn't work and I guess its because I'm not familiar with using lists. I wanted to get 30 values and append them one by one to get a list, then send the list into the sinesum message.
my questions:

1. Is it possible to fix the patch so it can work, using

?

2. Looking for a more elegant way to do the same thing...

Thanks a lot!

You're on the right track! Here's my take.

The way to use a

or to build up a list like you're trying to do is to cross-connect it with a , as shown in the attached. Note also that the order the list builds up in depends on whether you use or - prepend is the correct choice for this situation (I can never remember which one to use, though, and always just have to trial-and-error it). Then you store the results in a [lister] (I think on its own actually also works for this, if you don't have [lister], but I prefer it) until the list is finished and ready to be used. And remember to clear out the contents of the and by sending the a [list( message at the end of each usage.

Hi Stutter,
Thanks a lot, it works great. I'm curious about the [lister]...it receives a list to its right inlet. how does it know when to output it?

Anyone knows if there's a way to replace all the variables ($1-$30) in the sinesum message? If I want to make 100 variables, would I still need to write them one by one?
thanks a lot

The helpfile for [lister] says it is deprecated since the

object was created, so it's probably best to avoid it on the off chance that it won't work in the future.

With both and [lister], it stores the list received in the right inlet and outputs it when it receives a bang in the left inlet. Just like [f ] does with floats.

You can get rid of the $ variables in the message box by using :

<-- the one that stores the list of amplitudes

And then send the [normalize( message after that.

Didn't know that lister was deprecated. I still use it, though, I guess because I feel like it's a better analogue to, for example, [f ] than

is.

I attached a patch here for clarity.

Just curious, why do you say that?

hi Maelstorm,
Thanks! I attach the new version. How do I incorporate the final list (with the sinesum and all the amplitudes) into the [; array] message? I couldn't figure that out.
Thanks for the help,

just saw your patch, Maelstorm...I understand now. Thanks

Uh, actually, now you ask, I'm not 100% sure. I think I partially preferred the way it handled bangs, but also maybe I just preferred it because I came across it first, as [l ] is aliased to [lister] instead of . I guess I'll lose it now that I know it's deprecated.
