@solipp Thank you!

I love the way that Audiolab modules look and work. Thank you for making it! I'm trying to use pp.eqfilter~ as a notch filter. When I close and reopen the patch, I have to reset notch and the other parameters. Is there a way to get it to remember my settings? Thank you!

@porres Thank you!

@porres I tried the paf~ that solipp linked to, and it seems to be exactly what I'm looking for. How would I get the Windows version of vosim~ from github?

@porres It's exciting to see progress on this! Thank you! I don't have time to try vosim~ today, but will definitely try it tomorrow.

I just downloaded Audiolab to get pp.spectrum~ and I love it! Thank you for making this.

F12.paf.control.pd says that there is a paf~ external, but I can't find it. This page by Miller Puckette describes paf:
https://msp.ucsd.edu/techniques/latest/book-html/node96.html
Max/MSP has a paf~ object.
I just saw that you opened an issue on paf~
https://github.com/pure-data/pure-data/issues/1685

The vosim page is here: https://kaegi.nl/vosim
Shadylib includes a voisim~ object. Shadylib isn't on deken and doesn't have a Windows version. https://github.com/sebshader/shadylib/releases/tag/2.0
Max/MSP has gen~.vosim.maxpat

Here is some background on fof, including Faust code: https://ccrma.stanford.edu/~mjolsen/220a/fp.html
Max Sound Box has Chant objects which include fof: https://forum.ircam.fr/projects/detail/max-sound-box
Csound has an fof operator. https://csound.com/docs/manual/fof.html
and an fof2 operator https://csound.com/docs/manual/fof2.html
Here is a tutorial on using fof in csound: https://www.eumus.edu.uy/eme/ensenanza/electivas/csound/materiales/tutorials/fof/fof.html

If you only do one of these, I think that paf~ would be the best. Thank you for looking at this!

The formant module in automatonism uses parallel bandpass filters, which is what I'm currently doing. I'm looking for alternatives to the bandpass filter approach.

I'm currently using an oscillator that has high levels of harmonics filtered by several bandpass filters in parallel to generate formants, and that works pretty well. I'm interested in other ways of generating formants. I've seen old references to fof~ and vosim~, but these objects are old and apparently unsupported. Does anyone know of current versions of these? Or other ways to generate formants in Pd?

Thanks @willblackhurst and @lacuna for showing how to use savestate with an array.
