Re: [PD] Formant from SC in Pd?

[Alexandre Torres Porres]

BTW, here's an excerpt from Formant's code, found in here

from
line 2451

LOOP1(inNumSamples,
if (phase3 < onecyc13) {
ZXP(out) = (*(float*)((char*)sine + (((phase3 + tqcyc13) >> xlobits) &
xlomask13)) + 1.f)
*  *(float*)((char*)sine + ((phase2 >> xlobits) & xlomask13));
phase3 += formfreq;
} else {
ZXP(out) = 0.f;
}
phase1 += freq1;
phase2 += freq2;
if (phase1 > onecyc13) {
phase1 -= onecyc13;
phase2 = phase1 * freq2 / freq1;
phase3 = phase1 * freq3 / freq1;
}
);

"Formlet", the "FOF-like filter", is just a resonant filter with an
attack/decay envelope. I was able to replicate it. Though I get the idea
that the fof-filter thingy is based on a bank of such filters, huh?
"Formant", on the other hand, is described as an "oscillator", it
"generates a set of harmonics around a formant frequency at a given
fundamental frequency", has parameters for fundamental frequency, formant
frequency and bandwidth of the formant frequency.

I'm really curious on how to implement it as a pd patch ;) - but I don't
think I've seen anything like it in the Pd world.

Re: [PD] .pdrc?

[Peter P.]

Strangely neither setting 

-noautopatch

nor 

noautopatch

in my ~/.pdsettings disables autopatching. Specifying it on the command
line does work though. Can anyone else reproduce this?

best, P

Re: [PD] .pdrc?

[Claude Heiland-Allen]

Hi,

With no ~/.pdsettings, putting -noautopatch into my ~/.pdrc works as
expected. Tested with:

$ pd -version
Pd-0.47.1 ("") compiled for Debian (0.47.1-3) on 2016/11/28 at 20:56:10 UTC

~/.pdsettings has a strange format, more complex than ~/.pdrc - it's
meant to be edited and saved via the GUI.

Thank you! Feels good to have arrived in this decade.

In my case ~/.pdsettings was empty, hence pd didn't fall back to .pdrc

Does pd write into .pdsettings itself by the way? What if I don't want
that?

Oh absolutely! There is nothing wrong with it. I simply want to spare
me the extra click onto the canvas to de-select the currently created
object before creating a new one.

Thanks again, P

Pd's config-file on linux is called ~/.pdsettings for about a decade (or
longer).
iirc, it will fallback to ~/.pdrc, but only if it cannot find a
~/.pdsettings.

oh, and btw: autopatching is *really* nice (mostly).

[PD] .pdrc?

[Peter P.]

Hi,

I find that my Pd does do autopatching despite
-noautopatch
being specified in my ~/.pdrc which makes me wonder if that file is read
at all? Or has the name/location of pd's config file changed by now?
This is with Pd-0.47.1 ("") compiled for Debian (0.47.1-3) installed via
Debian apt.

Thanks!

Re: [PD] switch~ default off?

[Miller Puckette]

I'm holding off on this until I can do it coherently with two other
extensions I'm planning to the switch~/block~ objects (to allow multichannel
signals and to manage sample rates better).

cheers

I have no intention of updating GEM for OpenGL ES and/or to support GEM on iOS. 
It’s definitely *possible* but beyond my current time, energy level, and 
personal project requirements.
