Which version of Pd are you using?
vanilia 0.41.4
I'd like to see the waveform and test it out. Here's my analysis of key points
(a=x[-1], b=x[0], c=x[1], d=x[2])
83 a0 = d - c - a + b;
84 a1 = a - b - a0;
85 a2 = c - a;
86 *out++ = ((a0*frac+a1)*frac+a2)*frac+b;
At frac=0, output should be b. Check!
At frac=1, output should be c
((a0*1+a1)*1+a2)*1+b
=a0+a1+a2+b
=d-c-a+b + a-b-(d-c-a+b) + c-a + b
=d-c-a+b + a-b-d+c+a-b + c-a + b
=d-c-a+b + 2a-2b+c-d + c-a + b
=c
Check!
1st derivatives:
At frac=0,
d/dx f(x) = c-a
(This quantity really ought to be (c-a)/2, but let's see how the rest comes out)
At frac=1,
d/dx f(x) = 3*(d-c-a+b) + 2*(a-b-d+c+a-b) + c-a
=d-b
So, we've got 1st derivatives that match between samples. Check!
This looks like a really good plan. I might suggest some new
coefficients to try:
a0=(3b-a-3c+d)/2
a1=a-5b/2+2c-d/2
a2=(c-a)/2
ok, i don't have time for now to test anything.
i'll have more time in 1 or 2 weeks.
The only difference is the 1st derivatives are (c-a)/2 and (d-b)/2,
respectively.
Maybe you could try a 5th-degree polynomial next and set the 2nd
derivatives for continuity. This would involve 4-points as before,
but it might introduce a ripple in the interpolation (cubic
interpolation can't do that, since it only has two critical points).
i tried a Hermite interpolation.
it sound great, but i did not had time yet to explore the tension parametter.
here is the code if you wish to explore it.
I'm not keen on doing the spectral analysis, because it would take
about 4 hours, to do it by hand.
There's something I would like to see (once I can compile it). I made
a patch (attached) a while back to view the tabread4~ interpolation
function (impulse response). Give it a try if you're inclined to do
so, because it might surprise you.
attachement is a pict of the impulse response of tabread4~ and tabread4c~.

Re: [PD] ~/pd or ~/.pd for user's externals directory
An official folder would be ok. But it should be possible to reassign this variable if necessary. In my case I have the work folder /jmmmp-ext in the extras folder (where is also a jmmmp folder from pd). That allows me to get to my work much faster than having something on my system user folder. When I update pd, it always overwrites everything but this folder, evidently.

Re: [PD] ~/pd or ~/.pd for user's externals directory
No. Hidden home directory files traditionally have a special meaning. They are initialisation resources. ~/.something is a place a program will go to look for startup options (in a particular order after /var/something ... so that global and multi user configs can live together) I know some recent Linux apps have started putting userworld resources into dot directories, but this is bad practice imho. 2c andy.

Re: [PD] ~/pd or ~/.pd for user's externals directory
Hans, While I don't really have any feelings about this external directory, it would be nice to have a different properties file from what Vanilla Pd uses, this way we can have two different setups, and they won't interfere with each other. Currently, I have one properties file that both versions of Pd appear to be trying to load, but because the properties file was built for Pd-extended, loading Vanilla Pd generates errors for everything that it tries to load, as it can't find those things.

Re: [PD] sssad and polywavesynth
hi Luigi could you pack the synth in an abstraction and give it an ID as arguemnt? then u could use the $1 as prefix for all your parameters and sssad. but this way you can't load a preset from the other instance. this problem could be solved with OSC or a list for each parameter. i.e. synthA/freq 123 or synthA freq 123 good luck :) eni Luigi Rensinghoff wrote: Dear List If someone also uses the great Polywavesynth.well i have a little weird problem..
