Hello,

Anybody know what is the meaning of this value ?
What kind of formula is it supposed to define ?

I try to achieve the French translation and i'm a bit lost with that.

Thanks.

Hello,

With this message : [foo cosinesum 64 1.(

all values of foo array are set to 1.

While with this one : [foo sinesum 64 1.(

i have the expected simple sinus drawn ; is it a bug ?

(i'm os X.4.11 with Pd-vanilla 0.43-1test5)

Hello,

yes, you fix it for me

Hello,

wow, thanks, i should have never found !

Hello,

sorry, it is in the properties of the number UI [nbx] (Pd-vanilla).

Hello mod,

you are right, and and after a good night it seems obvious why :

cosinesum : a0 * cos (0. * x) + a1 * cos (1. * x) + a2 * cos (2. * x) + ... + an * cos (n * x)
sinesum : b0 * sin (0. * x) + b1 * sin (1. * x) + b2 * sin (2. * x) + ... + bn * sin (n * x)

for cosinesum, a0 * cos (0) = a0 ; while for sinesum : b0 * sin (0) is ALWAYS 0 ; so you don't have to give the b0 amplitude, list of amplitudes start with b1 in case of sinesum.

it is not a "bug", it is normal behavior ; i'm not sure it is a very intuitive approach ; better to keep the same logic (for math noob like me) ? ; but anyway it seems this is the common way ...

Hello,

quick look in sources and it seems there is no DC in case of sinus as in this applet ...

... i don't know why ; anybody ?

Anyway thanks for reply.

Hello,

i used maxMSP during several years to explore generative music ;
i switched serously with pureData last week because :

• pureData's BSD licence and libpd project ; In DAWs, you can't code your own algorithm and so (machine-learning, IA ...) ; with M4L perhaps (i don't really know it) but you are not free to reuse what you do everywhere you want ; Of course that's something you don't think about when you start learning but, the day you will code externals in C/C++, it is.
• pureData run on linux ; actually i'm a macintosh user ; but as i'm fed up to give money each year for planned obsolescence i only buy second-hand computer now and pureData is perfect for that.

my 2 cents.
