is it possible to control SS by any determined pitch?
i want to say that SS is changing maybe the direction by any Beat in a determined pitch, by any other pitch it should change the size and and and...

ist this possible? and if yes, how?

do you mean like the bass does "x=x+sin(a+.001)"
and the midrange does "y=abs(x)"
and the treble does "a=cos(a*1.5)"?

what is a?
and how should i use this to see what it does? can you show me a example how it works?

another example what i want is that if the song has more bass, the colour is maybe a deep blue, if there's more treble, the color is yellow..

i hope you can help

first of all, a is a variable
and that i wrote was just a example
but i just wanted to know what you meant?

but i don't know actually how to do it

I assume you have a SS that is moving around by some means, and that you want it to change it's direction of movement every low-pitch beat; and, that you want it to change size every high-pitch beat, correct?

You can use getspec() to grab sound data. You can grab individual spectrum points as well as averaged areas (using the width parameter) to get a general 'bass' or 'treble'.

Geozop, your assume is the right kind.
UnConeD, i didn't really know, how to use the getspec the right way, to become the SS i want.. i will make an example...

i make a simple SS

init:n=400

frame:t=t-0.05

point:x=cos(t);y=sin(t)

init:
n=400

frame:
s will control the size of the ring
s=if(above((getspec(0.1,0.2,0)),0.4),0.5,0.9)
s is 0.5 if the specdata at the specified point is higher than 0.4 otherwise it will be 0.9

per point:
t=t-0.05;
x=cos(t)*s;
y=sin(t)*s;

PS:
if you use
x=(cos(t)*s)/(w/h);
the ring will apear as a ring even when the display is a rectangle(but only until w>h)

Because a division is an expensive operation, it's best to save a var "af=w/h" in OnFrame and use y=y*af instead of y=y/af (multiply is faster).

thanx for help
thanx to T-Cut and UnConeD, that was very helpfull, so i can use it. is it also possible that the ring walks between the outer and the inner rig?

you can ses the preview of my new work with this codes
