Rotating Object to Music Expression?

hello all,

 

i've been deep project long time , it's coming end.  have sound keys set 1 output. 

 

i looking rotate circle sound keys output, although not want circle move right 10 degrees move (-10 degrees), rather i'd continuously move clockwise output value continuously adds previous value based off time.  

 

is there expression cover that?  here's example of thought 'close' circle keeps going , forth rather continously around in 360 degrees. 

 

time+comp("main comp").layer("sound keys").effect("sound keys")("output 1")

 

i've attached screen shot guidance. 

 

thank help!

you have iterate on previous frames achieve makes expression pretty slow long comps.

 

var result = valueattime(0); for(var t=0; t<=time; t+=thiscomp.frameduration){     result += comp("main comp").layer("sound keys").effect("sound keys")("output 1”).valueattime(t) } result; 

alternatively, if want rotation happen in regular pattern @ each beat, can use tool beatassistant. generate keyframes , hence faster:
