n=0;

if(numKeys >0){

n=nearestKey(time).index;

if(key(n).time >time){

n–;

}

}

if(n==0){

t=0;

}else{

t=time – key(n).time;

}

if(n>0 && t<1){

v=velocityAtTime(key(n).time – thisComp.frameDuration/10);

amp=.05;

freq=4.0;

decay=8.0;

value+

v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);

}else{

value;

}

I will add more when I come across anything new.
