  keep the keyframe curves)

  I have an expression that lets me substitute the value of one keyframe with values from a point control or slider. This is the expression, which I originally found here (all the way at the end of the page, thanks Dan Ebbert!):

  var newValue=thisComp.layer(“Tief-Blau Farbfläche 1”).effect(“newValue”)(“ADBE Point Control-0001”);

  var firstValue = key(1).value;

  var lastValue = key(2).value;

  if (firstValue[0] < lastValue[0])

  x = linear(value[0],firstValue[0],lastValue[0],firstValue[0],newValue[0])

  else

  x = linear(value[0],lastValue[0],firstValue[0],newValue[0],firstValue[0]);

  if (firstValue[1] < lastValue[1])

  y = linear(value[1],firstValue[1],lastValue[1],firstValue[1],newValue[1])

  else

  y = linear(value[1],lastValue[1],firstValue[1],newValue[1],firstValue[1]);

  [x,y]

  What I’m looking for is an expression that lets me do the same for a variable number of n keyframes. I guess it could be done with a “for -> each-loop”, but my own humble expression-whiz doesn’t cut it and so I’m stuck. Does anybody have an idea?
