Good Day,
I want to change the volume of a source, but not linear or formula. More like with an array as an input, where I interpolate between the values. Something like this: But in this implementation the output just jumps between the values in the array of course.

I found Fader or Interpolate1D between 2 Values, but nothing like this with an array.

Perhaps there is something I am missing and there is a better approach or has an Idea how to interpolate between these values?
Cheers polle.

@polle if you want to use linear interpolation you can make your own linear interpolator. I feel like there might be an external to do it but can't think of it.

And [tabread4] and [tabread4~] do Lagrange 4-point interpolation.

If it has to be exact, this helps: https://forum.pdpatchrepo.info/topic/14301/add-delete-guard-points-of-an-array-for-4-point-interpolation-of-tabread4-ect

And [cyclone/wave~] has more implemented, such as cúbic, spline, Hermite

@seb-harmonik-ar thats a really neat solution, thanks for your help!

@lacuna tabread4 is also a good idea, thanks!
