Mutable Veils Question

I need a VCA for CV modulation, and Veils seems fantastic. Before I purchase, I’d like to know when to use the exponential curve vs. when to use the linear…all the MuffWiggler posts on the issue are confusing me. Would anyone graciously school me on this?
Thank you!

You just trust your ears. It’ll depend on the shape of the modulation signal sent to Veils’ CV input anyway - for example if your envelope already has an exponential curve, you might prefer setting Veils’ curve to linear so that the composition of the two isn’t too steep.
