Yes, they are both using the same interpolator, namely, Miller's poor 
choice of using a Lagrange interpolation, where each piece is part of a 
curve that goes through all four points, instead of picking what everybody 
else would pick, that is, a Natural Spline interpolation, which instead 
cares about the smooth transition from piece to piece (no sudden change of 
slope).

There is [tabread4c~] that uses natural spline. Is there a replacement for 
[vd~] already ? I'd like to compare, because my synth has a problem with 
high-pitched harmonics being way too loud and I'd like to know whether 
[vd~] is causing trouble there (it most likely makes a difference, but I 
don't know which difference yet).
