AFAIK, both, [vd~] and [tabread4~] do a 4-point interpolation. Or am I overseeing something?
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).
