Additionally, it is important to consider velocity along the curve.
Based on the positioning of the control points, we may be walking at
times and running at others. You see this with the variable spacing of
dots when you sampled

Beziers are one way to generalize simple linear interpolation to higher
orders, and they have a rather curious recursive relationship

Hi Harm,
Well, it's a little cheating involved :)
LilyPond does checks for grob-properties, you can't write
\override Grob.self-invited-property = ...
without "explaining" this `self-invited-property´ to LilyPond.
But details and bound-details are established properties taking alists

One question I really couldn't answer is:

Seems not to be a x- or y-value, not an arc-length-value .., but what
else?
"t" is the standard name for the control value of

Thanks a lot for your help!
Moving the Midi_control_change_performer did the trick (I was unaware of its
existence).
A MWA that actually works is then:
\version "2.19.82"
\score {
\new Staff <<
\new Voice \relative c''' {
\set midiExpression = #.1
\voiceOne
g1
Hi Aaron and Harm,
I started to implement the functionality, finally I more or less
rewrote anything.
As David K once said: rewriting all means at least knowing where the
bugs are...
There is an annoying optical issue where using the angle of the curve
at the end points does not work well
