pitched skips

[M.v.Strien]

Hi list,

I'm working on a lilytracker, which is basically a tracker like it's 
described here: http://en.wikipedia.org/wiki/Tracker  but then without 
playback, samples etc. It's for me the best of 2 worlds: drag/drop until 
eternity in visual tools and low-level programming in lilypond, and it's 
really fast! This tracker is actually nearly done already. To make sure I 
can put articulations, dynamics etc. on each step without having to do an 
extreme load o' intelli-code and other scary stuff, I'll be needing the 
skip command so that stuff can be placed everywhere. The dynamics command 
in the user tutorial was my starting point regarding that method. The code 
below works:

{
\relative c

<< {f4 a8 bes c d e f}
\\
{ s16 s s s  s\< s s s\!  s\> s\pp s s\!  s\< s s\! s\ff  } >>

}

However, the skips aren't pitched and so whatever's alligned to that pitch 
will be on the same heights everywhere, and in this case it'll pinch just 
through all the notes on that channel. Is it somehow possible to have 
pitched skips (I would be doubling the notes in my skips section, kinda 
lika having f16 f f f a a bes bes c d e f) so that any alligned stuff would 
be at the correct height?
