convert relative to absolute...

[Julian Peterson]

I have a project in which I am training a computer to improvise in the 
same style as an example piece of music.
I wrote a little program in supercollider to take a sequence of lilypond 
notes, learn patterns from them and then generate
output for lilypond to render into a score.
The material I would like to feed it is written using /relative , but 
for my script to work I need it to be in absolute pitches.  Is there a 
script or method for doing this?

In other words, I would like to convert:

/relative c'' { c d e f g f e d c g c g c}
to
{c'' d'' e'' f'' g'' f'' e'' d'' c'' g' c'' g' c''}

Any ideas?

Thanks,
Julian Peterson
