'Préambule' from 24 Pièces en style libre

There is a saying among users of the Hauptwerk model of the Riepp Heilig Geist organ: "Everything sounds good on the Riepp". One fellow Hauptwerker, who goes by the name 'PLRT' on the Concert Hall, challenged me a while ago to play Vierne on the Riepp. And a promise is a promise. So here it is, my apologies to the entire French republic and all admirers of Vierne.

A few small remarks.
Because I don't feel very much at home in this repertoire I searched for some proper recordings for a tempo indication. However, that didn't make things easier, since most organists ignore Vierné metronome mark and play it very slow or quite fast. Then I read somewhere you shouldn't take Vierne's metronome marks too seriously. Allright, it's every man for himself then...
Normally the Récit-parts sound further away, but here I played it on the Positiv (which is more direct), since I really needed the warm 8' stops of the more distant sounding Hauptwerk for the GO-parts. It's probably no secret that this organ has no swell pedal, so I ignored the few crescendi/decrescendi.
