The tempo of David Siu's midirecording is higher as usual, so the Prélude lasts only 8.39 instead of 10 or 11 minutes of the usual interpretations.
I registered the recit, which carrys the melody in the right hand differently than C. Franck with a tremulant. And I registered the third part quite differently than C. Franck in his orginal sheet.

So the grand organ in the left hand sounds dominant and the main theme which comes from the recit in the right hand sounds more in the background.
This gives this recording of the Prélude a special character, because due to the higher tempo and the unusual registration of the grand organ in the left hand, the Prélude in the third part sounds a bit as if Keith Emerson were sitting at the organ...

But this is also due to the enormous variety of registration options and sounds of the registers of the Organteq models.

Hope you enjoy this wonderful piece of organmusic!

And here comes a second version in normal tempo and without the tremulant for the leading voice.

For this audiorecording I used the Romantic Cathedral-FXP.
