And not very easy to play.
I heard it for the first time in a concert at ST SERNIN (TOULOUSE, FRANCE). As you kwon, in romantics organ we have'nt "combinateurs" (I don't known word in english) and for this concert I "tirer les jeux" : push the stops ? 25 years ago.
And 25 years after, i call X......... for the score and, in remind of this concert, he got me. Really a quality man.
