Passacaille in C minor

Recently, I found in my computer an old demo version of Wildervank. Only a few stops were available but the entire sampleset was present in the package. I restored the full organ and found it so beautiful that I wanted to record again some of my earliest compositions with this organ.
I precise that this first set of Wildervank was under Creative Commons license, so modifying the ODF is allowed.
This piece was composed in 2007.and revised on March 2015.
