Fantasia su Victimae paschali laudes

Piece written for an organ composition contest in 2019 (not yet published).
In writing it I used Giubiasco's sample set, but after trying it on several of the sets I own I preferred this version with the softer sounds of Lipiny's organ (thanks to Piotr Grabowski!).
MIDI execution directly from the score is a bit mechanical: I hope everything is understandable.
