This is a virtual performance recorded directly in Hauptwerk. The sequencer is NoteWorthy Composer 2. The organ is an import from the HW 1 Litomysl sample set renamed as the "Etoile" Organ. The sample set, customized definition, and Hauptwerk setup belong to Colossus.
Thiman's work is a simple and lovely reflective piece based on one of Bach's borrowed melodies.
