Abstract: The invention relates to a fungus or a mushroom and to a method of producing it wherein the fungus/mushroom has an increased expression level of a polypeptide and/or has a decreased expression level of a polypeptide, wherein the polypeptide comprises an amino acid sequence that has at least 40% amino acid identity or similarity with a sequence selected from SEQ ID NO:1-200 and/or that has at least 50% amino acid identity or similarity with a sequence selected from SEQ ID NO:201-208.

Abstract: Storage section has stored therein music piece data sets of a plurality of music pieces, each of the music piece data sets including respective tone data of a plurality of fragments of the music piece and respective character values indicative of musical characters of the fragments. Each of the fragments of a selected main music piece is selected as a main fragment, and each one, other than the selected main fragment, of a plurality of fragments of two or more music pieces is selected as a sub fragment. A similarity index value indicative of a degree of similarity between the character value of the main fragment and the character value of the specified sub fragment is calculated. For each of the main fragments, a sub fragment presenting a similarity index value that satisfies a predetermined selection condition is selected for processing the tone data of the main music piece.
