Fomus

(list-fomus-instrgroups &key :format format)

Lists FOMUS instrument ordering/grouping data, merging/replacing FOMUS's own defaults with the contents of the INSTR-GROUPS setting. If the FORMAT argument is T (the default), FOMUS formats the results by listing the instruments for each grouping in a vertical score-order arrangement surrounded by [], {} and || brackets, denoting whether instruments are grouped by brackets, curly braces or barlines only. If FORMAT is NIL, FOMUS outputs the data as nested lists of symbols (see the INSTR-GROUPS setting for details).
