Abstract: A system for creating and editing documents may include a reference view function which allows a user to quickly and easily refer to data that may not be included in a document. The inventive system may also include a function for saving and restoring view configurations to ensure that valuable ideas may be stored and recalled, and/or a function for tracking of motivic re-use of data.

Abstract: The present invention enables non-musicians to effectively compose music using a computer, and provides them with the means to manipulate musical content in an intuitive fashion without the need for formal musical training. The invention combines a representation of musical knowledge with a representation of musical data in such a way that permits transposition of the data to be constrained to conform to a set of harmonic rules. The user can select pitches to be moved higher or lower, and a system insures that it sounds good (where good is defined to mean "satisfies the conditions of the harmonic rule base").

Abstract: A system suitable for effecting musical morphing in real time. The system comprises a computer comprising a programmable memory for storing a program. The program comprises the steps of selecting a first musical sequence of events; and identifying a family of first musical elements encompassed by said first musical sequence; selecting a second musical sequence of events; identifying a family of second musical elements encompassed by said second musical sequence. For each new event that is to be generated, the program comprises creating at least one paired set comprising one element from each of the first and second musical sequences; associating each paired set to a parameter type in the new event.
