Abstract: An input sequence of musical notes is converted to a melodic contour by detecting note interval changes, e.g., in semitones, between consecutive musical notes in the sequence and mapping the detected note interval changes to corresponding change codes in a defined set of change codes, which have non-uniform step sizes for quantizing note interval changes. Correspondingly, a system, such as a local and/or a remote computer system system (e.g., a web-based melody search server) compares input melodic contours with a database of stored melodic contours to determine matching information, which can be provided to the users that generated the input sequences of musical notes. The system may be configured to search computer networks to identify audio files for representation in the database of stored melodic contours. Further, an embodiment provides for a graphical keyboard for entry of musical note sequences and/or provides for receiving such sequences through a MIDI port.

Abstract: A universal computer event translator, which can be implemented as a computer program for execution on a personal computer, handheld device, or other computer processing platform, provides configurable event translation to map essentially any type of computer input event into essentially any other type(s) of computer input event. The program detects occurrences of desired types of input events, which may be generated via a particular input device, a timer, or another program or processing running on the computer, and provides rules-based translation processing of those events. For example, the program can translate mouse events into keyboard events, MIDI or other port events into mouse or keyboard events, or into custom events. One incoming input event can spawn one or more translated input events of one or more types; conversely, different types of incoming input events can be mapped to a single type or multiple types of translated input events.
