Electronic music display appliance and method for displaying music scores2010-03-26 00:00:00music, and more specifically, to an electronic music display appliance and a method for storing and displaying music scores.
Electronic music display devices have been proposed which can display music scores using input music score files with industry standard file formats. These files formats include notational and image based formats that have been developed forcomposing and publishing music scores on a fixed page size. Image based formats use image data to represent each page of a music score. Well known PNG, TIFF and JPG are representative of image formats. Notational formats use a set of instructions onhow to build each page of a music score. The instructions include descriptions of notation elements and their associated location on a page. Well known NIFF and MusicXML are examples of notational formats. Examples of proprietary formats are thoseused in Finale.RTM. and Sibelius鈩?music composition and publishing programs.
Conventional electronic music display devices use processing methods and file formats that are not well suited for promptly displaying, manipulating, and modifying music scores. Limited capabilities of these devices can prevent practicaloperations, such as sequentially displaying repeated sections of music, resizing a portion of the music score, displaying a single
instrument's part, displaying a single voice and rapidly jumping to an arbitrary measure. Some of the previous devicesrequire the use of a separate computer to convert an original music score data file into another file format used for displaying images of the music score.
SUMMARY OF THE INVENTION
An object of the present invention is an electronic music display appliance (MDA) for display, manipulation, and modification of a music score. The MDA stores music score information in a music object file. The music object file represents themusic score using music data structures that correspond to notation objects in the music score. The music data structures are grouped on a measure by measure basis. A measure based group includes the music data structures corresponding to the notationelements in a measure of music. The measure based grouping facilitates access to measures of the music score for display, manipulation, and modification. The music data structures are processed to form a page image that includes the notation objects ina selected portion of the music score for display. The MDA includes a touch sensitive display for displaying a page image and for receiving user input. The MDA manipulates the music score in response to user input. Manipulations include marking thescore with annotations, resizing the score for display, jumping to a marked measure and transposing a portion of the music score.
An embodiment of a MDA is a light weight appliance having a LCD display with on screen control and command icons. A touch sensitive screen overlays the LCD display for receiving user input. Inputs can be made using one's finger or a stylus. Aninternal processor operates on music data structures in response to input commands. A memory stores one or more music object files. Data interfaces include USB and wireless communication capabilities. In a preferred embodiment a remote computer or afoot switch are connected using a USB interface. Multiple MDA's can communicate via a wireless interface. An audio output gives the user the option of listening to the tempo of a given music score. System errors and audio confirmation of commandinputs can be selected for audio output. A removable storage module can store music object files.
In another aspect of the invention, conventional notation based music score files are downloaded from a remote computer to the MDA. The MDA parses and translates the downloaded music score file into a measure based music object file. In anembodiment the format for a measure based music object file is the Electronic Music Storage Format (EMSF) described herein.
An aspect of the present invention uses a measure based music object format for efficient processing of music scores. A measure based music object format organizes music score data using the measure as the fundamental grouping unit instead ofthe printed page. A measure is a unit of music that contains notation objects for all the parts and voices found in the measure. The measure based music object format of the instant invention is not constrained to matching the page and line breaks andis not limited to a fixed display size or resolution.
The EMSF format groups music score information by general score data, page and measure layout, part, staff, staff grouping, and measure data. Measure hierarchy includes parts, then voices, and lastly objects and their associated modifiers.
In an aspect of the present invention, a score analyzer and page builder form a page image of the music score using music data structures extracted from the input music object file. The music object file includes measure based music datastructures that correspond to the notation objects in the music score. The active data structures are processed to form a page image that includes the notation objects of the portion of the music score that appear on the displayed page. The LCD displayof the device presents the page of music to the user.
In an aspect of the present invention, a touch screen 110 responds to touch inputs to the displayed page by a user's finger or stylus. Modifications to the displayed music score include transposing, annotating, expanding, and marking measures. Navigation inputs allow sequential page turning, jumping to a specified page, measure, or mark. View options include turning different parts on and off, changing...

Description
BACKGROUND OF THE INVENTION
The present invention relates to electronic means for music generation and more particularly has as its object the provision of such
instrument with a sound engine comprising an architecture enabling the application of thousands of stored unitsof music digital data to rapid production of analog speaker-driving forms, utilizing practical solid state circuit means.
The invention is described below with reference to electronic piano usage, but is also usable in a number of other electronic musical
instrument roles to provide, singly or combined, the sounds of a variety of
instrument, elements of human voiceand other sound sources and in analogous
instrument contexts not involving music or voice, but involving comparably varying waveform data.
Multiple Partial (Fourier) Synthesis is a technique well known in engineering practice. Any arbitrary periodic waveform (e.g., musical
instruments' sound) may be reproduced by summing up a series of sine waves of appropriately determinedfrequencies, amplitudes, and relative phases. This technique allows great flexibility, much more so than subtractive synthesis (which starts out with a complex waveform and filters out unwanted spectral content) or wave-table synthesis (which can onlyreproduce whatever is in the table).
It is the object of the present invention to establish effective
instrumentation using Fourier synthesis.
SUMMARY OF THE INVENTION
The musical apparatus of the invention inputs a stream of digital signals which represent a sequence of audio notes to be ultimately produced. The apparatus creates a sequential list of partials and impresses time-varying amplitude envelopes onthem, such that the sequential list completely characterizes the desired audio signal. A multiple partial synthesis, sometimes referred to as a Fourie...
