Abstract: A musical instrument instruction system utilizes a CD-ROM electronic storage medium to store audio and video musical instrument instructional materials. Instructional materials are accessed utilizing a computer which provides an interactive system in which animation, voice, music, video and imagery are integrated in essentially real time and under complete control of the music student. The system permits the student to access the instructional materials in a variety of ways, and control the parameters governing the presentation of the instructional materials, including control of the tempo of the music and whether or not displays of the manner of playing the musical instrument will be shown with a displayed notation or tablature relating to the selected musical piece. A mixer is provided for combining musical output of the practice instrument with musical output generated by the computer corresponding to the selected musical piece.

Abstract: In an automated system for learning to play a musical instrument, music data and tone control data for a musical composition of an exemplary musical instrument is stored in machine readable form. An audio signal generated by a musical instrument being played, corresponding to the exemplary musical instrument, is inputted through a musical effects apparatus wherein the musical tone of the musical instrument being played is mixed with the stored music data. The musical effects apparatus is utilized, under digital control, to match the musical tone of the musical instrument being played with that of the exemplary musical instrument. More particularly, the music data and tone control data of the musical composition are stored on a conventional CD-ROM. The tone control data is utilized to create control parameters which can be used to control one or more electronic effects devices in an automated fashion.

Abstract: A method and apparatus are disclosed for providing color matching between populations of color output devices, such as color monitors and color printers. The method includes the steps of establishing a set of aim curves for each population of color output devices based on measured color luminance values of each member of the population, and constructing first and second sets of color correction transforms for each of the color output devices based on the aim curves and the measured color luminance values. The correction transforms are then provided to the device driver of each of the color output devices. The method and apparatus can transform the color outputs of a population of color output devices from a device-dependent color gamut to a population dependent color gamut.
