Tone visualizing apparatus

A tone visualizing apparatus for visualizing an inputted audio signal to thereby display an image corresponding to this audio signal includes at least a detector, image display (such as a CRT display unit) and display controller. The detector detects characteristics of the audio signal such as envelope, chord, spectrum signal components, number of zero-cross points and energy of the audio signal. The image display displays an image based on given image information which can be generated from a video tape recorder (VTR), a video disk unit or an image memory constituted by a semiconductor memory. The display controller controls the image display so that a display parameter of the image will be controlled based on the detected characteristics of the audio signal. For example, the display parameter can be set as size, brightness or colors of the image. Thus, the image is controlled so that the impression of the image will be matched with that of the audio tone.

Musical tone visualizing apparatus which displays an image of an animated object in accordance with a musical performance

A musical tone visualizing apparatus includes at least an image memory for storing plural images relating to players and/or musical instruments of an orchestra, a display unit for displaying the images on a display screen thereof and a display control circuit for controlling the display unit so that displayed images can be varied in response to an inputted musical tone signal or inputted performance information outputted from an electronic musical instrument, for example. Hence, it is possible to move the players and musical instruments in response to performance of the electronic musical instrument, and it is also possible to selectively enlarge one display image of the player and musical instrument whose tone volume is the largest. Thus, the displayed images can be automatically varied in response to the performance of the electronic musical instrument.

Electronic musical instrument with automatic control of melody tone in accordance with musical style as well as tone color

An electronic musical instrument is provided with tone color specifying switch, musical style specifying switch and device for deciding the joint of melody tones based on the tone color and musical style specified by these switches. A new-timing melody tone is decided to be jointed with a preceding timing melody tone, based on the specified tone color and musical style, in the state of melody tone joint, for example legato state or nonlegato state, during the preceding timing melody tone is being generated.
