Abstract

The computer-implemented system stores user performance data representing multiple parts. The system also stores style data representing various different musical accompaniments that are displayed in a style data window. The user selectively copies constituent parts of the style data into a user performance data window, thereby incorporating the copied parts into the performance data. Tone pitches and musical length of the copied parts are automatically modified to suit the chord information and timing represented in the existing performance data. As the user records performance data, the on-screen start switch is displays differently (e.g., different color) to show whether the specific part corresponds to a recording part or a non-recording part.

Claims (18)

1. A performance information edit and playback apparatus comprising:

a first storage for storing style data, wherein the style data include a prescribed accompaniment part representing a predetermined length of accompaniment;

a second storage for storing user's performance data produced by a user, wherein the user's performance data include an accompaniment part and another performing part subjected to simultaneous playback with the accompaniment part;

a mode selector switch for alternatively selecting, in accordance with a user's operation, one of a style data playback mode and user's performance data playback mode; and

a playback device operable to simultaneously play back the prescribed accompaniment part included in the style data and another performing part included in the user's performance data when the mode selector selects the style data playback mode upon starting playback, said playback device operable to simultaneously play back the accompaniment part included in the user's performance data and another performing part included in the user's performance data when the mode selector selects the user's performance data playback mode upon starting playback.

2. A performance information edit and playback apparatus according to claim 1 , wherein both of the accompaniment parts included in the user's performance data and the prescribed accompaniment parts included in the style data commonly share a same tone-generation channel or a same tone color.

3. A performance information edit and playback method comprising the steps of:

storing style data, wherein the style data include a prescribed accompaniment part representing a predetermined length of accompaniment;

storing user's performance data produced by a user including an accompaniment part and another performing part, subjected to simultaneous playback with the accompaniment part;

alternatively selecting in accordance with a user's operation of a mode switch one of a style data playback mode and user's performance data playback mode;

simultaneously playing back the prescribed accompaniment part included in the style data and another performing part included in the user's performance data when in the style data playback mode upon starting playback; and

simultaneously playing back the accompaniment part included in the user's performance data and another performing part included in the user's performance data when in the user's performance data playback mode upon starting playback.

4. A machine-readable medium storing performance data edit and playback programs that cause a computer to perform a method comprising the steps of:

storing style data, wherein the style data include a prescribed accompaniment part representing a predetermined length of accompaniment;

storing user's performance data produced by a user including an accompaniment part and another performing part subjected to simultaneous playback with the accompaniment part;

alternatively selecting in accordance with a user's operation of a mode switch one of a style data playback mode and user's performance data playback mode;

simultaneously playing back the prescribed accompaniment part included in the style data and another performing part included in the user's performance data when in the style data playback mode upon starting playback; and

simultaneously playing back the accompaniment part included in the user's performance data and another performing part included in the user's performance data when in the user's performance data playback mode upon starting playback.
