Abstract
A computer-implemented reproduction control method includes reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound. The method includes starting reproducing the first sound, continuing the reproduction of a first sound until an end of the first sound in response to receiving a first instruction in a reproduction period of the first sound, stopping the reproduction of the first sound, and after the stopping of the reproduction of the first sound, starting reproducing the second sound in response to receiving a second instruction provided by a user.
Claims14
A computer-implemented reproduction control method of reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound, the method comprising:
- starting reproduction of the first sound;
- continuing the reproduction of the first sound until an end of the first sound;
- in response to receiving a first instruction provided by a user in a reproduction period of the first sound, preventing reproduction of the second sound from a point in time at which the reproduction of the first sound ends until a point in time at which a second instruction provided by the user is received;
- and
- starting the reproduction of the second sound in response to receiving the second instruction provided by the user,
- wherein the first instruction and the second instruction are each generated in accordance with a manipulation of a pedal-type Musical Instrument Digital Interface (MIDI) controller by the user,
- wherein the sound data is performance data representing a sounding period for each sound of the series of sounds to be reproduced, and
- wherein the first sound is reproduced continuously until the end of the first sound, the reproduction period of the first sound being specified by the performance data.

A computer-implemented reproduction control method of reproducing a series of sounds, including first sound and second sound that follows the first sound, of a piece of music represented by sound data, the method comprising:
- estimating a temporal position of part of the piece of music being played by a user in conjunction with reproduction of the series of sounds of the piece of music being reproduced;
- and
- reproducing the series of sounds following playing of the piece of music by the user based on a result of the estimation,
- wherein the reproducing of the series of sounds includes:
- starting reproduction of the first sound;
- continuing the reproduction of the first sound until an end of the first sound;
- in response to receiving a first instruction provided by a user in a reproduction period of the first sound, preventing reproduction of the second sound from a point in time at which the reproduction of the first sound ends until a point in time at which a second instruction provided by the user is received;
- and
- starting the reproduction of the second sound in response to receiving the second instruction provided by the user,
- wherein the first instruction and the second instruction are each generated in accordance with a manipulation of a pedal-type Musical Instrument Digital Interface (MIDI) controller by the user,
- wherein the sound data is performance data representing a sounding period for each sound of the series of sounds to be reproduced, and
- wherein the first sound is reproduced continuously until the end of the first sound, the reproduction period of the first sound being specified by the performance data.
