Abstract
The disclosure provides an automatic performance apparatus, an automatic performance method, and a non-transitory computer readable medium. Notes to be sounded are stored in chronological order for each beat position which is a sound generation timing in a performance pattern. A probability of generating sound at the beat position is stored for each beat position in a sound generation probability pattern. According to the probability stored in the sound generation probability pattern, it is determined whether to generate sound or not for each beat position of the performance pattern.
Claims20
An automatic performance apparatus which automatically performs a performance pattern in which sound generation timings of notes to be sounded are set, the automatic performance apparatus comprising:
- a sound generation probability pattern acquisition part which acquires a sound generation probability pattern in which a probability of sounding a note is set for each sound generation timing of the performance pattern;
- and
- an automatic performance part which performs an automatic performance by determining whether to sound the note for each sound generation timing of the performance pattern based on the probability of each sound generation timing set in the sound generation probability pattern acquired by the sound generation probability pattern acquisition part.
An automatic performance method comprising:
- a sound generation probability pattern acquisition step of acquiring a sound generation probability pattern in which a probability of sounding a note is set for each sound generation timing of a performance pattern in which sound generation timings of notes to be sounded are set;
- and
- an automatic performance step of performing an automatic performance by determining whether to sound the note for each sound generation timing of the performance pattern based on the probability of each sound generation timing set in the sound generation probability pattern acquired in the sound generation probability pattern acquisition step.
A non-transitory computer readable medium storing an automatic performance program causing a computer to perform an automatic performance, the automatic performance program causing the computer to execute:
- a sound generation probability pattern acquisition step of acquiring a sound generation probability pattern in which a probability of sounding a note is set for each sound generation timing of a performance pattern in which sound generation timings of notes to be sounded are set;
- and
- an automatic performance step of performing an automatic performance by determining whether to sound the note for each sound generation timing of the performance pattern based on the probability of each sound generation timing set in the sound generation probability pattern acquired in the sound generation probability pattern acquisition step.
