Abstract

Performance information of a music performance executed by a user is received, and temporarily stored into a buffer for each given time period. The performance information is recorded into a recording section in response to a recording instruction by the user. Second performance information having a definite time period is reproduced repeatedly, and the user ad-libs a desired musical performance while listening to the repeatedly reproduced tones of the second performance information. The given time period is set to coincide with the definite time period of the second performance information. Temporarily-stored performance information for the given time period is recorded in one of a plurality of recording tracks. In response to a plurality of user's recording instructions, a plurality of different segments of performance information for the given time period are recorded into respective ones of the recording tracks, and these different segments are reproduced repeatedly in synchronized fashion.

First claim

The invention claimed is:

1. A performance information processing device comprising:
a performance information reception section that receives live first performance information of a music performance executed by a user;
a reproduction section that repeatedly reproduces recorded second performance information having a given time period;
a buffer section that temporarily and continuously stores a segment of the live first performance information;
a recording instruction section that receives a recording instruction given by the user for recording a segment, having a time length same as the given time period of the recorded second performance information, of the temporarily stored segment of the live first performance information; and
a control section configured to instantaneously record, in response to the recording instruction, the entire segment, having the time length same as the given time period, of the temporarily-stored segment of the live first performance information that was already completed, into a recording section as recorded third performance information,
wherein the reproduction section further repeatedly reproduces the recorded third performance information in synchronism with repeated reproduction of the recorded second performance information that was recorded before the recorded third performance information.

2. The performance information processing device as claimed in claim 1 , wherein the control section records, into the recording section, the entire segment of the temporarily-stored segment of the live first performance information of a latest time period, which is equivalent to the given time period.

3. The performance information processing device as claimed in claim 1 , further comprising:
a recording deletion instructing section that receives a recording deletion instruction given by the user,
wherein the control section deletes, in response to the recording deletion instruction, the third performance information from the recording section.

4. The performance information processing device as claimed in claim 3 , wherein:
the recording section has a plurality of recording tracks,
the control section is configured to record, in response to the recording instruction, the third performance information, which has the time length same as the given time period, into any one of the plurality of recording tracks, so that, in response to a plurality of recording instructions, different segments of the temporarily-stored segment of the live first performance information, each having the time length same as the given time period, are each recorded into one of the plurality of recording tracks, and
the reproducing section reproduces the different segments of the temporarily-stored segment of the live first performance information recorded into the plurality of recording tracks repeatedly in synchronized relation to each other.

5. A performance information processing method comprising the steps of:
receiving live first performance information of a music performance executed by a user;
repeatedly reproducing recorded second performance information having a given time period;
temporarily and continuously storing, in a buffer section, a segment of the live first performance information;
receiving a recording instruction given by the user for recording a segment, having a time length same as the given time period of the recorded second performance information, of the temporarily stored segment of the live first performance information;
instantaneously recording, in response to the recording instruction, the entire segment, having the time length same as the given time period, of the temporarily-stored segment of the live first performance information that was already completed, into a recording section as recorded third performance information; and
repeatedly reproducing the recorded third performance information in synchronism with repeated reproduction of the recorded second performance information that was recorded before the recorded third performance information.

6. A non-transitory computable-readable storage medium containing instructions executable by a processor to perform a performance information processing method comprising:
receiving live first performance information of a music performance executed by a user;
repeatedly reproducing recorded second performance information having a given time period;
temporarily and continuously storing, in a buffer section, a segment of the live first performance information;
receiving a recording instruction given by the user for recording a segment, having a time length same as the given time period of the recorded second performance information, of the temporarily stored segment of the live first performance information;
instantaneously recording, in response to the recording instruction, the entire segment, having the time length same as the given time period, of the temporarily-stored segment of the live first performance information that was already completed, into a recording section as recorded third performance information; and
repeatedly reproducing the recorded third performance information in synchronism with repeated reproduction of the recorded second performance information that was recorded before the recorded third performance information.
