Claims (1)

[Claims for Utility Model Registration] 1. A storage means for storing sequence data consisting of at least pitch information that defines the pitch of a musical tone and relative time information that defines the sounding time and muting time of the musical tone; An automatic performance device comprising: a reading unit that reads the sequence data and sequentially reads the pitch information at predetermined time intervals defined by the relative time information; an operator; and an operation of the operator. a first setting means for setting a first playback address number currently being read by the reading means and first time elapsed information corresponding to the current elapsed time; After the reproduction address number and the first time elapsed information are set by the first setting means, the second reproduction address number currently being read by the readout means and the current time elapsed information are set by the operation of the operator. and second setting means for setting second time elapsed information corresponding to the elapse of time, and the reading means has a second setting means for setting a first reproduction address number set by the first setting means and a second elapsed time information corresponding to the elapse of time. The time elapsed information is the playback address and time information at the start of the repeat readout process, and the second playback address number set by the second setting means and the second time elapsed information are used as the playback address and time information at the time of repeating the repeat readout process. An automatic performance device characterized by having playback address and time information. 2. The automatic performance device according to claim 1,
An automatic performance device characterized in that the operator for setting each data in the first setting means and the second setting means is the same. 3. The automatic performance device according to claim 1,
An automatic performance device characterized in that a plurality of said operators for setting each data in said first setting means and said second setting means are provided corresponding to each setting means, respectively. 4. A storage means for storing sequence data consisting of at least pitch information that defines the pitch of a musical tone and relative time information that defines a sound generation time and a mute time of a musical tone; An automatic performance apparatus comprising: a readout means for sequentially reading out the pitch information at predetermined time intervals defined by time information; a first setting means for setting a first playback address number and first time elapsed information corresponding to the current elapsed time; After the time elapsed information is set by the first setting means, the second reproduction address number currently being read by the readout means and the second reproduction address number corresponding to the current elapsed time are set by the operation of the operator. and a second setting means for setting time elapsed information, and the reading means reads the currently read playback address number and the second playback address number set by the second setting means at any time. and after the comparison results match and the time based on the second time elapsed information has elapsed, start repeating the first playback address number and the first time elapsed information set by the first setting means. An automatic performance device characterized by having a playback address and time information. 5. The automatic performance device according to claim 4,
The reading means includes a comparison means for comparing the time information at the reproduction address and the second time elapsed information after the currently read reproduction address number and the second reproduction address number match. However, when it is determined that there is no match based on the comparison result of the comparison means, subtracting the second time elapsed information from the time information at the reproduction address,
This result is set as the current time elapsed information, and the first playback address number and the first time elapsed information set by the first setting means are repeated after the time based on the second time elapsed information has elapsed. An automatic performance device characterized in that the playback address and time information are set at the time of start.
