When a performance start instruction is issued in this state, first, at time t ₁ , the sequencer controller 130
Before the performance of the first song, the first sequencer 1
For 10, the sound source parameter OP for the first song
1 is output. Thereby, the first sequencer 110 outputs the sound source parameter OP1 for the first music piece. Then, the output sound source parameter OP1 is transferred to the sound source unit 200 by the transmission unit 140 with a header indicating that the output sound source parameter OP1 is output from the first sequencer 110 added. On the other hand, in the sound source unit 200, the sound source parameter OP1 with the header

Immediately before time t ₂ , all of the sound source parameters OP 1 for the first music piece are stored in the parameter bank 231. Further, when the data BCC is supplied, the bank change unit 220 sets the initial state selection unit 2
33 and the effect selecting unit 234 are instructed to select the parameter bank 231 corresponding to the first sequencer 110 indicated by the data BCC.
The sound source parameter OP1 is used for the effect setting. Therefore, when the performance data M1 output from the first sequencer 110 is received by the tone generator unit 200, the generation of the musical tone based on the performance data M1 is performed by the initial setting based on the tone generator parameter OP1, and the generated tone is generated. Tone for sound source parameter OP1
The effect specified by is provided.

In this way, the performance data M1 is supplied in time series for each performance event, so that a musical tone based on the performance data is generated with the setting based on the tone generator parameter OP1, and an effect based on the tone generator parameter OP1 is added. Then, it is sounded to the outside and a performance of one music is performed.

[0021] Incidentally, such performance data to be chronologically forward for each event, as shown in FIG. 2 (b), time intervals for performance data M1 is not supplied at time t ₂ later there are many. Sequencer control unit 130
It uses such intervals, to a second sequencer 120, the time t ₂ later, and controls to output the sound source parameter OP2 according to the second song. The sound source parameter OP2 thus output is transmitted to the
A header indicating that it has been output from the second sequencer 120 is added thereto, multiplexed with the performance data M1 output by the first sequencer 110, and transferred to the tone generator unit 200. That is, at time t ₂
Thereafter, during the performance of the first song, the performance data M
The sound source parameter OP2 for the second music piece is also transferred to the sound source unit 200 during the interval between the transfer of the first music piece. Then, the sound source parameter O transferred to the sound source unit 200

By the way, immediately before time t ₃ , all of the sound source parameters OP 2 for the second music are stored in the parameter bank 232. When the data BCC is supplied at time t ₃ , the bank changing unit 220
The second sequencer 120 indicated by the data BCC is provided to the initial state selection unit 233 and the effect selection unit 234.
, The tone generator OP 241 is used for the initial setting of the tone generator 241 and the effect setting of the effect imparting unit 243. Therefore, when the performance data M2 output from the second sequencer 120 is supplied to the tone generator unit 200, the generation of the musical tone based on the performance data M2 is performed by the initial setting based on the tone generator parameter OP2, and the generated tone is generated. The effect defined by the sound source parameter OP2 is given to the musical tone.

After time t ₃ , the sequencer control unit 1
The control unit 30 controls the second sequencer 120 to supply the performance data M2 for the second song, but controls the first sequencer 110 to perform the performance data M2.
At time intervals when no 2 is supplied, control is performed so as to output the sound source parameter OP1 for the third tune.
The sound source parameters are all stored in the parameter bank 231 corresponding to the first sequencer by the above-described process until the performance of the second tune is completed. Then, when the performance based on the performance data M2 for the second tune ends, the sequencer control unit 130 returns to time t ₄
, The first sequencer 110 is controlled to supply the performance data M1 for the third tune in chronological order, while the second sequencer 120 is not supplied with the performance data M1 at any time interval. Then, the sound source parameter OP4 for the fourth music piece is controlled to be output. Similarly, the sequencer control unit 130 sets the (n-
1) When the performance based on the performance data of the tune is completed, one of the sequencers is controlled to supply the performance data of the n-th tune in time series, while the other sequencer is controlled to perform the performance data. At time intervals when data is not supplied, control is performed so as to output sound source parameters for the (n + 1) th music piece.

As described above, according to the music performance apparatus of the present embodiment, if n is an integer of 1 or more, during the transfer of the performance data for the n-th song, the next (n +
1) The tone generator parameters of the music are also transferred and stored, while the initial setting of the tone based on the nth performance data and the setting of the effect to be applied to the generated tone are previously stored in the parameter bank corresponding to the header of the performance data. This is performed based on the stored sound source parameters. Therefore, it is not necessary to transfer the sound source parameters for the (n + 1) th tune after playing the nth tune and before playing the (n + 1) th tune. Therefore,
It is possible to shorten the blank between the n-th song and the (n + 1) -th song.

Further, in the music performance apparatus according to the present embodiment, it is possible to perform fade-in and fade-out without increasing the number of sounding channels of the tone generator 241 in the following manner. That is, the sequencer control unit 1

0 is controlled respectively. Thereby, the initial setting of the musical tone based on the performance data relating to the n-th music and the setting of the effect to be given to the generated musical tone are performed by sound source parameters stored in advance in the parameter bank corresponding to the performance data, that is, The initial setting of the tone based on the performance data of the (n + 1) -th song and the setting of the effect to be given to the generated tone are performed based on the sound source parameters of the n-th song. This is performed based on the sound source parameters for the tune. Therefore, it is possible to make the n-th song fade-out and the (n + 1) -th song fade-in.

The functional configuration of the data transfer unit 100 and the tone generator unit 200 in the above-described embodiment can be constructed by a general personal computer equipped with a sound board capable of generating sound based on MIDI data. That is, a plurality of files in the MIDI format can be provided on an HD or the like, and a desired file can be designated from these files along with the order of performance, and the data can be transferred as described above. Also, in a so-called communication karaoke in which data relating to the music to be played is supplied via a communication line, the data is transferred to the sound source on the terminal side as described above, thereby shortening the interval between the music to be played. It is possible to plan.
