[0013]
The panel operator 5 includes a style designating operator 51 for selecting a style and a section designating operator 52 for selecting section pattern data, as shown by being surrounded by a one-dot chain line. When a style is selected by the style designating operator 51, each section pattern data of the automatic performance pattern data corresponding to the selected style is assigned to the section designating operator 52. Pattern data is selected.
[0014]
FIG. 1 is a diagram showing a format of automatic performance pattern data and section chain data in the embodiment. The automatic performance pattern data corresponds to the styles according to the genre and style of the music, and stores automatic performance pattern data for a plurality of styles. Each automatic performance pattern data is composed of a style number and section pattern data corresponding to a plurality of sections (sections 1 to N). Further, each section pattern data is composed of track pattern data corresponding to a plurality of tracks (tracks 1 to M).
[0015]
Each track pattern data is composed of timbre data that specifies the timbre of each track, or performance data that is, for example, one or two measures long, and that stores performance event data and generation timing data indicating the generation timing in the order of playback. Has been. These data are stored, for example, in the format of SMF (standard MIDI file). The performance event data is a parameter such as key code, velocity, and gate time, and forms a performance pattern such as melody, bass, chord, rhythm (drum tone corresponds to key code). The rhythm drum tone and the like are assigned to key codes.
[0016]
Each automatic performance pattern data is stored in association with section chain data recorded in the section chain area. The section chain data is obtained by sequentially storing timing data representing section switching timing and section switching data up to end data. The section switching data is data indicating section pattern data in the automatic performance pattern data.
[0017]
3 and 4 are main part flowcharts of the automatic performance processing program executed by the CPU 1, and the processing of each flowchart is executed in accordance with a mode designated by a main routine (not shown). The section chain creation process of FIG. 3 is a process for the user to select section pattern data as desired from the automatic performance pattern data of the style currently selected by the operation of the style designating operator 51. Real-time recording is performed in a loop of steps S1, S2, S4, and S1, and step recording is performed in a loop of steps S1, S3, S4, and S1.
[0018]
At the time of real-time recording, tempo is set and interrupt processing is executed, and the user operates a desired section designating operator 52 in accordance with, for example, a metronome. Thereby, the section pattern data selected by the section switch is sequentially recorded in correspondence with the operation timing. At the time of step recording, section pattern data is designated by the section designation operator 52 and timing is designated by operation of a timing designation operator such as a numeric keypad or an up / down switch, and the designated section pattern data is made to correspond to the timing. Are recorded sequentially. When the end of recording is designated in step S4, end data is recorded and stored in the section chain area in steps S5 and S6.
[0019]
4 performs automatic performance based on the automatic performance pattern data of the style currently selected by the operation of the style designation operator 51. In this embodiment, according to the mode specified in the determination of step S11, automatic performance in manual mode by manual operation of the section designating operator 52 and automatic performance in chain mode by section chain data are performed. Each time the section designating operator 52 is operated in the loop of steps S12 → S13 → S14 → S12, the section pattern data is switched and reproduction is performed. When stop is designated in step S15, the reproduction is stopped in step S21, and the automatic performance in the manual mode is terminated.
[0020]
In the loop of steps S16 → S17 → S18 → S19, the section chain data is read, and if it is the section switching timing, the section pattern data designated by the section switching data is switched to be reproduced. Then, when end data is detected in step S20 and the end timing is reached, reproduction is stopped in step S21, and the automatic performance in the chain mode is terminated.
[0021]
The section pattern data is reproduced in each mode as follows, for example. The start address and end address of the designated section pattern data are held, and the reproduction of the performance data is repeated between the start address and the end address until the section switching is designated. When the switching is designated, the start address and the end address are rewritten, and the section pattern data to be reproduced is switched. Note that the playback switching timing may be the time when playback is performed up to the end address of the previous section pattern data, or the playback may be switched immediately when switching is designated.
[0022]
Note that the pitch (key code) of the track pattern data (other than the rhythm) is created with a pitch based on a predetermined chord such as a C measure, for example. When a chord is designated, the performance data to be reproduced may be pitch-converted so as to correspond to the designated chord, or may be sounded with the stored pitch.
[0023]
One set of automatic performance pattern data corresponds to the style, and the section pattern data switched by the section chain data is of the same style, so that a musical piece having no sense of incongruity according to the style can be obtained.
