BACKGROUND OF THE INVENTION
This is a continuation of copending application Ser. No. 07/321,227 filed on Mar. 8, 1989, now abandoned.
1. Field of the Invention
The present invention relates to an automatic performance apparatus of an electronic musical instrument capable of activating and deactivating automatic performance for each musical part such as melody tone, accompaniment tone, or rhythm tone.
2. Prior Art
A conventional performance apparatus is disclosed in Japanese Patent Application Laid-Open Publication No. 60-163094. This conventional apparatus provides a memory, a reading control circuit, and an on-off control switch in each musical part, so that each on-off control switch controls the automatic performance of a separate musical part.
The above conventional apparatus reads out musical tone data stored in memory based on a common address counter, in which the memory is arranged for each musical part. Hence, the on-off control switch of the apparatus can control the musical tone data for either outputting or not, but the reading of the musical tone data stored in the memory progresses even though the reading of the musical tone data is stopped. Problems may arise, for example, because the conventional apparatus cannot start the performance at the beginning of the second musical part after a certain time delay from the first musical part.
It is accordingly an object of the present invention to provide an automatic performance apparatus of an electronic musical instrument capable of automatically activating and deactivating automatic performance based on one musical part in accordance with the other musical part, the performance of which is already in progress.
It is another object of the present invention to provide an auto-performance apparatus of an electronic musical instrument capable of beginning and ending the automatic performance of each musical part in accordance with selective timings.
In a first aspect of the present invention, there is provided an automatic performance apparatus comprising: first automatic performance means having first performance data memory and first reading means, wherein said first reading means reads out performance data stored in said first performance data memory; second automatic performance means having second performance data memory and second reading means, wherein said second reading means reads out performance data stored in said second performance data memory; whereby an instruction signal for reading out performance data stored in said first performance data memory, said instruction signal instructs said second reading means to start and stop reading performance data stored in said second performance data memory.
In a second aspect of the present invention, there is provided an automatic performance apparatus comprising: first automatic performance means having first performance data memory and first reading means, wherein said first reading means reads out performance data stored in said first performance data memory; second automatic performance means having second performance data memory and second reading means, wherein said second reading means reads out performance data stored in said second performance data memory; selection means for selecting at least either said first automatic performance means or said second automatic performance means in accordance with the state of an instruction signal.
