Automatic performance apparatus for an electronic musical instrument

An automatic performance apparatus for an electronic musical instrument;

• comprising;
• storage means for storing first automatic performance data for a automatic performance with a normal performance pattern, second automatic performance data for an automatic performance with a climax performance pattern, third automatic performance data for an automatic performance with a performance pattern which ensures a gradual transition from the automatic performance with the normal performance pattern to the automatic performance with the climax performance pattern, and fourth automatic performance data for an automatic performance with a performance pattern which ensures a gradual transition from the automatic performance with the climax performance pattern to the automatic performance with the normal performance pattern;
• readout means for reading out said first to fourth automatic performance data from said storage means;
• tone generating means for generating musical tones based on said first to fourth automatic performance data read out by said readout means;
• single switching means for selecting the automatic performance with the normal performance pattern or the automatic performance with the climax performance pattern when no automatic performance is being performed, and switching between the automatic performance with the normal performance pattern and the automatic performance with the climax performance pattern when the automatic performance with the normal performance pattern or the automatic performance with the climax performance pattern is being performed;
• start-instructing means for giving an instruction to start an automatic performance;
• first control means for, when the instruction is given by said start-instructing means causing said readout means to read out the first automatic performance data with the normal performance pattern or the second automatic performance data with the climax performance pattern in accordance with the selection by said switching means;
• and
• second control means for causing said readout means to stop reading out the first automatic performance data, read out the third automatic performance data and then read out the second automatic performance data when said switching means is operated during an automatic performance with the normal performance pattern, or causing said readout means to stop reading out the second automatic performance data, read out the fourth automatic performance data and then read out the first automatic performance data when said switching means is operated during an automatic performance with the climax performance pattern.
