Abstract
When a switching operation from a normal pattern to a special pattern is instructed while an automatic accompaniment operation is being executed using normal pattern data, the pattern to be read out is switched from the normal pattern to the special pattern in accordance with the instruction. In this case, when it is instructed to switch the pattern within the instructed bar, only a rhythm part of a plurality of parts is switched from the normal pattern to the special pattern. When it is instructed to switch the pattern at the beginning of the next bar, other parts in addition to the rhythm part are switched from the normal patterns to the special patterns.
Claims17
An automatic accompaniment apparatus comprising:
- storage means for storing normal pattern data comprising a plurality of normal pattern parts including a normal pattern rhythm part, and for storing special pattern data comprising a plurality of special pattern parts including a special pattern rhythm part;
- instruction means for instructing a switching operation from a normal pattern to a special pattern while an automatic accompaniment operation is executed using the normal pattern data;
- and
- switching means for switching a pattern to be read out from the normal pattern to the special pattern in accordance with said instruction, said switching means controlling whether the pattern is switched in an instructed bar or the pattern is switched at the beginning of the next bar, switching only the normal pattern rhythm part to the special pattern rhythm part when the pattern switching operation is to be performed in the instructed bar, and switching at least one other normal pattern part in addition to the normal pattern rhythm part to a special pattern part when the pattern switching operation is to be performed at the beginning of the next bar.
An automatic accompaniment apparatus comprising:
- storage means for storing pattern data comprising a plurality of parts including a rhythm part;
- automatic accompaniment means for performing an automatic accompaniment according to plural parts of the pattern data stored in said storage means;
- instruction means for instructing a switching operation from the current pattern to another pattern while an automatic accompaniment operation is executed using said automatic accompaniment means;
- and
- switching means for switching the current pattern to be automatically performed to another pattern in accordance with the instruction, said switching means switching only the rhythm part of said plurality of parts to another pattern if the instruction is received by said switching means before a predetermined timing in a bar of the current pattern, and switching the rhythm part and at least one additional part if the instruction is received by said switching means from said predetermined time until an end of said bar.
An automatic accompaniment apparatus comprising:
- automatic accompaniment means for selectively performing a plurality of predetermined musical patterns including a first rhythm pattern, a second rhythm pattern, a first other pattern, and a second other pattern;
- a selector for instructing a change of automatic accompaniment from one group of predetermined musical patterns to another group;
- and
- a controller responsive to said selector and coupled to said accompaniment means, separately controlling switching of said first rhythm pattern to said second rhythm pattern and switching of said first other pattern to said second other pattern depending on a timing of the selecting of the musical patterns relative to a bar of said musical patterns being currently performed.
In a musical tone generation system comprising an apparatus for generating tones according to automatic accompaniment patterns, a method of changing automatic accompaniment patterns comprising the steps of:
- generating tones according to a first rhythm pattern and a first other pattern using said automatic accompaniment apparatus;
- detecting an instruction for changing the automatic accompaniment;
- and
- switching from the first rhythm pattern to said second rhythm pattern while maintaining the first other pattern when said instruction is detected before a predetermined timing in a current bar of the first patterns and switching from the first rhythm pattern to said second rhythm pattern and from said first other pattern to said second other pattern at the beginning of the bar following detection of said instruction if said instruction is not detected before said predetermined timing.
