Abstract
Abstract A plurality of different kinds of rhythm playing pattern data corresponding to each of the different rhythm sounds being used to play specified rhythms is stored in a rhythm pattern memory section (1). When a particular kind of rhythm is being played automatically, one particular kind of rhythm is selectively designated from a plurality of kinds of rhythms by the operation of the rhythm kind selecting unit (21f). Then, a particular kind of rhythm playing pattern data corresponding to the selected particular kind of rhythm is selected from a plurality of kinds of rhythm playing pattern data preset in the rhythm pattern memory section (1) corresponding to each of the rhythm sounds by the operation of the pattern selection section (2,21,21a-21e). According to this arrangement, since a plurality of rhythm playing patterns are preset to each of the rhythm sounds for each different kind of rhythm, an automatic rhythm play using a selected one of a plurality of rhythm playing patterns can be performed for each rhythm sound by the selecting operation of the pattern selection section (2,21,21a-21e), though the same kind of rhythm is automatically played with the same rhythm sound.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
An automatic rhythm playing apparatus comprising: rhythm sound generating means for generating a plurality of different kinds of rhythm sounds; rhythm pattern memory means for storing a plurality of kinds of rhythm playing pattern data corresponding to each of the different rhythm sounds being used to play specified rhythms; pattern selection means for selectively designating one of said rhythm playing pattern data from said plurality of kinds of rhythm playing pattern data corresponding to each of selected different rhythm sounds; tempo setting means for setting a tempo of an automatic rhythm play; reading means for reading out rhythm playing pattern data designated by said pattern selection means according to a tempo set by said tempo setting means; and rhythm playing means for automatically playing a rhythm by driving said rhythm sound generating means according to the rhythm playing pattern data read out by said reading means, to thereby perform a read out rhythm pattern with a given kind of rhythm sound.
Claim 2
Dependent Claim
161 words
An automatic rhythm playing apparatus comprising: rhythm sound generating means for generating a plurality of different kinds of rhythm sounds; rhythm pattern memory means for storing a plurality of kinds of rhythm playing pattern data corresponding to each of the different rhythm sounds being used to play specified rhythms; pattern selection means for selectively designating one of said rhythm playing pattern data from said plurality of kinds of rhythm playing pattern data corresponding to each of selected different rhythm sounds; tempo setting means for setting a tempo of an automatic rhythm play; reading means for reading out rhythm playing pattern data designated by said pattern selection means according to a tempo set by said tempo setting means; and rhythm playing means for automatically playing a rhythm by driving said rhythm sound generating means according to the rhythm playing pattern data read out by said reading means, to thereby perform a read out rhythm pattern with a given kind of rhythm sound.
Claim 3
Dependent Claim
49 words
The apparatus according to claim 1, wherein said rhythm pattern memory means includes a ROM having registers, in which rhythm playing pattern data for each of said rhythm sounds is stored as separate on/off data for each rhythm sound and timing data representing the "on" timing of each rhythm.
Claim 4
Dependent Claim
64 words
The apparatus according to claim 2, wherein said rhythm pattern memory means further includes a RAM having a rhythm generation flag register, in which a flag is set when said on/off data is "on" data, an address pointer register, in which the number of "on" data in said timing data is set, and a sounding source flag register, in which on/off data is set.
Claim 5
Dependent Claim
45 words
The apparatus according to claim 1, wherein said pattern selection means has a plurality of switch levers each provided for each of said plurality of rhythm sounds, each said switch lever having a plurality of setting positions individually corresponding to said respective rhythm playing patterns.
Claim 6
Dependent Claim
16 words
The apparatus according to claim 1, wherein said rhythm playing pattern data includes chord/bass pattern data.
Claim 7
Dependent Claim
191 words
An automatic rhythm playing apparatus comprising: rhythm kind selecting means for selectively designating one particular kind of rhythm from a plurality of kinds of rhythms; rhythm pattern memory means for storing a plurality of kinds of rhythm playing pattern data corresponding to each of different rhythm sounds which may be used to play a particular kind of rhythm selected by said rhythm kind selecting means; pattern selection means for selectively designating one of said rhythm playing pattern data from a plurality of kinds of rhythm playing pattern data stored in said rhythm pattern memory means; rhythm sound generating means for generating a plurality of different rhythm sounds; and control means for reading out a particular kind of rhythm playing pattern data from a plurality of kinds of rhythm playing pattern data stored in said rhythm pattern memory means according to a selection of said pattern selection means corresponding to each of selected rhythm sounds used to play a particular kind of rhythm selected by said rhythm kind selecting means, and for driving said rhythm sound generation means according to said rhythm playing pattern data for controlling generation of predetermined rhythm sounds.
Claim 8
Dependent Claim
191 words
An automatic rhythm playing apparatus comprising: rhythm kind selecting means for selectively designating one particular kind of rhythm from a plurality of kinds of rhythms; rhythm pattern memory means for storing a plurality of kinds of rhythm playing pattern data corresponding to each of different rhythm sounds which may be used to play a particular kind of rhythm selected by said rhythm kind selecting means; pattern selection means for selectively designating one of said rhythm playing pattern data from a plurality of kinds of rhythm playing pattern data stored in said rhythm pattern memory means; rhythm sound generating means for generating a plurality of different rhythm sounds; and control means for reading out a particular kind of rhythm playing pattern data from a plurality of kinds of rhythm playing pattern data stored in said rhythm pattern memory means according to a selection of said pattern selection means corresponding to each of selected rhythm sounds used to play a particular kind of rhythm selected by said rhythm kind selecting means, and for driving said rhythm sound generation means according to said rhythm playing pattern data for controlling generation of predetermined rhythm sounds.
