Abstract

Abstract An electronic musical instrument is disclosed in which the selection of timbre and rhythm contol functions is simplified, and the number of function switches and control panel surface area can be limited, even when the instrument has a large number of available timbre and rhythm control functions. The invention provides an electronic musical instrument employing various types of musical tone control data which are divided into groups. Additionally, the invention provides an input device which includes a plurality of switches, each switch corresponding to one of the above described groups of musical tone control data. The input device is capable of detecting the operation of the above mentioned switches. Additionally provided is a tone control data management device in which flag data is stored to indicate which of the above mentioned groups of musical tone control data have been selected, the flag data being updated any time one of the above mentioned switches corresponding to a group of musical tone control data has been operated. Also, a musical tone control device is provided such that based on the above mentioned flag data, musical tone control data is selected, and based on the selected musical tone control data, musical tone control is effected.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 134 words
An electronic musical instrument comprising: a) memory means for storing musical tone control data representing a plurality of control data groups; b) a plurality of switches, each switch corresponding to one of the plurality of control data groups; c) control means, responsive to a first operation of at least one of the plurality of switches, for reading from the memory means a first of musical tone control data from a control data group corresponding to the operated switch, wherein the control means reads a different set of musical tone control data within the control data group corresponding to the operated switch with each subsequent operation of the at least one switch; and d) musical tone generating means for generating a musical tone signal based the musical tone control data read from the memory means.
Claim 2
Dependent Claim 134 words
An electronic musical instrument comprising: a) memory means for storing musical tone control data representing a plurality of control data groups; b) a plurality of switches, each switch corresponding to one of the plurality of control data groups; c) control means, responsive to a first operation of at least one of the plurality of switches, for reading from the memory means a first of musical tone control data from a control data group corresponding to the operated switch, wherein the control means reads a different set of musical tone control data within the control data group corresponding to the operated switch with each subsequent operation of the at least one switch; and d) musical tone generating means for generating a musical tone signal based the musical tone control data read from the memory means.
Claim 3
Dependent Claim 41 words
An electronic musical instrument according to claim 1, wherein each of the plurality of control data groups corresponds to a predetermined instrument group, and wherein the musical tone control data within a specified control data group represents a plurality of timbres.
Claim 4
Dependent Claim 23 words
An electronic musical instrument according to claim 1, wherein the predetermined instrument group includes at least one of strings, brass, and wood instruments.
Claim 5
Dependent Claim 41 words
An electronic musical instrument according to claim 1, wherein each of the plurality of control data groups corresponds to a predetermined rhythm group, and wherein the musical tone control data within a specified control data group represent a plurality of rhythms.
Claim 6
Dependent Claim 101 words
An electronic musical instrument according to claim 1 further including clock means for determining a time interval between operations of each of the plurality of switches, wherein the control means is responsive to the clock means such that, for first and second consecutive operations of one of the plurality of switches, if the time interval between the first and second operations of the one switch is less than a predetermined amount, the control means reads musical tone control data from the memory means which is different from the musical tone control data read at the first operation of the one switch.
