US 4,791,847 A · Parameter setting system for electronic musical instrument

Abstract

A parameter setting system for an electronic musical instrument has a predetermined number of panel switches to which desired parameters can be selectively assigned by the player. The system comprises a RAM having a parameter area in which a group of parameters determining characteristics of a tone are stored, the number of parameters being greater than the number of the panel switches. The RAM also has an identification-number area for storing identification numbers of those parameters which are assigned respectively to the panel switches. When a reassignment switch is depressed with an entry switch, the system is brought into a reassignment mode. In this condition, the player selects a desired one of the parameters using up and down switches for changing the identification number and a display unit for displaying the identification number. The player then depresses one of the panel switches to which the selected parameter is to be assigned, whereupon the displayed identification number is stored into the identification-number area of the RAM at a position corresponding to the depressed panel switch.

Dependent claims

A parameter setting system for an electronic musical instrument for setting one or more of plural parameters each for determining a characteristic of a tone which is generated by a tone generating means incorporated in the electronic musical instrument, said parameter setting system comprising:

one or more manually operable members;
first memory means for storing the plural parameters in such an arrangement that each of the stored parameters can be designated by identification data;
data generating means having first manual control means for generating data whose value is determined by a manual operation of said first manual control means;
second memory means having one or more addresses corresponding respectively to said one or more operable members;
writing means responsive to a manual operation of each of said operable members for writing said data generated by said data generating means into a respective one of said addresses of said second memory means, as said identification data;
parameter setting means for bringing each of those of the plural parameters in said first memory means designated by the identification data contained in a corresponding one of said addresses of said second memory means into a desired condition;
tone generating means for generating a tone signal having characteristics determined by said parameters contained in said first memory means;
and
feeding means for feeding the parameters contained in said first memory means to the tone generating means so that the tone generated by the tone generating means has the characteristics determined by said fed parameters.
