Abstract
Abstract A musical tone generator according to the present invention can simultaneously write parameter data at a plurality of storage positions of a parameter storage apparatus for storing various parameters, which characterize a musical tone to be generated, by only one write command. According to the present invention, software can be simplified, and a write execution time can be shortened.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A musical tone generator having a parameter transmitting function comprising: a plurality of channel registers each capable of storing a parameter which characterizes a musical tone to be generated; musical tone generating means for generating musical tones based on said parameters having a plurality of tone generation channels, each of which generates said musical tones characterized by the parameter stored in a corresponding one of the channel registers; commanding means for outputting a writing command; and writing means for writing the same parameter into two or more of said channel registers in response to said writing command, whereby the same parameter is written into a plurality of channel registers in response to a single writing command.
Claim 2
Dependent Claim
116 words
A musical tone generator having a parameter transmitting function comprising: a plurality of channel registers each capable of storing a parameter which characterizes a musical tone to be generated; musical tone generating means for generating musical tones based on said parameters having a plurality of tone generation channels, each of which generates said musical tones characterized by the parameter stored in a corresponding one of the channel registers; commanding means for outputting a writing command; and writing means for writing the same parameter into two or more of said channel registers in response to said writing command, whereby the same parameter is written into a plurality of channel registers in response to a single writing command.
Claim 3
Dependent Claim
101 words
A musical tone generator according to claim 1 wherein the writing means can selectively write a parameter into a single channel register, the tone generator further comprising a designating means for designating a single write state or a plural write state, wherein said writing means writes said parameter into a single one of said channel registers in response to said writing command when said designating means designates said single write state, said writing means writes the same parameter into two or more of said channel registers in response to said writing command when said designating means designates said plural write state.
Claim 4
Dependent Claim
27 words
A musical tone generator according to claim 1 further comprising designating means for designating said two or more channel registers into which the same parameter is written.
Claim 5
Dependent Claim
37 words
A musical tone generator according to claim 1 wherein said plurality of storage portions are channel registers which store parameters for tone generation channels respectively, each of which generates a musical tone characterized by the corresponding parameter.
