Patent ID: 6956160

Claim:
A music apparatus for generating music tones of a plurality of performance parts constituting a music piece based on sequence data representative of the music piece, the music apparatus comprising: a tone generator that has a plurality of tone generating elements for generating therethrough the music tones; an assigning section that assigns the plurality of the tone generating elements to the plurality of the performance parts such that each performance part may involve one or more of tone generating elements; a sequencer that processes the sequence data to sequentially provide parameters for use in the tone generating elements, the parameters including individual parameters used individually in each of the tone generating elements and a common parameter used commonly in two or more tone generating elements which are assigned to one performance part by the assigning section, each individual parameter including identification information identifying the performance part corresponding to the individual parameter; and a register that is divided into a first area for storing the individual parameters provided from the sequencer and a second area for storing the common parameter provided from the sequencer, wherein each of the tone generating elements acquires the individual parameter from the first area of the register, and acquires from the second area of the register the common parameter corresponding to the performance part which is identified by the identification information contained in the acquired individual parameter, such that each tone generating element can use both of the acquired individual parameter and the acquired common parameter for generating the music tone characterized by both of the individual and common parameters.
