Abstract
Abstract Combinations of operation data such as timbre data, effect data, and the like, which are designated for a musical performance, are stored in a memory. The operation data is read out from the memory, and a musical tone signal corresponding to the readout operation data is generated and a musical tone is produced. Operation data is an operation mode can be transferred to, e.g., a normal mode, and a musical tone signal corresponding to the readout operation data can be generated and a musical tone can be produced in the normal mode. Operation data set in the normal mode can also be transferred to the operation mode. Part of the combined operation data can be easily updated.

Claim 1
Independent Claim
325 words
An electronic musical instrument which is operable in a plurality of modes including an operation mode, comprising: operation data storage means for storing a plurality of operation data items each including a combination of different timbre data and/or effect data; operation mode selecting means for selecting an operation mode of the instrument for generating a musical tone by using one of said operation data items stored in said operation data storage means; canceling means for canceling said operation mode selected by said operation mode selecting means and for selecting a mode other than said selected operation mode; operator means operable by an operator of the instrument for designating one of said plurality of operation data items stored in said operation data storage means when the instrument is in said operation mode and for designating one of the timbre data and effect data allotted to said operator means when the instrument is in a mode other than said operation mode; operation data read-out means for reading out from said operation data storage means the operation data item designated by said operator means when the instrument is in said operation mode; tone generating means for generating a musical tone by using the operation data item read out by said operation data read-out means; holding means for holding the operation data item read out while the instrument was in said operation mode when the mode other than said operation mode is selected by said canceling means when the instrument is in said operation mode; updating means for updating the operation data item held in said holding means by changing timbre data and/or effect data included in the operation data item held in said holding means to designated timbre data or effect data by said operation means when the instrument is in the mode other than said operation mode; and writing means for writing the updated operation data item in said holding means into said operation data storage means.
Claim 2
Dependent Claim
325 words
An electronic musical instrument which is operable in a plurality of modes including an operation mode, comprising: operation data storage means for storing a plurality of operation data items each including a combination of different timbre data and/or effect data; operation mode selecting means for selecting an operation mode of the instrument for generating a musical tone by using one of said operation data items stored in said operation data storage means; canceling means for canceling said operation mode selected by said operation mode selecting means and for selecting a mode other than said selected operation mode; operator means operable by an operator of the instrument for designating one of said plurality of operation data items stored in said operation data storage means when the instrument is in said operation mode and for designating one of the timbre data and effect data allotted to said operator means when the instrument is in a mode other than said operation mode; operation data read-out means for reading out from said operation data storage means the operation data item designated by said operator means when the instrument is in said operation mode; tone generating means for generating a musical tone by using the operation data item read out by said operation data read-out means; holding means for holding the operation data item read out while the instrument was in said operation mode when the mode other than said operation mode is selected by said canceling means when the instrument is in said operation mode; updating means for updating the operation data item held in said holding means by changing timbre data and/or effect data included in the operation data item held in said holding means to designated timbre data or effect data by said operation means when the instrument is in the mode other than said operation mode; and writing means for writing the updated operation data item in said holding means into said operation data storage means.
