Abstract
An electronic musical instrument, which enables a player easily to select by operating a switch any of a plural number of tone colors from a large number of tone colors originally preset in the musical instrument in a form of tone color data stored in a memory unit, to thereby more easily carry out a performance within a broadened range of performance techniques.
Claims24
An electronic musical instrument comprising:
- first memory means having a large plurality of tone color memories for storing tone color information in the form of binary codes, said tone color information comprising a plurality of data elements for determining various tone colors, the respective data elements being stored in the respective tone color memories;
- second memory means for reading said tone color information from at least one of said tone color memories of said first memory means and for storing said tone color information;
- selecting means coupled to said second memory means for selecting one data element for determining a desired tone color from said tone color information stored in said second memory means;
- and
- means coupled to said second memory means for producing a musical tone of the tone color determined by the tone color information thus selected.

An electronic musical instrument comprising:
- first memory means having a large plurality of tone color memories for storing tone color information in the form of binary codes, said tone color memories being allotted respective code numbers, said tone color information comprising a plurality of data elements for determining various tone colors;
- second memory means for reading some of the code numbers allotted to said tone color memories of said first memory means and for storing the code numbers thus read out;
- selecting means for selecting one of the code numbers stored in said second memory means;
- and
- means for producing a musical tone of the tone color determined by the tone color information which is stored in the tone color memory to which the code number thus selected is allotted.

An electronic musical instrument comprising:
- first memory means having a large plurality of memory sections for storing tone color information in the form of binary codes, said tone color information comprising a plurality of data elements for determining various tone colors;
- second memory means having far fewer memory sections than said first memory means;
- selecting means for reading the tone color information from at least one of the memory sections of said first memory means and for writing said read-out tone color information into one of the memory sections of said second memory means, for selecting the tone color information stored in said second memory means;
- and
- means coupled to said second memory means for producing a musical tone of the tone color determined by the tone color information thus selected.
