ABSTRACT:
An electronic musical instrument utilizing neural nets comprises parameter input device for inputting a parameter and a neural net device for calculating the parameter. The neural net device is in advance learning therefore, any input parameter results in proper output by interpolation. The instrument further comprises a weighting data memory, the weighting data being provided to the neural net device. The output of the neural net device is interpreted by an interpreter using interpretation knowledge stored in a memory, thereby the output of the neural net device being changed to musical values. Further, the musical values are modified by an output modifier using modification knowledge stored in another memory so as to be accepted musically. The weighting data, the interpretation knowledge and the modification knowledge can be selected by use of selectors, thus use of the selectors expands musical variation.
