摘要： A musical tone parameter generating method and a musical tone generating device of this invention feature that when data inputted by a player is inputted into a neural network as input pattern, the neural network infers the parameters necessary to specify a musical tone wave form to be formed. This makes it possible to get parameters other than those stored in a memory by inferring, which increases variation of the musical tone to be generated.
摘要翻译：本发明的乐音参数产生方法和乐音产生装置的特征在于，当将由玩家输入的数据输入神经网络作为输入模式时，神经网络推断出必须指定要形成的乐音波形的参数。这使得通过推断获得存储在存储器中的参数以外的参数成为可能，这增加了要生成的乐音的变化。

摘要： 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.

摘要： Automatic performance data of plural channels are read from a memory, these data are interpolated by interpolation data and an automatic performance tone is generated on the basis of the interpolated automatic performance data. The interpolation data can be variably set in accordance with an operation by a player whereby the player's feeling can be reflected freely on the automatic performance in real time performance. Change data for changing the automatic performance data may be stored in a memory and this change data may be selected freely by a selective operation by the player. The selected change data may be variably controlled by an operation by the player. Plural types of change data patterns corresponding to one phrase may be stored and a sequence combination of these change data patterns may be freely set and changed. By these arrangements, an automatic performance which is rich in expression of feeling as in a live performance can be realized.
摘要翻译：从存储器读取多个通道的自动性能数据，这些数据通过插值数据进行内插，并且基于内插的自动演奏数据生成自动演奏音。可以根据玩家的操作来可变地设置插值数据，由此玩家的感觉可以在实时性能的自动演奏上自由地反映。用于改变自动演奏数据的更改数据可以存储在存储器中，并且该改变数据可以由玩家的选择性操作自由选择。所选择的改变数据可以由玩家的操作来可变地控制。可以存储对应于一个短语的多种类型的改变数据模式，并且可以自由地设置和改变这些改变数据模式的序列组合。通过这些布置，可以实现在现场表演中丰富的感觉表现的自动表演。
