Abstract
An electronic musical instrument has a data compatibility with respect to different models of the electronic musical instruments such as the beginner's model and pro model. In order to match the musical tone control data used in one model with the other musical tone control data used in another model, there is provided a conversion table which memorizes a relationship between them. By referring to this conversion table, certain musical tone control data made by one model is converted into the musical tone control data which can be used in another model. Thus, every model can generate musical tones by use of the musical tone control data which are converted suitably for itself. For example, the musical tone control data represents the tone color of the musical tone to be generated.
