Abstract
An electronic musical instrument such as a synthesizer includes a preset memory for storing, as preset data, a plurality of sets of parameters such as tone colors, tone volumes, pitches, special effects, and the like of tones to be generated. A designated parameter value in the preset data is increased/decreased to edit the preset data. When an edit mode is released, the edited preset data is automatically saved in a recall data memory. When a 'comparison' state is set during an edit operation, the preset data which is being edited is saved in the recall data memory, and preset data before editing or another preset data is set as tone generation data. When a 'recall' operation is performed, data in the recall data memory is read out as the latest preset data for tone generation. The edit operation is performed while confirming generated tones by alternately executing the 'comparison' and 'recall' operations.
