Electronic musical instrument with programmable synthesizing function

摘要

The electronic musical instrument has synthesis means operative according to given tone control parameters for effecting a musical tone synthesis to generate a musical tone. Register means is provided for registering first data of a lower class and second data of an upper class in hierarchical data structure so as to constitute the tone control parameters. The first data is effective, at least, to define a timbre of a musical tone to be generated. The second data designates a plurality of the first data, effective to control the musical tone synthesis according to different timbres which are defined by the plurality of the first data. Edit means is provided for revising selectively the registered first data. Display means is provided for selectively indicating the second data which is associated to the first data to be revised in order for management of the hierarchical data structure.
