Provided is an electronic musical instrument. The electrical musical instrument is configured to generate an internal acoustic signal; generate a sound generation instruction signal; output the sound generation instruction signal to an external sound source configured to generate an external acoustic signal; switch a first state in which the external acoustic signal is generated by the external sound source in response to the sound generation instruction signal, to a second state in which the internal acoustic signal is generated in response to the sound generation instruction signal; and, when the first state is switched to the second state, control the volume of the internal acoustic signal such that the state relating to the volume of sound generation based on the internal acoustic signal approaches the state relating to the volume of sound generation based on the external acoustic signal.

A sound control device includes a selector, a sound signal generator, a switcher, and a controller. The selector is configured to select, based on a user operation, one piece of setting information among a plurality of pieces of setting information including at least one timbre group and one effect setting group. The sound signal generator is configured to generate a sound signal based on performance information and the selected setting information. The switcher configured to switch between a hold-enabled state and a hold-disabled state based on a user operation. The controller configured to control the sound signal generator to generate the sound signal such that in the hold-enabled state, even if the selection of the setting information is switched by the selector, at least the effect setting is maintained.

A sound control device includes a plurality of setting interfaces. Each of the setting interfaces includes a parameter operator, a communication interface performing control change message transmission and reception, a generation unit generating the control change message, a designation unit designating validity or invalidity of generating respective sound signals for the plurality of setting interfaces, a mode selection unit selecting a control mode of the communication interface, and a control unit. The control unit controls such that, when a first mode is selected, the control change message generated by the generation unit for a setting interface which is designated as valid among the plurality of setting interfaces is not transmitted through the communication interface, and the control change message generated by the generation unit for a setting interface which is designated as invalid among the plurality of setting interfaces is transmitted through the communication interface.

This tone setter comprises a memory for storing a program and a plurality of tone data; and at least one processor configured to utilize the plurality of tone data and set a sound source. In accordance with the program, the at least one processor executes accepting a selection of one or more tones made by an operation of a user; and setting, in at least an electronic musical instrument or a sound source of the tone setter, tone data corresponding to the selected one or more tones such that sound having the selected one or more tones is generatable with the musical instrument.

An electronic musical instrument includes a sound source LSI to generate a musical sound using a RAM that retains waveform data that has been selectively read from a plurality of waveforms stored in a large-capacity flash memory, and smoothly executes transfer of additional waveform data from the flash memory to the RAM when the requisite waveform data is not retained in the RAM during the performance. Performance data is generated by a sequencer, a prescribed delay time is applied to the performance data by an event time generator and an event delay buffer so as to provide for sufficient time for the transfer of the additional waveform if such transfer is needed. A musical sound is generated by an event buffer and a sound source driver on the basis of the delayed performance data.
