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.

A parameter control device that controls an increase/decrease in parameter value based on pulses generated in response from an operator, includes a current value storage unit storing a current value of a parameter value in response to the operator, a measurement time setting unit setting a measurement time in which the number of generated pulses is measured from a current value of the parameter value and a maximum value or a minimum value that the parameter value can take, a threshold setting unit respectively setting thresholds of the number of generated pulses to the maximum value side or the minimum value side, a counting unit counting the number of generated pulses of the operator within the measurement time, a comparison unit comparing the counted number of generated pulses and the thresholds, and an output determination unit determining a parameter value to be output from the operator based on the comparison.

When transferring waveform data from a waveform region in a high-capacity flash memory to a waveform buffer in a RAM, first, whether a non-ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the allocated non-ring buffer region. If such a non-ring buffer region cannot be allocated, then whether a ring buffer region that can receive the waveform data can be allocated in the RAM is determined, and if so, the waveform data is transferred to the ring-buffer region in a ring buffer operational manner.

In the present invention, a user is capable of choosing manually or automatically a point on a chosen keyboard where a division will occur. For musical/artistic reasons, this point must regularly change. To accommodate this need, the user can store that location in an existing preset/restore system and recall it upon demand with other settings.

A musical sound generation device including a first memory having a plurality of waveform data, a second memory which stores waveform data read out from the first memory, and a control processor which controls such that, when a sound emission instruction is provided and specified waveform data is in the second memory, the waveform data is read out by the sound source processor, or controls such that, when a sound emission instruction is provided and specified waveform data is not in the second memory, the specified waveform data is transferred from the first memory to the second memory and read out by the sound source processor, in which the control processor controls such that waveform data satisfying a set condition is not subjected to a waveform data change by the transfer and waveform data not satisfying the set condition is subjected to the waveform data change by the transfer.

A musical sound generation device including a first memory having a plurality of storage areas where waveform data is read out and stored, a waveform generator which functions as a plurality of waveform generating sections each of which generates a waveform for emitting a sound by reading out waveform data from a selected storage area of the first memory; and a control processor which determines, when an instruction for sound emission is provided, a combination of a waveform generating section and a storage area to be used for the instructed sound emission, based on a status of reading waveform data from each storage area by each waveform generating section.

An electronic musical instrument includes: a plurality of performance elements that specify pitch data; a sound source that produces musical sounds; and a processor configured to perform the following: when a user performance of the plurality of performance elements satisfies a prescribed condition, instructing the sound source to produce a sound of a first timbre and a sound of a second timbre, both corresponding to a pitch data specified by the user performance; and when the user performance of the plurality of performance elements does not satisfy the prescribed condition, instructing the sound source to produce the sound of the first timbre corresponding to the pitch data specified by the user performance and not instructing the sound source to produce the sound of the second timbre.

Some timbres in the timbre combinations are selected and memorized according to the above timbre selection means corresponding to the timbre groups that the selected timbres belong to. The timbre combinations are classified and memorized according to the timbre groups. Thus it is made easy to search a timbre combination. When the store button 27 is turned on (step 61), it is identified which zone is appointed by the zone select buttons 24 being turned on placed on the switch table (step 63) and tone number data in the zone in the setup timbre register 42 are read out (step 64). At the top address of the vacant area in the setup area of the timbre group area on the timbre table 61 corresponding to the selected tone number data, tone number data, loudness data and setup range data of all the zones of the setup timbre register 42 (step 65).
