摘要： An electronic keyboard instrument includes: a keyboard including a plurality of keys; a plurality of switches that are provided for each key and include a first switch and a second switch that are sequentially turned on by pressing of the key; and a processor. The processor instructs that a noise sound corresponding to a selected musical instrument sound be produced in accordance with a prescribed first envelope upon detecting turning on of the first switch by pressing of the key, and instructs that a main musical sound corresponding to the selected musical instrument sound be produced after detecting turning on of the second switch.

摘要： 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.

摘要： 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.

摘要： A CPU sets a first key-press pitch as a first target value; sets the immediately-preceding key-press pitch as a first starting point; emits the first key-press pitch sound therefrom with portamento toward the first target value; sets the second key-press pitch as a second target value; sets a pitch obtained by adding a pitch difference between the first and second key-press pitches to the pitch of the above-described sound as a second starting point; emits the second key-press pitch sound therefrom with portamento toward the second target value; sets the third key-press pitch as a third target value; sets a pitch obtained by adding a pitch difference between the second and third key-press pitches to the pitch of the sound being emitted with portamento toward the second target value as a third starting point; and emits the third key-press pitch sound therefrom with portamento toward the third target value.

摘要： When an instruction is provided for changing a characteristic of a set filter which includes a plurality of partial filters and forms a specified characteristic by combining a plurality of partial filters, a processor performs, as crossfading processing for a first filter and a second filter among the plurality of partial filters, fade-out processing of gradually decreasing a degree of contribution of the first filter to the characteristic and fade-in processing of gradually increasing a degree of contribution of the second filter to the characteristic. As a result, unnaturalness occurring at the time of changing filter characteristics is solved.
