Abstract: 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.

Abstract: 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.

Abstract: 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.
Abstract translation: CPU将第一按键间距设定为第一目标值; 将紧接在前的按键间距设置为第一起始点; 从第一按键音发出第一按键声音，朝向第一目标值; 将第二按键音调设定为第二目标值; 设置通过将第一和第二按键间距之间的间距差与上述声音的间距相加作为第二起始点而获得的音高; 从第二按键声音向第二目标值发出第二按键音; 将第三个按键音调设置为第三个目标值; 设置通过将第二和第三按键间距之间的间距差与以第二目标值的方式发射的声音的间距相加作为第三起始点而获得的音调; 并且以第三目标值的形式发出第三按键音音调。
