摘要： An electronic musical instrument includes: a performance controller; and at least one processor, configured to perform the following: instructing sound generation of a first musical tone in response to a first operation on the performance controller; in response to a second operation on the performance controller during the sound generation of the first musical tone, obtaining a first amplitude value of the first musical tone at a time of the second operation, and obtaining a second amplitude value at which a second musical tone is to be sound-produced in response to the second operation on the performance controller; acquiring a parameter value for determining at least one of pitch, timbre, and volume of the second musical tone based on a ratio of the first amplitude value to the second amplitude value; and instructing sound generation of the second musical tone in accordance with the acquired parameter value.

摘要： 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.

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 delay time counter in a DSP cyclically counts a sampling clock from zero to a delay time sampling count and issues a delay time interrupt to a CPU each time the sampling clock count reaches the delay time sampling count. The CPU measures a time difference between each time the DSP issues the delay time interrupt and each time sequence clock interrupts occur a number of times corresponding to the delay time. Then, in order to reduce this time difference, the CPU increases or decreases a maximum count that is set to the sequence clock counter. Therefore, in the next delay process, the shift between the time by which the automatic performance is advanced by the CPU (which is equal to the delay time) and the timing of the delay process executed by the DSP (which is also equal in length to the delay time) will be corrected.
