Abstract: A correspondence relationship between virtual logical oscillators, including a master oscillator and at least one slave oscillator, provided for each sound production channel generating a musical tone waveform, and a plurality of physical oscillators for actually generating a waveform and which is associated with the logical oscillators, is stored. Then, according to a process for generating the musical tone waveform, the physical oscillator assigned to the logical oscillator of the sound production channel generating the musical tone is dynamically secured or released with reference to the stored correspondence relationship. Therefore, there is no need to synchronize and playback all waveforms that may possibly be used in the additive synthesis, regardless of whether the waveform is sounded, as is required conventionally. As a result, the waveforms can be generated without needlessly wasting the sound production channel.

Abstract: Dynamics value is acquired intermittently at predetermined time periods, and a waveform data set for a sustain tone, corresponding to the acquired dynamics value, is specified from among waveform data sets stored in a memory. To generate a tone waveform while switching to the specified waveform, a waveform switching time is used which is modified suitably in accordance with a dynamics value variation amount from a predetermined time earlier than the current dynamics value acquisition time to the current dynamics value acquisition time.

Abstract: A method of simulating a string using a wave equation relates movement of the string in time to force acting on the string, wherein the force acting on the string simulates a stream of a fluid medium flowing relative to the string. The simulated string is supported between two supports and is aligned at rest in a first direction between the two supports, a first of which allows movement in a second direction orthogonal to the first direction and a second of which does not allow movement. The string is then caused from rest to vibrate in a plane, which includes the first and second directions, by turbulence in the fluid flow causing the stream of fluid medium to exert a pressure on the string in the second direction. Movement of the string out of alignment with the first direction causes the stream of fluid medium flowing in the first direction to exert a force on the string in the second direction.
