摘要： In a musical sound synthesizing apparatus, a loop part including at least a delay element is configured to receive an excitation signal in response to a sound generation instruction so as to synthesize a musical sound signal by looping the excitation signal therein. A waveform memory stores first waveform data representing sound which is generated by a natural musical instrument and which contains resonance, the first waveform data containing a plurality of frequency components having various levels. A waveform processing unit removes, from the first waveform data, one or more frequency component having a level that does not reach a predetermined level, to generate second waveform data. The second waveform data generated by the waveform processing unit is input as the excitation signal to the loop part.

摘要： A digital signal processing for, e.g., tone synthesis or tone control is performed by reading a microprogram from a microprogram memory and executing a digital signal processing algorithm according to this microprogram using necessary coefficients. A first coefficient to be used in this digital signal processing is supplied by a coefficient supply section but this first coefficient is not used directly for execution of the algorithm. A second coefficient which is actually used is generated as a result of a predetermined interpolation operation by a coefficient interpolation section using the first coefficient as a target value. The second coefficient which is used for execution of the algorithm, therefore, changes timewise toward the first coefficient. This coefficient interpolation section is provided independently from the microprogram. Accordingly, the coefficient can be timewise changed and a timewise changing digital signal processing can thereby be realized without imposing undue burden on an external processor or the internal microprogram.

摘要： An electronic musical instrument simulating a wind instrument is fundamentally configured by a loop circuit at least containing a linear portion and a non-linear portion. The linear portion simulates a pipe portion of the wind instrument, while the non-linear portion simulates a breath-blowing portion of the wind instrument so as to produce an excitation signal, which is supplied to the linear portion. By an interaction between the linear portion and the non-linear portion which is carried out while a signal circulates through the loop circuit, a sounding characteristic of the wind instrument is simulated. In order to accurately simulate a jet reed instrument (e.g., organ pipe), there are further provided a delay circuit and an edge tone generator. The delay circuit imparts a delay time to the output signal of the linear portion, and then, a delayed signal is supplied to the non-linear portion. The delay time corresponds to a time which is required when an air flow passing through a slit reaches an edge in the jet reed instrument. The edge tone generator generates a noise signal representing an edge tone (or an aeolian tone) which is unique to the jet reed instrument. The noise signal is mixed with the output signal of the non-linear portion, and then, a mixed signal is supplied to the linear portion. Thus, a sound of the jet reed instrument can be accurately simulated by a musical tone signal picked up from the loop circuit.

摘要： A musical tone synthesizing apparatus utilizes digital signal processors (DSPs) to realize synthesis of musical-tone waveforms with regard to a variety of tone colors. The apparatus stores microprograms and tone-color parameters in advance. Herein, the microprograms represent musical-tone-synthesis algorithms each synthesizing musical tones of a specific tone color. The tone-color parameters contain common parameters and selective parameters to provide a compatibility between different systems having different scales in hardware and software. The common parameters are commonly shared by the different systems, while the selective parameters are provided for a selective use of the musical-tone-synthesis algorithms. So, the apparatus responds to a selection of the musical-tone-synthesis algorithms, wherein the apparatus executes the selected musical-tone-synthesis algorithm, using the common parameters and at least one of the selective parameters, to synthesize musical-tone waveforms with regard to a desired tone color. Incidentally, it is possible to provide different algorithms with regard to derivative tone colors which derive from a base tone color.
