摘要： A level meter displaying method which is capable of changing the rate of change in the angle or position of an indicator in at least one particular input signal level range. A scale image obtained according to a function which nonlinearly varies with a signal level of the sound signal is displayed on a display. The signal level of the sound signal is converted into an indicator angle or indicator position of the level meter according to the function. A level image corresponding to the resulting indicator angle or indicator position is displayed on the display. A curve having at least two inflection points each of which is a boundary between a region where a rate of change of the indicator angle or the indicator position to be converted according to the function is larger, and a region where the indicator angle or the indicator position is smaller is generated by the function.

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： 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.
