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.

摘要： In a buffer memory are stored messages given to a specific task in order of arrival. Messages of same types may be stored in the buffer memory. In a different order from the order of arrival, a processing section performs task processing on the basis of the messages stored in the buffer memory. If two messages of a same type are present in the buffer memory, one of the messages which has arrived later than the other is processed with priority irrespective of the order of arrival, and the other message which has arrived earlier is deleted from the buffer memory. If there is present in the buffer memory such a message instructing transfer of parameters corresponding to a function that is not currently assigned, this message itself is deleted from the buffer memory as being ineffective, so as to process a next message.

摘要： A reverberation effect imparting system includes plural comb filters, each of which has a signal delay line and a feedback loop for filtering a delayed output signal from the delay line and feeding the filtered signal back to the input side with a variable loop gain. The device further includes a junction section which receives the respective output signals from the delay lines of the plural comb filters. The junction section controls the received signals with respective variable scattering coefficients and sums up the thus-controlled signals, so as to introduce the summed signal into the feedback loop of each of the comb filters. In this manner, reverberation control according to the waveguide theory is performed by the junction section, while the conventional-type reverberation control is performed by the comb filters. Thus, reverberation can be controlled through a combination of the two controls.

摘要： A musical tone synthesizing apparatus comprises a digital signal processor (i.e., DSP), a main memory and a sub memory. The main memory stores main instructions, while the sub memory stores sub instructions. In accordance with the main instructions and the sub instructions, the DSP performs several kinds of arithmetical operations in a time-division manner. Herein, the main instructions embody algorithms representing a sound source which contains a non-linear table. The contents of the non-linear table represents a non-linear characteristic of a musical instrument to be simulated. Values to be stored in the non-linear table are calculated in accordance with a predetermined mathematical computation utilizing a series expansion, a recurrence formula and the like. By rewriting the contents of the non-linear table, a non-linear characteristic to be applied to musical tone signals is altered in real time. Incidentally, the sub instructions are used to perform several kinds of operations such as an operation of rewriting the contents of the non-linear table and/or a low-pass filtering operation.

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.
