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： A musical tone synthesizing apparatus includes an excitation circuit, a resonator circuit, and a resampler. The excitation circuit generates an excitation signal, through a non-linear transformation, in response to an input signal supplied thereto. The resonator circuit resonates the excitation signal supplied thereto. The signal processing in the excitation circuit is executed in synchronization with a high sampling frequency N*Fs. The resampler converts the excitation signal of the high sampling frequency N*Fs into that of a normal frequency Fs. The excitation signal from the resampler, which has the normal sampling frequency Fs, is supplied to the resonator circuit. Accordingly, the resonator circuit can perform its operation at the normal sampling frequency Fs. The high-speed operation of the excitation circuit prevents the abnormal oscillation and the generation of an aliasing noise in the musical tone synthesizing apparatus.

摘要： In the case where an automatic reading file composed of plural kinds of detailed parameters stored in a transportable storage device whose attachment is detected has been already read in an apparatus, it is determined whether update, to a currently-read automatic reading file, of an automatic reading file stored in a storage section is carried out or not in accordance with a user's instruction, and is controlled so as to carry out a process. Namely, in the case where an automatic reading file has not been read yet, the automatic reading file stored in the storage section is updated to the currently-read automatic reading file without any condition. On the other hand, if an automatic reading file has been already read, the automatic reading file stored in the storage section may be edited on the basis of it.

摘要： User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. Digital audio signals processed by a first signal processing circuit are stored into a memory and transmitted to a second signal processing circuit via a cascade-connection. The second signal processing circuit adds the audio signal, processed for each of the steps, to audio signals input via the cascade-connection and writes added signal into the memory.
