摘要： The position of a connecting portion between waveforms can be arbitrarily set when a plurality of waveform data is obtained by changing pitch widths of stored external sound waveform data, when a read rate of the waveform data is increased or decreased and the readout waveform data is synthesized, or when the waveform is changed from one waveform to another waveform. In addition, a plurality of loop reproduction cycles can be arbitrarily set when the waveform data is to be read out. In loop reproduction, two items of waveform data having different phases between the preset start and end addresses can be repeatedly read out and synthesized, and their mixing ratios can be changed as a function of time, thereby performing loop reproduction so as not to abruptly change amplitude values of the waveforms.

摘要： When a plurality of effects are simultaneously applied to an input audio signal, a plurality of effect-algorithms each for applying solely an effect to the input signal are stored in a memory, and a plurality of combination-algorithms or combination-data which represent combinations of the effects and orders in which effects are applied to the input audio signal are stored in the memory. When one of the combination-algorithms or the combination-data is selected, effect-algorithms included in the selected combination-algorithm or combination-data are selectively read out from the memory. A program for applying effects in a predetermined combination and order is written by CPU based on the read out effect-algorithms and combination-algorithm or combination-data. Receiving the program, DSP successively applies effects to the input audio signal in accordance with the program. As a result, the present effector needs less memory capacity than the conventional effector in which a number of programs consisting of combinations of effect-algorithms are previously stored. A multi-effector comprised of a connection of a digital effect adding device and an analog effect adding device, is provided with a memory having a plurality of memory areas for storing audio signals. An input audio signal, an input signal to the analog effect adding device and an output signal of the digital effect adding device are stored in respective memory areas of the memory. Whether either of input signals is supplied to the digital effect adding device or whether the output signal of the digital effect adding device is input to the analog effect adding device or the output signal is output as a final signal are decided by operation of an externally operated switch. In this way, the order in which effects are applied can be altered independently of the connection of the above two effect adding devices.

摘要： A plurality of groups of tone parameters different in kind required for the generation of a musical sound is stored. The tone parameters of the same kind among those tone parameters are modulated with the same sway signal generated at the same time at a desired time or at fixed intervals of time when a key concerned is depressed. The modulated parameters are either restored in the original storage region or directly delivered to a sound source. The resulting musical sound has an acoustically natural comfortable tone quality. Even if musical sounds are generated simultaneously, no sways in the respective tones of the musical sound are canceled.
