    • An arpeggio playing apparatus comprises a musical tone signal generating device including a plurality of arpeggio playing parts, or an automatic music playing device and at least one arpeggio playing part. The arpeggio playing part is capable of playing an automatic arpeggio with an arpeggio pattern at a progression tempo. Under the condition that one of the arpeggio playing parts or the automatic music playing device has started playing an automatic arpeggio or an automatic music performance at the progression tempo which defines a synchronization timing consisting of periodically aligned synchronization grids, when a start instruction for a new arpeggio playing part is received, the new arpeggio playing part starts the operation in synchronism with the defined synchronization timing. If the start instruction comes at a time point within a delay margin, the arpeggio playing is started immediately and the first span of the arpeggio pattern is played in a shortened time length between the start instruction and the first coming synchronization grid. If the start instruction comes at a time point outside the delay margin, the start of the arpeggio playing is suspended until the first coming synchronization grid.

    • An arpeggio playing apparatus comprises an arpeggio pattern storing device, an arpeggio pattern readout device and an arpeggio tone processing device. The arpeggio pattern storing device stores at least one arpeggio pattern pair including a regular version pattern and an accentuated version pattern for automatic arpeggio performances. When there comes a key-on event representing an arpeggio designation and a key-on velocity, the arpeggio pattern readout device reads out, from the arpeggio pattern storing device, the regular version pattern when the detected velocity is less than a predetermined threshold value, and the accentuated version pattern when the detected velocity is not less than the predetermined threshold value. The arpeggio tone processing device automatically plays arpeggio based on the arpeggio designation by the key-on event and according to the arpeggio patterns of the read-out versions.
    • 一种琶音播放装置,包括琶音模式存储装置,琶音模式读出装置和琶音音调处理装置。 琶音图案存储装置存储至少一个琶音图案对,其包括用于自动琶音性能的常规版本图案和加重版本图案。 当出现表示琶音指定和键入速度的按键事件时,琶音模式读出装置在检测到的速度小于预定阈值时从琶音模式存储装置读出常规版本模式, 以及当检测到的速度不小于预定阈值时的突出版本图案。 琶音音调处理设备基于通过按键事件的琶音指定并根据读出版本的琶音模式自动播放琶音。

    • A frequency characteristics control device of a mixer mixes a first audio signal and a second audio signal inputted to the mixer. In the frequency characteristics control device, a characteristics detection section detects a first frequency characteristic of the first audio signal and a second frequency characteristic of the second audio signal. Based on the first and second frequency characteristics, a removal band detection section detects a removal band in which a level of the first audio signal is higher than a level of the second audio signal. A filtering process section performs a filtering process on the second audio signal so as to attenuate a component of the second audio signal in the removal band. A output section mixes the first audio signal inputted to the mixer and the second audio signal on which the filtering process section has performed the filtering process.

    • By a program process, CPU 31 embeds a watermark data into a waveform data stored in wave memory 41a. The program includes a step for detecting a characterizing part (attack part and loop part) of a waveform data that represents a waveform of a musical tone where the characterizing part represents characteristics of the musical tone, and a step for embedding a watermark data into a part of the waveform data excluding the detected characterizing part. Further, CPU 31 can also extract the watermark data by a program process including a step for detecting the characterizing part and a step for extracting the watermark data embedded in a part excluding the detected characterizing part. Thus, from waveform data including a watermark data, natural musical tones can be reproduced without deteriorating the characteristics of the musical tones at the time of reproduction.

    • A tone generator comprises a basic wave memory for storing a first basic wave data of a musical tone signal, a differential wave memory for storing differential wave data between the first basic wave data and a second basic wave data which is different form the first basic wave data, and mixing device for mixing the first basic wave data and the differential wave data. The musical tone signal is produced by using the mixing device which mixes the basic wave data and the differential wave data without using directly stored sampling data memory. Further a multiplier for multiplying said differential wave data by random factors is provided, the random factors being distributed with normalized probability, resulting in that wave data not only varying tone color at random, but also resembling as a whole the basic wave tone color can be obtained.
