The present invention aims to change contents of an automatic accompaniment in accordance with a pitch range of a key that a user plays. The electronic musical instrument includes operated keys and a processor. The processor acquires the number of operated keys for each pitch range in accordance with the operation of the keyboard and instructs to switch an automatic accompaniment pattern accompaniment sounds to be emitted in accordance with the acquired number of operated keys for each pitch range.

Electronic musical instrument, accompaniment sound instruction method and accompaniment sound automatic generation device

An electronic musical instrument having an accompaniment function which detects the sound volume of inputted melody sounds for each sound range, and controls the sound volume of accompaniment sounds for each sound range in accordance with the detected sound volume of the melody sounds for each sound range.

A pneumatic tire according to the present invention includes bead units and a carcass layer at least. The bead units includes an inside bead core and an inside bead filler located in an inside under an equipment on a vehicle, and an outside bead core and an outside bead filler located in an outside. The carcass layer includes a main body and turnbacks. The main body extends from the inside bead core to the outside bead core. Each of the turnbacks is turned back from the inside bead core or the outside bead core to an internal side of a belt layer. Here, each edge of the turnbacks provided at a tire inner peripheral side of the belt layer is located inside from each edge of the belt layer in a tread width direction. In addition, a height of the outside bead filler is lower than a height of the inside bead filler in a cross section along the tread width direction.

On a second thermo-module there are disposed a prism, an optical filter, and a sub-mount, via a base respectively. On the front side of the sub-mount, there are disposed a first photodetector and a second photodetector. The optical filter is structured with a crystal member that satisfies a condition that &#x3b1;+(1/n)&#xd7;(&#x394;n/&#x394;T) becomes not more than 3.5, where &#x3b1; is a coefficient of linear expansion, nis a refractive index at a normal temperature, and &#x394;n is a change of a refractive index corresponding to a temperature variation &#x394;T.

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.

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.

Tone parameter control apparatus

An electronic musical instrument has a tone generation mode selecting switch capable of selecting a tone generation mode associated with an arbitrary one of a keyboard instrument play mode, a stringed instrument play mode and a wind instrument play mode, and a CPU for controlling the tone generation mode for a tone generator in accordance with the selection. This electronic musical instrument serving as a so-called tone generator module, can be driven by a MIDI signal supplied to a MIDI circuit from an external unit.

Electronic musical instrument having a plurality of tone generation modes

A global envelope is input by a user and stored in a global envelope memory. At the respective envelope-controlled sine wave generators are generated envelope functions of the respective orders by modifying the input global envelope. The envelopes of component wave signals of a plurality of orders are independently controlled by the envelope functions having the respective orders in the generators, and a musical tone signal is synthesized by combining the envelope-controlled component wave signals.
