Description

Detailed Description of the Invention (a) Field of Industrial Application This invention is an electronic wind instrument that controls the sound level etc. by the amount of breath (press strength) and determines the pitch by pressing a combination of performance keys. Regarding.

(b) Prior Art Currently, electronic wind instruments have been put into practical use that control musical tones using fingering and pressing strength similar to those of wind instruments. Electronic wind instruments generate musical sound parameters based on information detected by pressing strength and fingering, and control the sound source device based on these musical sound parameters to generate musical sounds. Therefore, they have the flexibility that natural wind instruments do not have. Performance elements (operators) can be provided. As an example, a wheel switch has been conventionally provided. A wheel switch is an operator that can output analog manipulated data based on the rotation angle, and in conventional electronic wind instruments, this wheel switch is used for the pisoti bend function (the effect of raising or lowering the pitch steplessly from a specified pitch). was.

(e) Problems to be Solved by the Invention In addition to pitch bend, there are many tone parameters other than pitch bend that can be generated based on analog quantities using wheel rotation to enrich musical tone expression. For example, it is preferable that pronunciation effects such as vibrato can also be controlled steplessly from the O level to the maximum level.

However, in conventional electronic wind instruments, the function of the wheel switch was limited to the pitch bend function, as mentioned above, and it was not possible to change the depth of the vibrato. On the other hand, if the wheel switch position is fixed to the adjustment of the vibrato function, there is a problem in that the vibrato function cannot be sufficiently applied. For this reason, conventional electronic wind instruments have the drawback of insufficient expression of musical tones.

An object of the present invention is to provide an electronic wind instrument that solves the above problems by making it possible to switch the function of the wheel switch.

(d) Means for Solving the Problems The present invention provides an electronic wind instrument in which musical tones to be produced are controlled by musical tone parameters, in which an operator is provided at a position that can be operated during performance, and the amount of operation of this operator is controlled. A detection means for continuously detecting; a selection means for selecting a musical tone parameter to be controlled; and a baranota generation means for generating the selected musical tone parameter based on the detected operation amount. It is characterized by

Effects of the Invention In the electronic wind instrument of the invention, musical tone parameters generated based on the amount of operation of an operator such as a wheel switch are not fixed, but can be selected by a selection means. The selection means may be of any type as long as it can be operated by the player and the function switch provided on the musical instrument.

This makes it possible to control various musical piece parameters using the wheel switch, thereby expanding the range of performances. Furthermore, if the selection means is also constituted by a switch or the like that can be operated during the performance, it becomes possible to switch the tone parameters controlled by the wheel switches during the performance.

(f) Embodiment FIGS. 1A and 1B are external views of a controller 2 for an electronic wind instrument, which is an embodiment of the present invention. The same figure (A) is a front view, and the same figure (B) is a rear view. This electronic wind instrument consists of a controller 2 having a shape similar to that of the woodwind instrument shown in this figure, and a sound source Unisoto 1 (second
(see figure), which are connected with a connector cable.

In FIG. 1, this controller 2 has a shape similar to a woodwind instrument such as a soprano saxophone, and has a mouthpiece portion 3 at the tip. The player places his or her mouth on the mouthpiece section 3 and blows into the mouthpiece section 3 to play. A breath sensor 21 (second
(see figure) is provided. This breath sensor 21 detects the strength of breath (press strength). There is a pitch key on the outside of the device that determines the pitch within the octave of the musical tones to be produced. (7-1 to 7-13), octave key 8 (8-0
-8-2) are provided, and these pitch keys 7 and octave keys 8 constitute performance keys. The pitch can be determined by operating these performance keys with a fingering pattern (key pattern) similar to that of a saxophone. Further, a wheel switch 10 is provided on the back of the controller 2. The wheel switch 10 is an operator that can swing at a certain angle in the direction of the arrow in the figure, and is operated with the thumb of the right hand. The swing angle of this wheel switch 10 is detected by a permanent magnet and a Hall element.

That is, a permanent round stone is provided in the wheel switch 10, and a Hall element is provided in the controller body facing the permanent magnet. As the wheel switch 10 swings, the distance between the permanent magnet and the Hall element changes, and as the resistance value of the Hall element changes, the swing angle of the wheel switch 10 is electrically detected. Further, a connector opening 11 is provided at the lower part of the back surface of the controller 2.

FIG. 2 is a block diagram of the control section of the electronic wind instrument. This electronic wind instrument consists of a controller 2 shown in FIG. , is output as sound (musical sound).

The sound source Unison 1.1 is controlled by the CPU 20.

The CPU 20 is connected to each operating section via a bus 24. The bus 24 includes an interface 23 and a fingering data ROM 29. Tone data ROM30. Program RO
M31, data ROM 32 RAM 33, tone generator 34 and display section 27 are connected. The controller 2 is connected to the interface 23 via the A/D conversion circuit 22, and the foot switch 11 is connected to the interface 23.
and a function switch 5 are connected. The outputs of the breath sensor 21, wheel switch 10, and performance keys 7.8 are input from the controller 2 as operation data signals. Further, the function switch 5 includes a wheel mode switching switch 5a, a +1 switch 5b, a -1 switch 5C, a tone setting switch, and the like. Furthermore, the tone signal of the audible frequency generated by the tone generator 34 is processed by an effect circuit 35 that adds various effects such as acoustic effects, and a D/A conversion circuit 3.
6 and an amplifier 37 to a speaker system 40 . Is wheel mode switching switch 5a the same as wheel mode switching switch 10? ff [I This is a switch that switches the function with pisochihendo/vibrato.

The fingering data ROM 29 stores a table that associates the key patterns of the performance keys 7 and 8 with the pitches of the musical tones to be produced, and the timbre data ROM 32 stores the tones that can be produced by this sound source Unisoto 1. Waveform data etc. are stored. The program ROM 31 stores a program for controlling the operation of the tone generator, and the data ROM 32 stores various tone control data. Further, a wheel mode flag F and a pinch bend mode register R as shown in FIG. 3 are set in the RAM 33. The wheel mode flag F is a flag that stores whether the wheel switch 1'0 is responsible for the bitch bend function (pitch bend mode) or the vibrato function (vibrato mode), and when this flag is set, it is in vibrato mode. Show that. The pitch hend mode register R is a register for setting how much the pitch hend is to be raised or lowered when the wheel switch 10 is operated at its maximum in the pitch bend mode. This register stores a number from O to 5.

The maximum bit bend amount corresponding to each value is 5: Octave up 4: 5 degrees up 3: Whole tone asobu 2: Half step up l: whole tone down 0: Octave down It is.

FIGS. 4(A) and 4(B) are flowcharts showing the operation of the CPU 20. FIG. The same figure (A-) is the main routine, and the same figure (B) is the wheel mode changeover switch 5a, +1 switch 5b, -1 in the main routine.
This is a subroutine when the on-state of the switch 5c is detected.

First, the main routine shown in FIG. 3(A) will be explained. This operation starts when the electronic wind instrument is powered on. First, initialization processing such as resetting registers and flags is executed in nl.

This initialization process enables the electronic wind instrument to play. Next, an on event of the function switch is detected at n2. Wheel mode changeover switch 5 among function switch
When either the a or +1 switch 5b or the l switch 5C is turned on, the operation shown in FIG. 4B is executed.

Following this operation, the on/off state of each operator provided on the controller 2 is detected (n3 to n5). First, in n3, the key pattern of the performance keys is detected. By comparing the key pattern detected in this operation with the contents of the fingering data ROM 29, the specified pitch is determined. At n4, breath data is detected. Based on this data, the volume level of the musical tone to be produced is determined. Next, wheel switch data (wheel switch 10
(operated amount data) is detected (n5). Wheel switch
After detecting the notch data, the vibrato mode/bitch bend mode is determined with reference to the wheel mode flag F (n6). When in vibrato mode, proceed to n7 to determine the amount of vibrato based on the wheel switch data (n
7) Proceed to nlO. On the other hand, in bisoti bend mode n8
First, the maximum piston bend amount is read from the bi- and seven-chibend mode registers R. Next, in 09, the ratio of the current wheel switch data to the maximum wheel switch operation value is normalized by the read maximum pitch bend amount to calculate the pitch bend amount at this time, and then nl
Proceed to O. At nlO, the waveform data of the musical tone to be generated is determined and output to the tone generator 34, and at nil, the pitch of the musical tone to be generated is determined from the above data and output to the tone generator 34. Next, key-on/off data based on the volume and the output of the breath sensor 21 is output to the tone generator 34 to generate a musical tone.

During operation of this musical instrument, operations n2 to nl2 are repeatedly executed. Note that if the detected value of the breath sensor 21 is below a certain value, key-off data is sent to the tone generator 34, so no musical tone is produced no matter what operation is performed.

FIG. 2B shows a subroutine corresponding to an on event of some of the function switches. This operation is performed by wheel motor selector switch 5a, +1 switch 5b, -1 switch 5C.
is executed in response to an on event. First, n21~n
In step 23, it is determined which switch-on event has occurred. When the wheel mode changeover switch 5a is turned on, the process proceeds to n21-+n24, inverts the wheel mode flag F (n24), and returns. That is, the wheel mode changeover switch 5a is a toggle switch that can be turned on repeatedly to alternately set vibrato mode and pitch bend mode. If the +1 switch 5b is turned on, the process proceeds to n22→n25 and it is determined whether the bisoti bend register R is 5 or not. If register R is 5, there is no setting of a higher value, so the switch-on event is ignored and the process returns; if it is less than 5, l is added to the contents of register R and the process returns (n26). On the other hand, if the minus switch is turned on, proceed from n23 to n27, and judge whether the contents of the register are less than or equal to 0. If it is less than or equal to 0, return as is, and if it is greater than O, extract l from the contents of register R. Subtract (n28) and return. Through these operations, the setting of the maximum pitch bend amount can be changed using the plus switch and minus switch.

In this embodiment, the mode assigned to the wheel switch position is pitch bend/vibrato, but it is also possible to assign other functions. Furthermore, it is also possible to switch the functions of operators other than the wheel switch.

(0) Effects of the Invention As described above, according to the electronic wind instrument of the present invention, operators such as wheel switches can be used as operators for controlling a plurality of different musical tone parameters, so various settings can be made to suit the music being played. This makes it possible to express a wide range of musical tones.Also, if this setting change (selection means) can be made while the instrument is being played, it will be possible to control various musical tone parameters while playing a single song. can greatly improve the expressive power of
