Abstract

A musical tone control apparatus controls a musical tone corresponding to a movement itself of an object and the like which is detected by a detector. Such detector detects also a moving speed, a moving force, a moving angle or an intensity of given impulse of the object. In the case where the detector is mounted in the vicinity of a player's joint, the detector detects a revolving or bending angle of the player's joint. Hence, the musical tone can be controlled based on such angle of the player's joint. Thus, through this musical tone control apparatus, the player can generate a musical tone having, for example, a desirable tone pitch, a desirable volume and a desirable tone color based on the movement of the object or the player's joint.

Shown in Figure 16 405 is the amplifier units that amplify the output signal of acceleration transducer 1X, is made of the linear amplifier 406 and the logarithmic amplifier 407 that are connected in parallel.The 408th, select either party switch of output signal of linear amplifier 406 and logarithmic amplifier 407, the signal of selecting by this switch is fed into the input end 411 of acceleration peak value testing circuit 410.Acceleration peak value testing circuit 410 is peak values of the acceleration measured of sense acceleration sensor 1X, and the circuit between increase/degradation period, below its formation is narrated.

At first, the 412nd, comparator, its input end in the same way is connected input end 411 by resistance 413 (100K Ω).Secondly, resistance 415 (10K Ω) and capacitor 416 have constituted the integrating circuit that postpones acceleration signal Sa, and the output signal Sd of this integrating circuit supplies with the reverse input end of comparator 412 and the input end in the same way of comparator 420 by diode D1.Variable resistor VR is used for voltage V is carried out dividing potential drop and sets reference voltage V ref, and this reference voltage V ref is a reverse input end of supplying with comparator 420 by resistance 423 (100K Ω).This reference voltage V ref changes its magnitude of voltage by reverse input end and the discharging and recharging of the capacitor between the ground connection 424 that inserts in comparator 420.Also have, the reverse input end of comparator 420 anode by resistance 422, diode D3 and negative electrode in turn joins with input end in the same way, and anode, negative electrode and resistance 421 (10K Ω) and the input end 411 by diode D2 joins in turn simultaneously.

Get off, DFF1 delays trigger again, and " 1 " signal is fed into data input pin D, and the output signal of comparator 412 is then supplied with input end of clock.The output signal of delayed-trigger DFF1 is fed into central processing unit 450 as interrupt request singal INT.And supply with reset signal RS by 450 couples of delayed-trigger DFF1 of central processing unit.

The 425th, carry out the on-off element of on according to the output signal of comparison instrument 412, when becoming on-state, acceleration signal Sa is supplied with capacitor 426 and analog-to-digital converter 427.

The 430th, according to the time translation circuit of Tw during the increase of the output signal sense acceleration signal Sa of comparator 412, following its formation of explanation.

At first, the 431st, when being " 1 " signal, the output signal of comparator 412 connects, and the on-off element that disconnects when being " 0 " signal, one when becoming on-state, charges to capacitor 435 through the route of resistance 432 → switch 434 or the route of constant current source 433 → switch 434.That is to say, during the output signal of comparator 412 becomes " 1 " signal,, can be transformed to the charging voltage of capacitor 435 during this " 1 " signal to capacitor 435 chargings.At this moment, just can the convert charging characteristic by alteration switch 434.Also have, the charging voltage of capacitor 435 is to be transformed to count signal by simulation/counting transducer 442.

Next, 436 and 437 is to constitute resistance and the transistor that capacitor 435 is discharge routes (route resets), the base stage of transistor 437 is through after the resistance 438, is connected with the output terminal of comparator 412 by capacitor 440, simultaneously also by resistance 439 ground connection again.When this situation, transistor 437 rise in the output signal of comparison instrument 412, supply with base current by capacitor 440, resistance 438, just can conducting.It more than is exactly the formation of time translation circuit 430.

Also have, AN1 is an AND gate, on one side input end be negative logic, the output signal of comparator 412 just is fed into this input end.In addition, then supply with the output signal of comparator 420 at the input end of the another side of AND gate AN1.The output signal of this AND gate AN1 is fed into time translation circuit 445.The formation of time translation circuit 445 is identical with above-mentioned time/voltage conversion circuit 430, the output signal of AND gate AN1 is become " 1 " signal during be transformed to magnitude of voltage.The output signal of this time translation circuit 445 is to be converted to count signal by simulation/counting transducer 446.

It more than is exactly the formation of acceleration peak value testing circuit 410.

Below describe with regard to musical sound generation treatment circuit 460.This musical sound generation treatment circuit 460 is the circuit that produce various musical sounds according to each output signal control of simulation/counting transducer 427,442,446, by the register 451,452,453 of each output data of storing simulation/counting transducer 446,442,427; Each central processing unit 450 partly of control circuit, the stored program storer 455 that in this central processing unit 450, is used, the registers group 456 of interim store various kinds of data, switches set of forming by the switch (comprising tone color selector switch SEL (with reference to Figure 17)) of various instructions of indication and pattern 454 and tone generator 457 formations that note signal takes place.This situation, the note signal that is taken place by tone generator 457 is fed into sound system (diagram is omitted) and produces musical sound.

(2) work

Below the work of the 1st embodiment of above-mentioned formation is described.In addition, in the following description, switch 408,434 is for can be exchanged into each illustrated state.

(a) work of comparator 412,420

At first, the work to comparator 412,420 describes.

The player holds drum rod 402 (with reference to Figure 17), when required direction is brandished 1 time, just can be detected by acceleration transducer 1X with this action relevant acceleration of brandishing.And the acceleration signal of being measured by acceleration transducer 1X passes through the input end 411 that linear amplifier 408 is supplied with acceleration peak value testing circuits 410.At this moment, the acceleration signal Sa of supply input end 411 just is such curve of describing shown in Figure 18 (a).Here, the acceleration characteristic of action that is commonly referred to as people " brandishing " be as shown in the drawing like that, the characteristic of being described is earlier at the reverse acceleration (calling duration of work in advance during this) that demonstrates, then reach peak value, go under the decay gradually subsequently and become " 0 " to forward (want brandish direction) increased acceleration.

This situation is by the time t shown in Figure 18 (a) ₁₀Beginning is worked in advance, at time t ₁₁Just begin to move to forward.From this time t ₁₀C to t ₁₁Between, acceleration signal Sa is less than normal voltage Vref, also has, and the output signal Sd of the integrating circuit that is made of resistance 415 and capacitor 416 is also as shown in the drawing like that less than normal voltage Vref.Its result, diode D shown in Figure 16 ₁Just become off-state, and diode D ₂, D ₃Then become on-state, normal voltage Vref is then by resistance 422, diode D ₃Be additional to the reverse input end of comparator 412.Also have, capacitor 424 begins discharge by diode D2.Like this, normal voltage Vref reduces, at time t ₁₁Just consistent with acceleration signal Sa.At this, because diode D ₃The decline of forward voltage very small, be the reverse input end that directly is additional to comparator 412 so normal voltage Vref can be considered.Therefore, to time t ₁₁Till, the voltage that is additional to reverse input end will be higher than and is additional to the voltage of input end in the same way, and the output signal of comparator 412 then becomes " 0 " signal like that shown in Figure 18 (b).

And from time t ₁₁To time t ₁₂Between, the relation of acceleration signal Sa and normal voltage Vref and signal Sd then becomes:

Sa＞Vref＞Sd……(3)

Its result, diode D ₁, D ₂Just become off-state, and diode D ₃Then become on-state, comparator 412 just carries out relatively working of acceleration signal Sa and normal voltage Vref, by relatively working, the output signal of comparator 412 just shown in Figure 18 (b) like that from time t ₁₁Begin to become " 1 " signal.Also have, at time t ₁₁, because diode D ₂Become off-state, so the discharge route of capacitor 424 just is disconnected, so, capacitor 424 just can charge by variable resistor VR, resistance 423, that is to say, from time t ₁₁Rise, normal voltage Vref just rises slowly, just returns to starting potential soon.

Then, one to time t ₁₂, the signal Sd voltage Vref that just is above standard, its result, diode D ₁Just become on-state, and diode D ₃Then become off-state, comparator 412 degree of will speed up signal Sa and signal Sd compare.This situation, because signal Sd postpones 1 time of acceleration signal Sa, and the signal that it has tilted to diminish a little, so acceleration signal Sa keeps the relation of Sa＞Sd till reaching peak value always.Thereby, at time t ₁₂After, the output signal of comparator 412 is kept " 1 " signal.In addition, at time t ₁₂, the signal Sd one voltage Vref that is above standard, shown in Figure 18 (c), the output signal of comparator 420 then rises to " 1 " signal.

Then one to time t ₁₃, signal Sd surpasses acceleration signal Sa, and the output signal of comparator 412 just drops to " 0 " signal like that shown in Figure 18 (b) as a result.After, acceleration signal Sa just can not surpass signal Sd and normal voltage Vref, and its result is at this time t ₁₃After, the output signal of comparator 412 just becomes " 0 " signal.

Also have, from time t ₁₃To time t ₁₄Between, because signal Sd overgauge voltage Vref, so the output signal of comparator 420 is just kept " 1 " signal.And one to time t ₁₄, normal voltage Vref surpasses signal Sd, and its result, the output signal of comparator 420 just drop to " 0 " signal.After, signal Sd just becomes the value less than normal voltage Vref, so the output signal of comparator 420 is just kept " 0 " signal.

The output signal of above-mentioned comparator 412 is reversed and supplies with the input end on one side of AND gate AN1, and the output signal of comparator 420 is then directly supplied with the input end of the another side of AND gate AN1.The output signal of AND gate AN1 is just such as Figure 18 (d) shown in as a result for it, from time t ₁₃To time t ₁₄Between become " 1 " signal.

(b) meaning of the output signal of comparator 412, AND gate AN1

Here, the output signal with regard to comparator 412 become " 1 " signal during describe.

Though the output signal of comparator 412 is at the time t shown in Figure 18 (a) ₁₁～t ₁₃In be to become " 1 " signal, still, this time t ₁₁Can from figure, be clear that it is that signal for faster Sa is from bearing the positive time that is reversed to.The detection principle of this reversing time is as follows.

As shown in Figure 19, existing supposition is by the fiduciary level L after fixing ₁Acceleration signal Sa was detected from the time of negative sense rotating, then become the time ta shown in this figure its detection time, and measured the time that is later than actual reversing time.In addition, as this embodiment, along with the variation of the minus side of acceleration signal Sa and the corresponding fiduciary level L that falls ₂The time, (Vref is corresponding with normal voltage), acceleration signal Sa just becomes tb from the time of negative sense rotating, and its accuracy of detection improves greatly.

Also has time t ₁₃Be extremely to approach the time that acceleration signal Sa reaches peak value, the detection principle of this time to peak can be learnt from Figure 18 (a), be to compare as the acceleration signal Sa of original signal and the signal Sd that postpones behind this signal, the moment that signal Sd is surpassed acceleration signal Sa is judged as the time to peak of acceleration signal Sa.Detect principle according to this,, just can quite correctly detect time to peak by suitably selecting the time delay of signal Sd.

Can clearly learn from above-mentioned explanation, from time t shown in Figure 180 ₁₁To time t ₁₃Till time, just to become the time T w of " 1 " signal be corresponding to the time that forward increases with acceleration to the output signal of comparator 412.

Also has the time t that the output signal of comparator 420 descends ₁₄Be that signal Sd as inhibit signal debases the standard time of voltage, its result, the output signal of AND gate AN1 becomes the time T r of " 1 " signal, is corresponding in the time of forward decay with acceleration.

(c) processing of each output signal of comparator 412 and AND gate AN1

As mentioned above, in the output signal of comparator 412, have the expression acceleration increase during meaning, this output signal is fed into the binding post G and the time translation circuit 430 of on-off element 425.

The output signal of comparator 412 is supplied with the result of on-off element 425, makes on-off element 425 become the breakdown state during acceleration increases.In view of the above, during in the Tw, acceleration signal Sa is fed into capacitor 426.So, the terminal voltage of capacitor 426 just shown in Figure 18 (e) like that during increase in the Tw.And at time t as the time to peak of acceleration signal Sa ₁₃, on-off element 415 becomes off-state, its result, and the voltage in this moment of capacitor 426, promptly the crest voltage of signal Sa must be in maintenance.And the sustaining voltage of this capacitor 426 is being later than time t a little ₁₃Stipulated time t ₅₁Simulated/count transducer 427 and take a sample, and be transformed to count signal at this.

Also have, the output signal one of comparator 412 is fed into time translation circuit 430, is upgraded to the time t of " 1 " signal at this signal ₁₁, base current passes through by capacitor 440, the differentiating circuit inflow transistor 437 that resistance 438 is formed, and its result, savings just discharges by resistance 436, transistor 437 at the electric charge of 435 li in capacitor.That is to say, the terminal voltage of capacitor 435 shown in Figure 18 (f) like that, at time t ₁₁Be reset to 0V.In addition, at time t ₁₁, the output signal one of comparator 412 rises, and on-off element 431 just becomes on-state, and its result charges to capacitor 435 by resistance 432.Thereby the terminal voltage of capacitor 435 is just such shown in the solid line of Figure 18 (f) lining, according to the time t of certain charge characteristic from resetting ₁₁Begin to rise.Also have, when switch 434 is switched to constant current source 433 1 sides, then rise according to the characteristic shown in the dotted line of this figure.

The output signal one of comparator 412 drops to " 0 " signal, and 431 of on-off elements become off-state, stops to charge to capacitor 435.Also have, at this constantly, because transistor 437 has been in off-state, so at time t ₁₃After, the terminal voltage of capacitor 435 just remains unchanged.At this moment the magnitude of voltage that is kept owing to be according to free burial ground for the destitute decision between the charge period of capacitor 435, so just become with shown in Figure 180 during the corresponding magnitude of voltage of Tn.This sustaining voltage value is being later than time t like that slightly shown in Figure 18 (f) ₁₃The chamber time t ₅₂, sampled and be transformed to count signal at simulation/counting transducer 442.

Then, and the output signal of the corresponding AND gate AN1 of Tr is fed into time translation circuit 445 between the degradation period of acceleration signal Sa, at this, with above-mentioned time translation circuit 430 just the samely it be transformed to during the corresponding magnitude of voltage of Tr.And this magnitude of voltage is transformed to count signal in the regular hour by simulation/counting transducer 446.

(d) work of musical sound generation treatment circuit 460

Below the work of musical sound generation treatment circuit 460 is described.

Central processing unit 450 is according to the program in the storer 455, abides by process flow diagram shown in Figure 20 and carries out work, and control the work of musical sound generation treatment circuit 460 according to this.

At first, central processing unit 450 begins to carry out work from the step SP1 shown in Figure 20 (a), then moves on to step SP2 and carries out musical sound generation other processing in addition.Whether this processing for example scans each switch in the switches set 454, detect tone color and change etc., and the tone color of then changing tone generator 457 when conversion is arranged makes it to become specified tone color.At this moment central processing unit 450 is proceeded the work of step SP2 till d type flip flop DFF1 output interrupt request singal INT shown in Figure 16 always.

And interrupt request singal INT one is supplied to, and central processing unit 450 just moves on to step SP10 to processing, just carries out Interrupt Process later on.At first, move on to step SP11 output reset signal RS, d type flip flop DFF1 is resetted.As a result, interrupt request singal INT just stops.Then move on to step SP12, the data in the register 453 are read in as volume data VOL.In this embodiment, and the peak value of the acceleration signal Sa that exports respectively of simulation/counting transducer 427,442,446, increase during between Tw, degradation period the corresponding count signal of Tr deposit register 453,452,451 in, the tone control data of these data as the control musical sound used.This situation, such as shown in figure 21, volume data VOL as the volume of indication musical sound uses the data in the register 453, and the rise sound data ATK of the data in the register 452 as the rise time of indication musical sound used, also have, the data in the register 451 are used as closure (decay) the data CLS between the degradation period of indication musical sound.

At step SP12, volume data VOL one is read into, and VOL just is fed into generater of musical tone 457 at this volume data of step SP13, sets the volume of note signal.Then move on to step SP14, read in the data ATK that rises in the register 452, supply with generater of musical tone 457 playing a sound data ATK then, set the rise time (step SP15) of note signal.Then, 457 supplies go code to generater of musical tone once moving on to step SP16.Its result, generater of musical tone 457 just begins to take place musical sound according to the sound data ATK and the volume data VOL that are supplied with.And central processing unit 450 moves on to step SP18 through (step SP17) after the suitable stand-by period, reads in the closed data CLS in the register 451.Move on to step SP19 then, closed data CLS is supplied with happy generator 457.Generater of musical tone 457 just allows the note signal decay make it to form and according to the corresponding envelope of the decaying die-away time of closed data CLS appointment, like this, initial musical sound takes place to handle and just is through with.The processing one of this step SP19 finishes, and just returning master routine by step SP20 is step SP2.And, after, whenever d type flip flop DFF1 output interrupt request singal, just carry out above-mentioned Interrupt Process, promptly musical sound is handled.

Still have, the stand-by period of above-mentioned step SP17 handles, and can also omit according to the kind difference of the musical sound that takes place.

More than be the work of this embodiment.

(3) effect

In above-mentioned the 1st embodiment, can bring into play following significant effect.

Feature to the input signal of the change of acceleration signal Sa etc., during promptly increasing, between degradation period, when peak value etc. detects, originally the method for Cai Yonging is by comparing so that input signal is detected with certain level, perhaps input signal is transformed to after the count signal, detects during each and peak value by software processes.

At this moment, adopt the method that compares with certain level, because dynamic range is little, so for example will sample just very difficult to the activity of fierceness to slow activity from the people.Also have, adopt the method for software processes since with the relation of the execution speed of central processing unit, the sudden turn of events that correctly detect input signal is difficult.That is to say that will detect the feature of input signal, its quantity of information increases in a large number, and general central processing unit just is unable to cope with processing when the input signal sudden turn of events.Also have, want sense acceleration etc. will 3 directions of X, Y, Z be detected, and one form a plurality of input structures so that when detecting the feature of acceleration signal of relevant these all directions, because the relation of processing speed and processing accuracy etc., to all directions, need central means respectively, so the structure of device just becomes very complicated, this also involves the problem that raises the cost with regard to generation.

In contrast, adopt the foregoing description, measure the peak value moment by input signal (acceleration signal Sa) and the signal that this input signal is postponed are compared because be, so just can correctly measure the peak value moment, peak value without central processing unit, and can be along with input signal corresponding compensation standard voltage Vref, so can reach correctly detect increase during, the effect between degradation period.

The distortion of (4) first embodiment and application examples

Below, the variation of the foregoing description is described.

(a) each output signal of simulation/counting transducer 427,442,446 also can be used to control other parameter of musical sound, i.e. tone, tone color, radio distance-measuring or the performance degree (carrying out speed) etc. of rhythm music performance apparatus automatically.Here said radio distance-measuring, be the preset work of various levers of on operation board, carrying out for the characteristic that determines musical sound etc., carry out many preset in advance and it is stored, just can select arbitrary preset state according to the output of acceleration transducer then.

(b) also can by allow musical sound based on the acceleration transducer 1X of directions X form with below drum face on stretch tight the side drum that rings string sound and face upward bat to open sound corresponding, allow musical sound based on the acceleration 1Y of Y direction form in addition and face upward bat to close sound sound corresponding with the sound of bass drum, and be split up into level, vertical direction drum rod 402 is suitable, produce the rhythm note.So, for example drum rod 402 is brandished to vertical direction (→ ↓) from horizontal direction soon, in the extremely short time, just can be played out 2 rhythm notes continuously.

(c) combined with the angular transducer of the angle that detects arm etc., so just can carry out more various musical sound and control.

For example, control the key of indicating tone, control the envelope that connection (time that begins to pronounce) has reached the sound of sound, peak value, decay etc. according to brandishing of drum rod 402 according to the angle of arm.Here, Figure 22 (a) and (b) are states of representing respectively the angle of each arm to be brandished as S1 S2 drum rod 402 downwards.So, by the brandish method of the angle of player's arm with drum rod 40 2 combined, just can by required volume envelope musical sound take place at required tone, so that can realize always unexistent new performance operation and playing effect.

At this, show that an example detects the angular transducer of the angle of arm.

Figure 23 is the example that is installed in the angular transducer on the special-purpose clothes in advance.Among the figure, AS1, AS2 are the angular transducers that detects the opening angle of arm (upper arm) and human body.This angular transducer AS1, AS2 be sample as shown in figure 24, is by the pot 480 of rotary type, with the actuator 481 of the moving element interlock of pot 480, can be free to slide bearing member 482 and actuator 481 is attached to the spring 483 that bears member 482 1 sides and constituting of this actuator 481 of ground folding and unfolding.At this moment, make relative rotary motion bearing between member 482 and the pot 4S0, actuator 481 like this, just can obtain the respectively angle signal in the moment from pot 480 for the rotation of 480 dos of pot with the respective amount that rotatablely moves.

In example shown in Figure 23, Yi Bian pot 480 be fixing piggyback, bearing member 482 on one side is to be fixed on upper arm parts, just can export from pot 480 with the corresponding angle signal of horizontal opening angle of arm.This situation by changing the installation site of angular transducer AS1, AS2, just can that works be as shown in figure 22 measured the aperture of the fore-and-aft direction of arm.

In addition, such as shown in figure 23, angular transducer AS3, the AS4 of the angle of bend when detecting also can be set, the combination according to the output signal of each angular transducer AS1～AS4 decides key then.So, just can in wide whole range, specify key, also can carry out various change and can bring into play new playing effect it soon simultaneously.Here represent to be placed in the active state of the angular transducer AS3 (AS4) on the elbow with for referencial use with Figure 25.

Also have, shown in Figure 23 490 is folding and unfolding circuit shown in Figure 16 and sound boxes to system, resembles to make the diagram to be installed in player's structure on one's body, and then this use is quite easily.Also have, this situation also can be located at the box outside to generater of musical tone and sound system etc.

Also have, other example as angular transducer, also can constitute like that as shown in figure 26, ultrasonic transmitter 495a, 496a and ultrasonic receiver 495b, 496b are combined, measure the opening angle of arm then according to the hyperacoustic conduction time between them.

(d) in embodiment shown in Figure 16, be that acceleration transducer 1X, 1Y, 1Z are located at excellent 402 the insides of drum, but also can be to this change, and constitute as directly or by certain mounted apparatus be installed in hand, pin, neck, and arm etc., the acceleration of these parts detected.

Figure 27 is installed on hand an example to acceleration transducer, as shown in the figure, acceleration transducer 1X, 1Y, 1Z etc. is installed in each finger top (with reference to Figure 28) partly of gloves 498.By such formation,,, can carry out various performances with usual feeling so the player need not to use the utensil such as the drum rod owing to can detect and the brandishing and other action relevant acceleration of player's hand.

(B) the 2nd embodiment

Musical sound forms circuit 615 and forms note signal according to the key data KC, the connection signal KON that are supplied with, cut-off signal KOF.That is to say that this musical sound formation circuit 615 constitutes to form has the corresponding tone with key data KC, the note signal of the tone color that preestablishes.And the note signal that is formed circuit 615 outputs by this musical sound is to supply with sound system 616 to pronounce as musical sound.

Below, the work to above-mentioned the 3rd embodiment describes with reference to the processing flow chart of Figure 47 and central processing unit 610 shown in Figure 48.Figure 47 is the process flow diagram of master routine, and central processing unit 610 just carries out the processing shown in this process flow diagram when flat repeatedly.

At first,, read in service data Ds, Dn, Df that B-register 609 is deposited, then,, judge according to service data D whether connect K switch n has pressed at step S2 at step S1.When being service data Dn for " 0 ", just judge connect K switch n by according to, and enter step S3, when service data Dn be " 1 ", then judge connection K switch n not by by and enter step S4.Then, at step S4, judge that according to service data Ds # connects K switch s and whether pressed.When being service data Ds, judge that # connects K switch s and pinned and proceed to step S5, and service data D5 is when be " 1 " for " 0 ", then judge # connection K switch s be not by according to and enter step S6.And then, at step S6, then according to service data Df judge b connect K switch f whether by by, when being service data Df for " 0 ", with regard to judge b connect K switch f by according to and enter step S7, and service data Df is when be " 1 ", then judge b connection K switch f not by by and enter step S8.In this step S8, the connection data KOND that is deposited with the certain memory block in the random access memory 612 become " 2 " after, enter step S9.Also have,, the connection data KOND that is deposited with in the random access memory 612 is become " 0 ", "+1 ", " 1 " respectively afterwards, enter step S9 at above steps S3, S5, S7.This step S9 is a key handling procedure described later, after carrying out this step S9, returns step S1 once more.

Below, with reference to Figure 48 the key handling procedure is described.

At first, at step SP1, judge whether the old connection data OLDKOND deposited the predefined memory block in the random access memory 612 in is consistent with new connection data KOND, just returns master routine during OLDKOND=KOND, just enter step SP2 during OLDKOND ≠ KOND.At this step SP2, the old connection data OLDKOND that is deposited with in the random access memory 612 is rewritten as new connection data KOND.Then, at step SP3, judge whether to connect data KOND=-2, when connecting data KOND=-2, just enter step SP4, connection data KOND ≠-2 o'clock then enters step SP5.At step SP5, read in the detection data Da～Dd that has 608 li of A-registers, then at step SR6, decide key data KC according to the combination of the detection data Da that reads in, Db, Dc, Dd.At this moment, the relation of the combination of detection data Da, Db, Dc, Dd and key data KC then as shown in figure 46.At this, when being as shown in figure 43 states,, be " 1 " entirely so detect data Da, Db, Dc, Dd because each detector switch a, b, c, d disconnect as angle detector 602.At this moment, just obtain and tone C ₃Corresponding key data KC=60.

Then, at step SP7, judge whether to be key data KC=0, just return master routine during KC=0, KC ≠ 0 o'clock then enters step SP8.At this step SP8, be added on key data KC connecting data KOND, the data KC of addition result as new key.That is to say that when # connection K switch s has been pressed, at the step S5 of above-mentioned master routine, then become and connect data KOND=+1, so, at step SP8, KC adds 1 in the key data, just is transformed to and the corresponding key data of the tone KC that improves semitone.For example with pitch C ₃Corresponding key data KC=60 is transformed to and the corresponding key data of tone C# KC=61.Otherwise, when b connection K switch f has been pressed,, then become and connect data KOND=-1 at the step S7 of above-mentioned master routine, so, at step SP8, KC deducts 1 from the key data, is transformed to and the corresponding key data of the tone KC that reduces semitone.For example, with tone C ₃Corresponding key data KC=60 is transformed to the (B with tone Cb3 ₂) corresponding key data KC=59.

Next, at step SP9, output is exported connection signal KOND then at the key data KC that step SP8 calculates.These data are supplied with musical sound successively by bus 613 and are formed circuit 615, and so, the formation work that musical sound forms the note signal of circuit 615 just begins, from the musical sound of sound system 616 generations with the corresponding tone of key data KC.
