Fig. 3 is the process flow diagram of the example representing the process performed in the music performance apparatus main body involved by present embodiment.As shown in Figure 3, the CPU21 of music performance apparatus main body 11 performs the initialization process (step 301) comprising the data of RAM26 or the removing of mark etc.In initialization process, timer interruption (time interrupt) is removed.If relieve timer interruption, then in music performance apparatus main body 11, read in the sensor values of geomagnetic sensor 22 and the sensor values of acceleration transducer 23 by CPU21 with predetermined time interval, and it is saved in RAM26 respectively.And, in initialization process, based on the initial value of geomagnetic sensor 22 and the initial value of acceleration transducer 23, obtain the initial position of music performance apparatus main body 11, and it is also stored in RAM26.Current location acquired by obtaining in process (step 304) in the current location of following explanation becomes the relative position relative to above-mentioned initial position.After initialization process, repeatedly perform step 302 ~ 310.

CPU21 is obtained the sensor values (acceleration transducer value) of the acceleration transducer 23 obtained by interrupt processing and is stored in RAM26 (step 302).And CPU21 obtains the sensor values (geomagnetic sensor value) (step 303) of the geomagnetic sensor 22 obtained by interrupt processing.

Then, CPU21 performs current location and obtains process (step 304).Fig. 4 represents that the current location involved by present embodiment obtains the process flow diagram of the example of process.As shown in Figure 4, geomagnetic sensor value that CPU21 preserves based on RAM26, that obtain in the step 303 of previous execution and the geomagnetic sensor value obtained in this place of execution step 303, calculate the moving direction (step 401) of music performance apparatus main body 11.As mentioned above, the geomagnetic sensor 22 involved by present embodiment is 3 axle geomagnetic sensors, so the tri-vector that can form based on the difference of being divided by each one-tenth of x composition, y composition, z composition obtains direction.

And, acceleration transducer value that CPU21 preserves based on RAM26, that obtain in the step 302 of previous execution and the acceleration transducer value obtained in this step 302 performed, calculate the amount of movement (step 402) of music performance apparatus main body 11.This can obtain by using the difference (time interval) obtaining the moment of acceleration transducer value and respective acceleration transducer value to carry out 2 integrations.Then, previous positional information, the moving direction obtained respectively in step 401,402 and amount of movement that CPU21 preserves based on RAM26, calculate the coordinate (step 403) of current location.CPU21 judges whether the coordinate calculated there occurs change (step 404) relative to previous position coordinates.When being judged as "Yes" in step 404, CPU21 preserves the coordinate of the current location calculated in RAM26, as new positional information (step 405).

After current location obtains process (step 304), CPU21 performs main areas setting process (step 305).Be configured in the present embodiment, player uses music performance apparatus main body 11, the summit of appointed area, and the region that the vertical line that the plane after the two dimensional surface of being delimited by summit is projected on ground surface and the summit from this plane extend delimited is main areas.And, in the present embodiment, delimit out the main areas that music performance apparatus main body 10 can be used to produce musical sound.And, as described later, establish with the pitch of the actual musical sound that should send the subregion associated by setting in main areas, produce actual musical sound.Below, the situation that use 4 summits set main areas is described.Fig. 5 is the process flow diagram of the example of the main areas setting process represented involved by present embodiment.

As shown in Figure 5, CPU21 judges whether the main areas configuration switch in input part 18 is switched on (step 501).When being judged as "Yes" in step 501, CPU21 obtains the positional information that RAM26 preserves, and it can be used as the coordinate on summit (apex coordinate) to be stored in RAM26 (step 502).Then, CPU21 will represent in RAM26 that the Parameter N of number of vertices is from adding 1 (step 503).In addition, in the present embodiment, above-mentioned parameter N is initialized to " 0 " in initialization process (step 301 of Fig. 3).Then, CPU21 judges that whether Parameter N is than " 4 " large (step 504).When being judged as "No" in step 504, terminate main areas setting process.

Be judged as in step 504 that the "Yes" meaning refers to that 4 apex coordinates have been stored in RAM26.Therefore, when being judged as "Yes" in step 504, CPU21 obtains the information (step 505) of the two dimensional surface (quadrilateral) of being delimited by 4 apex coordinates.Then, CPU21 is based on the information of the quadrilateral acquired by expression, obtain and this quadrilateral is projected to ground surface and the position on the summit of the quadrilateral obtained, and in the form of the main areas information of main areas is stored in RAM26 and tone color (step 506).Afterwards, the Parameter N in RAM26 is initialized as " 0 " by CPU21, and, main areas is set mark and be set as " 1 " (step 507).

In the present embodiment, specify summit by player, the main areas based on the plane of being delimited by summit can be set.In the above-described embodiment, be that the plane (quadrilateral) of 4 is set as main areas by number of vertices, but by changing number of vertices, the main areas of the arbitrary polygons such as triangle can be set.

Fig. 7 is the figure that outline represents the decision of the main areas involved by present embodiment.Music performance apparatus main body when mark 71 ~ 74 represents that player has connected main configuration switch respectively.The front position of the music performance apparatus main body in mark 71 ~ 74 is respectively:

P1 (mark 71): (x ₁, y ₁, z ₁)

P2 (mark 72): (x ₂, y ₂, z ₂)

P3 (mark 73): (x ₃, y ₃, z ₃)

P4 (mark 74): (x ₄, y ₄, z ₄),

These 4 coordinates to be connected with straight line and the plane obtained represents with mark 700.

And, plane 700 is being projected to ground surface (z coordinate=z ₀) and in the plane 701 obtained, the coordinate y on summit is:

(x ₁，y ₁，z ₀)

(x ₂，y ₂，z ₀)

(x ₃，y ₃，z ₀)

(x ₄，y ₄，z ₀)

In the present embodiment, by 4 coordinate (x ₁, y ₁, z ₀), (x ₂, y ₂, z ₀), (x ₃, y ₃, z ₀), (x ₄, y ₄, z ₀) plane of delimiting and be set as main areas from the space 710 that the vertical line 75 ~ 78 that these 4 coordinates extend delimited.As described later, music performance apparatus main body 11, when being positioned at above-mentioned space 710, can produce musical sound by brandishing music performance apparatus main body 11.In addition, about setting and the shape in region, also other modes can be had.To describe later this.

If main areas setting process (step 305) terminates, then CPU21 performs tone color setting process (step 306).Fig. 6 is the process flow diagram of the example of the tone color setting process represented involved by present embodiment.As shown in Figure 6, CPU21 judges whether main areas setting mark is " 1 " (step 601).When being judged as "No" in step 601, terminate tone color setting process.

When being judged as "Yes" in step 601, CPU21 judges that tone color confirms whether switch is switched on (step 602).When being judged as "Yes" in step 602, CPU21 generates the note open event (step 603) of the timbre information comprised based on the parameter TN representing tone color.This parameter TN is such as the tone color number for determining tone color uniquely.In this note open event, represent volume level (volume level) as long as or the information of pitch predetermined.Then, CPU21 exports the note open event (step 604) generated to I/F26.I/F27 makes infrared communications set 24 note open event be sent with infrared signal.Infrared signal from infrared communications set 24 is received by the infrared communications set 33 in musical instrument portion 19.Thus, in musical instrument portion 19, send the musical sound of regulation pitch.To describe later for the pronunciation in musical instrument portion 19.

After step 604, CPU21 judges to determine whether switch is switched on (step 605).When being judged as "No" in step 605, CPU21 will represent that the parameter TN of tone color is from adding 1 (step 606), and returns step 602.When being judged as "Yes" in step 605, the timbre information shown in parameter TN is associated with the information of main areas by CPU21, and in the form of the main areas be stored in RAM26 and tone color (step 607).Then, main areas is set Flag Reset as " 0 " (step 608) by CPU21.

Fig. 8 is the figure of the example of the form representing main areas in the RAM involved by present embodiment and tone color.As shown in Figure 8, the record (for example, referring to mark 801) of the form 800 of the main areas involved by present embodiment and tone color has main areas ID, the coordinate of vertex position (1 ~ summit, summit 4) and these projects of tone color.Main areas ID is used for determining record uniquely, is the number selected by CPU21 when the record of the form 800 generating main areas and tone color.In the present embodiment, the tone color of the musical instrument that pitch can be specified variable is configured to.In the example of fig. 8, the idiophonic tone color that the such pitch of vibraphone, xylophone, timpani is variable is set with.The tone color of the musical instrument (keyboard instrument, stringed musical instrument, wind instrument etc.) that can set beyond above-mentioned percussion instrument can certainly be configured to.

And the coordinate as vertex position preserves the two-dimensional coordinate (x, y) in x direction, y direction.This is because as described above, the main areas involved by present embodiment is the three dimensions that the plane based on such as 4 summits on ground surface and the vertical line 75 ~ 78 that extends from these 4 summits delimited, and z coordinate is arbitrary.

If tone color setting process (step 306) terminates, then CPU21 performs subregion setting process (step 307).Fig. 9 is the process flow diagram of the example of the subregion setting process represented involved by present embodiment.As shown in Figure 9, CPU21 obtains the positional information (step 901) of the music performance apparatus main body 11 that RAM26 preserves, and judges whether music performance apparatus main body 11 is positioned at certain main areas (step 902).When being judged as "No" in step 902, terminate subregion setting process.

When being judged as "Yes" in step 902, CPU21 judges in the input part 28 of music performance apparatus main body 11, whether center configuration switch is switched on (step 903).When being judged as "No" in step 903, terminate subregion setting process.When being judged as "Yes" in step 903, CPU21 judges whether center configuration switch is new connection (step 904).When being judged as "Yes" in step 904, CPU21 is using the positional information (coordinate (x of the positional information of music performance apparatus main body 11 as center C _c, y _c, z _c)) be stored in RAM26 (step 905).This position becomes the reference position of following set subregion.

When being judged as "No" in step 904, when that is switch is in connection always, or after execution of step 905, CPU21 judges whether center configuration switch is disconnected (step 906).When being judged as "No" in step 906, terminate subregion setting process.When being judged as "Yes" in step 906, the positional information (coordinate (x of the position P of the music performance apparatus main body 11 when the positional information of music performance apparatus main body 11 disconnects as center configuration switch by CPU21 _p, y _p, z _p)), be stored in RAM26 (step 907).And in step 907, CPU21 calculates the distance d between position C and position P _p.CPU21 will be position C with center and through the radius d of position P _pscope (disk: circular plane) determine as subregion (step 908), and will be used for determining that the information (coordinate of center C, the coordinate of position P (also referred to as " through position ") and radius d) of subregion is stored in the form (step 909) of subregion in RAM26 and pitch.In step 909 in the information of form being stored in subregion and pitch, also comprise the main areas ID for determining the main areas that subregion is subordinate to and the subregion ID for determining subregion.Afterwards, the subregion in RAM26 is set traffic sign placement as " 1 " (step 910) by CPU21.

As described above, in the first embodiment, player is wanting the position being set to center C, the center configuration switch of music performance apparatus main body 11 is connected, when maintaining this state, move to the position suitable with radius, make center configuration switch disconnect in this position, thus, the position P process that can disconnect by position C centered by the position connected by center configuration switch and from center configuration switch, the plane of the circle of radius d (d: the distance between center C and position P), be set as subregion.

Figure 11 is the figure that outline represents the decision of the subregion involved by present embodiment.Mark 100 represents the music performance apparatus main body during configuration switch connection of center, music performance apparatus main body when mark 101 expression center configuration switchs disconnect.Conveniently, in fig. 11, being set to player makes music performance apparatus main body move horizontally and observe the state of this music performance apparatus main body from upside.

By player, the center configuration switch of music performance apparatus main body is connected, using the coordinate (x of the front position of music performance apparatus main body 100 as center C _c, y _c, z _c) be stored in RAM26, if when the state that the center of maintenance configuration switch is connected, make music performance apparatus main body 11 move and at desired disconnection center, position configuration switch, then obtain the coordinate (x of position P _p, y _p, z _p), as the front position of music performance apparatus main body 101, and, calculate the distance d between center C and position P _p.Thus, by centered by the C of center, from the radius d of position P process _pthe plane 1000 of circle be set to subregion.As described later, the front end (geomagnetic sensor 22) of music performance apparatus main body 11 is positioned at this subregion or from subregion process, produces musical sound thus.

In addition, in the example of Figure 11, player makes music performance apparatus main body 11 move horizontally, therefore, circular plane relative to the parallel fetch bit of ground surface, but is not limited to this, the plane of the circle set by above-mentioned player also can relative to ground surface keep arbitrarily angled come fetch bit.And, about the setting in region, also can additive method be considered.

If subregion setting process (step 307) terminates, then CPU21 performs pitch setting process (step 308).Figure 10 is the process flow diagram of the example of the pitch setting process represented involved by present embodiment.In addition, input part 28 confirms switch to specify pitch to have pitch and determines switch.Also this switch can be used as by switching other above-mentioned switches.And the parameter (such as, based on the pitch information of MIDI) of the expression pitch used in the pitch setting process of Figure 10 is set to initial value (such as, double bass) in initialization process (step 301).As shown in Figure 10, CPU21 judges whether subregion setting mark is " 1 " (step 1001).When being judged as "No" in step 1001, terminate pitch setting process.

When being judged as "Yes" in step 1001, CPU21 judges that pitch confirms whether switch is switched on (step 1002).When being judged as "Yes" in step 1002, CPU21 generates the note open event (step 1003) comprising pitch information, and this pitch information is the information based on the Parameter N N representing pitch.In this note open event, as long as represent that the information of volume level or tone color is predetermined.Then, CPU21 exports the note open event (step 1004) generated to I/F26.I/F27 makes infrared communications set 24 note open event be sent with infrared signal.Infrared signal from infrared communications set 24 is received by the infrared communications set 33 in musical instrument portion 19.Thus, in musical instrument portion 19, send the musical sound of regulation pitch.

After step 1004, CPU21 judges to confirm whether switch is switched on (step 1005).When being judged as "No" in step 1005, CPU21 will represent that the Parameter N N of pitch is from adding 1 (step 1006), returns step 1002.When being judged as "Yes" in step 1005, the pitch information shown in Parameter N N is associated with the information of subregion by CPU21, and the form (step 1007) of the subregion be stored in RAM26 and pitch.Then, subregion is set Flag Reset as " 0 " (step 1008) by CPU21.

In the pitch setting process shown in Figure 10, when pitch confirms that switch is switched on, send the musical sound than a previous high pitch.Desired pitch, by making confirmation switch connection when sending the musical sound of desired pitch, can be set up corresponding with subregion by player.Figure 12 is the figure of the example of the form representing subregion in the RAM involved by present embodiment and pitch.As shown in Figure 12, the record (for example, referring to mark 1201) of the form 1200 of the subregion involved by present embodiment and pitch has main areas ID, subregion ID, the coordinate of center C, coordinate, radius d and these projects of pitch through position P.

Main areas ID is the main areas ID for determining the main areas that subregion is positioned at.Subregion ID is the number selected by CPU21 when the record of the form 1200 generating subregion and pitch.

If pitch setting process (step 308) terminates, then CPU21 performs pronunciation timing check processing (step 309).Figure 13 is the process flow diagram of the example of the pronunciation timing check processing represented involved by present embodiment.CPU21 obtains the positional information (step 1301) that RAM26 preserves, and with reference to the form of the main areas in RAM26 and tone color, judges whether music performance apparatus main body 11 is positioned at main areas (step 1302).When being judged as "No" in step 1302, the maximal value of the acceleration transducer preserved by RAM26 is reset to " 0 " (step 1303).

When being judged as "Yes" in step 1302, CPU21 judges that whether the acceleration transducer value obtained in step 302 is than setting α large (step 1304).Setting α is the arbitrary value larger than 0, as long as can detect the situation of being brandished music performance apparatus main body 11 by player.When being judged as "No" in step 1304, proceed to step 1307.When being judged as "Yes" in step 1304, CPU21 judges the maximal value large (step 1305) whether acceleration transducer value preserves than RAM26.When being judged as "No" in step 1305, proceed to step 1307.

When being judged as "Yes" in step 1305, the acceleration transducer value acquired by CPU21 preserves, as the maximal value (step 1306) in RAM26.Then, CPU21 judge music performance apparatus main body 11 position whether tangent with subregion or whether from subregion through (step 1307).In step 1307, CPU21 determines the record group with the main areas ID being judged as the main areas in its region in step 1302 in the form of subregion and pitch, respective with reference to this record, the coordinate of center C, through coordinate and the radius of position P, obtain the information for determining the plane to the circle that subregion specifies, the position of this music performance apparatus main body 11 obtained from geomagnetic sensor 22 etc. judging that RAM26 preserves whether with the plane contact of subregion, or the track of the music performance apparatus main body 11 obtained according to the coordinate of the coordinate of previous process and this process whether with the crossing on the same level of subregion.When being judged as "No" in step 1307, terminate pronunciation timing check processing.

When being judged as "Yes" in step 1307, CPU21 be judged as that RAM26 preserves, whether establish corresponding pronunciation situation with this subregion be " in noise reduction " (step 1308).When being judged as "Yes" in step 1308, CPU21 performs note open event process (step 1309).In the present embodiment, pronunciation situation and every sub regions are set up corresponding and are stored in RAM26, in the sound source part 31 in musical instrument portion 19, represent and this subregion whether establish the tone color that associates be (pronouncing in situation=pronunciation) or whether by noise reduction (pronouncing in situation=noise reduction) in pronouncing.

Figure 14 is the process flow diagram of the example of the note open event generating process represented involved by present embodiment.As shown in Figure 14, the maximal value of acceleration transducer value that CPU21 preserves based on RAM26 determines volume level (velocity of sound) (step 1401).

If the maximal value of degree of will speed up sensor is set to Amax, the maximal value of volume level (velocity of sound) is set to Vmax, then volume level Vel such as can obtain as follows.

Vel＝a·Amax

(wherein, if aAmax > Vmax, then Vel=Vmax, in addition, a is the positive coefficient of regulation)

Then, the main areas in CPU21 reference RAM26 and the form of tone color, determine the record for the main areas residing for music performance apparatus main body 11, the tone color in determined record determined the tone color (step 1402) for the musical sound that should send.And, subregion in CPU21 reference RAM23 and the form of pitch, in the main areas residing for music performance apparatus main body 11, determine the record of the subregion of or process tangent for music performance apparatus main body, the pitch in determined record is determined the pitch (step 1403) for the musical sound that should send.CPU21 generates the note open event (step 1404) comprising determined volume level (velocity of sound), tone color and pitch.

Generated note open event is exported (step 1405) to I/F27 by CPU21.I/F27 makes infrared communications set 24 note open event be sent with infrared signal.Infrared signal from infrared communications set 24 is received by the infrared communications set 33 in musical instrument portion 19.Afterwards, the pronunciation situation in RAM26 changes to " in pronunciation " (step 1406) by CPU21.

If pronunciation timing check processing (step 309) terminates, then CPU21 execution parameter communication process (step 310).About parameter communication process (step 310), be described together with the parameter communication process in musical instrument portion 19 described later.

Figure 15 is the figure that outline represents the example of the pitch of subregion and the correspondence set in the subregion setting process of the music performance apparatus main body involved by present embodiment and pitch setting process.In this example embodiment, in subregion setting process, the main areas (reference marker 1500) of being delimited by projecting plane 1510 and the vertical line that extends from its summit, be set with subregion (reference marker 150 ~ 153).The subregion ID of subregion 150 ~ 153 is " 0 " ~ " 3 " respectively, subregion 150 ~ 153 is distributed respectively to the pitch of C3 ~ F3.These information are kept in the subregion of RAM26 and the form of pitch.

Such as, wave music performance apparatus main body (mark 1501) under player, if the front end of this music performance apparatus main body (reference marker 1502) is through subregion 150, then send the musical sound of C3 pitch.Equally, player's Back stroke music performance apparatus main body (reference marker 1503), if the front end of this music performance apparatus main body (reference marker 1504) is through subregion 151, then sends the musical sound of D3 pitch.In addition, tone color establishes corresponding with main areas 1500.

Figure 16 is the process flow diagram of the example representing the process performed in the musical instrument portion involved by present embodiment.The CPU12 in musical instrument portion 19 perform comprise RAM15 data dump, display part 16 picture on piclear, sound source part 31 the initialization process (step 1601) of removing etc.Then, CPU12 performs switch process (step 1602).In switch process, such as, CPU12 according to the switching manipulation of input part 17, set for the musical sound that should send, the parameter etc. of effect sound.The parameter (such as, the degree of depth etc. of reverberation) of set effect sound is stored in RAM15.And, in switch process, also can be edited by switching manipulation and to be sent from music performance apparatus main body 11 by parameter communication process described later and to be stored in the RAM15 in musical instrument portion 19, main areas and the form of tone color and the form of subregion and pitch.In this editor, also can revise vertex position for specifying main areas and change tone color, or the position of subregion or size can be revised and change pitch.

Then, CPU12 judges whether I/F13 newly have received note open event (step 1603).When being judged as "Yes" in step 1603, CPU12 performs pronunciation process (step 1604).In pronunciation process, CPU12 exports received note open event to sound source part 31.Sound source part 31 reads the Wave data of ROM according to the tone color that note open event comprises.And its reading speed is dependent on the pitch that note open event comprises.And sound source part 31 is multiplied by the coefficient of the volume data (velocity of sound) comprised based on note open event to the Wave data read, and generate the tone data of regulation volume level.The tone data generated exports to voicefrequency circuit 32, finally, produces the musical sound of regulation from loudspeaker 35.

Afterwards, CPU12 execution parameter communication process (step 1605).In parameter communication process (step 1605), according to the instruction of CPU12, send the data of the form of main areas and the tone color such as will edited by switch process (step 1602) and the form of subregion and pitch to music performance apparatus main body 11.In music performance apparatus main body 11, if infrared communications set 24 receives data, then CPU21 accepts data via I/F27, and is stored in RAM26 (step 310 of Fig. 3).

In the step 310 of Fig. 3, the CPU21 also execution parameter communication process of music performance apparatus main body 11.In the parameter communication process of music performance apparatus main body 11, send to musical instrument portion 19 generate based on the main areas of setting in step 305 ~ 308 and tone color and subregion and pitch and be stored in the data of in RAM26, main areas and the form of tone color and the form of subregion and pitch.

If the parameter communication process (step 1605) in musical instrument portion 19 terminates, then CPU12 performs other process, such as, performs (steps 1606) such as the renewals of image shown on the picture of display part 16.

According to the first embodiment, the position of music performance apparatus main body 11 is positioned at main areas and its position is positioned at subregion time as pronunciation timing, CPU21 utilize preserve in the form of main areas and tone color with main areas establish preserve in the form of corresponding tone color and subregion and pitch establish corresponding pitch with subregion, generate note open event.Thus, player, by operating music performance apparatus main body 11 towards the subregion of regulation in the main areas set for the tone color specified, can send desired tone color and the musical sound of pitch.

And, in the present embodiment, CPU21 based on the positional information on the summit of more than 3, using link the plane on summit carry out projecting to ground surface and the plane that obtains as bottom surface, the space that the plane becoming this bottom surface and the vertical line that extends from its summit delimited is determined as main areas.Like this, player, by specifying summit, can set the main areas of the plane based on connect Vertex.In addition, in the above-described embodiment, set as main areas the plane (quadrilateral) that number of vertices is 4, but by changing number of vertices, the main areas of any bottom shapes such as triangle can be set.

And then in the present embodiment, the positional information of CPU21 based on specified center, the positional information of other positions different from this center, be defined as subregion by centered by center, from the circular flat of other position processes.Thus, by designated centers position and other positions (through position), the two dimensional surface of circle can be set as subregion.

And, in the present embodiment, music performance apparatus main body 11 has geomagnetic sensor 22 and acceleration transducer 23, CPU21 is based on the sensor values of geomagnetic sensor 22, detect the moving direction of music performance apparatus main body 11, and based on the sensor values of acceleration transducer 23, calculate the amount of movement of music performance apparatus main body 11.According to moving direction and amount of movement, obtain the current location of music performance apparatus main body 11.Therefore, it is possible to do not use large-scale device and do not carry out complex calculations, obtain the position of music performance apparatus main body 11.

Next, the second embodiment of the present invention is described.In the first embodiment, as main areas, set the plane obtained to ground surface projection by the polygon connecting multiple summit and the determined region of vertical line extended from summit.And, as subregion, set the plane domain of the circle determined by center and radius.But the shape in region is not limited to these.

Such as, in this second embodiment, as subregion, setting connects the polygonal plane domain on multiple summit.Figure 17 is the figure of the example of the subregion setting process represented involved by the second embodiment.In this second embodiment, the process (such as, main areas setting process, tone color setting process, pitch setting process, pronunciation timing check processing etc.) beyond subregion setting process is identical with the process shown in the first embodiment.

As shown in Figure 17, CPU21 obtains the positional information (step 1701) of the music performance apparatus main body 11 that RAM26 preserves, and judges whether music performance apparatus main body 11 is positioned at certain main areas (step 1702).When being judged as "No" in step 1702, terminate subregion setting process.

When being judged as "Yes" in step 1702, CPU21 judges whether the subregion configuration switch in input part 18 is switched on (step 1703).When being judged as "Yes" in step 1703, CPU21 obtains the positional information that RAM26 preserves, and it can be used as the coordinate on summit (apex coordinate) to be stored in RAM26 (step 1704).Then, CPU21 making in RAM26, representing that the parameter M of number of vertices is from adding 1 (step 1705).In addition, identical with the first embodiment, above-mentioned parameter M is initialized to " 0 " in initialization process (step 301 of Fig. 3).Then, CPU21 judges that whether parameter M is than " 4 " large (step 1706).When being judged as "No" in step 1706, terminate subregion setting process.

In step 1706, be judged as that the "Yes" meaning refers to that 4 apex coordinates have been stored in RAM26.Therefore, when being judged as "Yes" in step 1706, CPU21 obtains the information (step 1707) of the two dimensional surface (quadrilateral) of being delimited by 4 apex coordinates.Then, the information of acquired two dimensional surface is stored in the form of subregion in RAM26 and pitch (step 1708) by CPU21.Then, the parameter M in RAM26 is initialized as " 0 " by CPU21, and subregion is set mark and be set to " 1 " (step 1709).

Like this, according to the second embodiment, the subregion as the two dimensional surface of being delimited by multiple summit (being 4 summits in the present embodiment) can be set.In each sub regions, identical with the first embodiment, can by the pitch desired by pitch setting process setting.Figure 18 is the figure that outline represents the example of the pitch of subregion and the correspondence set in the subregion setting process and pitch setting process of the music performance apparatus main body involved by present embodiment.In this example embodiment, in subregion setting process, the quadrilateral of being delimited by 4 summits is set as subregion.In figure 18, the main areas (reference marker 1800) of being delimited by projection 1810 and the vertical line that extends from its summit, 6 sub regions 180 ~ 185 of quadrilateral are exemplified respectively.The region ID of subregion 180 ~ 185 is respectively " 0 " ~ " 5 ".And, each sub regions 180 ~ 185 is assigned to the pitch of C3 ~ A3.These information are stored in the subregion of RAM26 and the form of pitch.Such as, if wave music performance apparatus main body (mark 1801) under player, the front end of this music performance apparatus main body (mark 1802) through subregion 182, then sends the musical sound of E3 pitch.

And, as main areas, also can be same with the first embodiment, obtain the circular two-dimensional plane based on center C and radius d, set this plane region that the projecting plane that obtains and the vertical line that extends from this projecting plane delimited to ground surface projection.

And then, also can be, not in accordance with obtaining center and radius to obtain the mode of the information of plane, but the information of player by making music performance apparatus main body 11 move the plane obtaining circle or ellipse along desired region in space.Below, illustrate that the track based on music performance apparatus main body 11 sets the situation of main areas by the 3rd embodiment.In the third embodiment, also set circular (or oval) main areas as the column of bottom surface.That is, in the third embodiment, player moves along desired region in space by making music performance apparatus main body 11, delimit the plane of circle or ellipse, the plane of delimiting becomes the bottom surface of the cylinder (or cylindroid) of regulation main areas to the projecting plane of ground surface.Figure 19 is the process flow diagram of the example of the main areas setting process represented involved by the 3rd embodiment.In the third embodiment, in order to set main areas, the switch portion 28 of music performance apparatus main body 11 has setting and starts switch and setting end switch.In addition, in the third embodiment, the process (such as, tone color setting process, subregion setting process, pitch setting process, pronunciation timing check processing etc.) beyond main areas setting process is identical with the process shown in the first embodiment.

As shown in Figure 19, CPU21 judges that setting starts switch and whether is switched on (step 1901).When being judged as "Yes" in step 1901, CPU21 obtains the positional information that RAM26 preserves, and it can be used as the coordinate of start position (starting point coordinate) to be stored in RAM26 (step 1902).And mark in setting is set to " 1 " (step 1903) by CPU21.

When being judged as "No" in step 1901, CPU21 judges in setting, whether mark is " 1 " (step 1904).When being judged as "Yes" in step 1904, obtain the positional information that RAM26 preserves, and it can be used as the coordinate (through position coordinates) through position to be stored in RAM26 (step 1905).In addition, step 1905 is performed repeatedly, until player connects the end switch of music performance apparatus main body 11.Therefore, in step 1905, be stored in RAM26 with being associated by through position coordinates with the execution number of times of step 1905.

Then, CPU21 judges whether end switch is switched on (step 1906).When being judged as "Yes" in step 1906, CPU21 obtains the positional information that RAM26 preserves, and it can be used as the coordinate in final position (terminal point coordinate) to be stored in RAM26 (step 1907).Then, CPU21 judge terminal point coordinate whether distance starting point coordinate be positioned at the scope (step 1908) of regulation.When being judged as "No" in step 1908, end region setting process.When being judged as "No" in step 1904,1906, end region setting process too.

When being judged as "Yes" in step 1908, based on starting point coordinate, through position coordinates, final position coordinate, obtain for determine through these coordinates ellipse or circle information (step 1909).CPU21 also can make the closed curve connecting adjacent coordinate, and obtains the circle approximate with this closed curve or ellipse.Such as, for approximate, the method that least square method etc. is known can be applied.And, CPU21 calculates the ellipse corresponding with the projecting plane that the ellipse determined in step 1909 or circle are projected to ground surface and obtained or the information of circle, and using based on the ellipse of this projection or the information of circle as the information of main areas, be saved in the form of main areas in RAM26 and tone color (step 1910).Then, mark in the setting in RAM26 is reset to " 0 " by CPU21, and main areas is set mark and be set to " 1 " (step 1911).

According to the 3rd embodiment, the plane that can set shape desired by player sets towards the projecting plane on earth's surface and from projecting plane the main areas of the column that vertically extending wall delimited.Particularly, in the third embodiment, the main areas making the track of music performance apparatus main body 11 movement such as the side of outline player can be set.In addition, subregion also can be set by the method described in the 3rd embodiment certainly.

And the setting of main areas is not limited to set based on the track of above-mentioned music performance apparatus main body 11.Such as, also can be identical with the setting of the subregion in the first embodiment, obtain the circular two-dimensional plane based on center C and radius d, set this plane region that the projecting plane that obtains and the vertical line that extends from this projecting plane delimited to ground surface projection.To this, describe later with reference to Figure 24.

Next, the 4th embodiment of the present invention is described.In the 4th embodiment, if player sets a region in main areas, then by this region segmentation for regulation number, split regional is set as subregion, and automatically distributes pitch to this each sub regions.

In the 4th embodiment, replace the subregion setting process (step 307) in Fig. 3 and pitch setting process (step 308), perform the setting process of subregion and pitch.Figure 20 is the process flow diagram of the example of the setting process representing subregion involved by the 4th embodiment and pitch.As shown in Figure 20, CPU21 obtains the positional information (step 2001) of the music performance apparatus main body 11 that RAM26 preserves, and judges whether music performance apparatus main body 11 is positioned at certain main areas (step 2002).When being judged as "No" in step 2002, terminate the setting process of subregion and pitch.

When being judged as "Yes" in step 2002, CPU21 judges whether the subregion configuration switch in input part 18 is switched on (step 2003).When being judged as "Yes" in step 2003, CPU21 obtains the positional information that RAM26 preserves, and it can be used as the coordinate on summit (apex coordinate) to be stored in RAM26 (step 2004).Then, CPU21 making in RAM26, representing that the parameter M of number of vertices is from adding 1 (step 2005).In addition, identical with the first embodiment, above-mentioned parameter M is initialized to " 0 " in initialization process (step 301 of Fig. 3).Then, CPU21 judges that whether parameter M is than " 4 " large (step 2006).When being judged as "No" in step 2006, terminate subregion setting process.

In step 2006, be judged as that the "Yes" meaning refers to that 4 apex coordinates have been stored in RAM26.Therefore, when being judged as "Yes" in step 2006, CPU21 obtains the information (step 2007) of the two dimensional surface (quadrilateral) of being delimited by 4 apex coordinates.Then, CPU21 will obtain two dimensional surface P decile, and obtain P the part planar positional information separately apex coordinate of (information) at 4.The positional information of each several part plane that this obtains by CPU21, as the information of subregion, is stored in the form (step 2008) of subregion in RAM26 and pitch.

Then, parameter p is initialized as " 0 " (step 2009) by CPU21, to pitch Note (p) of p sub regions (subregion ID=p) distribution provisions, and preserve pitch Note (p) (step 2010) with being associated with subregion ID in the form of subregion and pitch.CPU21 makes parameter p from adding 1 (step 2011), and judges whether parameter p is more than P (step 2012).When being judged as "No" in step 2012, turn back to step 2010.When being judged as "Yes" in step 2012, CPU21 makes the parameter M in RAM26 be initialized as " 0 " (step 2013).

Figure 21 is the figure that outline represents the subregion set in the subregion of music performance apparatus main body involved by present embodiment and the setting process of pitch.As shown in figure 21, by projecting plane 2110 with from the main areas (reference marker 2100) that the vertical line that summit extends delimited, two dimensional surface 2120 is set with by player.By the setting process of subregion and pitch, two dimensional surface 2120 is divided into P part planar (such as reference marker 2130,2131), and this P part planar is assigned respectively to pitch Note (p) of subregion ID and correspondence.The positional information (apex coordinate) of subregion and pitch are stored in the form of subregion and pitch with subregion ID respectively with being associated.

According to the 4th embodiment, if in main areas, player sets two dimensional surface by operation music performance apparatus main body 11, then this two dimensional surface divided and generate regulation number subregion, the positional information of the subregion of this regulation number is stored in the form of subregion and pitch, and the pitch should distributing to all subregion is also stored in the form of subregion and pitch.Therefore, the simple operations undertaken by player, terminates the setting of desired subregion.

According to the 4th embodiment, can produce showing and corresponding from different pitches hit the musical instrument of body (such as Figure 30 A) as xylophone or glockenspiel etc. in space in analog.

But, also can change the shape on the two dimensional surface of subregion 2120, more easily play to make player.Such as also can as shown in figure 30b, make polygon-shaped in the mode of surrounding player.

At above-mentioned first embodiment in the 4th embodiment, set the tone color of the musical sound that should send with being associated with main areas, set the pitch of the musical sound that should send with being associated with each sub regions.In the 5th embodiment, set first tone color suitable with tone color classification (category) with being associated with main areas, set second tone color suitable with the subcategory than the first tone color refinement with subregion with being associated.

In the 5th embodiment, performing except the second tone color setting process this point except replacing the pitch setting process of the step 308 of Fig. 3, performing the process almost identical with the first embodiment.Particularly, as the 5th embodiment, the first tone color is percussion instrument, and the second tone color is comprised in such as to step on small cymbals, snare drum, bass drum, gong, big cymbals etc. in the such classification of percussion instrument.And, in the tone color setting process of Fig. 6, confirm the connection of switch in response to tone color, send certain (such as snare drum) musical sound of the second tone color comprised in idiophonic classification.

Figure 22 is the process flow diagram of the example of the second tone color setting process represented involved by the 5th embodiment.As shown in figure 22, CPU21 judges whether subregion setting mark is " 1 " (step 2201).When being judged as "No" in step 2201, terminate the second tone color setting process.

When being judged as "Yes" in step 2201, CPU21 judges that tone color confirms whether switch is switched on (step 2202).When being judged as "Yes" in step 2202, CPU21 generates the note open event (step 2203) comprising timbre information, and this timbre information is the information based on the parameter DTN representing percussion instrument tone color.This parameter DTN is such as the tone color number for determining percussion instrument tone color uniquely.In this note open event, preset the information representing volume level or pitch.Then, generated note open event is exported (step 2204) to I/F26 by CPU21.I/F27 makes infrared communications set 24 note open event be sent with infrared signal.Infrared signal from infrared communications set 24 is received by the infrared communications set 33 in musical instrument portion 19.Thus, in musical instrument portion 19, send the idiophonic musical sound of regulation.

After step 2204, CPU21 judges to determine whether switch is switched on (step 2205).When being judged as "No" in step 2205, CPU21 makes the parameter DTN of expression tone color from adding 1 (step 2206), turns back to step 2202.When being judged as "Yes" in step 2205, the timbre information shown in parameter DTN and the information of subregion are stored in the form of subregion in RAM26 and tone color (step 2207) by CPU21 with being associated.Then, subregion is set Flag Reset as " 0 " (step 2208) by CPU21.

In the 5th embodiment, in RAM26, replace the form of subregion and pitch, and the form of subregion and tone color is set.In the form of the subregion shown in Figure 12 and pitch, replace the project of pitch and the project that arranges about idiophonic second tone color.

According to the 5th embodiment, as main areas, setting can set the region of the second tone color, in main areas, and setting subregion, and various second tone color can be distributed to these subregions.

First embodiment of the present invention ~ the 5th embodiment is illustrated, but the present invention is not limited to above-mentioned embodiment.Such as, the first embodiment and the 5th embodiment can be combined.In the embodiment involved by this combination, when being assigned with the tone color of the transformable musical instrument of the pitch such as vibraphone, xylophone by the setting process of tone color shown in Fig. 6 to main areas, and then subregion setting process (with reference to Fig. 9), performs pitch setting process (with reference to Figure 10).On the other hand, when setting idiophonic tone color by tone color setting process to main areas, and then subregion setting process (with reference to Fig. 9), performs the second tone color setting process (with reference to Figure 22).In this embodiment, after subregion setting process, CPU21 judges that the tone color set by tone color setting process (Fig. 6) is idiophonic tone color or the tone color beyond it.

Figure 23 is the example of main areas during outline represents involved by combination embodiment and subregion.In fig 23, left side represents the main areas and subregion that set according to the 4th embodiment, and right side represents according to the main areas set by the 5th embodiment and subregion.In left side, in main areas 2300, include the region 2310 of player's setting, divided further have multiple region, and divided part planar becomes subregion (reference marker 2311,2112) respectively.And, each sub regions is assigned to the pitch of regulation.

On the other hand, on right side, in main areas 2320, be set with multiple subregion (reference marker 2321,2322), and various second tone colors as idiophonic subcategory are set with to each sub regions.

When player is positioned at main areas 2300, by making music performance apparatus main body 11 be positioned on subregion, send the musical sound of the pitch being assigned to subregion with the tone color (such as vibraphone) being assigned to main areas 2300.On the other hand, when player is positioned at main areas 2320, by making music performance apparatus main body 11 be positioned on subregion, send musical sound with the second tone color being assigned to subregion.Like this, by moving in different main areas, can the performance of the different musical instrument of simulated implementation.
