Mobile alignment calculating section 202 calculates the predetermined vertically extending coordinate mobile alignment mt of a side (or an end) that shows importation 9 from the coordinate of required keyswitch 100 to matrix.
Fig. 4 shows the figure of the relation between the required keyswitch coordinate 100 and mobile alignment in so-called beating (bouncing) pattern.
As shown in Figure 4, mobile alignment mt is the route that coordinate progressively moves with predetermined time interval, vertically downward or upwards (along Y direction) to first precalculated position of matrix demonstration importation 9 (for example from the selected coordinate of the keyswitch 100 of pushing a hope by the user (below be called " selected coordinate "), the lower end), and when (for example arriving first precalculated position, the lower end) coordinate is selected in (along Y direction) " rebound " up or down vertically of coordinate time, coordinate.In addition, according to mobile alignment mt, coordinate selected the going bail for of rebound once more, and move downward vertically.Promptly, mobile alignment mt is a kind of coordinate motion track, along this track, coordinate shows between the lower end coordinate (as selected coordinate) of importation 9 reciprocal at the selected coordinate (as the starting point of route) of user's press of key switch 100 and matrix with identical X coordinate.
Select according to mobile alignment mt that calculates and default coordinate translational speed and the keyswitch 100 that responds the user, mobile alignment calculating section 202 sequentially provides to display process part 203 and pushes or selected keyswitch 100 and matrix show the coordinate of each keyswitch 100 between the lower end of importation 9.In addition, mobile alignment calculating section 202 provides information to playing processing section 201, and described information has been indicated the time of the lower end of lighting coordinate (position) arrival matrix demonstration importation 9 on the mobile alignment mt that is calculated and lighted the time that coordinate arrives the coordinate of selected switch 100.
Then, the time that 201 responses of performance processing section are notified carries out musical sound and produces processing, wherein play processing section 201 with reference to note number table T, number with the corresponding note numbering of identification and detected coordinate and to the note that generater of musical tone 6 notices are discerned.Therefore, generater of musical tone 6 utilizes the tone color of Set For Current, produces and user's press of key switch 100 corresponding sound signals.That is, in " beating " pattern, the time point place that the coordinate of generater of musical tone 6 on mobile alignment mt is consistent with the lower end coordinate of matrix importation 9 carries out with selected keyswitch 100 corresponding musical sounds and produces processing.
For each selected keyswitch, calculating and the musical sound that can carry out this mobile alignment mt concurrently produce processing.That is,, produce processing at calculating and the musical sound being scheduled to regularly carry out mobile alignment mt in the place for each selected keyswitch 100.In this case, can identical coordinate translational speed or different coordinate translational speeds be set at each mobile alignment that is calculated.
Therefore, from the musical sound of generater of musical tone 6 output be give in advance each selected keyswitch 100 and and the lower end of each selected button 100 and importation 9 between the combination of the musical sound that produces the corresponding musical sound generation cycle of distance, musical sound randomness according to this array output is very strong, has lower correlativity each other.As a result, the musical sound from generater of musical tone 6 outputs has very high dirigibility, originality and degree of freedom.
Fig. 5 shows the concept map that shows the luminous or illuminating state of importation 9 at following time point place matrix: when selecting any one keyswitch 100 (Fig. 5 (A)), when moving coordinate moves along the mobile alignment mt from selected keyswitch 100 to matrix demonstration importation 9 (B), when moving coordinate arrives the lower end of matrix demonstration importation 9 (C), and when moving coordinate moves along the mobile alignment mt from matrix demonstration importation 9 to selected keyswitch 100.
In display process, display process part 203 utilizes higher luminance brightness sequentially to light and the keyswitch 100 corresponding luminescence display units that are positioned on the mobile alignment mt according to the timing and the coordinate that are provided by mobile alignment calculating section 202.Shown in (A) among Fig. 5,, light the corresponding luminescence display unit of mtLED (13,8) with higher luminance brightness in case the user selects mtSW (13,8) keyswitch 100.Then, moving coordinate sequentially moves down according to given timing, therefore shown in Fig. 5 (B), with higher luminance brightness light mtLED (13, luminescence display unit Y1).In case moving coordinate arrives the lower end that matrix shows importation 9, shown in Fig. 5 (C), light luminescence display unit with lower end keyswitch 100 corresponding mtLED (13,1) with higher luminance brightness.Then, moving coordinate sequentially moves up according to given timing, therefore shown in Fig. 5 (D), with higher luminance brightness light mtLED (13, luminescence display unit Y2).In this manner, display process part 203 is sequentially lighted the luminescence display unit 110 that is positioned on the mobile alignment mt, makes moving coordinate along mobile alignment mt reciprocal (reciprocate) simultaneously.Therefore, the user seems to move consistently as sharing the same light, and beats between the lower end of selected keyswitch 100 and importation 9 simultaneously.
