<P>PROBLEM TO BE SOLVED: To control generated musical sound and a lighting state of an LED by shaking a device. <P>SOLUTION: A number key assigner 22 detects an operation of a number key and notifies a MIDI control module 24. The MIDI control module 24 outputs a MIDI message for generating sound pitch or musical sound with instrumental timbre corresponding to the key to a sound source 11. A three-dimensional acceleration detection part 21 detects an acceleration in three-dimensional arbitrary direction based on an input signal from a triaxial acceleration sensor 14 and notifies the MIDI control module 24. The MIDI control module 24 generates the MIDI message for controlling musical sound volume, pitch, cutoff frequency or the like corresponding to the acceleration and transmits it to the sound source 11, so as to control generated musical sound. Also, an LED 16 lights or flickers with a luminous color assigned to the number key, and the luminous mode is changed corresponding to the acceleration. <P>COPYRIGHT: (C)2008,JPO&INPIT |
