PURPOSE:To enjoy music with various timbres by sensing expiration pressure by a diffusion type semiconductor pressure sensor and generating a signal which is specified and outputted by a musical interval input means. CONSTITUTION:This instrument is equipped with the diffusion type semiconductor pressure sensor module 12 for expiration. Therefore, while the instrument is played, the pressure sensor module is controlled and an output corresponding to the intensity, energy, etc., of the expiration is sent from an A/D converter 13 to a CPU 14, and inputted from a musical interval input means 15 to the CPU, and its output is converted into MIDI (Musical Instrument Digital Interface) data, which is outputted as an audio tone from a sound source module 16, thereby playing music by the instrument. Thus, expiration pressure information and musical interval information specified by a musical interval input means are outputted as the audio tone to enable real and effective performance. |
