The Low Cost Electronic Organ Tone Color Study

The electronic organ is the outcome in the technique development of electronics science. Technically fly to soon develop along with th e electronics, electronic organ also at constantly the renewal changegeneration. Be particularly numerical technique, large scale integra tion and the calculator technical height development, make the electr onic organ not only outruns piano, organ, violin... etc. on the sound area traditional joy sound, and can also imitate the tone color of va rious traditional musical instrument, can also produce various stereosets which specially even is a nature to basically have no. Such as:Sound,cosmos sound... etc. Especially being automatically accompany ing aspect is especiallya more traditional musical instrument to can' t compare to. Make use of the automatic rhythm, automatic bass accomp any, the automatic chords accompany etc. give musical performance fun ction, a person give musical performance, can acquire give musical pe rformance of a small scaled music band effect. Moreover, the electron ic organ category is numerous, the physical volume is small, give mus ical performance to take convenience, the price is opposite to say ch eaper. So deeply be subjected to like of large music fancier.The electronic organ is electronics science and musical instrumen t to make the outcome that the technique combine together. The electr onic organ differs from general electronics musical instrument. The g eneral electricity musical instrument was just traditional musical in strument to up increase to spread a feeling machine, enlarger etc. el ectric circuit, such as:Give or get an electric shock the Ji it, elec tricity shell a department etc.. The electronic organ is an applied mo dern electronics to flap to concuss technique and modern to control atechnical electricity to flap to concuss musical instrument. The bas ic differentiation of electronic organ and traditional musical instru ment lies in a sound source a dissimilarity. The sound source of trad itional musical instrument from machine vibration output of, such as:The vibration of Xian, the vibration of air pillar, the vibration ofthe film etc. But the sound source of electronic organ come from an electricity to flap to concuss.After adopting a calculator technique in the electronic organ, th e electronic organ took place basic sex variety. Main performance at:The first, the lifelike degree of the mimicry traditional musical in strument consumedly raised; the second, the electric circuit is more simple, the component use is little and make function price the ratioraised; The third. Increased credibility, stability, prolonged servi ce life; the fourth enriched give musical performance of electronic o rgan function. Because of the calculator technical application, just make electronic organ this musical instrument is welcome by large con sumer.CPU can be treated as the heart of electronic organ, can also say to be the conductor department of electronic organ. Mainly be respon sible for management and function to assign. At this time while press ing to move some one keyboard or function switch, the CPU knows and c arries out what mission, and chase this mission according to at that time circumstance, reasonably assign to complete for some one sectio n.In the electronic organ say that is a CPU, usually still include ROM, RAM, I/O, count a machine etc. part. It mainly works BE: The exp ortation scans a scan of keyboard and function switch signal; Scan ke yboard and function switch sends back signal with the assurance which key or the switch was press to move; According to the circumstance f or scan to music wave form occurrence the machine settle into the dat a; Produce the rhythm triggers pulse and automatically fights joy to trigger pulse.
