" 51 EZ-250i Owner's Manual 53 MIDI Functions Nearly all of the electronic musical instruments made today-particularly synthesizers, sequencers and computer music related devices-use MIDI. MIDI is a worldwide standard that allows these devices to send and receive performance and setting data. Naturally, this instrument lets you send your keyboard performance as MIDI data, as well as that of the styles and panel settings. The potential MIDI holds for your live performance and music creation/production is enormous-simply by connecting this instrument to a computer and transmitting MIDI data. In this section, you'll learn the basics of MIDI and the particular MIDI functions of this instrument. What Is MIDI? No doubt you have heard the terms "acoustic instrument" and "digital instrument. " In the world today, these are the two main categories of instruments. Let's consider an acoustic piano and a classical guitar as representative acoustic instruments. With the piano, you strike a key, and a hammer inside hits some strings and plays a note. With the guitar, you directly pluck a string and the note sounds. But how does a digital instrument go about playing a note? Acoustic guitar note production Digital instrument note production L Sampling Note Tone Generator (Electronic circuit) Sampling Note R Playing the keyboard Pluck a string and the body resonates the sound. Based on playing information from the keyboard, a sampling note stored in the tone generator is played through the speakers. As shown in the illustration above, in an electronic instrument the sampling note (previously recorded note) stored in the tone generator section (electronic circuit) is played based on information received from the keyboard. So then what is the information from the keyboard that becomes the basis for note production?For example, let's say you play a "C" quarter note using the grand piano sound on the instrument.
