As shown in the illustration above, in an electronic instrument the sampled note 
(previously recorded note) stored in the tone generator section (electronic circuit) is 
played based on information received from the keyboard, and output through the 
speakers. 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 
Electone keyboard. Unlike an acoustic instrument that puts out a resonated note, the 
electronic instrument puts out information from the keyboard such as “with what 
Voice,” “with which key,” “about how strong,” “when was it pressed” and “when was it 
released.” Then each piece of information is changed into a number value and sent to 
the tone generator. Using these numbers as a basis, the tone generator plays the stored 
sampled note.
Example of Keyboard Information
As described above, your keyboard performance and panel operations such as Voice 
selection are handled as MIDI events. All rhythm-related data—including rhythm 
patterns, auto accompaniment patterns, Rhythm Sequences, etc.—also consist of 
MIDI messages.
MIDI (Musical Instrument Digital Interface) allows electronic musical instruments to 
communicate with each other, by sending and receiving compatible Note, Control 
Change, Program Change and various other types of MIDI data, or messages.
