Playing and Practicing Songs This instrument can play Preset Songs, Songs you recorded on this instrument, or commercially available Songs. In addition to listening to these Songs, you can play the keyboard as the Song plays back. There are two kinds of Songs that can be recorded and played back on this instrument: MIDI Songs and Audio Songs. • MIDI Song MIDI A MIDI Song is comprised of your keyboard performance information and is not a recording of the actual sound itself. The performance information refers to which keys are played, at what timing, and at what strength-just as in a musical score. Based on the recorded performance information, the tone generator outputs the corresponding sound. A MIDI Song uses a small amount of data capacity in comparison to an Audio song, and allows you to easily change aspects of the sound, such as Voices used, etc. • Audio Song Audio An Audio Song is a recording of the performed sound itself. This data is recorded in the same way as that used with voice recorders, etc. This data can be played with a portable music player, etc., allowing you to easily let other people hear your performance. Availability of functions differs between MIDI Songs and Audio Songs. In this chapter, the following icons indicate whether or not the explanation applies to MIDI Songs or Audio Songs individually.
