Playing Songs

Your digital piano can play built-in Preset Songs, User Songs that you have recorded, and commercially available

songs. These songs can be in one of two different formats—MIDI or audio.

Song Category list

*: Shown only when a USB flash drive has been plugged into the instrument.

**: Shown

only when the USB flash drive contains data of the corresponding format.

User Songs and Import Songs

The term User Song is used to refer to songs recorded using

the instrument itself; those created in any other way are

referred to as Import Songs. Songs contained within a folder

named USER FILES on a USB flash drive are designated as

User Songs and handled in the same way. Songs located

outside this folder are handled as Import Songs. If the USB

flash drive plugged into the instrument contains no USER

FILES folder, one will be created automatically when you

record a song to that drive. The recorded User Song will

then be saved in that folder.

Supported song data formats

Standard MIDI File formats 0 and 1

Standard MIDI File (SMF) formats are the most commonly

used MIDI formats for storing sequence data. SMF format 0

is used for MIDI songs recorded using this instrument.

Waveform Audio File format

Identified by a .wav file extension, Waveform Audio File For-

mat (WAV) is one of the most common formats used by

computers to record audio data. Your digital piano supports

the playback and recording of 44.1-kHz, 16-bit, stereo .wav

files.

Select the correct song category using

the [SELECT] button.

You can cycle through the available categories

(Aud, Sng, USr, and PrE) with each press of

the button; however, Aud and Sng are shown

only when a USB flash drive has been plugged

into the instrument. If you wish to play an Import

Song (001 to 999), be sure to choose the corre-

sponding category.

Use the [-/NO] and [+/YES] buttons to

select a song number, “rnd” (random),

or “ALL”.

If necessary, press the [-/NO] and [+/YES] buttons

together to show Import Songs (001 to 999).

MIDI and audio songs

MIDI songs contain data created by recording the actions of playing and releasing keys—in other words, they do not con-

tain actual audio. This data is similar to sheet music in that it indicates the keys that should be played, as well as when and

how hard they should be played, in order to reproduce a specific piece of music. Using this data, your digital piano’s tone

generator can recreate the sound of the recorded performance. MIDI songs are smaller than audio songs because they

contain less data; in addition, they also allow you to change the Voice used for playback and a number of other parameters.

In contrast, audio songs contain actual recordings of the sound of a performance, and they store audio data in much the

same way as a cassette tape or digital voice recorder. Audio songs can be played back on portable music players and

many other types of device, making it easy for you to let others hear what you have played.
