— The Secret Of the performance assistant technology —
How It Creates Music From Random Notes
When you use the Chord type, the performance assistant technology reads the chord data from the song and only
assigns notes that will "work" at that moment to the keyboard. In the Melody type it reads the song's melody data and
assigns the appropriate note(s) to the key(s) you play, so you can play the melody by playing any keys. Going back to
the Chord type, since the chords of a song are constantly changing, different notes and chords will be produced even if
you repeatedly play the same keys.
Chord tones and
other usable notes
are assigned to the
keyboard.
● Songs That Can Be Used With the performance assistant technology
When the Chord type is selected the performance assistant technology can only be used with songs that include chord
data. In the same way, when the Melody type is selected the performance assistant technology will only work with
songs that include melody data. In order to find out if a song includes the required data, first select the song and then
press the [SCORE] button. If chords appear on the display (page 19) when you press the [SCORE] button you can use
the Chord type. If the melody appears on the display (page 19) when you press the [SCORE] button you can use the
melody type.
● External Songs and the performance assistant technology
In addition to the instrument's internal songs, the 70 songs provided on the Accessory CD-ROM (page 84) can be
used with the performance assistant technology. A list of the MIDI songs included on the Accessory CD-ROM is pro-
vided on page 103.
Songs downloaded from the Internet can also be used with the performance assistant technology as long as they
include the required chord and/or melody data. Transfer song files you want to use from your computer to the instru-
ment's flash memory or an optional SmartMedia memory card (page 82).
