SINGLE TOUCH PLAY
The SINGLE TOUCH PLAY button recalls all the
memorized parameters associated to the ROM
Styles, including the sounds assigned to the key-
board sections.
If the EASY PLAY and MEMORY buttons are off,
pressing SINGLE TOUCH PLAY activates both
buttons. Activating SINGLE TOUCH PLAY also
turns on KEY START.
If SINGLE TOUCH PLAY is off, you can select
STYLES from the STYLES Groups without
changing the keyboard sounds.
If you select Presets from the PROGRAMMABLE
PRESETS, the SINGLE TOUCH PLAY button
deactivates automatically.
Single Touch Play / Harmony
HARMONY
Harmony can orchestrate your Style playing,
making simple one-note melodies sound as if they
are being played by a full orchestra. This button
is associated to the Styles and Song/Styles only.
Songs cannot exploit this function.
Important: Harmony operates only when the
Easy Play button is on and when the keyboard
mode is set to SPLIT.
On/Off
This button enables (LED on) or disables (LED
off) the current Harmony Type selected in the Har-
mony Type options.
Harmony Type
HARMONY TYPE gains access to the 8 Harmony
options. The structure of the automatic harmony
is based on the current Harmony Type setting
and operates in two different ways:
A: according to the note (or chord) played
below the Split Point with Arrange On/Off
selected.
B: regardless of the note played or not played
below the Split Point.
Type A:
Close: The notes played on the left hand are
added to the melody note exactly as played. The
harmonizing chord is a closed (or tight) position
(notes fall within the same octave).
Open 1: same as close but with an open chord
(notes spread over 2 octaves).
Open 2: similar to Open 1 but with the notes
played on the left hand randomly assigned to the
right .
Block: transforms the melody note into a full four
or five note chord, each note in perfect harmony.
