■ Echo Types
When one of the Echo Types is selected, the corresponding effect (echo, tremolo, trill) is applied to the
note played in the right-hand section of the keyboard in time with the currently set tempo, regardless of the
[ACMP] and the LEFT part on/off status. Keep in mind that Trill works when you hold down two notes on
the keyboard simultaneously (last two notes if more than two notes are held), and it plays those notes
alternately.

VOLUME This parameter is available for all types with the exception of "Multi
Assign." It determines the level of the harmony/echo notes generated by
the Harmony/Echo effect.
SPEED This parameter is only available when Echo, Tremolo, or Trill is selected
in Type above. It determines the speed of the Echo, Tremolo, and Trill
effects.
ASSIGN This parameter is available for all types with the exception of "Multi
Assign." This lets you determine the keyboard part via which the har-
mony/echo notes will be sounded.
CHORD NOTE This parameter is available when one of the Harmony Types is selected.
ONLY When this is set to "ON," the Harmony effect is applied only to the note
(played in the right-hand section of the keyboard) that belongs to a chord
played in the chord section of the keyboard.
TOUCH LIMIT This parameter is available for all types with the exception of "Multi
Assign." It determines the lowest velocity value at which the harmony
note will sound. This allows you to selectively apply the harmony by your
playing strength, letting you create harmony accents in the melody. The
harmony effect is applied when you play the key strongly (above the set
value).
