MEMORY
When this button is on (LED on), the accompani-
ment continues to play after releasing the left
hand from the keyboard. When off, releasing your
left hand causes the accompaniment to stop.
LOWER MEMORY
If this is on (LED on), the notes of the track as-
signed to the left hand (Lower) are held even if
the left hand is taken away from the keys.
The Lower Memory function is useful for holding
on ‘background’ sounds without having to use a
Damper pedal (which may be of more use with
the Upper sounds).
When off, releasing your left hand will cause the
Lower sound to stop playing.
TEMPO LOCK
If Tempo Lock is off, when a Style or a Preset is
selected the tempo changes. If the function is
on, the tempo will not change.
FADE IN/OUT
FADE IN/OUT fades the accompaniment with a
gradual increase or decrease of volume.
Press the button before starting the accompani-
ment. The Style track volumes are instantly set
to zero. Use either START/STOP or KEY START
to start the accompaniment. After the start, the
accompaniment track volumes gradually increase
and reach their programmed peak after a 2 meas-
ure (bar) cycle.
Press FADE IN/OUT while the accompaniment
is running; all the track volumes gradually de-
crease and the accompaniment automatically
stops at the end of the Fade Out cycle.
During the Fade cycle, the relative LED flashes.
MIXER LOCK
A Preset also memorizes the track volumes. If
MIXER LOCK is off, when a Style or Preset is
selected the track volumes change too. If it is
on, all the volumes of the tracks assigned to the
keyboard and accompaniment rest unchanged.
BASS FOLLOW
If BASS FOLLOW is on, the bass part of the auto
accompaniment of the current Style plays accord-
ing to the lowest note of the current chord. If you
play a different inversion of the same chord, the
lowest note also changes resulting in a different
bass note being played.
If off, the bass will follow the original programmed
pattern of the Style.
Bass Follow permits real time changes to the oth-
erwise fixed bass pattern of a Style, by playing
different chord inversions.
