Knob B: RELEASE
Adjusts the Release Time (the amount of time it takes
for the sound to decay to silence after a key is
released). Turning the Knob to the right will increase
the Release Time, thus make a longer sustain.

STYLE FILTER
Same as “
c
FILTER.” These effects are applied only
to Style or Tabla/Tanpura playback.
The chart below lists some interesting ways to use the various effects that can be assigned to the knobs.
Some Ideas for Using the Knobs
• These effects are applied only to the Main/Dual Voices played
on the keyboard.

TABLA/TANPURA
Knob A adjusts the volume balance between the sounds of Tabla 1 (having the
lower sound) and Tabla 2 (having the higher sound of Tabla or Mridangam).
Knob B adjusts the volume balance between the sounds of the Tabla (assigned to
the [TABLA 1] and [TABLA 2] buttons) and Tanpura (assigned to the [TAN-
PURA 1]–[TANPURA 4] buttons). Play with these Knobs as the patterns loop,
sing along if you wish, and create your own performance.
x
TABLA/TANPURA
Knob A adjusts the tempo of Tabla/Tanpura playback. Setting to the minimum
left-most position results in half the default tempo, while setting to the maxi-
mum right-most position results in double the default tempo. The center position
corresponds to the default tempo. Note that the tempo cannot exceed the range
(11–280), and that the tempo of the Tanpura patterns will not change even if you
rotate Knob A. Knob B raises or lowers the pitch of the Tabla/Tanpura sound in
semitones. Regarding the Tabla, only the higher sound (assigned to the [2] but-
ton) will be transposed. Rotating the knob leftward lowers the pitch while rotat-
ing the knob rightward raises the pitch.
Use these knobs to set the desired tempo and key, sing along if you wish, and
create your own performance!
c
FILTER
Select a synth-type lead or pad voice (see the Voice List; page 61). Turn Knob B
all the way up and operate Knob A while playing for some spacey, floating
1980’s effects.
v
EFFECT
Select a voice that sounds as though it already has reverb and chorus effects
applied, and turn Knob A and Knob B all the way down to hear the “direct”
sound of the voice. You can then turn the Knob A and Knob B settings up to add
extra impact and richness to the voice.
b
EG
Select a piano voice, and turn Knob B all the way up and Knob A to about the 3
o’clock position. This should give you a majestic, organ-like sound. The attack
time is quite long so play the keys and hold them to let the sound come in fully.
Ideal for slow pieces.
n
STYLE FILTER
Select style 67, Euro Trance. Turn accompaniment on and start style playback
(page 22). Set Knob B to about 3 o’clock, and Knob A to about 8 o’clock. The
overall sound of the style should be a bit muffled, with the drums emphasized
for solid rhythmic impact.
