When the Traveler
is used as a pre-set,
one
touch
will permit the player to find a
tone
color
spontaneously, once he is
familiar with the ope-
ration of the two levers.
When the Traveler is
used dynamically, a
fine back and
forth movem-
ent will create a
tremolo. A wider
left-right
sweep
will give rise to
a curved tone
which,
when properly timed
to the keyboard action,
can create a wah or a
muting effect.
•BRIGHT
For adding
traveler resonance
effect.
The
posi-
tion l provides
stronger resonance effect
than
the position
2. Explore the variations and
the
changes of tone color by setting
the knobs at
various positions.
•LFO
Low Frequency Oscillator. For
adding repeat,
howling
and
other effects in
order
to
change tone.
Set the BRIGHT
switch at position 1 hold
the
upper and the
lower TRAVELER knobs
together
with the left
hand, and, playing the key
board,
move
them right and
left between
the 4 and 6
positions.
The above
effects can
automatically
be
produced using the LFO
switch.
Set both
TRAVELER knobs at
position
5,
set the
LFO
switch at position 1,
and turn to adjust
the upper
left LFO knob to
the cycle
obtained by
handling
the
TRAVELER knobs
manually. A similar
effect
will then be
produced
automatically. The
LFO 2
provides
the same
effect as is
obtained by irioving
the knob
over a large
distance. Test the
effect,
changing the
position of
the TRAVELER,
the
BRIGHT, the
LFO
SPEED, the VCO
I OCTA-
VE, etc. in
various ways.
•EXPAND
Switch for
connecting the
ENVELOPE
GENE-
RATOR
to the VCF.

^ENVELOPE
GENERATOR".)

the
position of the
ATTACK TIME knob

•SINGING
LEVEL
While playing the
instrument, move the
position
of the
SINGING
LEVEL
slowly from 8 to
0,
the
sustaining power of
sound will then
be gra-
dually lessened.
Try this out in.
various
ways
in combination
with the
ATTACK
TIME.
•
SUSTAIN
TIME
For varying
the sound
duration after
removing a
finger from a
key.
