-k
Level
When
creating a single
sound program by using several Tones,
you can change
the
volume
balance to
emphasize
certain parts
of the sound.
We
suggest
that
you
set the
level to the
maximum
value (127)
when
using only
one Tone,
or
when
you want
several
Tones
to
sound
at
the
same volume.
You
can
also adjust the
volume
in
realtime
as
you
play by using the appropriately assigned
Parameter
Slider.
^
Level
Key
Follow/Velocity
Curve
This allows you
to
change
the
level by key
position
or velocity.
We
suggest
that
you
set the
key follow
to a
value
between
-
10 and
-
30
to
maintain a
relatively
even
balance. This
is
because higher frequency sounds
are
perceived
as
being
louder,
even though
the actual
volume
is
the
same throughout
the
keyboard range. Also,
when
setting the
key follow parameters of
the
two Tones
to
100 and
-
100, the
timbre of the
sound changes
as
you
play
from
the
lower
range of the
keys
to the higher range.
For
recreation
of musical instruments
whose
sound
quality
changes greatly
depending on
the
playing
strength and.
sound
range,
you
can
program
a
composite sound
that
changes
greatly
by
using different
Tones and assigning
them
to different
key range or velocity zones.
*
Pan
Offset/Key Follow
Pan
offset
determines
the basic stereo position
of
the
Tone, and key follow
is
used
to set
how
the
sound
moves
in
the
stereo position in
response to key position.
When
fixing the stereo
image
of the Tone,
first
set
the
key follow value
to 0,
then decide the stereo position.
When
creating the
sounds of an ensemble, you can achieve
a
widely dispersed sonic
effect in
which the individual
instruments or
Tones
are scattered
left
and
right
over
the stereo
field.
The
technique
is
also effective for piano
sounds; set the offset
value
to
and
the
key follow
to
100
to
have
the
notes of the
piano spread
across the stereo
field
according
to
key position.
ic
Tone
Delay
This applies a delay
to
the
start
of the
Tone
after
a
key
is
pressed.
You
can
create an
echo
effect
by
setting different
delay times for the
various
Tones. Since
this
parameter
is
independent of the
delay
effect,
the original
and delayed
sounds can be completely
different
sounds.
You
can
also
use
this
function to
produce arpeggios with
the
touch of
a
single
key by
assigning different pitch settings for
each Tone.
-k
Envelope
Set
the level
so
that
it
gradually decreases
for
sound programs
like
pianos, bells
or
guitars,
whose volume
decays
fairly
quickly over time.
The L3
parameter should be
set to
a relatively
high value
for the
sound programs which
have
a fairly steady,
continuous sound, such
as violin or
clarinet.
However, even though sounds
like
one-shot
waveforms
or
rhythm
waveforms
are
pre-programmed with
their
own
level
changes, the
envelope
effect
is
added
to
this original
envelope.
