[TVA
EG
Break
Points]
By
setting the Break
point
of
an envelope
curve,
wave
data can be
read
(played
back)
in different
volumes. For
instance, the attack of a
sound
can be purposely
delayed, or a decaying
effect
can be
added
to
a loop.
However,
the
volume
of the
sampled sound
is
the
maximum,
therefore,
it is
not possible
to
make
the attack quicker than
the
sampled
waveform,
or increase the
volume,
or sustain a
one—
shot sound.
Up
to
eight break
points (rates
and
levels)
can be
set for
making
an
envelope curve
that controls the cutoff point
of the
Lowpass
filter.

L-
LEVEL
R-RATE
Sustain Point
Rate
[1
to
127]
This
is
a
slide
from
a
break
point
to
the next
one.
Higher
values
make
steeper
slopes.
Level
[0 to 127]
This
sets the level of a
break
point.
SUS
(Sustain
Point)
[1
to 7]
This
sets
the
level to be sustained
until the
key
is
released.
*lt
is
not
possible to set
this after the end
point.
END
(End
Point)
[2 to 8]
This
is
the
end
of
the curve.
*lt
is
not
possible to set
this
before the
sustain
point.
*The
Rate
before the Sustain
point
and End
point actually
draws
an
exponential curve.
