Applying various effects to the sound
■
Changing the sound’s volume (ENVELOPE)
The volume continues to change from the time a key is pressed to when it is released.
A: Attack Time: The time from when the keyboard is pressed until the maximum
tonal change is reached.
D: Delay Time: The time from when the maximum tonal change is reached until the
Sustain Level is reached.
S: Sustain level: Volume that is sustained while you hold down the key
R: Release Time: The time from when the keyboard is released until the sound
disappears.
Use the ENVELOPE 3 knobs to change the A, D, and R times.
* Each tone has its own Sustain level, which cannot be modified.

The “envelope” is the curve
that shows how the volume
of an instrument changes
from the beginning of a
note to its end. Each
musical instrument has a
distinctive type of
envelope, but this can
change depending on how
the instrument is played,
and is an important factor
in the character of the
sound. For example, when
a trumpet is blown strongly
it produces a piercing
sound with a rapid attack,
b
ut when blown softly it
produces a gentler and
more muted attack.
