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, but when blown softly it produces a gentler and more muted attack.
