1-2-9 Amplitude EG (Envelope Generator)
This lets you control the transition in Amplitude from the moment the sound starts until the
moment the sound stops. You can create a custom Amplitude EG by setting parameters as
illustrated below. When you press a key on the keyboard, the volume will change according to
these EG settings.

Attack Time Determines how quickly the sound reaches its maximum level after the key
is pressed.
Decay 1 Time Determines how fast the envelope falls from the Attack Level to the
Decay 1 Level.
Decay 2 Time Determines how fast the envelope falls from the Decay 1 Level to the
Decay 2 Level (sustain level).
Release Time Determines how quickly the sound decays to silence after the key is
released.
Initial Level Determines the initial level at the moment the key is pressed.
Attack Level Determines the maximum level which the envelope reaches after a key is
pressed.
Decay 1 Level Determines the level which the envelope reaches from the Attack Level
after the Decay 1 Time elapses.
Decay 2 Level Determines the level which will be maintained while a note is held.
