E2: EG
An acronym for Envelope Generator, a block that modifies the level of the tone genera-
tor from the moment that a note is played until the sound decays to silence. The Ampli-
tude EG controls the volume level, the Pitch EG controls the pitch, and the Filter EG
controls the filter cutoff frequency.

• AMP. RATE and AMP. LEVEL (Amplitude EG settings)
The AMP. RATE parameters are time-related; they determine how long it takes for the sound
volume to change from level to level (as set in AMP. LEVEL).
The AMP. LEVEL parameters are volume-related; they determine how loud or soft the volume
changes are over time (as set in AMP. RATE).

• PITCH RATE and PITCH LEVEL (Pitch EG settings)
The PITCH RATE parameters are time-related; they determine how long it takes for the
sound's pitch to change from level to level (as set in PITCH LEVEL).
The PITCH LEVEL parameters are pitch-related; they determine how much the sound devi-
ates from normal pitch over time (as set in PITCH RATE).

* Higher rate values produce faster variation.
Sets the rate of variation from key-on to the maximum attack level.
Set the rate of variation between the maximum attack level and the levels set by the
AMP LEVEL DECAY1 and DECAY2 parameters and the final level, respectively.
Sets the rate of variation from the level at key-release to level 0 when SUSTAIN is off.
Sets the rate of variation from the level at key-release to level 0 when SUSTAIN is on.
Sets the initial level of the envelope.
Set the levels following the elapsed time of DECAY 1 and DECAY 2, respectively.
Set the rate of variation between the initial pitch envelope level and the levels set by
the PITCH LEVEL DECAY1, DECAY2, and DECAY3 parameters, respectively.
Sets the rate of variation from the level at key-release to the level set by the PITCH
LEVEL RELEASE parameter.
Sets the initial pitch of the envelope.
Set the amounts of pitch change following the elapsed time of DECAY 1 and DECAY
2, respectively.
Sets the final pitch of the envelope; the pitch goes to this point (at the RELEASE rate)
after the key is released.
