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

Resets the currently selected
EG parameters to their most
basic settings.
* Higher rate values produce faster variation.
