●E2: EG

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

Indicates the EG settings as a diagram.

Resets the currently selected EG parameters to their most basic settings.

RELEASE LEVEL

TIME

* Higher rate values produce faster variation.

• 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).

AMP.RATE

ATTACK

Sets the rate of variation from key-on to the maximum attack level.

 

DECAY1

Set the rate of variation between the maximum attack level and the levels set by the

 

DECAY2

AMP LEVEL DECAY1 and DECAY2 parameters and the final level, respectively.

 

DECAY3

 

 

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

Set the levels following the elapsed time of DECAY 1 and DECAY 2, respectively.

 

DECAY2

 

• 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 deviates from normal pitch over time (as set in PITCH RATE).

PITCH RATE

DECAY1

Set the rate of variation between the initial pitch envelope level and the levels set by

 

DECAY2

the PITCH LEVEL DECAY1, DECAY2, and DECAY3 parameters, respectively.

 

DECAY3

 

 

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

Set the amounts of pitch change following the elapsed time of DECAY 1 and DECAY

 

DECAY2

2, respectively.

 

DECAY3

 

 

RELEASE

Sets the final pitch of the envelope; the pitch goes to this point (at the RELEASE rate)

 

 

after the key is released.
