When you press a key on the keyboard, the Cutoff Frequency will change according to these
EG settings.

FEG Hold Time Determines the time between the moment you press a key on the
keyboard and the moment the envelope starts to rise.
FEG Attack Time Determines the speed of attack from the initial Cutoff Frequency (at Hold
Level) to the maximum level of the Part after the Hold Time has elapsed.
FEG Decay 1 Time Determines how fast the envelope falls from the maximum Cutoff
Frequency (at Attack Level) to the Cutoff Frequency specified as the
Decay 1 Level.
FEG Decay 2 Time Determines how fast the envelope falls from the Cutoff Frequency
specified as the Decay 1 Level to the Cutoff Frequency specified as the
Decay 2 Level.
FEG Release Time Determines how fast the envelope falls from the Cutoff Frequency
specified as the Decay 2 Level to the Cutoff Frequency specified as the
Release Level when the note is released.
FEG Hold Level Determines the initial Cutoff Frequency at the moment the key is pressed.
FEG Attack Level Determines the maximum Cutoff Frequency which the envelope reaches
after a key is pressed.
