AMP AEG (Amplitude Envelope
Generator)
The Amplitude Envelope Generator controls the
change in amplitude from the moment a note in
pressed on the keyboard to the moment it is released.
By setting the Attack Time, Decay 1 Time and the
Decay 1/2 Level, you can determine how fast the
sound reaches its peak amplitude and how it fades
out. Parameters can be set for each Drum Key.
This parameter is only available if the Type parameter
in the OSC Wave screen is set to “wave.”
■Attack (Attack Time)
Set the Attack Time.
❏Settings: 0 ~ 127
■Decay1 (Decay 1 Time)
Set the Decay Time.
❏Settings: 0 ~ 127
■Level (Decay 1 Level)
Set the Decay 1 Level.
❏Settings: 0 ~ 127
■Decay2 (Decay 2 Time)
Set the Decay 2 Time.
If you select “hold,” the level amplitude will be held
until you release the note.
❏Settings: 0 ~ 126, hold
AMP VelSens (Amplitude Velocity
Sensitivity)
You can define how the amplitude (output level) varies
according to the velocity of the received notes.
■Level
Set the velocity sensitivity of the Amplitude Envelope
Generator’s output level. Positive settings will cause the
output level to rise the harder you play the keyboard
and, conversely, negative values will cause it to fall.
❏Settings: -64 ~ 0 ~ +63

Amplitude Envelope Generator Settings
The Amplitude Envelope Generator has three Time
parameters and one Level parameter. These govern the
transitions between output levels for the duration of a
note. The Attack Time is the time taken for the sound to
reach its peak output level from the moment a note is
played on the keyboard. The Decay 1/2 Time and the
Decay 1 Level parameters are used to set the behavior of
the remainder (between the sound’s peak output level and
the point at which it fades to zero). Furthermore, you can
set these parameters to be sensitive to note velocity.
The Attack Level is fixed at its maximum value.

Drum Key EQ (Equalizer)
You can set Equalizer parameters for each Drum Key.
The following two screens are available. These
parameters are the same as for Normal Voices; details
are given on Page 86.
