Amp Env (Amp Envelope)
These parameters specify the depth of the amp envelope (change in volume over time) and the shape of the envelope itself.

Description
Curve by which pad playing dynamics will affect the volume of the tone
If you specify "FIX," the volume of the tone will remain the same regardless of your playing dynamics.
1 2 3
Amount by which pad playing dynamics will affect the volume of the tone
Specify a positive (+) value if you want the volume of the tone to increase as you play more strongly.
Specify a negative (-) value if you want the volume to decrease.
Amount by which T1 (time) of the Amp envelope will change in response to your playing dynamics
Increasing this value will produce a greater change between softly played and strongly played notes.
Specify a positive (+) value if you want the T1 time to speed up, or a negative (-) value if you want it
to slow down.
Amount by which T4 (time) of the Amp envelope will change in response to the speed at which you
release the pad (key-off velocity)
Increasing this value will produce a greater change between slowly released and quickly released
notes. Specify a positive (+) value if you want the T4 time to speed up, or a negative (-) value if you
want it to slow down.
Amount by which Amp envelope times (T2–T4) will be affected by the pad you play
Higher settings for this value will produce a greater change relative to the C4 key. Positive (+) values
will cause the times to become shorter as you play toward the right. Conversely, negative (-) values
will cause the times to become longer.

Amp envelope times (T1–T4)
Higher settings of these values will lengthen the time over which the next volume level of the enve-
lope is reached. (For example, T2 is the time over which the level changes from L1 to L2.)
* Realtime modify knob [A] adjusts Time 1, knob [D] adjusts Time 3, and knob [R] adjusts Time 4.
Amp envelope levels (L1–L3)
Specifies the change in volume at each point, relative to the reference level.
* Realtime modify knob [S] adjusts Level 3.
